This month's issue:
At a 300 MHz clock rate, the ADI's ADSP-TS101S offers the DSP industry's best 1.8 GFLOPS (billion floating-point operations per second) and 2.4 GMACS (billion multiply accumulates per second) 16-bit fixed-point performance as well as a 32-bit floating-point 1024 complex FFT time of 32.9 microseconds. The ADSP-TS101S offers a complete set of on-chip features such as a large 6 Mbit internal memory, 14-channel zero-overhead DMA engine, and 1.8 Gbyte I/O throughput.
TigerSHARC processor's two types of integrated multiprocessing
support (link ports and a cluster bus) enable glue-less scalability and
unmatched I/O performance. The 32/64-bit cluster interface enables scaling of up
to eight devices into a DSP system without the need for bridge chips or
supporting logic. In turn, the link ports provide a high bandwidth
point-to-point multiprocessing connection that is complementary to the cluster
ARM Holdings plc announced that more than 25 partners have signed
up to provide support and technical contributions toward the development of the
next generation of its advanced microcontroller bus architecture (AMBA), AMBA
Atmel announced the availability of a UHF RF wireless on/off key transceiver chip set based on Atmel's AT86RF401 Smart RF micro transmitter and its T5744 receiver. The micro transmitter's AVR-based core enables it to be paired with the T5744 receiver and supervise 2-way on/off keyed communications in the unlicensed ISM band (300MHz - 450MHz). With +6dB of output power on the micro transmitter and -110dB of input sensitivity on the receiver, a high performance, low-cost, 2-way RF wireless system can be realized. These features make this chip set ideally suited for low-cost, low-data rate, 2-way remote sensing applications, such as temperature, pressure, and motion, as well as remote control applications, like home appliance and lighting, energy management and monitoring, and security systems.
The AT86RF401 Smart RF micro transmitter contains an AVR microcomputer with 2KB of Flash program memory and 128B of EEPROM data memory. The integrated PLL-based RF transmitter is intricately linked to the AVR core. This places many key RF parameters, including VCO tuning, output power, and carrier modulation, under software control.
The chip set is available now in TSSOP20 (TX) and SO20/SSO20 (RX)
packages. Chip set pricing starts at $3.23 per pair @ 10,000 units.
Did you think Embedded Systems are by principle more secure than general purpose computers? Well, it seems that at least some embedded system programmers are no better than their colleagues at Microsoft and treat security as an afterthought.
Security Experts demonstrated significant security holes in Embedded Systems during the 19th Chaos Communication Congress in Berlin. An HP LAN network printer running the Java based ChaiVM software could be reconfigured so that it send all printed documents or documents from selected persons to an email address even through a firewall. (www.phenoelit.de/hp/)
CISCO network routers can be reconfigured or significantly loaded down with buffer overflow exploits (www.phenoelit.de/ultimaratio).
Fairchild Semiconductor's ACE1502 integrates an ACEx family core (similar instruction set to National Semi's COP8 family) with 2KB of code EEPROM, 64 bytes each of SRAM and data EEPROM, an on-chip clock generator, and an I/O port with high current (±7mA) on each of the I/O pins. The device is specified for an operating voltage of 1.8V to 3.6V. Available in eight-lead and 14-lead configurations in SOIC and TSSOP packages, the chip does in-circuit programming without requiring a higher programming voltage. It also has a brownout reset function and 32-level low-voltage detection.
This one escaped us in November: Early November Fujitsu announced
the introduction of its new FR60Lite series of microcontrollers. Designed to
consume less power, the new series is the latest addition to the FR family of
32-bit RISC microcontrollers. The first two FR60Lite products (the MB91F233 and
MB91232L) both come with embedded LCD controllers and support the same
high-speed 33 MHz operation as their predecessors, but in a smaller package.
By optimizing the clock-driving circuitry, power consumption of the CPU core has
been slashed to 1 mA per MHz, a 40% reduction compared to the existing
microcontrollers based on the 32-bit RISC CPU core.
The new H8S/2674R has an on-chip 32KB SRAM and a hardware
multiply-accumulate (MAC) unit that enables the MCU to run DSP-type software
applications up to three times faster than other 33MHz H8S chips without
hardware MACs. Using the MAC, the H8S/2674R running at 33MHz executes a
16x16-bit multiplication operation in only 120 nanoseconds.
In addition to all the already earlier supported AVR derivatives, this new version of the IAR Embedded Workbench includes support both for the new ATmega8535, ATmega32, ATmega162 and ATmega169 derivatives and for the Atmel JTAG ICE, which is completely integrated into the IAR Embedded Workbench. The IAR Embedded Workbench includes support for both the ICE 200 in-circuit emulator and the JTAG ICE interface, a complete mid-range and high-end device support, and an C/Embedded C++ compiler. A "Pro" version of the toolkit adds a graphical system design tool, a system design test tool and an automatic design documentation tool.
Microchip Technology Inc. introduced its new MPLAB Integrated Development Environment (IDE) v6.10 software. Designed for use with Microsoft Windows, the MPLAB IDE environment integrates various aspects of development, including source code editing, project management, machine code generation (from assembly or "C"), fast device simulation, device emulation, and device programming. Features of the interface include a full-featured, color-coded text editor; project manager with visual display; enhanced source level debugging for "C"; a dynamic status bar to display processor condition; and context sensitive, interactive on-line help.
The MPLAB IDE software is available at no cost and is downloadable from Microchip's Web site at www.microchip.com/1010/pline/tools/picmicro/devenv/mplabi/index.htm.
Motorola introduced three new pin-compatible devices in its HCS12
microcontroller family: HC9S12A64, HC9S12D64 and HC9S12DJ64. All 3 devices have
the following common feature set: 25 MHz HCS12 core (40 ns minimum instruction
cycle); 64K bytes Flash memory
The HC9S12D64 includes a CAN2.0A interface and the HC9S12DJ64 a One Byte Data Link Controller (BDLC) serial communication module for the J1850 vehicle communication protocol.
The HC9S12A64, HC9S12D64 and HC9S12DJ64 are available now in a 112-lead low-profile quad flat package (LQFP) or 80 LQFP. Suggested list prices range from $7.00 to $8.30 (USD) for 1,000 or fewer pieces.

connectivity through a modem line; There are three alarm line inputs that may be
used to connect industrial standard alarm contacts. The alarm lines are designed
to recognize external manipulations, such as attempts to cut the wires or
shorten a line. The reference design is also engineered to enable connection to
several sensors and nodes in a home using a LIN (Local Interconnect Network)
CPU: 4 cycle 80C51 instruction set compatible core; Programmable
clock rate: DC/20MHz/40/60MHz; On-chip programmable PLL generates up to 60MHz
The first module in this family is the LMX9820 Serial Port
Module. The LMX9820 enables Bluetooth data connectivity via a UART serial port
to support applications such as access points, digital cameras, set-top boxes,
printers and scanners. Additional members of the Simply Blue family will be
introduced throughout 2003. All of National's Simply Blue products include an
embedded Bluetooth protocol stack, application-specific profiles and a
high-level command interpreter and are compliant with the Bluetooth V1.1
The COP8-REF-IA-01 reference design implements the functionality
of an Internet connected weather station. The board is connected to the Internet
via a dial-up modem. The COP8FLASH microcontroller based board measures
temperature, humidity, pressure and light intensity with its integrated 16
channel, 10-bit A/D and communicates this information via an Internet connection
to your PC running the supplied host software. The board also supports real-time
emulation and debugging of your Internet Application via the free COP8™
Development Platform featured on the included CD-ROM
The COP8-REF-IA board supports two modem options (modems not
included with kit): An external modem (standard PC type) connected to the
board's RS232 port, or an optional on-board modem module. The board features the
Similar to National Semi, Philips also announced a Bluetooth Module, called "TrueBlue" . Philips claims their product to be "the first to integrate embedded Flash along with all required Bluetooth functionality (baseband, radio) into a single, ultra-compact package (9.5 x 11.5 x 1.7 mm)". Well that's only true if you consider National's package of 10.1x14.0x1.9 to NOT be "ultra compact".
The BGB201 module combines baseband functionality with radio
functionality in a single integrated module. The baseband of the BGB201
Bluetooth module is a Blueberry baseband chip that integrates an ARM7
microcontroller with 224 kbyte of embedded flash memory and a variety of
interfaces, such as USB, UART, PCM, and GP I/Os on a single die. Additionally,
the BGB201 supports all existing Bluetooth data and voice packets and can be
connected with voice codecs already present in a device in order to enable voice
functions. In designs such as wireless headsets that have no voice codec, the
BGB201 works seamlessly with the newest 1.8 volt voice codec from Philips -- the
Blueberry Voice PCF87757 -- to create Philips’fully functional Bluetooth Voice
