This month's issue:
ARM announced its new DesignStart™ program, which will provide
chip developers with access to the ARM7TDMI® processor core for the TSMC, UMC,
SMIC and Chartered Semiconductor process technologies. This program allows free
access to a web version of the Artisan® Design Environment for the ARM7TDMI
processor. It will enable design teams to gain instant access to ARM IP without
the need to acquire costly design software or licenses up-front, thus allowing
them to rapidly design and validate their system-on-chip (SoC) designs.
The web-based design kits enable engineers to complete the design
process all the way through chip-level verification. Once the design is finished
and ready for fabrication, a single-use design license can be purchased to
receive a full set of deliverables and thus enable tape out and manufacture at
any of the supported foundries.
Crossware has released version 3 of its C
Compiler for Freescale's ColdFire microprocessors and microcontrollers. The new
compiler, available as part of Crossware's
ColdFire Development Suite, will simplify development and increase the speed
of compiled programs.
The new compiler is able to carry out a flow analysis of a program and use this
analysis to perform optimizations that are not otherwise possible. Also,
additional calling conventions (ways in which the function call and function
return are coded) have been added and these can be used to further increase the
speed of the compiled program. In addition, function parameters can be passed in
registers and function in-lining can be used to completely eliminate the
function call altogether.
Crossware has also developed a range of
facilities to test the compiler and the libraries that come with it. A special
version of Crossware's Embedded Development Studio is capable of automatically
generating, compiling and executing complex expressions. The code produced is
self-checking and execution will halt if a result is incorrect. Similarly,
self-checking code can be automatically generated to test library functions, and
randomly generated input data ensures that the library functions operate
correctly with a wide range of inputs.
The new compiler is available as part of Crossware's ColdFire Development Suite
and includes a C compiler assembler, linker, simulator and debugger all
integrated into an easy-to-use development environment. A USB BDM (background
debug mode) interface is also available to complete the set of development
Microchip Technology has announced the first 10 members of

Microchip Technology has introduced the
world's smallest Ethernet controller, designed to allow creation of
network-enabled embedded applications with minimal board space requirements.
The IEEE 802.3-compliant 10 Mbps ENC28J60 features a
standard SPI interface, a programmable 8-Kbyte Dual-Port SRAM Buffer, and
special filters. These include Microchip's programmable pattern-matching filter,
and can automatically evaluate, accept or reject Magic Packet, Unicast,
Multicast or Broadcast packet types, minimizing the host microcontroller’s
Limited sampling for the ENC28J60 Ethernet controller is
available now, and volume production is expected in May. Options include 28-pin
SPDIP, SOIC, SSOP and QFN packages.
Renesas Tannounced the SH-MobileJ3 (product
name: SH7326) featuring 4-megapixel camera support and on-chip image processing
hardware accelerators as a new model in the SH-Mobile*1 Series of mobile phone
application processors, for use in mid-range mobile phone system models.
The SH-MobileJ3 is the successor of the
current SH-MobileJ2 for mid-range mobile phone models, and offers enhancements
of major image processing functions.
The number of camera interfaces has been increased to two, upgraded to
high-definition 4-megapixel camera compatibility. For example a mobile phone
incorporating a camera and TV tuner that previously required the addition of
external circuitry can be implemented using an SH-MobileJ3 without the need for
such circuitry, enabling system costs to be reduced.
A MPEG-4 full hardware accelerator is
included for moving image processing, for still image processing, the
SH-MobileJ3 features the inclusion of a JPEG hardware accelerator.
The SH-MobileJ3 incorporates an LCD
controller supporting TFT color liquid crystal panels, a video output unit
capable of outputting moving images shot with a camera to a TV set, a Version
1.2a compliant IrDA interface, a USB2.0 Function (Full Speed compliant) module,
a keyboard interface, and a memory card interface.
The capacity of flash memory connectable to a NAND/AND flash memory interface
has been substantially increased from the maximum 512 Mbits of the previous
product to 4 Gbits.
The package used is a 281-pin CSP (9 mm x 11
mm x 1.4 mm, 0.5 mm pin pitch), an SiP with on-chip 128-Mbit SDRAM that requires
a smaller mounting area. Price in 10000 unit quantities is 3500 Yen.
TI has announced the introduction of the
MSP430F42x0 generation of microcontrollers, a low-cost, signal-chain-on-a-chip (SCoC)
MCU solution for high precision sensing and measurement applications. The
MSP430F42x0 MCU features an ultra-low-power core and a complete chain of
integrated peripherals such as a 16-bit sigma delta analog to digital converter
(ADC), up to 32KB of flash memory and a liquid crystal display (LCD) driver with
an internal charge pump.
The integrated 16-bit ADC has five
differential input channels, up to 8,000 samples per second and a typical
signal-to-noise and distortion ratio of 84 dB. This, combined with the 12-bit DAC's 1 microsecond settling time, lets designers leverage closed loop control
to achieve the high levels of measurement and accuracy. The 16-bit ADC has a
programmable gain amplifier, 1.2 voltage reference and an input buffer to
eliminate the need for external signal conditioning for most applications. All
of the peripherals have an option to minimize power consumption. The integration
of up to 32KB of flash memory and LCD driver that maintains contrast control
down to an input voltage of 2.2V reduces board space and build of materials by
removing the need for an EEPROM and external LCD charge pump.
MSP430F42x0 MCUs are designed to work in the
harsh environments typically found in industrial and medical applications. When
a crystal fails due to moisture or a foreign substance during active or any
low-power mode, the MSP430F42x0 is able to acknowledge the failure, re-start the
on-chip clock system oscillator and generate a non-maskable interrupt to service
The MSP430F4270 MCU's 2.5 minimum voltage for flash in-system programming &
erasing and 16-bit ADC extends the life of alkaline-battery-powered systems by
50 percent. The zero-power brown-out reset function is designed to reset the
MSP430 during a low-voltage condition below specification preventing
unpredictable behavior on the device.
MSP430F42x0 MCUs are specified for operation
from 1.8 V to 3.6 V and are fully software-compatible with all existing MSP430
devices. The MSP430F4270 MCU will feature 32 KB of flash memory, with the F4260
and F4250 MCUs featuring 24 KB and 16 KB of flash memory, respectively. All
three devices include 256 Bytes RAM, and 32 I/O channels. Samples of MSP430F42x0
MCUs are available today with volume production in May 2005. Pricing will start
from $2.95 in 10,000-piece quantities (suggested resale pricing).
ZiLOG has rolled out F08xA, an 8KB Flash memory addition to its
Z8 Encore! XP microcontroller line. This addition extends the Flash memory range
of the Z8 Encore! XP family to include 1, 2, 4 and 8KB varieties. The Z8 Encore!
XP F08xA Series is based on the eZ8 CPU and supports 8KB of Flash program memory
and 1KB registered RAM. The devices feature up to eight
single-ended/differential channels of 10-bit A/D conversion and a
trans-impedance amplifier for current measurement. An on-chip temperature sensor
allows die temperature measurement over a range of -40 degrees to +105 degrees
C. These devices also include two enhanced 16-bit timer blocks featuring PWMs
and Capture and Compare, and up to 18 vectored interrupts with programmable
priorities provide increased application flexibility.
The new series also features an on-chip internal precision
oscillator (5MHz/32KHz) as a trimmable clock source that requires no external
components. A new single-pin debugger and programming interface simplifies code
development and allows for easy in-circuit programming, and a full-duplex UART
provides serial communications and IrDA encoding and decoding capability.
Available now, the Z8 Encore! XP F08xA Series sells for $1.63
for a 28-pin SOIC with an A/D Converter, and $1.50 for a 20-pin SOIC without an
A/D Converter, each in quantities of 1,000. Development kits for each will be
available through ZiLOG's distribution channels.
