Analog Devices: New Blackfin Family - Fast, Low Power and Cheap


Now available, the ADSP-BF533 delivers 600-MHz, 1.2 GMACS (Giga Multiply ACcumulate operations per Second) at only 280mW; the ADSP-BF531, also available now, sets new price performance level with 300MHz, 600 MMACS for $4.95 (10kU).


All new members of the Blackfin processor family are pin-for-pin and code compatible and offer new levels of peripheral integration, including glue-less connection to an array of ITU-R 656 video encoders and decoders, as well as high-speed analog-to-digital (ADC) and digital-to-analog converters at up to 65 MSPS (mega samples per second). The dedicated video port on all members of the family is supported by an innovative 2-dimensional DMA structure that significantly reduces software overhead and system power consumption for real-time video applications. Two dedicated serial ports support up to eight channels of IIS (I2S) audio.

Samples of all new members of the Blackfin processor family are available now in BGA packages. All Blackfin processors integrate on-chip memory, a dedicated video port and extensive I/O. Data sheets are available at with complete product specifications.

ARM Announces AMBA SystemC Interface to Enable System-Level Design


ARM announced the availability of the AMBA™ 2 Transfer-Layer SystemC interface specification. The specification is the culmination of a collaboration involving ARM, Synopsys, Inc., Cadence Design Systems, and CoWare Inc., to deliver a standard for connecting system-level design IP. The new methodology will enable designers of complex systems to use IP built according to the interface specification for the exploration of AMBA methodology-based SoC architectures. By using this methodology along with matching RTL IP for AMBA components and a System-to-RTL verification methodology, customers can reduce time-to-market for AMBA technology-based designs.

The Open SystemC Initiative (OSCI) is an independent, not-for-profit organization composed of a broad range of companies, universities and individuals dedicated to supporting and advancing SystemC as an open source industry standard for system-level design. The SystemC platform, that includes the SystemC specification source code and reference manual, can be downloaded at

Dallas 8051 Network Microcontroller Emulation Support


High-end emulation support for the Dallas  DS80C400 Ethernet Microcontroller (see our Nov 2002 story) has now been released by Metalink.  The MetaICE-XF is one of the smallest full-featured emulators on the market, measuring just 3.3" (8,4 cm) by 3.0" (7,6 cm). The DS400 MetaICE-XF emulator includes the following standard features:


  • 2 MByte Code Memory / 2 MByte External Data Memory

  • 512 K Frames of Trace Memory with Time Stamp

  • SFR Write Data in Trace Memory

  • Hardware Breakpoints

  • Full support of the on-chip ROM functions and capabilities

  • Up to 40MHz CPU operation

The SFR Write Data is a unique feature of the MetaLink emulator. This feature captures in the emulator’s trace memory every direct data write to an SFR (Special Function Register) in real time. It provides unparalleled visibility into the internal data flow of the program’s execution, which significantly enhances the debug capabilities of the emulator and the productivity of the engineer.

The DS80C400 contains Enhanced Hooks, a MetaLink patented emulation technology licensed to Dallas Semiconductor. Many of the DS400 MetaICE-XF emulator’s unique and powerful characteristics are a result of Enhanced Hooks being embedded in the DS80C400 microcontroller.

Metalink emulators are available at: The MicroController & Embedded Systems Shop

Fujitsu Releases the MB90330 Series of 16-bit USB Microcontrollers

Fujitsu announced the release of four new products in its MB90330 Series of 16-bit microcontrollers, which include a 12Mbit USB interface, integrating simple host features. The simple host feature enables direct USB communication without a host PC between audio-visual equipment (e.g. digital camera) and other peripherals (e.g. printer). All new family members operate from 3.0V to 3.6V, -45C to 80C and have a min instruction cycle time of only 41.6ns at 6MHz clock, thanks to an integrated PLL. Other features include a 16 channel 8/10-bit A/D, UART, I2C, Serial I/O (SPI), a range of timers, DMAC and external bus support.


The MB90F334 features 24kBytes of RAM and 384 kBytes of FLASH; the MB90F337 has 4kBytes of RAM and 64kBytes of FLASH, while the MB90333 has 16kBytes of RAM and 256kBytes of ROM and the MB90337 comes with 4kBytes of RAM and 64kBytes of ROM.

Fujitsu: CAN microcontrollers with LIN interface


Fujitsu has released a new extension to its 16LX CAN microcontroller family. The MB90340 series features single and dual CAN devices with LIN interfaces and extensive enhanced features. The standard operating temperature range is - 40 to +105°C, Flash memory is speced at 10,000 write/erase cycles, and a security element prevents unauthorized reading of the flash memory contents.
The MB90340 series is designed in 0.35 micron technology. Additional features include an optimized 4 channel LIN USART interface to offer flexible baud rate generation, multi-master modes and SPI interface. In addition, a wake-up CAN interrupt, embedded Debug Support Unit, Clock Modulator to reduce EMI, up to 24 analog channels, an increased number of PWMs and Timers, and faster power-on start-up time are also included.

Currently under development are several derivatives of the MB90340 series with one or two CAN Interfaces, I2C bus, and 16 or 24 analog input channels. The MB90F347 in a 100-pin QFP package with 1 CAN, 128KB Flash and 6KB RAM, and the MB90F342 in 100-pin QFP package with 2 CAN, 256KB Flash and 15.75KB RAM. Devices with 3 CAN interfaces and Flash sizes up to 512KB are planned.

Microchip: Seven New Low Power PIC16F Controllers


Microchip announced seven new low power devices for its PICmicro PIC16F Flash microcontroller family. The PIC16F627A, PIC16F628A, PIC16F648A, PIC16F818, PIC16F819, PIC16F87 and PIC16F88 microcontrollers feature a clock system with up to three enhanced "software controlled" power-managed modes. This enables users to control the speed of code execution. New low current modules include a watch-dog timer, brown-out reset and timer.

Motorola: New HCS12 Micro with 2k Calibration RAM

The new MC9S12T64 microcontroller unit (MCU) includes a 16-bit central processing unit (HCS12 CPU), 64K bytes of Flash EEPROM, 2K bytes of RAM, 2K bytes of CALRAM (Calibration RAM), two asynchronous serial communications interfaces (SCI), one serial peripheral interface (SPI), an 8 channel IC/OC enhanced capture timer, an 8-channel 10-bit analog-to-digital converter (ADC), an 8-channel pulse-width modulator (PWM), 25 discrete digital I/O channels (Port A, Port B, Port E and Port K). System resource mapping, clock generation, interrupt control and bus interfacing are managed by the System Integration Module (SIM). The MC9S12T64 has full 16-bit data paths throughout. However, the external bus can operate in an 8-bit narrow mode so single 8-bit wide memory can be interfaced for lower cost systems. The inclusion of a PLL circuit allows power consumption and performance to be adjusted to suit operational requirements.

The device comes in a 80 lead LQFP (12mmx12mm 0.5mm pitch) package and costs US$7.00 in 10kU quantities. Production start in Q3/2002.
