welcome to this month's edition of MicroController Pros Corporation's Embedded News Digest, your source for microcontroller and embedded system news.
This month's issue:
The AMBA AHB Modeling Specification is a fully cycle-accurate representation of the AMBA AHB protocol. Designers of complex systems will be able to use the Interface Specification to explore detailed AMBA interconnect issues and co-validate their system models with RTL implementations. Besides full support of the AMBA AHB protocol, the Interface Specification includes the AHBlite protocol that is widely adopted for high-performance bus-matrix architectures.
The AMBA AHB Cycle-Level Modeling Specification is open and free of any charges. A is available now for download from the ARM® website at http://www.arm.com/armtech/AMBA. To protect the integrity of AMBA technology, the specification is made available under a simple license agreement broadly in line with the widely-accepted AMBA 2.0 specification licensing agreement.

Microchip introduced the rfPIC Development Kit 1, providing design engineers with an easy way to evaluate low-power radio frequency (RF) communication links for embedded control applications based on the its rfPIC12F675 Flash microcontroller plus UHF RF transmitter, and the rfRXD0420 receiver device.
Designed to work in tandem with the popular PICkit 1 Flash Starter Kit, the rfPIC Development Kit 1 consists of transmitter and receiver modules supporting the 315MHz and 433MHz frequencies. The receiver modules, featuring the rfRXD0420 device, plug directly into the PICkit 1 development board for demonstration and development. The modules are available separately so designers can create several prototypes based on the same module without having to develop an actual RF design.
Available today with 315/433 MHz Amplitude Shift Keying, pricing is $25 for the rfPIC receiver module, $30 for the rfPIC transmitter module, and $135 for a kit that includes two receivers, two transmitters and the PICkit 1 Flash Starter Kit.

NEC Electronics announced the availability of its new 32-bit microcontroller V850E/CG2 “CarGate-F”. Designed especially for high-end automotive applications, it offers five Full-CAN interfaces with 128 CAN message buffers and an on-chip floating-point unit, thus guaranteeing very high performance even for the most demanding gateway solutions.
Gateways are required to exchange information between the various in-car networks, for example to provide the engine temperature to the climate control system. Today’s cars feature up to five CAN networks. The resulting complexity of the network requires dedicated gateway microcontrollers tailored to high-performance routing tasks.
Based on NEC Electronics’ 32-bit V850 CPU core, the new gateway controller features 32 Kbytes of RAM and a 40-MHz clock speed. Furthermore, CarGate-F offers two timers, six 10-bit A/D converters, three CSIs and two LIN UARTs. The controller provides a high-speed 32-bit bus interface with five chip selects for the connection of up to 16 Mbytes of Flash or RAM per chip select. 8 kBytes of on-chip instruction cache secure high performance even with external code execution.
The new H8/36024F microcontroller operates at a maximum frequency of 20 MHz using a 3 to 5.5 V power supply. It offers a wide variety of on-chip peripherals, as well as the three on-chip USARTs. It has a 16-bit timer as well as an 8-bit timer, a 10-bit analog/digital converter, and a number of high-current I/O pins. The H8/36024F is available in two Flash versions, the H8/36024F with 32 kBytes of single supply on-chip Flash, and the H8/36022F with 16 kBytes of on-chip Flash. The device incorporates Flash memory that can be programmed and erased with a single power supply. A number of mask variants with mask sizes from 16-kbytes to 32-kbytes and a variety of SRAM sizes will also be available during 2003.
The RSC-4x features an 8 bit micro-controller with DSP assist engines, twin DMA's, 16 bit ADC with microphone pre-amp, 10 bit DAC with PWM speaker drivers, as well as 24 configurable I/O lines including 2 comparator inputs. A real-time clock, general purpose timer, a watch-dog timer, a zero cost on-chip RC oscillator are also included, along with and low battery detection. The ADC, DAC, PWM, digital filter are all customer accessible for added features and control. The RSC-4128 offers 128KBytes of on-chip, maskable ROM, with address space for up to 1MByte off-chip. 4Kbytes of RAM is on chip with sufficient memory to store speaker dependent or speaker verification templates. ROM-less versions and various memory sizes are offered throughout the RSC-4x family.
As a speech processor, the RSC-4x offers >97% recognition capabilities including robust performance in noisy environments and a large vocabulary of words and phrases. The RSC-4x also provides high-quality speech synthesis at varying data rates from 3K-64K bits per second. Included on chip is an 8-voice MIDI-like music synthesizer that supports voice overdubbing with music. Speech technologies include speaker independent, speaker dependent, speaker verification, and word spotting. Core speech modeling approaches include Neural Networks, Hidden Markov Modeling, Dynamic Time Warping, and other proprietary statistical and non-linear techniques.
The RSC-4x is supported by a complete suite of easy-to-use tools for both programming and speech processing. Programming tools are available from The MicroController & Embedded System Store (http://microcontrollershop.com), and include assembler, C-compiler, in-circuit emulator, and debugging/simulation tools, all designed for fast, bug-free programming under a user-friendly integrated development environment.
Zilog announced the availability of engineering samples of its Z8 Encore!(R) F08 (8KB Flash) and F04 (4KB Flash) microcontrollers. This new series of Flash microcontrollers extends the Z8 Encore! family which includes the previously released 16KB through 64KB devices.
The ZiLOG Z8 Encore! F08 and F04 devices feature 1KB of linear register SRAM, a 9-bit UART port with integrated IrDA encoder/decoder, two 16-bit counter timers and a 5 channel 10-bit A/D converter.
The new devices are packaged in SOIC and SSOP packages with 20 or 28 pins. The Z8 Encore! Z8F08 (8KB) will sell for $2.26 to $3.04 each in 1,000s (depending on configuration). The Z8F04 (4KB) costs $1.51 to $2.21 each in 1000s (depending on configuration).
