welcome to the April 2004 edition of MicroController Pros Corporation's Embedded News Digest, your source for microcontroller and embedded system news.
This month's issue:
Atmel announced the availability of the PC7447A microprocessor, the extended-reliability version of the MPC7447A from Freescale Semiconductor, a wholly owned subsidiary of Motorola Inc. Manufactured on Freescale Semiconductor's 130 nm silicon-on-insulator CMOS process technology, the PC7447A microprocessor can operate at up to 1420 MHz in a military temperature range of -55 degree Celsius to +125 degree Celsius. A low-power version of the PC7447A is also available at 1167 MHz with a power dissipation of 9.2 watts and less than 6 watts when the processor runs at 600 MHz.
The PC7447A features a 512-Kbyte on-chip secondary level (L2)
cache memory, full symmetric multiprocessing (SMP) support, a 64-bit bus
interface and AltiVec(TM) vector processing technology. The PC7447A
microprocessor is available for both industrial and military temperature ranges
in a 360-ball Hi-TCE Ceramic Ball Grid Array package.
Atmel announced that it has shipped its 500 Millionth AVR Flash Microcontroller. Atmel introduced the AVR 8-bit Microcontroller Architecture in 1997. According to Atmel, over the past six years, the AVR has become the industry's largest selling 8-bit Flash Microcontroller with a market share of now over 30 percent.
Please note the creative marketing at work: it's not the largest selling 8-bit microcontroller, but the largest selling 8-bit Flash Microcontroller. Atmel does not have a 30% market share of the 8-bit microcontroller market, but of the 8-bit Flash microcontroller market.
Just for comparison: Microchip announced the shipment of the 3 billionth PIC microcontroller (since 1989) on Feb 26th 2004, of which 2 billion where shipped between 1999 and 2004, but that number includes also a large percentage of OTP (non-Flash) microcontrollers.

Microchip is accepting registrations for its eighth annual Microchip's Annual Summer Technical Exchange Review (MASTERs) conference at the Westin Kierland Resort in Scottsdale, Arizona , July 21 – 24.
65 classes are being offered – 41 of which are new. The new classes are expected to give attendees an opportunity to learn about Microchip's latest product offerings and upcoming roadmaps. In addition to lecture-based classes, there are 30 hands-on workshops that enable attendees to practice what they have learned. Since the course materials are geared to varying skill levels, a rating system has been added to the registration form. Classes are rated from “1” to “4.” A designation of “1” requires only basic understanding of the topic, whereas a “4” is appropriate for engineers with more experience and/or knowledge in the concepts and basics of the technology being discussed in that class.
Entry to the MASTERs conference courses, a CD-ROM with all class material, and three-night accommodations with meal and evening entertainment are included in the Conference cost of $995 USD. All potential attendees must register by June 23. More information regarding the MASTERs Conference can be found online at: www.microchip.com/masters
Just in case you missed it (as we refer to Freescale for the first time in this newsletter): Motorola Semiconductor is no more, since February 13th 2004 the former semiconductor division is called Freescale Semiconductor, a wholly owned subsidiary of Motorola Inc. Motorola plans to "separate" from Freescale "later this year".
NEC has also arrived in the modern FLASH age with its latest Kx1+ series. Contrary to prior NEC FLASH micros the new Kx1+ series uses the SST SuperFlash technology that allows single voltage operation, in-system program updates and usage of the FLASH program memory for non-volatile user data storage.
See our article: The evolution of FLASH microcontrollers: FLASH Is Not Equal FLASH, for more information on this topic.
The 78K0/Kx1+ Series shares the same peripheral set as the older 78K0/Kx1 Family and increases clock speed by 60% to 16MHz.
Renesas announced the development of a 32-bit RISC CPU core, called the SH-2A. The SH-2A is the successor of the SuperH™ RISC microprocessor SH-2 core, and offers a major increase in performance together with improved program code efficiency.
The current SH-2 has a processing performance of 104 MIPS at the maximum operating frequency of 80 MHz, while the SH-2A achieves processing performance of 360 MIPS at 200 MHz - an approximately 3.5-fold improvement. Processing performance per 1 MHz unit frequency has been improved approximately 1.4-fold, from 1.3 MIPS to 1.8 MIPS, through the use of a superscalar architecture. In other words, an approximately 40% improvement in performance is achieved at the same operating frequency, and a lower operating frequency is required to achieve the same performance, enabling system power consumption to be reduced.
The instruction set of the SH-2A is upward-compatible with that of the SH-2. New 32-bit instructions and addressing modes have been added to the previous 16-bit instructions, and a total of 112 instructions are now supported, including 21 FPU (floating-point processing unit) related instructions.
Silicon Laboratories announced the C8051F350, which integrates an eight-channel, 24-bit analog-to-digital converter (ADC) with a high-speed (50MIPS) 8051-compatible CPU.

Based on the MIPS® R3000A architecture of MIPS Technologies, Inc., the new TX19A70 family features a newly developed 32-bit RISC TX19A core and includes both the 32-bit MIPS32® instruction-set architecture (ISA) for speed and the MIPS16e™ Application-Specific Extensions (ASE), an instruction set with high-code-efficiency which contains instructions added by Toshiba. Most instructions can be executed in a single cycle of 17.8 nanoseconds. Each execution unit (32-bit ALU, 32-bit MAC, 32-bit Shift) can execute an instruction in a single cycle.
The family has been optimized for motor control applications, featuring a built-in 2-channel, 3-phase PWM output with a dead timer for motor control. A 16-bit up/down counter can generate a PWM carrier frequency with a minimum resolution of 35.7ns. An EMG signal input makes emergency output shutdown possible. A 1-channel encoder counter that enables easy detection of the motor position
The family also integrates two 10-bit sequential conversion type A/D converters with a conversion time of 2.36 microseconds. The A/D converters can synchronize with the PWM or a timer and can start A/D conversion at any location in the PWM output. Other features include 2 UARTs and 1 synchronous serial/Uart (switchable) channel. By multiplying the frequency of an external 7MHz oscillator by a factor of 8 (=56 MHz), 1-cycle instructions can be executed in 17.8ns
