welcome to the March 2004 edition of MicroController Pros Corporation's Embedded News Digest, your source for microcontroller and embedded system news.
We intentionally delayed sending out this newsletter for a few days to be able to include all the news from the Embedded Systems Conference in San Francisco that ended yesterday (04/01).
This month's issue:
The new AT90CAN128 integrates in a single chip the features of the existing mega128 and the already proven V2.0A/V2.0B CAN controller used in the Atmel CANary microcontroller family. The CAN controller can handle 15 independent message objects, programmable on-the-fly.
On-chip features include: 16 MIPS AVR RISC-engine, 128-Kbyte Flash program memory, 4-Kbyte RAM and 4-Kbyte on-chip EEPROM, 16-bit timers with enhanced Pulse Width Modulation capabilities, a 10-bit/8-channel A/D converter and several serial interfaces. A wide operating voltage range (2.7V-5.5V) plus five low-power management modes optimize the application's power consumption.
In-Application Programming capability, via CAN, UART or SPI, allows remote programming and field upgrades. Atmel offers a library of In-Application Programming routines to customers wanting to build their own bootloaders, reducing overall development time and thus time-to-market.
AT90CAN128 is pin-to-pin compatible with the mega128. It is available in TQFP64 and QFN64 packages and in industrial temperature. Samples are available now. Production volumes are expected in June 2004. Pricing for 10,000-unit quantity per year is $7.50.

NEC introduced two series of single-chip microcontrollers (MCUs) for inverter-control applications, the uPD78F0714 and V850ES/IK1.
The uPD78F0714 operates at 20 MHz and is the latest addition to the company's 78K0™ family of 8-bit MCUs. The device offers 32 kilobytes (K) embedded flash memory and 1K random access memory (RAM), along with dedicated 3-phase inverter functions and an on-chip debug (OCD) function that allows developers to design and debug products in circuit via a serial connection.
The V850ES/IK1 is comprised of three products: the uPD70F3329 with128K of flash memory and 6K RAM, the uPD703327 with 64K of mask read-only memory (ROM) and 4K RAM, and the uPD703329 with 128K of mask ROM and 6K of RAM. They also include dedicated peripherals for 3-phase inverter control.
Both the uPD78F0714 and V850ES/IK1 series come with a number of safety features necessary for motor-control applications. These include an emergency shutdown pin for the inverter timer outputs to protect the motor and inverter, and a power on clear (POC) and a low voltage interrupt (LVI) for a controlled system shutdown and recovery in the event of power failure.
The V850ES/IK1 and uPD78F0714 MCUs are scheduled to start sampling in May and June 2004 respectively. For orders in 10,000-unit quantities, pricing is expected to start at US$17 for the V850ES/IK1 controller with flash (uPD70F3329); US$6 for the V850ES/IK1 controller with 128K of mask ROM (uPD703329); US$5 for the V850ES/IK1 controller with 64K of mask ROM (uPD703327); and US$4 for the uPD78F0714 controller. Mass production is scheduled to start in November 2004
Renesas announced the four 20-pin package version groups of R8C/14, R8C/15, R8C/16, and R8C/17, as third-phase products in the R8C/Tiny Series of low-pin-count, small-package, 16-bit microcontrollers with on-chip flash memory. There are three models in each group, for a total of 12 models.
Features of these new groups are summarized below.
New functions not provided in previous R8C/Tiny Series models are a synchronous serial I/O function with a chip select facility (SSU) and an I2C bus interface. The SSU function is provided in the R8C/14 Group and R8C/15 Group, and the I2C bus interface in the R8C/16 Group and R8C/17 Group.
All groups include an 8 MHz-standard high-speed ring oscillator. This oscillator enables programmable frequency adjustment to be carried out by rewriting an internal register, and the inclusion of a correction circuit provides frequency precision of ±3% or better.
The R8C/15 Group and R8C/17 Group include two 1-Kbyte data flash blocks that can be erased a minimum of 10,000 times. 16, 12, or 8-Kbyte on-chip flash memory for software storage is available in each group.
