Atmel Corp. has beefed up its 8051-based MCU line with the launching of AT89C51RE2, a new MCU with 128Kbytes of flash program memory. The device is an addition to the existing 16-, 32- and 64Kbyte 8051 flash family of AT89C51RB2/RC2/RD2/ED2 MCUs.

The AT89C51RE2 comes with a rich feature set including 8Kbytes of RAM, two UARTs, watchdog timer, power-on-reset, power-fail detector, PCA, SPI and on-chip debug, and up to 50 GPIOs for application use. The device is aimed at industrial and consumer applications such as I/O management, power management, industrial and motor control, smart sensors and STBs. The AT89C51RE2 can operate from 2.7V to 5.5V and from 2MHz to 40MHz and achieves a 4MIPS throughput when running at 40MHz.

A key new feature is the on-chip debug (OCD) capability that enables low cost emulation. The hardware debug system with Windows IDE interface allows the user to access debugging functions built into the AT89C51RE2, resulting in faster development and verification of user code in real-time.

The AT89C51RE2 is available in 44-pin PLCC and VQFP packages at $4.80 for 10,000 units.

Atmel offers the AT89STK-11, a starter kit for $99, to evaluate the AT89C51RE2; designers can either run the demonstration program or their own application. A new low-cost on-chip debug tool, AT89OCD-01 will be available by the end of November 2006.
