Atmel Extends its Flash Microcontroller Family With a New 128Kb Device
Atmel® Corp. announced the AT89C51RE2, a new 8O51-based microcontroller with 128Kb of Flash program memory. The device is an addition to the existing 16, 32, and 64Kb 8O51 Flash family of AT89C51RB2/RC2/RD2/ED2 microcontrollers which have become an industry standard.
The AT89C51RE2 comes with a rich feature set including 8Kb of RAM, two UARTs, watchdog timer, power-on-reset, power-fail detector, PCA, SPI and on-chip debug, and up to fifty general-purpose I/Os for application use. The device is well-suited for industrial and consumer applications such as I/O management, power management, industrial and motor control, smart sensors and set-top boxes. The AT89C51RE2 can operate from 2.7 to 5.5V and from 2 to 40MHz and achieves a 4 MIPS 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 USD $4.80 for 10k units. Atmel offers the AT89STK-11, a starter kit for USD $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.
