Atmel unveiled the AT89C51RE2, a new 8051-based microcontroller, with 128 Kbytes of Flash programme memory. The device is an addition to the existing 16-, 32-, and 64-Kbyte 8051 Flash family of AT89C51RB2/RC2/RD2/ED2 microcontrollers, which have become an industry standard.
The AT89C51RE2 comes with a rich feature set including 8-Kbytes 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 ideally 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 5.5 volts and from 2 to 40 MHz, and achieves a 4 MIPS throughput when running at 40 MHz.
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.
Availability and Dev Tools
The AT89C51RE2 is available from Soanar - Electronic Component & Supply Chain Solutions in 44-pin PLCC and VQFP packages. Atmel offers the AT89STK-11, a starter kit, 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 soon too.
