Nantes, France, March 8, 2005 Atmel Corporation, a global leader in the development and fabrication of advanced semiconductor solutions, announced today their new AT89LP family, based on a Single-Cycle 8051 Core. Twelve times faster than the standard 8051 core, this new family extends the existing range of 8051 Flash microcontrollers.

These new devices are targeting low power 8051 applications such as white goods and battery-operated applications. Operating voltage range is 2.0V to 5.5V.

The AT89LP CPU requires only one clock cycle for every byte fetch. The AT89LP core is capable of 20 MIPS peak throughput at 20 MHz clock frequency using only the single-cycle instructions.

"With the new products, system designers enjoy up to 85% decrease in power consumption compared to classic 8051 microcontrollers at the same MIPS performance level," said Manish Vadher, Atmel's Marketing Director. "Atmel Single-Cycle AT89LP Flash microcontrollers are easy to use, and offer a rich and powerful instruction set at a great performance."

The AT89LP family includes:

  • 2 to 64 Kbytes of on-chip Flash memory, . The include on-chip DataFlash®,
  • internal RC oscillator
  • 10-bit ADC
  • analog comparator
  • pulse width modulators
  • programmable watchdog timer
  • UART
  • 14, 20, 28 and 44-pin packages

Pricing and Samples
The first two devices of the family are the AT89LP2052 and AT89LP4052. Housed in 20-pin PDIP, TSSOP, SOIC packages, they feature 2 Kbytes and 4 Kbytes of Flash code memory, respectively. They are pin-compatible with the existing AT89C2051 and AT89C4051. Samples are available now with production in 2Q05. Pricing for 10,000 units is $0.85 for the AT89LP2052 and $0.99 for the AT89LP4052. In-system Programming of these devices is supported by the AT89ISP programmer, which has a retail price of $25.
