The AT89LP214, AT89LP213, AT89LP216, AT89LP416 the New Single-Cycle Atmel 8051 Microprocessors

Atmel Corporation announced four Atmel 8051 single-cycle  microcontrollers. Atmel’s single-cycle core architecture executes each byte fetch in a single clock cycle resulting in 70 percent of all instructions being executed in a single clock cycle. Compared to the traditional 8051 devices, this can either increase performance up to 12 times or reduce power consumption by up to 80 percent.

The AT89LP214 and AT89LP213 have 2 Kbytes of In-system Programmable Flash whereas the AT89LP414 and AT89LP413 have 4 Kbytes of Flash. The 16-pin versions are the AT89LP216 and AT89LP416, which have 2 and 4 Kbytes of Flash memory respectively. These devices come with a rich feature set which includes on-chip debug, on-chip hardware multiplier, Pulse Width Modulation, analog comparator, internal RC oscillator and 12 general-purpose I/Os for application use.

The devices achieve a 20 MIPS throughput when running at 20 MHz and consume very low power when running at a lower frequency. Typical power consumption in 3.6V active mode at 1 MHz is 1.1 mA and less than 0.45 mA in idle mode. They can operate down to 2V at 10 MHz and 2.4V at 20 MHz.

The AT89LP214 and AT89LP213 are available in 14-pin TSSOP and PDIP packages while the AT89LP216 is available in 16-pin TSS0P, SOIC and PDIP packages. The 10,000-unit price is $0.87 for AT89LP214 and AT89LP213, and $0.91 for AT89LP216. Samples for AT89LP414, AT89LP413 and AT89LP416 will be available in Q4 2006.
