Atmel launches six new 8051 single-cycle core MCUs, reducing power consumption by 80% [Copy link]

Atmel has announced the launch of four 14-pin and two 16-pin new microcontrollers based on its 8051 single-cycle core . Atmel's single-cycle core architecture requires only one clock cycle to read a byte, allowing 70% of instructions to be executed within one clock cycle. This not only improves performance by 12 times, but also reduces power consumption by 80% compared to traditional 8051 devices. Low pin count microcontrollers have become the fundamental building blocks for many general purpose applications. The AT89LP213/413, AT89LP214/414 and AT89LP216/416 devices are cost-effective 8-bit microcontrollers that reduce system cost and time to market for white goods, remote controls, smart sensors and disposable electronics. The AT89LP214 and AT89LP213 have 2Kb of in-system programmable flash memory, while the AT89LP414 and AT89LP413 have 4Kb of flash memory. The AT89LP216 and AT89LP416 are 16-pin versions with 2Kb and 4Kb of flash memory, respectively. These devices have a rich feature set, including on-chip debugging, on-chip hardware multiplier, pulse width modulation, analog comparator, built-in RC oscillator and 12 sets of general application I/O. They can be widely used in motor control, battery management and other general applications. These devices can achieve 20MIPS throughput at 20MHz, while consuming very low power at lower frequencies. In 1MHz, 3.6V active mode, they typically consume 1.1mA, and in idle mode they consume less than 0.45mA. They can operate at voltages as low as 2V at 10MHz and 2.4V at 20MHz. 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 10k unit price for the AT89LP214 and AT89LP213 is $0.87, and the AT89LP216 is $0.91. Samples of the AT89LP414, AT89LP413 and AT89LP416 will be available in the fourth quarter of this year.
