16bit ‘Tough’ MCUs Optimized for Rechargeable NiMH Applications

LAPIS Semiconductor, a member of the ROHM group, has announced the development of the ML620130 family of 16bit low power MCUs, optimized for compact industrial equipment requiring battery drive in noisy environments, featuring superior processing capability with low power consumption.

In addition to clearing the ±30kV noise measurement limit, operating voltage has been successfully reduced to 1.6V. Optimizing the operating voltage to an integral multiple of standard nickel metal hydride batteries (NiMH, 0.8V× 2=1.6V) ensures efficient use without wasting battery charge. This contributes to decreased battery consumption, prolonging battery life in portables and battery-equipped industrial equipment. The ML620130 family consists of 9 models offered in a variety of memory capacities, pin counts, and other characteristics that make it possible for users to select the ideal solution to fit set needs.

To provide increased miniaturization and lower costs, many applications are opting to eliminate noise and/or thermal countermeasures. However, this makes it difficult to balance the conflicting demands for increased environmental resistance while maintaining safety utilizing fewer external parts. In addition, reducing the size of the battery mounted in the module while also increasing battery life requires that the power consumption (voltage and current) be optimized for each application.

To meet these disparate needs, LAPIS Semiconductor has expanded its lineup of market-proven 16bit low power microcontrollers to include the ML620130 family of ‘tough‘ MCUs that incorporate multiple functions optimized for battery drive operation.
