16-bit MCUs integrate 256KB flash memory

These MCUs combine a proprietary 16-bit low-power CPU core with a newly developed successive approximation AD converter featuring 1.25µs conversion speed and a high accuracy (±1%) oscillation circuit, ensuring efficient processing of multiple analogue inputs and operations requiring high oscillation accuracy such as mutual data communication between devices without the need for an external oscillator, making it possible to configure simpler systems.

Specifically, this allows support for applications that utilise networks in the future, such as serial communication that enables wireless connection with HEMS/BEMS equipment and multi-channel analogue input for motion, temperature, pulse, and other biological sensors used in health care equipment, as well as conventional sensing and actuation that contribute to greater energy savings and convenience in today’s home appliances and electronics.

The lineup consists of six models, available in three different pin counts (64-/80-/100-pin) and two internal flash memory capacities (128/256kB), making it possible to meet a wide range of needs, including for greater application functionality and increased software capacity.

In recent years, expanding application functionality, combined with the increased adoption of networks to support multi-sensing operation following the proliferation of sensors and HEMS/BEMS, have resulted in greater demand for MCUs featuring higher performance and efficiency along with lower power consumption.

In response, LAPIS Semiconductor expanded its ML620500 series of 16-bit MCUs based on market-proven proprietary low power technology by adding six models that provide enhanced functionality and higher capacity.
