16-bit MCUs with Improved Noise and Temperature Capabilities

January 28, 2015 By admin Comments are Off

LAPIS Semiconductor, a ROHM Group company, has announced the development of the ML620100 series [ ML620150 family ] of 16-bit low-power MCUs featuring superior noise resistance and high-temperature compatibility designed for home electronics and industrial equipment equipped with a motor, compressor, heater, or other noise-generating components.

The ML620150 family follows on the heels of the ML620500 series released in September of last year. In addition to LAPIS Semiconductor’s market-leading low power consumption design technology, this new series utilizes original noise resistance circuitry to achieve the highest level of performance in IEC61000-4-2 noise testing. And the microcontrollers themselves are highly resistant to noise, eliminating the need for additional noise countermeasures.

They also feature a wide operating temperature range, from -40 to +105 degrees C, making them suitable for use even in high temperature environments. In addition, 4-channel 16-bit pwm output enables control of IGBTs, providing compatibility with rice cookers, bread machines, induction heaters, and other high power applications.

A large number of consumer electronics devices and industrial equipment use motors, compressors, heaters, and other parts that generate noise. And some home electronics in particular work using the same power supply line in the kitchen, where countermeasures against power supply noise such as a system level shield are required. Also, many appliances and industrial equipment are exposed to high temperature environments due to the heat generated by motors and heaters, and therefore require stable operation at high temperatures.

At the same time, although 8-bit MCUs have been widely adopted in consumer electronics, the need to provide greater comfort and convenience is driving automation, greater functionality, more accurate sensors, and higher MCU performance, leading to a shift towards 16-bit microcontrollers. To meet these needs for high noise tolerance, high temperature compatibility, and greater performance, LAPIS Semiconductor offers a total of nine 16-bit low power microcontroller products in 3 different memory capacities and 3 package types.
