Product Portfolio

Two complementary semiconductor lines for embedded systems — microcontrollers for control, non-volatile memory for storage.

Microcontrollers

Mesilicon MCU Series

8-bit 1T 8051 and ARM Cortex-M family (M0, M0+, M3) for consumer electronics, home appliances, industrial control, IoT nodes and motor control. Designed for cost-effective mass production with robust ESD and wide 2.0–5.5 V operation.
