STMicroelectronics ST7FMC2N6B6

INTRODUCTION

The ST7MCx device is member of the ST7 microcontroller family designed for mid-range applications with a Motor Control dedicated peripheral.
All devices are based on a common industry-standard 8-bit core, featuring an enhanced instruction set and are available with FLASH, ROM or FASTROM program memory.
Under software control, all devices can be placed in WAIT, SLOW, ACTIVE-HALT or HALT mode, reducing power consumption when the application is in idle or stand-by state.
