Uniquely suited for control applications that require low power operation modes and fast wake-up times, the S128 MCU Group has 256 KB of flash memory and 24 KB of SRAM. It includes a Memory Protection Unit (MPU) for additional safety and security, a Digital Addressable Lighting Interface (DALI), and a smart mix of analog and digital peripherals. 

Industrial Flow Measurement

 

Industrial Flow Measurement

On-chip operational amplifiers, High-Speed and Low-Speed Analog Comparators, and 14-bit A/D Converters enabling signal conditioning and precision analog measurement, make S128 Group MCUs ideal for industrial flow measurement applications. The MCUs support self-test of critical operations and have SRAM Error Correction Code (ECC).
