S128
1. Overview
1. Overview
The S128 MCU integrates multiple series of software- and pin-compatible ARM®-based 32-bit MCUs that share a
common set of Renesas peripherals to facilitate design scalability and efficient platform-based product development.
Based on the energy-efficient ARM Cortex®-M0+ 32-bit core, this MCU is particularly suited for cost-sensitive and low-
power applications. The MCU in this series has the following features:
ï· Up to 256 KB code flash memory
ï· 24-KB SRAM
ï· Capacitive Touch Sensing Unit (CTSU)
ï· 14-bit A/D Converter (ADC14)
ï· 8-bit D/A Converter (DAC8)
ï· Security features.
