To support the MCU family, the v.1.4.0 version update for the Synergy Software Package (SSP) ahs also been announced.
S3A1 MCUs feature many analogue and security features at a competitive price point. The MCUs are powered by an ARM Cortex-M4 processor with FPU operating at up to 48MHz. The processor is supported by 1MB Flash, a 192KB SRAM module, and security and encryption features (AES128/256, GHASH, RNG). A segment LCD controller, a capacitive touch-sensing unit, numerous connectivity options, a 14-bit A/D and a 12-bit A/D converter are also integrated. The maximum supply voltage is 5.5V.
To support MCU configuration, Renesas offers the TB-S3A1 Target Board Kit, which provides access to all pins and has standardised extension ports as well as pre-installed demo software.
The MCUs are available on Rutronik24.com in four packages (LQFP, QFN, 100LGA, 145LGA).
