MCU GROUP
Ideal for monitoring applications that may require ongoing feature upgrades for multiple services, the S3A1 MCU Group offers ample room for expansion and the optimal combination of low power and high performance, with an Arm® Cortex®-M4 CPU core running up to 48 MHz, 1 MB of flash memory, and 192 KB of SRAM. It includes an additional 12-bit D/A Converter as well as multiple 32-Bit General PWM timers and serial communications interfaces.
INDOOR OUTDOOR WEATHER STATION
Large on-chip SRAM and flash memory, as well as the capability to directly drive segment LCD glass panels and read capacitive touch buttons, make S3A1 Group MCUs a smart fit for applications such as a weather station panel. Rich audio input and output over a SSI interface, data logging to memory on a QSPI bus, and USB connectivity, offer new feature possibilities.
