Stretch application efficiency with optimized power for performance in the S3 Series. Handle data-intensive operations with minimal CPU clock cycles and a built-in Floating -Point Unit for data security with features such as Advanced Encryption Standard (AES), True Random Number Generator (TRNG), and Memory Protection Unit (MPU).
The MCU Groups within the S3 Series span flash memory sizes from 256KB to 1MB, SRAM from 32KB to 192KB, and vary in connectivity and peripherals.
Optimal combination of low power and high performance in the smallest device packages within the S3 MCU series, including 256KB of flash memory and 32KB SRAM. Features include a segment LCD controller, 14-bit A/D Converter, 12-bit D/A Converter, Capacitive Touch Sensing Unit, USB 2.0 Full-Speed, and a temperature sensor, in addition to safety and security.
Scale up to the S3A3 Group and get 512KB of flash memory, 96KB SRAM, and, with larger device package options, access more GPIO pins, connectivity options like the lrDA interface, and analog peripherals such as High-Speed Comparators.
Develop further complex applications with 1MB of flash memory, 192KB SRAM, an additional 12-bit D/A Converter, and many more 32-Bit and 16-Bit General PWM timers and serial communications interfaces, Secure Package in addition to most S3A3 features.
