Stretch application efficiency with optimized power for performance in the S3 Series. Handle data-intensive operations with minimal CPU clock cycles with a built-in Floating-Point Unit, and ensure data security with features such as AES, a True Random Number Generator, and a Memory Protection Unit. Build interactive displays using the segment LCD controller with capacitive touch interface for HMI applications.
The MCU Groups within the S3 Series span flash memory sizes from 256 KB to 1 MB, SRAM from 32 KB to 192 KB, 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 General PWM timers and serial communications interfaces, in addition to the S3A3 features.
