Renesas' S3A1 MCU group of products provide up to 1 MB code Flash, 192 K SRAM with segment LCD controllers, capacitive touch unit, and a host of analog and security features to realize a variety of embedded systems and IoT designs. The S3A1 MCUs are feature, pin, and IP compatible with other Synergy MCU groups offering unparalleled scalability, and code reuse to accelerate hardware and software development. The S3A1 MCUs are available in many different memory densities and package/pin footprints. Renesas has achieved a revolutionary new level of abstraction in the design process, enabling the designer to start development at the application programming interface (API), thus reducing time to market, lowering total cost of ownership, and removing barriers to entry. Beneath that API layer sits a massive software platform which represents more than 200 man years of development work and over a million lines of code. And Renesas is prepared to support, qualify, and maintain the complete platform as a product, to their usual high standards of quality and reliability.

Getting started with the new S3A1 MCU group and SSP v1.4.0 is easy and inexpensive. The TB-S3A1 kit featuring 48 MHz Arm® Cortex®-M4 based MCU and pin headers can be utilized to connect to MCU pins and access various peripherals. The board features Pmod™ connectors to allow connection to a vast ecosystem of add-ons, and J-Link® on board for programming and debugging.
