Nuvoton - M2351SFSIAAP microcontroller

The M2351SFSIAAP microcontroller series is powered by Arm® Cortex®-M23 core with TrustZone® for Armv8-M architecture, having multi-chip-package (MCP) with M2351 Series and Winbond’s W77F Secure Flash. With the use of Winbond’s Secure Flash solution, M2351SFSIAAP can well protect code and data of a microcontroller from reducing vulnerability exposures. M2351 series offers a more enhanced software-level security for robust security and greater power efficiency. The low-power M2351 series microcontroller operates at up to 64 MHz frequency, with up to 512 Kbytes embedded Flash memory in dual bank mode, supporting secure OTA (Over-The-Air) firmware update and up to 96 Kbytes embedded SRAM. Furthermore, the M2351 series also provides high-performance connectivity peripheral interfaces such as UART, SPI, I²C, GPIOs, USB and ISO 7816-3 for a smart card reader. Its secure and efficient power management features strengthen the innovation of IoT security.  For compiler selection, M2351 Series supports the development on Arm® Keil MDK, IAR Embedded Workbench for Arm® and GCC. Furthermore, the Keil MDK Nuvoton Edition for M2351 series is free to use. For supporting tools, M2351 Series offers helpful tools to aid the project progress. For example, the TrustZone Template Generator could assist the security state planning and the secure firmware building; the CryptoTool could support the cryptographic requirements of M2351 series, including key generation, key exchange, signature, encryption and decryption.
