M2351ZIAAE

The M2351ZIAAE microcontroller series is powered by Arm® Cortex®-M23 core with TrustZone® for Armv8-M architecture, which elevates the traditional firmware security to a new level of robust software security.

The low-power M2351 series microcontroller operates at up to 64 MHz frequency, with up to 512 KB embedded Flash memory in dual bank mode, supporting secure OTA ( Over-The-Air ) firmware update and up to 96 KB 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.
