A single-chip 8bit MCU, the MB95R203A featuring embedded FRAM (Ferroelectric Random Access Memory) from Fujitsu Semiconductor Europe protects high-speed write operations against power supply interruption. The FRAM offers another advantage: it writes fast that the MCU does not need to wait for the write operation to complete. It incorporates non-volatile FRAM, featuring enhanced access speeds and the ability to retain data in memory without power. The read/write endurance is specified as 1015 times, with data retention ensured for 10 years. The device incorporates 8Kbytes of user-accessible FRAM, which can be partitioned as either ROM or RAM. The ability to interchange data and work memory space makes it suitable for programming requirements. The device operates with power supplies ranging from 1.8 to 3.6V. It incorporates a complement of timers and communication functions, and A/D converters, UART, I2C, and 16 I/O ports. FRAM incorporates anti-tampering protection to enhance data security. FRAM does not require code for wear levelling, which is common in Flash and E2PROM given their limited endurance cycles.
