128 KB FRAM — non-volatile memory with fast write endurance
Its program memory is 128 KB of FRAM — a non-volatile technology that combines the fast write speed and low power of SRAM with the data retention of Flash, without the write-cycle wear limits typical of EEPROM. This makes it well suited for applications that log data frequently or require field-reprogrammable firmware, such as industrial sensors, metering, and portable medical devices.
83 I/O and integrated peripherals
Connectivity options cover I²C, IrDA, SCI, SPI, and UART/USART, giving flexibility for interfacing with radios, ADCs, and serial displays.
Engineers evaluating new designs should consider current-production MSP430 FRAM variants in the same 100-LQFP footprint, though pin compatibility must be verified against the target application's peripheral requirements.
