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.
Obsolete — sourcing through independent distribution
The MSP430FR6889IPZR carries an obsolete lifecycle status per the manufacturer. For BOM lines that require this exact part, procurement must rely on surplus inventory or broker channels. 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.
