16-bit MCU with 64KB FRAM and 16MHz core
The MSP430FR5987IRGCT: Its 64KB (64K x 8) program memory uses FRAM technology, which combines the non-volatility of flash with the write speed and endurance of RAM — no sector-erase penalty before writes, and data retention without a backup battery. With 2K x 8 of RAM, 48 I/O lines, and an internal oscillator, this part targets metering, sensing, and data-logging applications where low-power and frequent write cycles are the norm.
Peripheral set and connectivity for sensor fusion
Serial connectivity covers I²C, IrDA, SPI, and UART/USART, allowing the MCU to talk to common sensor, display, and radio modules over separate buses without a level translator in most cases. A 12-channel, 12-bit ADC handles analog sensor inputs; the 12 input channels multiplex into a single SAR core, so the sample rate per channel depends on the total scan sequence.
Supply range, temperature grade, and package
Operates from 1.8V to 3.6V supply, suiting both single-cell Li-ion and regulated 3.3V rails.
Active production and compliance status
It is ROHS3 compliant. Base product number MSP430FR5987; the IRGCT suffix indicates the specific 64-VQFN package and temperature grade.
