Active production — no last-time-buy risk
Texas Instruments lists the MSP430FR2032IG56 as an active product. No NRND, EOL, or last-time-buy notice is attached to this order code — the BOM line stays qualified for new builds without a redesign clock.
8.5 KB FRAM — non-volatile code and data in one unified memory
The 8.5 KB FRAM serves as both program memory and data storage, with no separate EEPROM needed. Write endurance is effectively unlimited compared to flash — useful for data-logging or parameter-update routines that cycle the same addresses every power cycle. The 1 KB SRAM provides scratchpad for stack and variables; the FRAM handles persistent state, so the part can power down between operations and wake with the last context intact.
16 MHz CPU16 core with 52 I/O in a 56-TSSOP
The 16-bit MSP430 CPU16 core runs at 16 MHz — the clock rate is modest by today's standards but the FRAM access time keeps the pipeline fed without wait states, so the effective throughput is closer to what a flash-based MCU delivers at a higher clock. The 52 I/O lines in a 56-TSSOP package give a high pin-to-package ratio; the 0.65 mm pitch on the TSSOP routes cleanly on a two-layer board for most sensor and control applications.
Serial connectivity and on-chip analog
The connectivity set covers I²C, SPI, UART/USART, plus IrDA and SCI — enough to talk to common sensor modules, serial displays, and wireless add-on modules without an external bridge. The 8-channel 10-bit ADC reads analog inputs; the internal oscillator frees a crystal pin for other use when the clock accuracy requirements are within the internal trim range.
Industrial temperature range and single-supply operation
Brown-out detect and POR handle power-up sequencing and supply dips.
ROHS3 and compliance documentation
Texas Instruments certifies the MSP430FR2032IG56 as ROHS3 compliant — no lead, mercury, cadmium, hexavalent chromium, PBB, or PBDE. The base product number is MSP430FR2032; the full order code carries the package and temperature suffix. Standard TI compliance documentation (RoHS, REACH, material declaration) is available per the product page.
