The 1 KB SRAM (1K x 8) handles stack and scratchpad data. This part targets applications where frequent data logging, low-energy writes, or unified memory simplifies the firmware architecture: smart meters, sensor nodes, portable instrumentation, and industrial controllers that log parameters without wearing out Flash. Eight channels of 10-bit ADC are on-chip, along with I²C, SPI, and UART serial interfaces. ## Industrial temperature rating and 52 I/O in a 56-TSSOP The 56-TSSOP package (6.10 mm body width) gives access to 52 general-purpose I/O lines — enough to drive a character LCD, read a keypad matrix, and manage a handful of sensors or relays without an I/O expander. Brown-out reset and power-on reset are integrated, so the supply supervisor on the board can be a simple RC filter rather than a dedicated reset IC. For dual-sourcing resilience, the MSP430FR2033 (same package, larger FRAM) is a drop-in hardware alternative if the BOM later needs more memory — the pinout and peripheral set are identical across the FR203x family.","metaTitle":"TI MSP430FR2032IG56R 16-bit MCU, 8.5KB FRAM, 16MHz, 56-TSSOP","metaDescription":"Texas Instruments MSP430FR2032IG56R 16-bit MCU with 8.5KB FRAM, 1KB SRAM, 52 I/O, 16MHz CPU, -40°C to 85°C, 1.8V-3.6V supply.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"16MHz","Series":"MSP430™ FRAM","Package":"Tape & Reel (TR)","RAM Size":"1K x 8","Core Size":"16-Bit","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, POR, PWM, WDT","Connectivity":"I²C, IrDA, SCI, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"52","Core Processor":"MSP430 CPU16","Package / Case":"56-TFSOP (0.240\\\", 6.10mm Width)","Product Status":"Active","Data Converters":"A/D 8x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430FR2032","Program Memory Size":"8.5KB (8.5K x 8)","Program Memory Type":"FRAM","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"56-TSSOP","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.0886","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/951d0819ec4c435acd66b746769a8533.pdf","sourceUrl":null},"ai":{"faq":[{"question":"How does MSP430FR2032IG56R compare to MSP430FR2033?","answer":"The MSP430FR2033 is the higher-density sibling in the same package and pinout: it doubles the FRAM to 16 KB versus 8.5 KB on the FR2032, and the SRAM to 2 KB versus 1 KB. Core, peripherals, ADC, serial interfaces, and operating range are identical.
