The 2K x 8 RAM and 52 general-purpose I/O lines suit it for metering, sensing, and control panels where low power and frequent data logging are the norm. An internal oscillator keeps the BOM lean, while the 8-channel 10-bit ADC handles analog inputs without an external converter. ## Supply voltage and temperature — design-in constraints The 56-TSSOP package has a 0.240\" body width and 6.10 mm body length. ## Peripherals and connectivity — what is on-chip On-chip peripherals include a brown-out detect/reset, power-on reset, PWM, and watchdog timer — the usual set for a standalone controller that must survive power glitches. For serial communication there are I²C, SPI, UART/USART, plus IrDA and SCI. The 52 I/O pins are more than enough for a keypad-and-LCD user interface or a sensor array with parallel data buses. ## Lifecycle — active and available There is no NRND flag, no last-time-buy notice, and no EOL announcement on this base number.","metaTitle":"Texas Instruments MSP430FR2033IG56R MCU, 16-bit, 16 MHz","metaDescription":"Texas Instruments MSP430FR2033IG56R 16-bit MCU with 16 MHz CPU, 15.5 KB FRAM, 2K x 8 RAM, 52 I/O, industrial temp -40°C to 85°C, 56-TSSOP.","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":"2K 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":"MSP430FR2033","Program Memory Size":"15.5KB (15.5K 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":"$1.4531","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ed20a79c2d2eb3c035989dda530723dc.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the operating frequency of MSP430FR2033IG56R?","answer":"The core runs at 16 MHz.
