The device integrates 2K x 8 of RAM, an 8-channel 10-bit ADC, and serial interfaces including I²C, SPI, and UART. ## Why FRAM matters for the BOM FRAM combines the non-volatility of Flash with the write speed and low power of SRAM. For the MSP430FR2533IRHBT, this means the 15.5 KB program memory can be written byte-by-byte at full bus speed without erase cycles, making it ideal for frequent data logging, configuration updates, or over-the-air firmware patches. The 2K x 8 RAM handles stack and scratchpad variables. The 19 general-purpose I/O pins, plus the internal oscillator, reduce external component count—a brown-out detect and POR are on-chip, so the BOM can skip an external supervisor IC in many designs. ## Package and footprint Housed in a 32-VFQFN exposed-pad package (5x5 mm body), the MSP430FR2533IRHBT is a surface-mount device. The supplier device package is 32-VQFN (5x5).","metaTitle":"TI MSP430FR2533IRHBT 16-bit MCU, 16 MHz, 15.5 KB FRAM","metaDescription":"Texas Instruments MSP430FR2533IRHBT 16-bit MCU with 16 MHz CPU, 15.5 KB FRAM, 2 KB RAM, 19 I/O, -40°C to 85°C.","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); Cut Tape (CT)","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":"19","Core Processor":"MSP430 CPU16","Package / Case":"32-VFQFN Exposed Pad","Product Status":"Active","Data Converters":"A/D 8x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430FR2533","Program Memory Size":"15.5KB (15.5K x 8)","Program Memory Type":"FRAM","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"32-VQFN (5x5)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.6200","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/e93bf6c792e77b1433c19407d54c8edf.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the FRAM size of MSP430FR2533IRHBT?","answer":"The MSP430FR2533IRHBT has 15.5 KB of FRAM program memory, organized as 15.5K x 8 bits."},{"question":"What is the closest pin-compatible alternative to MSP430FR2533IRHBT?","answer":"Within the MSP430 FRAM family, devices sharing the same 32-VQFN (5x5) footprint and pinout—such as higher-density FRAM variants—are form-fit-function alternatives.
