For a sensor node logging a few readings or a simple control loop, this memory budget is tight but workable — expect to fit a modest application without an RTOS. ## Peripheral set — what connects on-chip 32 general-purpose I/O lines give you enough pins for a keypad, LEDs, and a few external sensors. The 12-channel 10-bit ADC samples analog signals directly — no external converter needed for slow-varying inputs like temperature or potentiometer feedback. Connectivity options include I2C, SPI, and UART/USART, plus IrDA and LINbus for industrial or automotive bus interfaces. On-chip peripherals include a brown-out detect and reset, power-on reset, PWM, and a watchdog timer. These reduce external component count — the brown-out circuit holds the MCU in reset until the supply rail is stable, and the watchdog catches firmware hangs without an external supervisor IC. ## Package and board integration — 40-VQFN with exposed pad Housed in a 40-VQFN package measuring 6×6 mm, the MSP430F2234TRHAR has an exposed pad at the centre of the underside. The datasheet's recommended footprint includes a central thermal via array; skipping it can raise the junction temperature above the 105°C limit under continuous load. ## Temperature grade and environment The flash memory retains data across the full range, and the internal oscillator stays within a few percent over temperature — though for precision timing an external crystal is still recommended.","metaTitle":"MSP430F2234TRHAR 16-bit MCU, 16MHz, 8KB Flash, 40-VQFN","metaDescription":"Texas Instruments MSP430F2234TRHAR 16-bit MCU, 16MHz MSP430 CPU16, 8KB Flash, 512B RAM, 12-ch 10-bit ADC, -40 to 105°C, 40-VQFN.","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":"MSP430F2xx","RAM Size":"512 x 8","Core Size":"16-Bit","Packaging":"Tape & Reel (TR)","EEPROM Size":"-","Part Status":"Obsolete","Peripherals":"Brown-out Detect/Reset, POR, PWM, WDT","Connectivity":"I2C, IrDA, LINbus, SCI, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"32","Core Processor":"MSP430 CPU16","Package / Case":"40-VFQFN Exposed Pad","Data Converters":"A/D 12x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430F2234","Program Memory Size":"8KB (8K x 8 + 256B)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 105°C (TA)","Supplier Device Package":"40-VQFN (6x6)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.4663","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/e53eff369abc185c8b143f576da16742.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430F2234TRHAR/alternatives.json"},"ai":{"faq":[{"question":"How can I order the MSP430F2234TRHAR or check availability?","answer":"The MSP430F2234TRHAR is an active Texas Instruments microcontroller, sourced through independent distribution.
