It carries 2 KB of program flash and 256 bytes of RAM — enough memory for small sensor-processing loops, simple control logic, or a single-protocol communication stack, but tight for a full RTOS or multi-protocol gateway. The 20-pin DIP package (0.300-inch width) is through-hole mounted, which makes it breadboard-friendly and easy to hand-solder in prototyping or low-volume production, but it occupies more board area than a surface-mount QFN or TSSOP alternative. ## Peripheral set and connectivity for sensor and actuator interfaces Sixteen general-purpose I/O pins are available, along with an 8-channel 10-bit analog-to-digital converter — enough to read several analog sensors (thermistors, potentiometers, current shunts) without an external multiplexer. The ADC resolution is 10 bits, giving 1024 steps across the reference voltage. Serial connectivity covers I²C, SPI, and UART/USART, plus IrDA and LINbus — the I²C and SPI buses handle common sensor modules (temperature, humidity, accelerometer), while the UART talks to a host controller or a Bluetooth module. The LINbus support is useful for automotive body-control nodes. The brown-out reset holds the MCU in reset until the supply rail is stable — critical for battery-powered or energy-harvesting designs where the voltage can sag during startup. The watchdog timer guards against firmware lock-ups in unattended operation. The 20-PDIP package has a seated height of about 5 mm above the board — the plastic body is standard DIP profile, no special handling needed.","metaTitle":"Texas Instruments MSP430G2233IN20 MCU, 16 MHz, 2 KB Flash","metaDescription":"MSP430G2233IN20 16-bit MCU from TI's MSP430G2xx series: 16 MHz CPU, 2 KB flash, 256 B RAM, 16 I/O, 8-channel 10-bit ADC, I²C/SPI/UART.","metaKeywords":null},"attributes":{"series":"MSP430G2xx","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"16MHz","Series":"MSP430G2xx","Package":"Tube","RAM Size":"256 x 8","Core Size":"16-Bit","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, PWM, WDT","Connectivity":"I²C, IrDA, LINbus, SCI, SPI, UART/USART","Mounting Type":"Through Hole","Number of I/O":"16","Core Processor":"MSP430 CPU16","Package / Case":"20-DIP (0.300\\\", 7.62mm)","Product Status":"Active","Data Converters":"A/D 8x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430G2233","Program Memory Size":"2KB (2K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"20-PDIP","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.7500","priceTiers":[{"qty":1,"price":"$2.75000","currency":"USD"},{"qty":10,"price":"$2.47400","currency":"USD"},{"qty":25,"price":"$2.33400","currency":"USD"},{"qty":100,"price":"$1.98860","currency":"USD"},{"qty":250,"price":"$1.86720","currency":"USD"},{"qty":500,"price":"$1.63380","currency":"USD"},{"qty":1000,"price":"$1.35372","currency":"USD"},{"qty":2500,"price":"$1.26036","currency":"USD"},{"qty":5000,"price":"$1.21368","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/aa1021d14ccf54bbadb16cd01958dd1f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430G2233IN20/alternatives.json"},"ai":{"faq":[{"question":"What is the MSP430G2233IN20's clock speed and memory size?","answer":"The core runs at 16 MHz with 2 KB of program flash and 256 bytes of RAM.
