At 16 MHz the CPU16 can execute a single-cycle multiply in one clock, so a 10-bit ADC read and a UART byte transmit fit inside a 62.5 ns window. That is fast enough for 100 kHz sensor polling loops or a 20 kHz PWM update from the on-chip timer. ## 2 KB Flash, 256 B RAM — sizing the firmware envelope With 2 KB of Flash and 256 bytes of RAM, the firmware budget is tight. That is enough for a simple state machine with a few lookup tables, a UART command parser, and an I²C driver for a sensor. It will not hold a real-time operating system or a TCP/IP stack. Plan the code size before committing the BOM — the MSP430G2xx family includes pin-compatible parts with up to 8 KB Flash if the application grows. The brown-out detect resets the core cleanly when the battery sags below the operating threshold. ## 20-TSSOP package — board-fit notes The 20-TSSOP body is 4.4 mm wide with a 0.65 mm pitch — a compact footprint for space-constrained designs. It is a surface-mount package, so reflow soldering is standard. The supplier device package is 20-TSSOP; the package / case is 20-TSSOP (0.173\", 4.40 mm Width). No exposed thermal pad, so heat dissipation is through the leads — keep the ambient load within the 85°C ceiling.","metaTitle":"MSP430G2233IPW20R 16-bit MCU, 16 MHz, 2 KB Flash, 20-TSSOP","metaDescription":"Texas Instruments MSP430G2233IPW20R 16-bit MCU, 16 MHz core, 2 KB Flash, 256 B RAM, 8x10-bit ADC, I²C/SPI/UART, -40°C to 85°C, 20-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":"MSP430G2xx","Package":"Tape & Reel (TR); Cut Tape (CT)","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":"Surface Mount","Number of I/O":"16","Core Processor":"MSP430 CPU16","Package / Case":"20-TSSOP (0.173\\\", 4.40mm Width)","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-TSSOP","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.8148","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/aa1021d14ccf54bbadb16cd01958dd1f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430G2233IPW20R/alternatives.json"},"ai":{"faq":[{"question":"Is MSP430G2233IPW20R a direct replacement for MSP430G2233IPW20?","answer":"The base product number is the same (MSP430G2233), and the package is 20-TSSOP for both. The -IPW20R suffix indicates tape-and-reel packaging; the -IPW20 variant may ship in tube or tray. Electrically they are identical. Confirm the packaging preference for your assembly line before ordering."},{"question":"Can I use MSP430G2233IPW20R with 5V logic?","answer":"No. The I/O pins are not 5 V tolerant. Driving a 5 V logic signal into a pin will exceed the absolute maximum ratings. Use a level shifter or a 3.3 V bus."},{"question":"How to program MSP430G2233IPW20R?","answer":"Programming uses the Spy-Bi-Wire (SBW) two-wire JTAG interface, which is standard on all MSP430G2xx devices. A TI LaunchPad or a standalone programmer like the MSP-FET connects to the SBW pins. The internal oscillator is sufficient for programming; no external clock is needed."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MSP430G2233IPW20R","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MSP430G2233IPW20R when reusing this data.
