The 28-TSSOP package (4.4 mm body width) fits space-constrained PCBs in industrial sensors, portable instruments, and automotive cabin modules. At 16 MHz, the MSP430G2533 executes most single-cycle instructions, giving it a MIPS rating roughly equal to the clock speed. That is enough for reading a sensor via I2C or SPI at 100 kHz, updating a PWM output at 10 kHz, and running a simple control PID loop in the remaining cycles. ## 16 KB Flash and 512 B RAM — sizing the firmware budget The 16 KB Flash (16K x 8) is the program storage. A typical sensor node firmware with ADC sampling, UART logging, and I2C communication fits in about 6–10 KB, leaving headroom for field-upgradeable bootloader code. The 512 bytes of RAM (512 x 8) is the tight constraint: it holds stack, global variables, and small buffers. A 256-byte UART receive buffer plus a 128-byte sensor data structure uses most of it, so any large lookup table or double-buffered DMA transfer needs to live in Flash and be copied to RAM only when needed. That means it is still in volume production, no last-time-buy notice has been issued, and it remains a valid choice for new product introductions.","metaTitle":"TI MSP430G2533IPW28 16-Bit MCU, 16 MHz, 16 KB Flash","metaDescription":"Texas Instruments MSP430G2533IPW28 16-bit MCU, 16 MHz, 16 KB Flash, 512 B RAM, 8-ch 10-bit ADC, I2C/SPI/UART, -40 to 85°C, 28-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","RAM Size":"512 x 8","Core Size":"16-Bit","Packaging":"Tube","EEPROM Size":"-","Part Status":"Active","Peripherals":"Brown-out Detect/Reset, PWM, WDT","Connectivity":"I2C, IrDA, LINbus, SCI, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"24","Core Processor":"MSP430 CPU16","Package / Case":"28-TSSOP (0.173\\\", 4.40mm Width)","Data Converters":"A/D 8x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430G2533","Program Memory Size":"16KB (16K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"28-TSSOP","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.3600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/aa1021d14ccf54bbadb16cd01958dd1f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430G2533IPW28/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to MSP430G2533IPW28 in the MSP430G2xx family?","answer":"Within the same 28-TSSOP footprint, the MSP430G2553 offers double the Flash (16 KB vs. 16 KB — actually the G2553 has 16 KB as well, but with more RAM at 512 B vs. 512 B — the key difference is the G2553 includes a hardware multiplier and a second USCI module for simultaneous I2C and SPI.
