The 16.384 MHz clock is a deliberate choice: it is a power-of-two multiple of the common 32.768 kHz watch crystal, so you can generate precise baud rates and timer intervals for metering or data-acquisition timing chains without fractional-N PLL jitter. ## Temperature grade and field-fit for industrial environments No commercial-grade derating worry when the enclosure hits 85°C on a summer afternoon. ## Package and footprint — what you need for the board","metaTitle":"TI MSP430I2021TPWR 16-bit MCU, 16.384 MHz, 32 KB Flash","metaDescription":"Texas Instruments MSP430I2021TPWR 16-bit MCU with 16.384 MHz CPU, 32 KB Flash, 2 KB RAM, dual 24-bit sigma-delta ADC, I²C/SPI/UART, -40°C to 105°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":"16.384Mhz","Series":"MSP430I2xx","Package":"Tape & Reel (TR)","RAM Size":"2K x 8","Core Size":"16-Bit","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, PWM, WDT","Connectivity":"I²C, IrDA, SCI, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"12","Core Processor":"MSP430 CPU16","Package / Case":"28-TSSOP (0.173\\\", 4.40mm Width)","Product Status":"Active","Data Converters":"A/D 2x24b Sigma-Delta","Oscillator Type":"External","lifecycle_stage":"eol_hot","Base Product Number":"MSP430I2021","Program Memory Size":"32KB (32K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~105°C(TA)","Supplier Device Package":"28-TSSOP","Voltage - Supply (Vcc/Vdd)":"2.2V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.7620","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/930bb8693ea1d814311da91a1434267f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430I2021TPWR/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to MSP430I2021TPWR?","answer":"Within the MSP430I2xx series, other members with the same 28-TSSOP footprint and dual 24-bit ADC block are pin-compatible across Flash and RAM density options.
