MSP430G2553IPW20

MSP430G2553IPW20 is the Texas Instruments MSP430G2553 value-line microcontroller in a 20-pin TSSOP package — a 16 MHz 16-bit RISC core with 16 KB Flash and 512 B SRAM, a 1.8 V to 3.6 V supply, an 8-channel 10-bit 200-ksps ADC and USCI UART/SPI/I2C, over -40 to +85 °C (datasheet SLAS735J). TI lists the family ACTIVE: the 2011-era datasheet does not make this part obsolete, and it remains the code-compatible heart of countless LaunchPad-era designs. Active-mode current is 230 µA at 1 MHz and 2.2 V, with 0.5 µA standby. Selection advice: the reel code for this package is MSP430G2553IPW20R; the MSP430G2553IN20 PDIP code serves hand assembly and prototyping in the same memory configuration, while the 28-pin IPW28 and 32-pin QFN variants add I/O — match the full code to the footprint.
