Product Overview
The MSP430G2553 is a Texas Instruments ultra-low-power mixed-signal microcontroller built around the 16-bit RISC MSP430 CPU. It supports a 1.8 to 3.6 V operating range, 230 uA active-mode current at 1 MHz and 2.2 V, 0.5 uA standby current, and 0.1 uA off-mode current with RAM retention. Five low-power modes and a standby-to-active wake-up time of less than 1 us support duty-cycled embedded designs.
Device resources include 16 KB flash, 512 B RAM, two Timer_A3 modules, and three capture/compare registers per 16-bit Timer_A. Analog functions include a 10-bit ADC rated at 200 ksps with 8 channels, internal reference, sample-and-hold, and autoscan, plus an 8-channel Comparator_A+.
The device is offered in 20-pin TSSOP, 28-pin TSSOP, 20-pin PDIP, and 32-pin QFN packages. I/O availability is 16 pins on 20-pin variants and 24 pins on 28-TSSOP and 32-QFN variants, with capacitive-touch support up to 24 pins. Serial onboard programming, Spy-Bi-Wire debug, and USCI_A0/USCI_B0 interfaces support development and assembly workflows.
