Product details
Overview
MSP430G2352IPW14R from Texas Instruments is an ultra-low-power 16-bit RISC mixed-signal microcontroller in 14-pin TSSOP package, featuring 4 KB flash, 256 B RAM, 10-bit 200-ksps ADC with internal reference and autoscan, USI supporting SPI/I²C, one 16-bit Timer_A with three capture/compare registers, and integrated comparator. It targets battery-powered sensor nodes and portable measurement systems requiring sub-1-µs wake-up and <0.1 µA off-mode current.
For engineers reviewing the MSP430G2352IPW14R datasheet, MSP430G2352IPW14R pinout, MSP430G2352IPW14R application, or MSP430G2352IPW14R equivalent, key selection criteria include verified 10-bit ADC performance at 200 ksps, confirmed 14-pin TSSOP pin mapping with P1.x/P2.x I/O allocation, brownout detection with programmable threshold, Spy-Bi-Wire debug interface compatibility, and calibrated DCO operation across 1–16 MHz with factory-trimmed settings stored in info memory.
Technical Context
The MSP430G2352IPW14R implements a 16-bit RISC CPU with seven addressing modes and 51 instructions, executing register-to-register operations in one CPU cycle. Its clock system integrates a digitally controlled oscillator (DCO) with four factory-calibrated frequencies (1/8/12/16 MHz), LF oscillator, and 32-kHz crystal support - all selectable via BCSCTL1/2/3 and DCOCTL registers.
Peripherals are memory-mapped and accessible via full instruction set: ADC10 uses ADC10CTL0/1 and ADC10MEM for conversion control and result storage; USI operates in SPI or I²C mode using USICTL0/1 and USISR; Timer_A3 supports PWM, capture, and interval timing through TACCTLx and TAR registers; Comparator_A+ provides eight-channel analog comparison with CAOUT output and interrupt capability.
