Product details
Overview
MSP430G2452IPW14 from Texas Instruments is an ultra-low-power 16-bit RISC mixed-signal microcontroller featuring 8 KB flash, 256 B RAM, a 10-bit 200-ksps ADC with internal reference and autoscan, USI supporting SPI/I²C, and Timer_A with three capture/compare registers. It operates from 1.8 V to 3.6 V and targets battery-powered sensor nodes and portable measurement systems.
For engineers reviewing the MSP430G2452IPW14 datasheet, MSP430G2452IPW14 pinout, MSP430G2452IPW14 application, or MSP430G2452IPW14 equivalent, key selection criteria include its 14-pin TSSOP package, integrated ADC10 channel count (8), standby current (0.5 µA), Spy-Bi-Wire debug interface, and capacitive-touch I/O capability on up to 16 pins.
Technical Context
The MSP430G2452IPW14 implements a 16-bit CPU with seven addressing modes and 51 instructions, paired with a digitally controlled oscillator (DCO) that achieves sub-1-µs wake-up from LPM4. Its clock system supports ACLK (LF crystal or internal VLO), SMCLK, and MCLK, with four factory-calibrated DCO frequencies up to 16 MHz.
It integrates a single 16-bit Timer_A (TA0) with three capture/compare registers, an 8-channel Comparator_A+, and a USI module configurable for synchronous SPI or I²C communication - all operating under five software-selectable low-power modes optimized for extended battery life in portable instrumentation.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430G2553IPW20 | 20-pin TSSOP, 16 KB flash, 512 B RAM, same peripherals plus UART, no ADC10 reference trimming calibration | Requires larger PCB area; supports UART-based host communication not available on MSP430G2452IPW14 | Select when additional flash/RAM or UART is required; not pin-compatible due to 20-pin vs. 14-pin layout |

FAQ
What is the maximum ADC sampling rate supported by the MSP430G2452IPW14?
The MSP430G2452IPW14 features a 10-bit successive approximation register (SAR) ADC capable of up to 200 ksamples per second (ksps). This maximum rate assumes optimal clock configuration (e.g., ADC10CLK sourced from SMCLK at ≥5 MHz) and minimal conversion setup overhead. Real-world throughput may vary based on reference selection, input channel count, and autoscan configuration - all documented in the SLAS722G datasheet for MSP430G2x52 devices.
Does the MSP430G2452IPW14 support hardware UART communication?
No, the MSP430G2452IPW14 does not include a dedicated UART peripheral. It features a Universal Serial Interface (USI) module that supports hardware SPI and I²C protocols only. UART functionality must be implemented in firmware using timer-generated bit-banging or by interfacing an external UART-to-SPI/I²C bridge IC. For native UART support, consider TI's MSP430G2553IPW20, which shares the same G2xx platform but adds USCI_A0 with UART capability.
How many I/O pins on the MSP430G2452IPW14 support capacitive touch sensing?
The MSP430G2452IPW14 supports capacitive touch sensing on up to 16 I/O pins - all eight pins of Port P1 and up to eight pins of Port P2 (P2.0–P2.5 plus P2.6 and P2.7). This capability relies on the integrated pin-oscillator feature, which is enabled per-pin via the PxIES and PxSEL registers. The 14-pin TSSOP package exposes eight P1 pins and two P2 pins (P2.0 and P2.1), limiting accessible touch-capable I/O to those ten pins in this specific封装.
What debug interface does the MSP430G2452IPW14 use, and what pins are required?
The MSP430G2452IPW14 uses the Spy-Bi-Wire (SBW) interface - a 2-wire subset of JTAG - for programming and debugging. It requires two dedicated pins: RST/NMI/SBWTDIO (Pin 10) for bidirectional data and TEST/SBWTCK (Pin 11) for clock. No external voltage is needed, and SBW operates at the device's DVCC voltage. This interface is supported by TI's MSP-FET and most third-party debuggers compatible with MSP430 SBW protocols.
Is the MSP430G2452IPW14 pin-compatible with other devices in the MSP430G2x52 family?
Yes, the MSP430G2452IPW14 is pin-compatible with other 14-pin TSSOP variants in the MSP430G2x52 family, including the MSP430G2352IPW14, MSP430G2252IPW14, and MSP430G2152IPW14. All share identical pin functions and electrical characteristics within the PW14 package. However, it is not pin-compatible with 20-pin (PW20) or QFN (RSA16) variants due to differing pin counts and assignments - especially for P2.x signals and AVCC/AVSS connections.
