Product details
Overview
MSP430G2302IPW1REP from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller with 1 kB flash, 256 B RAM, 10 I/O pins, integrated Timer_A (TA3), USI (SPI/I²C), and ADC10 (2-channel). It operates from 1.8 V to 3.6 V and targets radiation-tolerant sensor systems in defense, aerospace, and medical applications requiring extended temperature operation (–40°C to 85°C) and long-life reliability.
For engineers reviewing the MSP430G2302IPW1REP datasheet, MSP430G2302IPW1REP pinout, MSP430G2302IPW1REP application, or MSP430G2302IPW1REP equivalent, this page delivers verified technical context, exact pin functions for TSSOP-14, low-power mode timing behavior, real-world use cases in analog-sensing edge nodes, and two validated alternative MCUs with documented functional and packaging differences.
Technical Context
The MSP430G2302IPW1REP implements a 16-bit RISC CPU with constant generators and seven addressing modes, enabling single-cycle register operations and high code efficiency. Its clock system integrates a digitally controlled oscillator (DCO) calibrated at 1/8/12/16 MHz, plus internal LF oscillator and external 32-kHz crystal support - all selectable via BCSCTL registers.
It features a single 16-bit Timer_A (TA3) with three capture/compare registers, universal serial interface (USI) supporting hardware SPI and I²C, and a 10-bit ADC10 with two input channels (A0–A1), internal reference, and programmable conversion clock. All peripherals are memory-mapped and accessible via standard instructions without special opcodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | 16-bit RISC CPU with 16 general-purpose registers and constant generators; enables efficient C code execution and deterministic interrupt latency. |
| Flash / RAM | 1 kB flash (512-byte segments) + 256 B RAM; supports in-system programming via Spy-Bi-Wire and on-chip security fuse. |
| Supply Range | 1.8 V to 3.6 V during program execution; minimum 2.2 V required for flash programming - constrains power supply design in battery-powered systems. |
| Ultra-Low Power | 220 µA active @ 1 MHz/2.2 V; 0.5 µA standby; 0.1 µA off-mode with RAM retention - enables multi-year operation on coin-cell batteries. |
| Timer & Interface | 1× Timer_A3 (3 CC registers); USI supporting SPI master/slave and I²C master - eliminates need for external protocol ICs in sensor node designs. |
| ADC & I/O | ADC10 with 2 analog inputs (A0, A1), internal reference, and programmable clock; 10 GPIO pins (P1.0–P1.7, P2.6–P2.7) with individually configurable pullup/down and interrupt edges. |
| Package & Temp | 14-pin TSSOP (PW package); qualified for –40°C to 85°C extended temperature range with controlled baseline and product traceability for defense/aerospace use. |
Pinout & Package
Package: 14-pin Thin Shrink Small Outline Package (TSSOP-PW), JEDEC MO-153 compliant, 5.0 mm × 4.4 mm footprint, 0.65 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| DVCC (Pin 1) | Power supply input | Primary digital supply rail; must be decoupled locally with 100 nF ceramic capacitor to DVSS. |
| RST/NMI/SBWTDIO (Pin 10) | Reset / NMI input / Spy-Bi-Wire data I/O | Active-low reset; dual-function pin for debugging and programming - requires external pullup for reliable startup. |
| TEST/SBWTCK (Pin 11) | Test mode select / Spy-Bi-Wire clock | Enables JTAG/Spy-Bi-Wire interface; tied high during normal operation; pulsed low to enter test mode. |
| XIN/P2.6/TA0.1 (Pin 13) | Clock input / GPIO / Timer compare output | Accepts 32-kHz crystal or external clock; also serves as TA0.1 compare output - shared function requires careful pinmux configuration. |
| XOUT/P2.7 (Pin 12) | Clock output / GPIO | Crystal oscillator output; can be used as general-purpose I/O when crystal not used - internal driver remains enabled post-reset unless cleared. |
| DVSS (Pin 14) | Ground reference | Digital ground return; must be connected to system ground plane with low-inductance path to minimize noise coupling into ADC/timers. |
Key Features
| Feature | Design Value |
|---|---|
| Five software-selectable low-power modes | LPM0–LPM4 with sub-µA standby and 0.1 µA RAM-retention off-mode - enables rapid wake-up (<1 µs) and energy budgeting for duty-cycled sensing. |
| On-chip emulation logic | Spy-Bi-Wire interface using only RST/NMI and TEST pins - reduces debug footprint vs. full 4-wire JTAG and avoids dedicated debug headers. |
| Built-in brownout detector | Monitors DVCC and asserts reset if voltage drops below threshold - prevents erratic code execution during battery sag or power ramp-up. |
| Programmable code protection | Security fuse disables flash readback and JTAG access after programming - meets basic IP protection requirements for deployed firmware. |
| Calibrated DCO frequencies | Factory-trimmed DCO settings stored in info memory (segment A) for 1/8/12/16 MHz - eliminates need for external crystal in cost-sensitive timing applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power mixed-signal microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430G2402IPW1REP | 2 kB flash, 256 B RAM, same 14-TSSOP package, identical peripherals except adds 2-channel comparator. | Required when firmware size exceeds 1 kB or analog window-compare functionality is needed for threshold triggering. | Select when additional code space or comparator-based event detection is required; pin-compatible and drop-in replaceable. |
| MSP430FR2311IPW1R | Ferroelectric RAM (640 B FRAM), 3.75 kB FRAM, no flash, 14-TSSOP, same USI/Timer_A/ADC10 but lacks security fuse and EP qualification. | Preferred for high-write-cycle logging or instant-on operation where FRAM endurance >10¹⁴ cycles matters more than radiation tolerance. | Choose for industrial IoT with frequent data writes; not suitable for defense/aerospace due to lack of EP qualification and traceability. |
Compared with MSP430G2302IPW1REP, MSP430G2402IPW1REP offers direct pin- and code-compatible upgrade path with added flash and comparator, while MSP430FR2311IPW1R trades EP reliability and security for FRAM endurance and zero-write-delay - making it unsuitable for mission-critical defense use but advantageous in high-cycle industrial logging.

FAQ
What is the maximum operating frequency of the MSP430G2302IPW1REP?
The MSP430G2302IPW1REP supports a maximum MCLK frequency of 16 MHz when VCC ≥ 3.3 V and duty cycle is 50% ± 10%. At lower supply voltages, the maximum frequency is reduced: 12 MHz at 2.7 V and 6 MHz at 1.8 V. This is enforced by the DCO calibration data stored in information memory segment A, and the device will not reliably execute code above these limits under specified conditions.
Does the MSP430G2302IPW1REP include an ADC, and how many input channels does it support?
Yes, the MSP430G2302IPW1REP integrates a 10-bit successive-approximation ADC10 module with two analog input channels: A0 (P1.0) and A1 (P1.1). It supports internal reference (1.5 V or 2.5 V), programmable conversion clock, and sample-and-hold - sufficient for basic sensor interfacing but not for multi-channel simultaneous sampling.
Is the MSP430G2302IPW1REP pin-compatible with other devices in the MSP430G2xx family?
The MSP430G2302IPW1REP in 14-pin TSSOP is pin-compatible with MSP430G2402IPW1REP and MSP430G2553IPW1REP in the same package, sharing identical pin functions for DVCC, DVSS, RST/NMI, TEST, XIN/XOUT, and P1.x I/O. However, peripheral enable bits and register mappings differ - firmware porting requires validation of Timer_A, USI, and ADC10 initialization sequences.
What debug interface does the MSP430G2302IPW1REP support, and what pins are required?
The MSP430G2302IPW1REP supports Spy-Bi-Wire (SBW) debugging using only two pins: RST/NMI/SBWTDIO (Pin 10) and TEST/SBWTCK (Pin 11). This 2-wire interface replaces full 4-wire JTAG, reducing PCB routing complexity and enabling in-system programming without dedicated debug headers - critical for space-constrained embedded designs.
What qualifies the MSP430G2302IPW1REP for defense and aerospace applications?
The MSP430G2302IPW1REP is qualified as an Enhanced Product (EP) device: it features controlled baseline manufacturing (single fab/assembly/test site), extended –40°C to 85°C temperature range, product traceability, extended lifecycle support, and compliance with defense-grade documentation standards (e.g., V62/12623-01XE). These attributes meet MIL-PRF-38535 Class V requirements for high-reliability deployment.
