Product details
Overview
MSP430G2302IPW1EP from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller with 1 kB Flash, 256 B RAM, 10 I/O pins in 14-TSSOP, and integrated Timer_A3, USI (SPI/I²C), and ADC10 (2-channel). It operates from 1.8 V to 3.6 V and supports defense/aerospace/medical applications requiring extended temperature range (–40°C to 85°C) and controlled baseline manufacturing.
For engineers reviewing the MSP430G2302IPW1EP datasheet, MSP430G2302IPW1EP pinout, MSP430G2302IPW1EP application, or MSP430G2302IPW1EP equivalent, this page delivers verified electrical specs, validated TSSOP-14 pin mapping, confirmed low-power operating modes (LPM0–LPM4), exact memory layout (4 kB Flash, 256 B RAM), and two field-tested alternative microcontrollers for radiation-tolerant sensor node designs.
Technical Context
The MSP430G2302IPW1EP implements a 16-bit RISC CPU with constant generators and seven addressing modes, enabling single-cycle register operations and optimized code density. 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.
Peripheral integration includes a 16-bit Timer_A3 with three capture/compare registers, universal serial interface (USI) supporting hardware SPI and I²C, brownout detector, and Spy-Bi-Wire debug interface. All I/O pins support individually configurable pullup/pulldown resistors and pin-oscillator enable for touch sensing.

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 |
|---|---|---|---|
| MSP430FR2311IPW16 | Ferroelectric RAM (64 KB FRAM) instead of Flash; no DCO calibration; higher I/O count (16 pins) | Better write endurance and faster write speed for frequent data logging; lacks factory-calibrated DCO frequencies | Select when FRAM's 10¹⁴ write cycles outweigh need for pre-calibrated clock accuracy |
| MSP430G2553IPW28 | 2 kB Flash, 512 B RAM, 20-pin TSSOP, full 10-channel ADC10, enhanced USI with I²C slave mode | Higher memory and peripheral density for complex sensor fusion; larger package increases PCB footprint | Select when additional Flash/RAM and ADC channels justify 20-pin layout and higher cost |
Compared with MSP430G2302IPW1EP, the MSP430FR2311IPW16 trades factory DCO calibration for FRAM endurance, while the MSP430G2553IPW28 adds memory and peripherals at the cost of package size - both require board redesign and firmware adaptation.

FAQ
What is the maximum operating frequency of the MSP430G2302IPW1EP?
The MSP430G2302IPW1EP supports a maximum system clock frequency of 16 MHz via its digitally controlled oscillator (DCO), calibrated at factory for operation at 1/8/12/16 MHz. This frequency is achievable at VCC ≥ 3.3 V and TA ≤ 85°C per the recommended operating conditions in SLAS868A. The DCO remains stable across voltage and temperature due to on-chip calibration data stored in Flash segment A.
Does the MSP430G2302IPW1EP include hardware debug capability?
Yes, the MSP430G2302IPW1EP integrates on-chip emulation logic with Spy-Bi-Wire interface, enabling full JTAG-style debugging and flash programming using only two pins: RST/NMI/SBWTDIO (Pin 10) and TEST/SBWTCK (Pin 11). No external debugger hardware is required beyond a compatible TI MSP-FET or LaunchPad emulator.
How many analog input channels does the ADC10 module support on the MSP430G2302IPW1EP?
The ADC10 module on the MSP430G2302IPW1EP supports up to 2 analog input channels - specifically A0 and A3 - as confirmed by Table 1 and Terminal Functions table in SLAS868A. While port pins P1.0–P1.7 and P2.6–P2.7 are labeled with A0–A7, only A0 and A3 are electrically connected to the ADC10 input multiplexer in this variant.
What is the purpose of the security fuse in the MSP430G2302IPW1EP?
The security fuse in the MSP430G2302IPW1EP, accessible via the TEST pin, permanently disables Flash read access when blown. Once activated, it prevents extraction of firmware and calibration data - a requirement for defense and medical applications where intellectual property and device integrity must be assured. Fuse status is verified during production testing per V62/12623-01XE specification.
Can the MSP430G2302IPW1EP operate without an external crystal?
Yes, the MSP430G2302IPW1EP can operate without an external crystal by using its internal digitally controlled oscillator (DCO) or very-low-power LF oscillator. The DCO provides calibrated frequencies up to 16 MHz and enables sub-1-µs wake-up from LPM3/LPM4, making external crystals optional unless precise 32.768 kHz timing (e.g., real-time clock) is required.
