Product details
Overview
MSP430G2402IPW14R from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller in 14-pin TSSOP package, featuring 8 KB Flash, 256 B RAM, one 16-bit Timer_A with three capture/compare registers, Universal Serial Interface (USI) for SPI/I²C, and up to 16 capacitive-touch enabled I/O pins. It operates from 1.8 V to 3.6 V and targets battery-powered sensor nodes and portable instrumentation.
For engineers reviewing the MSP430G2402IPW14R datasheet, MSP430G2402IPW14R pinout, MSP430G2402IPW14R application, or MSP430G2402IPW14R equivalent, key selection criteria include its 8 KB Flash capacity, USI-based serial interface support, 16-pin-compatible TSSOP footprint, and verified low-power operation down to 0.1 µA in off mode with RAM retention.
Technical Context
The MSP430G2402IPW14R implements a 16-bit RISC CPU with 62.5-ns instruction cycle time and seven addressing modes, integrated with constant generators for optimized code efficiency. Its basic clock module delivers ACLK, SMCLK, and MCLK from internal DCO (calibrated at 1/8/12/16 MHz), LF oscillator, or external 32-kHz crystal.
It supports five software-selectable low-power modes - including LPM4 with 0.1 µA consumption - and features Spy-Bi-Wire on-chip emulation, brownout detection, and programmable security fuse. Unlike MSP430G2x32 variants, it excludes ADC10 functionality per Table 1 and functional block diagrams.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430G2553IPW20R | 20-pin TSSOP; includes 10-bit ADC10 (8-channel), 16 KB Flash, 512 B RAM; same USI and Timer_A peripherals | Required where analog signal acquisition (e.g., thermistor, potentiometer) is needed alongside digital control | Select when ADC functionality is mandatory and PCB layout allows 20-pin footprint |
| MSP430FR2111IPW16R | Ferroelectric RAM (FRAM) instead of Flash; 1 KB FRAM, 128 B RAM; lower active current (112 µA/MHz); no ADC | Better suited for frequent write-intensive logging or firmware updates due to FRAM endurance and speed | Prefer for high-cycle data logging or where Flash write endurance is insufficient; same 16-pin TSSOP footprint |
Compared with MSP430G2402IPW14R, the MSP430G2553IPW20R adds essential ADC capability at the cost of larger package and higher pin count, while the MSP430FR2111IPW16R trades Flash for FRAM's write speed and endurance - both require PCB redesign but offer distinct value in analog or high-write scenarios.

FAQ
Does MSP430G2402IPW14R include an analog-to-digital converter (ADC)?
No, MSP430G2402IPW14R does not include ADC10 functionality. Per Table 1 and functional block diagrams in SLAS723H, ADC10 is exclusive to MSP430G2x32 series devices (e.g., MSP430G2432). The MSP430G2402IPW14R belongs to the G2x02 series and provides only digital I/O, USI, Timer_A, and clock system - no analog input channels or reference voltages are implemented.
What is the maximum operating frequency of MSP430G2402IPW14R?
The MSP430G2402IPW14R supports internal DCO frequencies up to 16 MHz, as confirmed by calibration data in information memory segment A and Table 10 of SLAS723H. This allows full-speed execution of 16-bit instructions at 62.5-ns cycle time, with stable operation across 1.8–3.6 V supply range and ambient temperatures from –40°C to 85°C.
Can MSP430G2402IPW14R be programmed using standard JTAG?
MSP430G2402IPW14R uses Spy-Bi-Wire (SBW), a two-wire subset of JTAG, not full 4-wire JTAG. Pins RST/NMI/SBWTDIO (Pin 10) and TEST/SBWTCK (Pin 11) constitute the SBW interface. Standard JTAG adapters require SBW mode configuration; TI's MSP-FET and compatible debuggers natively support SBW for programming and real-time debugging of MSP430G2402IPW14R.
How many I/O pins support capacitive-touch sensing on MSP430G2402IPW14R?
All 16 I/O pins across Ports P1 and P2 support capacitive-touch sensing via the integrated pin-oscillator feature, as stated in the FEATURES section of SLAS723H. On the 14-pin TSSOP package, P1.0–P1.7 and P2.0–P2.5 are accessible (14 total), with P2.6 and P2.7 multiplexed with XIN/XOUT - all are individually configurable for touch using P1SEL/P2SEL and appropriate timer setup.
Is MSP430G2402IPW14R RoHS compliant and halogen-free?
Yes, MSP430G2402IPW14R is RoHS compliant and halogen-free per Texas Instruments' official product change notices and packaging documentation. The PW14 package meets JEDEC standards and carries TI's standard green marking; full compliance details are available in TI's Quality & Environmental Information portal under part number MSP430G2402IPW14R.
