Product details
Overview
MSP430G2202IPW14 from Texas Instruments is an ultra-low-power 16-bit RISC mixed-signal microcontroller in 14-pin TSSOP package, featuring 2 kB flash, 256 B RAM, one 16-bit Timer_A with three capture/compare registers, Universal Serial Interface (USI) for SPI/I²C, and Spy-Bi-Wire debug interface - designed for battery-powered sensor nodes and touch-enabled control panels.
For engineers reviewing the MSP430G2202IPW14 datasheet, MSP430G2202IPW14 pinout, MSP430G2202IPW14 application, or MSP430G2202IPW14 equivalent, key selection criteria include its 1.8–3.6 V supply range, sub-1 µs wake-up from LPM4, 220 µA active current at 1 MHz/2.2 V, and absence of integrated ADC (unlike MSP430G2x32 variants).
Technical Context
The MSP430G2202IPW14 implements a 16-bit CPU with seven addressing modes and 51-instruction set, paired with a basic clock module supporting internal DCO (calibrated up to 16 MHz), LF oscillator, and external crystal input. It uses a single 16-bit Timer_A (TA0) with three CC registers for PWM, capture, and interval timing - no ADC10 or DMA support.
Power management includes five low-power modes (LPM0–LPM4); LPM4 draws only 0.1 µA with RAM retention. Debug is handled exclusively via Spy-Bi-Wire (SBW) using RST/NMI and TEST pins - JTAG is not supported on this variant.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | 16-bit RISC CPU with 16 general-purpose registers and constant generator; enables efficient C code execution and deterministic interrupt latency. |
| Flash / RAM | 2 kB flash memory (512-byte segments) and 256 B RAM; supports in-system programming via Spy-Bi-Wire without external voltage. |
| Supply Voltage | 1.8 V to 3.6 V operation; allows direct use with single-cell Li-ion, two-cell alkaline, or regulated 3.3 V rails. |
| Active Current | 220 µA at 1 MHz, 2.2 V - enables multi-year battery life in periodic-sensing applications like wireless sensor tags. |
| Wake-up Time | < 1 µs from LPM4 to active mode - critical for ultra-low-duty-cycle wake-on-event systems such as door/window sensors. |
| Timer Resource | One 16-bit Timer_A (TA0) with three capture/compare registers (TA0.0, TA0.1, TA0.2); supports PWM generation, input capture, and real-time clocking via ACLK. |
| Communication | Universal Serial Interface (USI) supporting hardware SPI and I²C protocols - reduces firmware overhead for interfacing with EEPROMs, sensors, or displays. |
Pinout & Package
14-pin TSSOP (PW14) package, 5.0 mm × 6.4 mm body, 0.65 mm pitch; thermally enhanced for compact PCB layouts in space-constrained industrial controls and wearables.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| DVCC (Pin 1) | Supply voltage input | Primary digital power rail; requires local 100 nF decoupling to DVSS for stable core operation. |
| P1.0/TA0CLK/ACLK/A0 (Pin 2) | Multi-function I/O | Configurable as Timer_A clock input, ACLK output, or general-purpose I/O - no ADC function (MSP430G2x02 lacks ADC10). |
| P1.1/TA0.0/A1 (Pin 3) | Capture/compare I/O | Timer_A channel 0 input/output; supports edge-triggered capture or PWM output - no analog input capability. |
| P1.2/TA0.1/A2 (Pin 4) | Capture/compare I/O | Timer_A channel 1 input/output; usable for dual-edge PWM or quadrature decoding with P1.1. |
| P1.3/ADC10CLK/A3 (Pin 5) | Reserved / NC | Pin name includes ADC10CLK but ADC10 is absent in MSP430G2x02 series - functions only as GPIO or TA0.2 clock source. |
| P1.4/TA0.2/SMCLK/A4 (Pin 6) | Capture/compare I/O | Timer_A channel 2 input/output; also outputs SMCLK for peripheral synchronization. |
| P1.5/TA0.0/SCLK/A5 (Pin 7) | USI clock I/O | Provides serial clock for USI in SPI mode (SCLK) or Timer_A compare output - no ADC function. |
| P1.6/TA0.1/SDO/SCL/A6 (Pin 8) | USI data/clock I/O | Serial data output (SPI) or I²C clock (SCL); dual-role pin requires careful mode configuration during initialization. |
| P1.7/SDI/SDA/A7 (Pin 9) | USI data I/O | Serial data input (SPI) or I²C data (SDA); supports bidirectional communication with minimal external components. |
| P2.0–P2.5 (Pins 10–13) | General-purpose I/O | Six dedicated GPIO pins with individually configurable pullup/pulldown resistors and interrupt-on-change capability. |
| RST/NMI/SBWTDIO (Pin 14) | Debug & reset I/O | Combined reset input, non-maskable interrupt, and Spy-Bi-Wire data I/O - requires 47 kΩ pullup for reliable reset assertion. |
| TEST/SBWTCK (Pin 15) | Debug clock input | Test mode select and Spy-Bi-Wire clock; must be driven high during programming to enable SBW interface. |
| XIN/P2.6/TA0.1 (Pin 16) | Oscillator input | Crystal oscillator input or general-purpose I/O; when used as XIN, requires external 32.768 kHz crystal between Pins 16 and 17. |
| XOUT/P2.7 (Pin 17) | Oscillator output | Crystal oscillator output or GPIO; must be left unconnected if external clock source is used instead of crystal. |
| DVSS (Pin 18) | Digital ground | Reference return path for DVCC; requires low-impedance connection to system ground plane. |

FAQ
Does MSP430G2202IPW14 include an analog-to-digital converter (ADC)?
No, MSP430G2202IPW14 does not include an ADC. It belongs to the MSP430G2x02 series, which omits the ADC10 module present in the G2x32 variants. All pins labeled with "A0" through "A7" in the datasheet are reserved for future compatibility and function solely as GPIO or timer/USI resources in MSP430G2202IPW14.
What debug interface does MSP430G2202IPW14 support?
MSP430G2202IPW14 supports only the Spy-Bi-Wire (SBW) interface using pins RST/NMI/SBWTDIO (Pin 14) and TEST/SBWTCK (Pin 15). It does not support full 4-wire JTAG. Programming and debugging require TI's MSP-FET or compatible SBW-capable tools - no external level shifters needed for 3.3 V systems.
Can MSP430G2202IPW14 drive an external 32.768 kHz crystal?
Yes, MSP430G2202IPW14 can drive a 32.768 kHz crystal connected between XIN/P2.6 (Pin 16) and XOUT/P2.7 (Pin 17). The basic clock module includes built-in load capacitance and startup circuitry; no external capacitors are required for standard watch crystals. This enables precise real-time clock (RTC) functionality using ACLK.
How many I/O pins does MSP430G2202IPW14 provide in the 14-pin TSSOP package?
MSP430G2202IPW14 provides 10 usable I/O pins: P1.0–P1.7 (8 pins) and P2.0–P2.5 (6 pins), though P2.6 and P2.7 are multiplexed with crystal oscillator functions. When XIN/XOUT are used for crystal, P2.6 and P2.7 are unavailable as GPIO; otherwise, they serve as general-purpose I/O - yielding up to 12 total I/O depending on clock configuration.
Is MSP430G2202IPW14 pin-compatible with other devices in the MSP430G2xx family?
MSP430G2202IPW14 shares the same 14-pin TSSOP (PW14) footprint with MSP430G2102IPW14, MSP430G2302IPW14, and MSP430G2402IPW14 - enabling drop-in replacement within the G2x02 series. However, it is not pin-compatible with G2x32 variants (e.g., MSP430G2232IPW14) due to differing ADC-related pin functions and register mappings.
