Texas Instruments MSP430G2202IPW14R

Overview

MSP430G2202IPW14R 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 support for up to 16 capacitive-touch 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 MSP430G2202IPW14R datasheet, MSP430G2202IPW14R pinout, MSP430G2202IPW14R application, or MSP430G2202IPW14R equivalent, key selection criteria include its 2 kB flash capacity, USI-based serial interface compatibility, 16-bit Timer_A configuration, ultra-low standby current (0.5 µA), and TSSOP-14 footprint suitability for space-constrained PCB layouts.

Technical Context

The MSP430G2202IPW14R implements a 16-bit RISC CPU with 62.5-ns instruction cycle time and five software-selectable low-power modes, including LPM4 with 0.1 µA off-mode current. Its clock system integrates a digitally controlled oscillator (DCO) calibrated to 1 MHz, 8 MHz, 12 MHz, and 16 MHz, plus internal LF and external 32-kHz crystal options.

It features two 8-bit digital I/O ports (P1 and P2), with P1 supporting edge-selectable interrupts and individually programmable pullup/pulldown resistors; P2 provides six general-purpose I/O pins in the 14-pin TSSOP variant. The USI module supports synchronous SPI and I²C protocols without dedicated hardware peripherals.

FAQ

Does MSP430G2202IPW14R include an analog-to-digital converter (ADC)?

No, the MSP430G2202IPW14R does not include an ADC module. It belongs to the MSP430G2x02 subfamily, which omits the ADC10 peripheral present in the MSP430G2x32 series (e.g., MSP430G2232IPW14). All ADC-related pins (e.g., A0–A7, VREF±) are reserved but nonfunctional on MSP430G2202IPW14R. For ADC capability, consider MSP430G2232IPW14 or other G2x32 variants.

What is the maximum operating frequency of MSP430G2202IPW14R?

The MSP430G2202IPW14R supports a maximum system clock frequency of 16 MHz via its digitally controlled oscillator (DCO), with factory-calibrated settings for 1 MHz, 8 MHz, 12 MHz, and 16 MHz. This DCO operates without external components and achieves stable startup in less than 1 µs, enabling fast wake-up from LPM3/LPM4 modes while maintaining ultra-low-power operation.

Can MSP430G2202IPW14R be programmed in-system without external hardware?

Yes, the MSP430G2202IPW14R supports in-system programming via its integrated Spy-Bi-Wire (SBW) interface using only two pins (RST/NMI/SBWTDIO and TEST/SBWTCK). No external programming voltage is required - standard 1.8–3.6 V supply powers the programming sequence. TI's MSP-FET and compatible debuggers enable full flash erase/write, security fuse configuration, and real-time debugging without removing the device from the PCB.

How many I/O pins are available on MSP430G2202IPW14R in the TSSOP-14 package?

The MSP430G2202IPW14R provides 10 usable digital I/O pins in the 14-pin TSSOP package: P1.0 through P1.7 (8 pins) and P2.6/P2.7 (2 pins). Pins P2.0–P2.5 are not bonded out in this package variant and are unavailable. All P1 pins support capacitive-touch sensing via individual pin-oscillator enable bits, and all I/Os feature programmable pullup/pulldown resistors.

Is MSP430G2202IPW14R pin-compatible with other devices in the MSP430G2xx family?

The MSP430G2202IPW14R shares the same 14-pin TSSOP (PW14) footprint and pin assignments with other G2xx devices in that package, including MSP430G2232IPW14 and MSP430G2102IPW14. However, functional pin mapping differs - for example, ADC-related functions on P1.3–P1.7 are inactive on MSP430G2202IPW14R. Direct replacement requires verification of peripheral usage and firmware compatibility.
