Texas Instruments MSP430G2212IPW14

Overview

MSP430G2212IPW14 from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller in 14-pin TSSOP packaging, 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 an on-chip analog comparator. It operates from 1.8 V to 3.6 V and supports capacitive-touch I/O - ideal for battery-powered sensor nodes and portable instrumentation.

For engineers reviewing the MSP430G2212IPW14 datasheet, MSP430G2212IPW14 pinout, MSP430G2212IPW14 application, or MSP430G2212IPW14 equivalent, key selection criteria include its 14-pin TSSOP footprint, absence of ADC10 (distinguishing it from G2x52 variants), low-power operating modes (LPM0–LPM4), and Spy-Bi-Wire debug interface compatibility.

Technical Context

The MSP430G2212IPW14 implements a 16-bit RISC CPU with 62.5-ns instruction cycle time, constant generators, and seven addressing modes. Its clock system integrates a digitally controlled oscillator (DCO) calibrated at 1/8/12/16 MHz, plus LF oscillator and external crystal support - enabling sub-1-µs wake-up from standby mode.

Peripheral integration includes USI supporting master/slave SPI and I²C protocols, Comparator_A+ with eight input channels, and two 8-bit I/O ports (P1 and P2) with individually configurable pullup/pulldown resistors, interrupt edge select, and capacitive-touch enable bits - all managed via memory-mapped registers accessible by all CPU instructions.

FAQ

Does the MSP430G2212IPW14 include an ADC10 module?

No, the MSP430G2212IPW14 does not include the ADC10 analog-to-digital converter. This is explicitly confirmed in TI's SLAS722G datasheet: ADC10 functionality is exclusive to the MSP430G2x52 series (e.g., MSP430G2252), while the G2x12 series - including MSP430G2212IPW14 - omits ADC10 but retains the full Comparator_A+ module, USI, Timer_A, and low-power features.

What is the maximum operating frequency of the MSP430G2212IPW14 DCO?

The MSP430G2212IPW14 DCO is factory-calibrated at four frequencies: 1 MHz, 8 MHz, 12 MHz, and 16 MHz. The maximum stable operating frequency is 16 MHz, achievable using the DCOCTL and BCSCTL1/2 registers with appropriate RSEL and DCO settings - verified in the "DCO Characteristics" section of SLAS722G.

Can the MSP430G2212IPW14 support I²C communication in hardware?

Yes, the MSP430G2212IPW14 supports hardware I²C via its Universal Serial Interface (USI) module. When configured in I²C mode, pins P1.6 (SCL) and P1.7 (SDA) serve as clock and data lines respectively, with USICTL0/1 registers controlling slave/master mode, start/stop conditions, and address matching - eliminating software bit-banging overhead.

How many I/O pins are available on the MSP430G2212IPW14 in the 14-pin TSSOP package?

The MSP430G2212IPW14 provides 10 usable digital I/O pins in its 14-pin TSSOP package: P1.0–P1.7 (8 pins), P2.6, and P2.7. Pins 1 (DVCC) and 14 (DVSS) are power/ground, and pins 10–11 (RST/NMI/SBWTDIO and TEST/SBWTCK) are dedicated debug I/O - not general-purpose.

Is the MSP430G2212IPW14 pin-compatible with other devices in the MSP430G2xx family?

The MSP430G2212IPW14 shares the same 14-pin TSSOP (PW) package pinout with other G2x12 and G2x52 variants in the same package option (e.g., MSP430G2232IPW14, MSP430G2252IPW14), but functional pin assignments differ where peripherals vary - notably, ADC10-related pins (e.g., A3–A7, VREF±) are NC or repurposed on the MSP430G2212IPW14, making it not a drop-in replacement without firmware validation.
