Product details
Overview
MSP430G2212IPW20 from Texas Instruments is an ultra-low-power 16-bit RISC mixed-signal microcontroller in 20-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, on-chip comparator, and brownout detection - deployed in battery-powered sensor nodes and portable instrumentation.
For engineers reviewing the MSP430G2212IPW20 datasheet, MSP430G2212IPW20 pinout, MSP430G2212IPW20 application, or MSP430G2212IPW20 equivalent, key selection criteria include its 1.8–3.6 V supply range, five power-saving modes, <1 µs wake-up from standby, Spy-Bi-Wire debug interface, and absence of integrated ADC10 (distinguishing it from G2x52 variants).
Technical Context
The MSP430G2212IPW20 implements a 16-bit CPU with seven addressing modes and 51 instructions, paired with a basic clock module supporting internal DCO (calibrated at 1/8/12/16 MHz), LF oscillator, and external crystal input. Its peripheral set excludes ADC10 but includes USI, Comparator_A+ with eight channels, and Timer_A3 with three CC registers.
Power management is centered on six operating modes (AM + LPM0–LPM4), enabling sub-µA standby (0.5 µA) and off-mode (0.1 µA with RAM retention). I/O ports P1 and P2 support individually configurable pullup/pulldown resistors, edge-selectable interrupts, and capacitive-touch enable bits - all controlled via dedicated SFRs mapped to 0x0020–0x0042.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | 16-bit RISC CPU with 16 general-purpose registers and constant generators; enables single-cycle register operations and high code efficiency. |
| Flash / RAM | 2 kB flash program memory and 256 B RAM - sufficient for compact firmware with real-time sensor processing and communication stacks. |
| Supply Voltage | 1.8 V to 3.6 V - supports direct operation from single-cell Li-ion, alkaline, or coin-cell batteries without regulation. |
| Power Modes | Active mode (220 µA @ 1 MHz, 2.2 V); Standby (0.5 µA); Off with RAM retention (0.1 µA) - optimized for intermittent sensing duty cycles. |
| Timer & Interface | One 16-bit Timer_A with three capture/compare registers; USI supporting hardware SPI and I²C - eliminates need for bit-banged protocols. |
| Clock Sources | Digital Controlled Oscillator (DCO) with four factory-calibrated frequencies (1/8/12/16 MHz); internal LF oscillator; external 32-kHz crystal or digital clock input. |
| Debug Interface | Spy-Bi-Wire (2-wire JTAG) - enables full emulation, flash programming, and breakpoint debugging using minimal PCB footprint. |
Pinout & Package
Package: 20-pin TSSOP (PW), 0.65 mm pitch, body size 6.5 × 4.4 mm, thermal pad not present. Pin functions validated per TI SLAS722G Rev. May 2013, Table 2 and PW-package top-view diagram.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 16, 15 | DVCC / AVCC / DVSS | Digital supply (1.8–3.6 V), analog supply (tied to DVCC), and digital ground - require local decoupling (100 nF) near pins 1 & 16. |
| 2–9, 11–14, 17–20 | P1.x / P2.x I/O | Two 8-bit bidirectional ports: P1.0–P1.7 and P2.0–P2.5 (P2.6/P2.7 multiplexed with XIN/XOUT); each pin supports interrupt, pullup/down, and capacitive-touch enable. |
| 10, 11 | RST/NMI/SBWTDIO / TEST/SBWTCK | Spy-Bi-Wire debug interface: bidirectional data (SBWTDIO) and clock (SBWTCK); RST/NMI also serves as non-maskable interrupt input. |
| 18, 19 | XOUT/P2.7 / XIN/P2.6/TA0.1 | Crystal oscillator terminals - XIN accepts 32-kHz crystal or external clock; XOUT drives crystal; both double as GPIO (P2.6/P2.7) when oscillator disabled. |
| 5, 6, 14 | P1.3/ADC10CLK/CAOUT/VREF-/VEREF-/CA3 / P1.4/SMCLK/A4/VREF+/VEREF+/CA4/TCK / AVSS | VREF± pins are no-connect on MSP430G2212IPW20 (no ADC10); CAOUT and comparator inputs remain functional; AVSS tied to DVSS per design. |
