Product details
Overview
MSP430G2412IPW14R from Texas Instruments is an ultra-low-power 16-bit RISC mixed-signal 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, on-chip comparator, and eight programmable I/O pins - deployed in battery-powered sensor nodes and portable instrumentation.
For engineers reviewing the MSP430G2412IPW14R datasheet, MSP430G2412IPW14R pinout, MSP430G2412IPW14R application, or MSP430G2412IPW14R equivalent, key selection criteria include supply voltage range (1.8–3.6 V), active-mode current (220 µA at 1 MHz), five low-power modes, Spy-Bi-Wire debug interface, and absence of integrated ADC10 - distinguishing it from MSP430G2x52 variants.
Technical Context
The MSP430G2412IPW14R implements a 16-bit CPU with seven addressing modes and constant generators for high code efficiency. Its clock system integrates a digitally controlled oscillator (DCO) calibrated to 1 MHz, 8 MHz, 12 MHz, and 16 MHz, plus internal LF oscillator and external crystal support (32 kHz).
It supports Spy-Bi-Wire emulation via RST/NMI and TEST pins, uses two 8-bit I/O ports (P1 with 8 pins, P2 with 2 pins in PW14 package), and provides individually configurable pullup/pulldown resistors and capacitive-touch enable bits per I/O - all managed through dedicated SFRs including IE1/IE2, IFG1/IFG2, and port control registers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | 16-bit RISC CPU with 62.5-ns instruction cycle; register-to-register operations execute in one CPU clock cycle. |
| Flash / RAM | 8 KB Flash program memory + 256 B RAM; supports in-system programming via Spy-Bi-Wire without external voltage. |
| Supply Voltage | 1.8 V to 3.6 V operation; enables direct use with single Li-ion or dual alkaline cells. |
| Active Current | 220 µA at 1 MHz, 2.2 V - defines baseline power budget for continuous sensing tasks. |
| Low-Power Modes | Five software-selectable modes; LPM4 draws only 0.1 µA with RAM retention - critical for multi-year battery life. |
| Debug Interface | Spy-Bi-Wire (2-wire JTAG subset) using RST/NMI and TEST pins - reduces PCB footprint vs full JTAG. |
| Timer Resource | One 16-bit Timer_A (TA0) with three capture/compare registers (TA0.0, TA0.1, TA0.2) - supports PWM, input capture, and interval timing. |
Pinout & Package
Package: 14-pin TSSOP (PW), 5.0 mm × 6.4 mm, 0.65 mm pitch, surface-mount. Pin functions validated per TI SLAS722G Rev. May 2013, Table 2 and PW package top-view diagram.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (DVCC) | Digital supply voltage | Primary VDD connection; must be decoupled locally to suppress switching noise. |
| 2 (P1.0/TA0CLK/ACLK/A0/CA0) | Multi-function I/O | Configurable as Timer_A clock input, ACLK output, analog input A0, or comparator CA0 - no ADC10 function on G2412. |
| 3 (P1.1/TA0.0/A1/CA1) | Timer/capture I/O | Supports CCI0A capture or Out0 PWM output; also serves as analog input A1 and comparator CA1. |
| 4 (P1.2/TA0.1/A2/CA2) | Timer/capture I/O | Supports CCI1A capture or Out1 PWM output; also analog input A2 and comparator CA2. |
| 5 (P1.3/ADC10CLK/CAOUT/A3/CA3) | Comparator output | CAOUT is active; ADC10CLK and A3 functions are not available - confirmed absent in MSP430G2x12 family. |
| 6 (P1.4/TA0.2/SMCLK/A4/CA4/TCK) | Timer/clock I/O | Supports CCI2A capture or Out2 PWM; SMCLK output; JTAG TCK during programming. |
| 7 (P1.5/TA0.0/SCLK/A5/CA5/TMS) | Timer/JTAG I/O | Out0 PWM or SPI clock; JTAG TMS during programming; no ADC10 A5 function. |
| 8 (P1.6/TA0.1/SDO/SCL/A6/CA6/TDI/TCLK) | USI/Timer I/O | USI data output (SPI) or I²C clock; also TDI for Spy-Bi-Wire; no A6 analog input. |
| 9 (P1.7/SDI/SDA/CAOUT/A7/CA7/TDO/TDI) | USI/Comparator I/O | USI data input (SPI) or I²C data; CAOUT shared output; no A7 analog input. |
| 10 (RST/NMI/SBWTDIO) | Reset/debug I/O | Active-low reset; NMI input; bidirectional Spy-Bi-Wire data I/O - primary debug channel. |
| 11 (TEST/SBWTCK) | Debug clock | Test mode select during programming; SBWTCK input for Spy-Bi-Wire clock - requires external signal source. |
| 12 (XOUT/P2.7) | Oscillator output | Crystal oscillator output; if used as general I/O, P2SEL.7 must be cleared to avoid excess current. |
| 13 (XIN/P2.6/TA0.1) | Oscillator input | Crystal or external clock input; also TA0.1 compare output - dual-role pin with priority to oscillator when enabled. |
| 14 (DVSS) | Digital ground | Reference return path for DVCC; must be connected to system ground plane with low-inductance trace. |
Key Features
| Feature | Design Value |
|---|---|

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 |
|---|---|---|---|
| MSP430G2452IPW14R | Includes 10-bit ADC10 with 8-channel autoscan; same Flash/RAM, package, and USI/peripheral set. | Required where analog sensor signals need direct digitization without external ADC. | Select MSP430G2452IPW14R only if on-chip ADC10 functionality is mandatory - otherwise MSP430G2412IPW14R offers lower cost and identical power/performance for digital-only I/O designs. |
| MSP430G2312IPW14R | 4 KB Flash, 256 B RAM, identical peripherals and power specs; lacks Timer_A capture/compare register TA0.2. | Suitable for simpler timing tasks (e.g., basic PWM or single-interval timing) without three independent compare outputs. | Choose MSP430G2312IPW14R when firmware size fits in 4 KB and only two Timer_A compare channels are needed - reduces cost while maintaining pin compatibility and debug interface. |
Compared with MSP430G2452IPW14R, the MSP430G2412IPW14R omits ADC10 but retains full Timer_A and USI capability; versus MSP430G2312IPW14R, it adds the third capture/compare register (TA0.2) for enhanced PWM or input-capture flexibility - making it optimal for compact, analog-input-free control applications demanding precise timing.

FAQ
Does MSP430G2412IPW14R include an integrated ADC?
No, MSP430G2412IPW14R does not include an ADC. It belongs to the MSP430G2x12 series, which omits the ADC10 module present in the G2x52 series. Analog signal acquisition requires external ADC or resistor-divider networks with the on-chip comparator. This distinction is explicitly documented in TI's SLAS722G datasheet, Table 1 and functional block diagrams.
What debug interface does MSP430G2412IPW14R support?
MSP430G2412IPW14R supports Spy-Bi-Wire (SBW), a 2-wire subset of JTAG, using pins RST/NMI/SBWTDIO (Pin 10) and TEST/SBWTCK (Pin 11). No external programming voltage is required. Full JTAG is not supported on this device - confirmed in the "On-Chip Emulation Logic" feature list and terminal functions table of SLAS722G.
How many I/O pins are available on MSP430G2412IPW14R in the TSSOP-14 package?
MSP430G2412IPW14R provides eight programmable I/O pins on Port 1 (P1.0–P1.7) and two on Port 2 (P2.6, P2.7), totaling ten usable digital I/Os. Pins P2.0–P2.5 are not bonded out in the 14-pin TSSOP package - verified in TI's SLAS722G Table 1 and "DEVICE PINOUTS" section.
Can MSP430G2412IPW14R drive capacitive-touch buttons?
Yes, MSP430G2412IPW14R supports capacitive-touch sensing on all P1.x pins via individually enabled pin oscillators. Each P1 pin has a dedicated bit in the P1SEL register to activate the oscillator, enabling low-cost touch-button detection without external components - detailed in the "Digital I/O" section and peripheral file map of SLAS722G.
What is the maximum operating frequency of MSP430G2412IPW14R's DCO?
The digitally controlled oscillator (DCO) in MSP430G2412IPW14R is factory-calibrated up to 16 MHz across four frequencies (1/8/12/16 MHz), with modulation enabling fine-tuning. The DCO stabilizes in less than 1 µs - critical for fast wake-up from LPM modes. Calibration constants are stored in information memory segment A, as specified in SLAS722G Section "Calibration Data Stored in Information Memory Segment A".
