Texas Instruments MSP430G2412IPW14

Overview

MSP430G2412IPW14 from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller in 14-pin TSSOP packaging, 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. It operates from 1.8 V to 3.6 V and supports battery-powered sensor nodes requiring sub-µA standby current.

For engineers reviewing the MSP430G2412IPW14 datasheet, MSP430G2412IPW14 pinout, MSP430G2412IPW14 application, or MSP430G2412IPW14 equivalent, key selection criteria include its 14-pin TSSOP footprint, absence of integrated ADC10 (distinguishing it from G2x52 variants), Spy-Bi-Wire debug interface, and support for capacitive-touch I/O - critical for compact, low-cost embedded control designs.

Technical Context

The MSP430G2412IPW14 implements a 16-bit CPU with seven addressing modes and 51 instructions, executing register-to-register operations in one CPU clock cycle. Its basic clock module integrates a digitally controlled oscillator (DCO) calibrated at 1/8/12/16 MHz, plus LF oscillator and external crystal support - enabling wake-up from LPM4 in under 1 µs.

It features two 8-bit I/O ports (P1 and P2), with P1 supporting edge-selectable interrupts and individually configurable pullup/pulldown resistors; P2 provides six general-purpose I/O pins in the 14-pin TSSOP package. The USI module handles synchronous serial communication without dedicated hardware UART or SPI peripherals.

FAQ

Does the MSP430G2412IPW14 include an integrated ADC?

No, the MSP430G2412IPW14 does not include an ADC10 module. It belongs to the G2x12 series, which omits the 10-bit analog-to-digital converter present in G2x52 variants like MSP430G2452IPW14. Its analog capability is limited to the on-chip Comparator_A+ with eight input channels. For designs requiring digitized analog signals, the MSP430G2512IPW14 is the direct pin-compatible alternative with ADC10.

What is the maximum operating frequency of the MSP430G2412IPW14?

The MSP430G2412IPW14 supports a maximum CPU clock frequency of 16 MHz, achieved using the internal digitally controlled oscillator (DCO) with factory-calibrated settings stored in information memory segment A. This allows sub-µs wake-up from LPM4 and real-time response in time-critical sensor polling loops without external crystal dependency.

Can the MSP430G2412IPW14 drive an LCD directly?

No, the MSP430G2412IPW14 does not include an integrated LCD controller or charge pump. It lacks dedicated LCD segment/common drivers and voltage boosting circuitry. For LCD interfacing, external driver ICs or segment-mapped GPIO with software-based multiplexing (limited to very low-duty-cycle displays) are required. Devices like MSP430FR2355 or MSP430F6736 offer native LCD support.

How many I/O pins are available on the MSP430G2412IPW14 in the 14-pin TSSOP package?

The MSP430G2412IPW14 provides eight fully functional I/O pins: P1.0 through P1.7 (pins 2–9), plus P2.6 and P2.7 (pins 13–12). Although port P2 has eight addressable bits, only two physical pins (XIN and XOUT) are routed to the 14-pin TSSOP package - confirmed in Table 1 and functional block diagrams of the SLAS722G datasheet.

Is the MSP430G2412IPW14 compatible with the MSP430 LaunchPad development ecosystem?

Yes, the MSP430G2412IPW14 is fully supported by the MSP430 LaunchPad Development Kit (MSP-EXP430G2) and Code Composer Studio IDE. Its Spy-Bi-Wire interface (RST/NMI and TEST pins) enables programming, debugging, and real-time variable monitoring using the onboard eZ430-RF2500 programmer - no additional hardware tools are required for firmware development or validation.
