Texas Instruments MSP430G2413IPW20R

Overview

MSP430G2413IPW20R from Texas Instruments is an ultra-low-power 16-bit RISC mixed-signal microcontroller in 20-pin TSSOP package, featuring 8 KB flash, 256 B RAM, two 16-bit Timer_A modules with three capture/compare registers each, USCI_A0 (UART/LIN/IrDA/SPI) and USCI_B0 (SPI/I²C), on-chip comparator, and up to 16 capacitive-touch I/O pins. It targets battery-powered sensor nodes and portable instrumentation.

For engineers reviewing the MSP430G2413IPW20R datasheet, MSP430G2413IPW20R pinout, MSP430G2413IPW20R application, or MSP430G2413IPW20R equivalent, key selection criteria include its 8 KB flash size, absence of integrated ADC10 (distinguishing it from G2x53 variants), 20-pin TSSOP footprint, Spy-Bi-Wire debug interface, and verified 1.8–3.6 V supply operation with sub-1 µs wake-up from LPM4.

Technical Context

The MSP430G2413IPW20R implements a 16-bit RISC CPU with constant generators and seven addressing modes, executing instructions in one CPU clock cycle. Its basic clock module integrates a digitally controlled oscillator (DCO), internal low-frequency oscillator (VLO), and external crystal support (32 kHz), enabling flexible clock sourcing for MCLK, SMCLK, and ACLK.

It supports five low-power modes (LPM0–LPM4), with LPM4 drawing only 0.1 µA (RAM retention). The device includes two independent 16-bit Timer_A peripherals (TA0 and TA1), each with three capture/compare registers and multiple clock sources, and dual USCI modules supporting asynchronous/synchronous serial protocols without requiring external components.

FAQ

Does the MSP430G2413IPW20R include an integrated ADC?

No, the MSP430G2413IPW20R does not include an integrated ADC10 module. This is explicitly confirmed in the datasheet: "NOTE: ADC10 is available on MSP430G2x53 devices only." The MSP430G2413IPW20R belongs to the G2x13 series, which omits the ADC10 peripheral but retains the 8-channel analog comparator (Comp_A+) for slope A/D conversion and threshold detection. For designs requiring direct analog-to-digital conversion, the MSP430G2453IPW20R is the functional counterpart with identical package and flash/RAM configuration plus ADC10.

What is the maximum operating frequency of the MSP430G2413IPW20R?

The MSP430G2413IPW20R supports a maximum CPU clock (MCLK) frequency of 16 MHz, enabled by its digitally controlled oscillator (DCO) with factory-calibrated settings stored in information memory segment A. The DCO operates across four calibrated frequency ranges (RSEL0–RSEL3), and the device achieves stable 16 MHz operation at 3.0 V and 25°C per calibration data in SLAS735J. External clock sources-including 32.768 kHz crystals on XIN/XOUT-can also drive ACLK or SMCLK independently of the DCO.

Can the MSP430G2413IPW20R be programmed using Spy-Bi-Wire?

Yes, the MSP430G2413IPW20R supports full in-system programming and debugging via the two-wire Spy-Bi-Wire (SBW) interface using pins RST/NMI/SBWTDIO (Pin 16) and TEST/SBWTCK (Pin 17). This eliminates the need for a 4-wire JTAG header, reduces PCB footprint, and lowers system cost. The SBW interface is fully compatible with TI's MSP-FET and MSP430 LaunchPad development tools, and enables flash programming, RAM inspection, breakpoint setting, and real-time register monitoring without removing the device from the target board.

How many I/O pins support capacitive touch sensing on the MSP430G2413IPW20R?

The MSP430G2413IPW20R supports capacitive touch sensing on up to 16 I/O pins-specifically all eight pins of Port 1 (P1.0–P1.7) and all eight pins of Port 2 (P2.0–P2.7). Each pin includes a dedicated oscillator enable bit (e.g., P1SEL.x, P2SEL.x) that activates an internal relaxation oscillator for self-capacitance measurement. No external RC components are required for basic touch detection, though external electrodes and shielding are needed for robust implementation. Port 3 is not available on the 20-pin PW20 package.

What are the key differences between MSP430G2413IPW20R and MSP430G2453IPW20R?

The MSP430G2413IPW20R and MSP430G2453IPW20R share identical package (20-pin TSSOP), flash (8 KB), RAM (256 B), pinout, and core peripherals-including USCI_A0/B0, two Timer_A modules, and Comp_A+. The sole functional difference is the presence of the 10-bit ADC10 module in the G2453 variant, which is absent in the G2413. All ADC10-related pins (e.g., A0–A7, VREF±) remain available as general-purpose I/O or comparator inputs on the G2413. This makes the G2453 a drop-in upgrade when analog digitization is added to an existing G2413 design.
