Texas Instruments MSP430G2413IRHB32T

Overview

MSP430G2413IRHB32T from Texas Instruments is an ultra-low-power 16-bit RISC mixed-signal microcontroller featuring 8 KB flash, 512 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 with 8 channels, and up to 24 capacitive-touch-enabled I/O pins. It operates from 1.8 V to 3.6 V and targets battery-powered sensor nodes and portable measurement systems.

For engineers reviewing the MSP430G2413IRHB32T datasheet, MSP430G2413IRHB32T pinout, MSP430G2413IRHB32T application, or MSP430G2413IRHB32T equivalent, key selection criteria include its QFN-32 package, absence of integrated ADC10 (distinguishing it from G2x53 variants), Spy-Bi-Wire debug interface, brownout detection, and five low-power modes enabling sub-1 µs wake-up from standby.

Technical Context

The MSP430G2413IRHB32T implements a 16-bit CPU with seven addressing modes and 51 instructions, paired with a digitally controlled oscillator (DCO) calibrated for 1 MHz, 8 MHz, 12 MHz, and 16 MHz operation. Its clock system supports ACLK (from 32-kHz crystal or internal LF oscillator), MCLK (CPU clock), and SMCLK (peripheral clock).

Peripheral integration includes dual USCI modules supporting asynchronous UART with auto-baudrate detection (LIN), synchronous SPI, and I²C master/slave; a flexible analog comparator usable for slope A/D conversion; and Timer_A modules supporting capture, compare, PWM, and interval timing. Port P3 (8 pins) is available only in 28- and 32-pin packages like the RHB32.

FAQ

Does MSP430G2413IRHB32T include an integrated analog-to-digital converter (ADC)?

No, MSP430G2413IRHB32T does not include the ADC10 module. It belongs to the G2x13 series, which omits the 10-bit ADC present in G2x53 variants like MSP430G2453IRHB32. The device retains the 8-channel analog comparator (Comp_A+) for threshold detection and slope A/D conversion, but raw analog digitization requires external ADC or alternative MCU selection.

What debug interface does MSP430G2413IRHB32T support?

MSP430G2413IRHB32T supports Spy-Bi-Wire (SBW) via RST/NMI/SBWTDIO (Pin 23) and TEST/SBWTCK (Pin 24). This two-wire interface enables full in-circuit debugging, flash programming, and real-time emulation using TI's MSP-FET or compatible tools - eliminating the need for a 4-wire JTAG header and saving PCB space.

Is MSP430G2413IRHB32T pin-compatible with other devices in the MSP430G2x13 family?

Yes, MSP430G2413IRHB32T shares identical pinout and electrical characteristics with other RHB32-packaged G2x13 variants (e.g., MSP430G2313IRHB32, MSP430G2213IRHB32). Differences are limited to flash size (8 KB vs. 4 KB vs. 2 KB), RAM (512 B vs. 256 B), and Timer_A count (two modules vs. one), all software-configurable without hardware changes.

What is the maximum operating frequency of the DCO in MSP430G2413IRHB32T?

The digitally controlled oscillator (DCO) in MSP430G2413IRHB32T is factory-calibrated for four frequencies: 1 MHz, 8 MHz, 12 MHz, and 16 MHz. These settings are stored in information memory segment A. While the DCO can be tuned between calibration points, the guaranteed operational range per datasheet is up to 16 MHz at VCC ≥ 2.2 V and TA ≤ 85°C.

Can MSP430G2413IRHB32T drive capacitive touch buttons without external components?

Yes, MSP430G2413IRHB32T supports capacitive touch sensing on up to 24 I/O pins using its integrated pin oscillator circuitry. Each pin can be configured to generate a relaxation oscillator whose frequency shifts with finger proximity - enabling self-contained touch-button, slider, or wheel implementations without external RC networks or dedicated touch ICs.
