Texas Instruments MSP430G2213IRHB32T

Overview

MSP430G2213IRHB32T from Texas Instruments is an ultra-low-power 16-bit RISC mixed-signal microcontroller featuring 2 kB flash, 256 B RAM, two 16-bit Timer_A modules with three capture/compare registers each, on-chip comparator (Comp_A+), USCI_A0 (UART/LIN/IrDA/SPI) and USCI_B0 (SPI/I²C), and up to 24 capacitive-touch-enabled I/O pins in a 32-pin QFN package. It targets battery-powered sensor nodes and portable instrumentation.

For engineers reviewing the MSP430G2213IRHB32T datasheet, MSP430G2213IRHB32T pinout, MSP430G2213IRHB32T application, or MSP430G2213IRHB32T equivalent, key selection criteria include its 2 kB flash size, absence of ADC10 (distinguishing it from G2x53 variants), 2× Timer_A3 configuration, 32-pin QFN thermal performance, and Spy-Bi-Wire debug interface compatibility.

Technical Context

The MSP430G2213IRHB32T implements a 16-bit CPU with constant generators and seven addressing modes, executing register-to-register operations in one CPU clock cycle. Its clock system integrates a digitally controlled oscillator (DCO) calibrated for 1/8/12/16 MHz operation, internal LF oscillator, and external crystal support (32 kHz).

It supports five low-power modes (LPM0–LPM4), achieving 0.1 µA off-mode current with RAM retention and sub-1 µs wake-up from standby. Peripheral control uses memory-mapped I/O with dedicated interrupt vectors for Timer_A, USCI, comparator, and port interrupts - all accessible via standard instructions without special opcodes.

FAQ

Does the MSP430G2213IRHB32T include an analog-to-digital converter (ADC)?

No, the MSP430G2213IRHB32T does not include the ADC10 module. This distinguishes it from the MSP430G2x53 series (e.g., MSP430G2253). Instead, it features the Comp_A+ analog comparator with eight input channels, supporting slope A/D conversion or binary threshold detection. For designs requiring true digitized analog values, the MSP430G2233IRHB32T - which shares the same package and peripherals but adds ADC10 - is the direct functional upgrade path.

What debug interface does the MSP430G2213IRHB32T support?

The MSP430G2213IRHB32T supports Spy-Bi-Wire (SBW), a 2-wire subset of JTAG implemented via pins RST/NMI/SBWTDIO (pin 23) and TEST/SBWTCK (pin 24). This interface enables full flash programming, breakpoint debugging, and real-time register inspection using TI's MSP-FET or compatible tools. No external debug adapter is required beyond a standard SBW header connection.

Can the MSP430G2213IRHB32T drive capacitive touch buttons?

Yes, the MSP430G2213IRHB32T supports capacitive touch sensing on all P1 and P2 I/O pins via integrated pin oscillators. Each pin has a dedicated enable bit (e.g., P1SEL, P1DIR configuration) to activate the oscillator, allowing self-capacitance or mutual-capacitance measurement without external components. Firmware libraries such as TI's CapTIvate™ can be adapted to this device, though note that MSP430G2213IRHB32T lacks the dedicated CapTIvate peripheral found in later families.

What is the maximum operating frequency of the MSP430G2213IRHB32T DCO?

The digitally controlled oscillator (DCO) in the MSP430G2213IRHB32T is factory-calibrated for four nominal frequencies: 1 MHz, 8 MHz, 12 MHz, and 16 MHz. The maximum guaranteed operating frequency is 16 MHz, achievable using the DCO+ modulation scheme with RSEL and DCO bits configured per calibration constants stored in information memory segment A. System clock (MCLK) may be sourced directly from DCO at this rate.

Is the MSP430G2213IRHB32T pin-compatible with other devices in the MSP430G2x13 family?

Yes, the MSP430G2213IRHB32T is fully pin-compatible with all other 32-pin QFN (RHB) variants in the MSP430G2x13 family, including MSP430G2113IRHB32T, MSP430G2313IRHB32T, and MSP430G2413IRHB32T. They share identical pinouts, electrical characteristics, and package dimensions. Differences lie solely in flash size (1–16 kB), RAM (128–512 B), and peripheral inclusion (e.g., number of Timer_A modules), enabling scalable design reuse across product tiers.
