Texas Instruments MSP430G2513IRHB32R

Overview

MSP430G2513IRHB32R from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller with 16 KB flash, 512 B RAM, two 16-bit Timer_A modules (each with three capture/compare registers), USCI_A0 (UART/LIN/IrDA/SPI) and USCI_B0 (SPI/I²C), on-chip comparator, and up to 24 capacitive-touch 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 MSP430G2513IRHB32R datasheet, MSP430G2513IRHB32R pinout, MSP430G2513IRHB32R application, or MSP430G2513IRHB32R equivalent, key selection criteria include its QFN-32 package, absence of integrated ADC10 (distinguishing it from G2x53 variants), standby current of 0.5 µA, Spy-Bi-Wire debug interface, and compatibility with TI's MSP430G2x13 family toolchain and firmware libraries.

Technical Context

The MSP430G2513IRHB32R 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), internal low-frequency oscillator (VLO), and external crystal support (32 kHz), enabling sub-1 µs wake-up from LPM4.

It features two independent 16-bit Timer_A peripherals (TA0 and TA1), each with three capture/compare registers and multiple clock sources (ACLK, SMCLK, TAxCLK). The USCI_A0 and USCI_B0 modules provide configurable serial communication-UART with auto-baud detection for LIN, IrDA encoding/decoding, synchronous SPI, and I²C master/slave operation-without requiring external components.

FAQ

Does MSP430G2513IRHB32R include an integrated ADC?

No, the MSP430G2513IRHB32R does not include an integrated ADC10 module. This distinguishes it from the MSP430G2x53 family (e.g., MSP430G2553) and aligns it with the G2x13 series, which relies on the on-chip Comparator_A+ for analog threshold detection instead of digitization. Designers requiring analog-to-digital conversion must add an external ADC or select an MSP430G2x53 variant. The MSP430G2513IRHB32R datasheet explicitly omits ADC10 from its feature list and Table 1 options.

What is the maximum operating frequency of MSP430G2513IRHB32R?

The MSP430G2513IRHB32R supports a maximum CPU clock frequency of 16 MHz, achieved using the calibrated internal DCO oscillator. This frequency is fully operational across the rated supply range (1.8 V to 3.6 V) and ambient temperature (–40°C to 85°C), as confirmed by the device's electrical characteristics table and clock system description in SLAS735J. No external crystal is required to reach 16 MHz.

Is MSP430G2513IRHB32R pin-compatible with other 32-pin MSP430G2x devices?

Yes, the MSP430G2513IRHB32R shares identical pinout and package (RHB32 QFN) with all other MSP430G2x13 and MSP430G2x53 devices in the 32-pin variant, including MSP430G2413IRHB32 and MSP430G2553IRHB32. Pin functions-including P1.x, P2.x, P3.x, XIN/XOUT, RST, TEST, AVCC/AVSS, and NC positions-are consistent across this package group, enabling hardware reuse across firmware variants.

How is debug and programming performed on MSP430G2513IRHB32R?

Debug and programming of the MSP430G2513IRHB32R is performed exclusively via the 2-wire Spy-Bi-Wire interface using the RST/NMI/SBWTDIO and TEST/SBWTCK pins. It does not support standard 4-wire JTAG. Additionally, the device includes a factory-programmed UART-based Bootstrap Loader (BSL) accessible through P1.1 (UCA0RXD) and P1.5 (UCA0TXD), enabling firmware updates without dedicated debug hardware.

What power supply domains does MSP430G2513IRHB32R require?

The MSP430G2513IRHB32R requires two independent supply domains: DVCC/DVSS for digital circuitry and AVCC/AVSS for analog subsystems (Comparator_A+). Although both accept 1.8–3.6 V, separating analog and digital supplies-using ferrite beads or LC filtering-is recommended to minimize noise coupling into the comparator inputs and ensure stable reference behavior.
