Texas Instruments MSP430G2513IRHB32T

Overview

MSP430G2513IRHB32T from Texas Instruments is an ultra-low-power 16-bit RISC mixed-signal microcontroller featuring 16 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), 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 instrumentation.

For engineers reviewing the MSP430G2513IRHB32T datasheet, MSP430G2513IRHB32T pinout, MSP430G2513IRHB32T application, or MSP430G2513IRHB32T 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 support for five low-power modes with sub-1 µs wake-up from LPM3.

Technical Context

The MSP430G2513IRHB32T implements a 16-bit CPU with 62.5-ns instruction cycle time, constant generators, and register-based architecture optimized for code efficiency. Its clock system integrates a digitally controlled oscillator (DCO), internal LF oscillator, and external crystal support (32 kHz), enabling flexible MCLK/SMCLK/ACLK sourcing.

Peripheral integration includes a programmable on-chip comparator (Comp_A+ with 8 channels), universal serial communication interfaces supporting asynchronous/synchronous protocols, and timer subsystems with capture/compare capability across multiple I/O pins. No ADC10 module is present-this is a defining functional boundary versus MSP430G2x53 family members.

FAQ

Does MSP430G2513IRHB32T include an integrated analog-to-digital converter (ADC)?

No, the MSP430G2513IRHB32T does not include an ADC10 module. This is a deliberate functional distinction from the MSP430G2x53 series (e.g., MSP430G2553). The MSP430G2513IRHB32T retains the on-chip comparator (Comp_A+) and USCI peripherals but omits the 10-bit ADC - confirmed in Table 1 and all functional block diagrams of the SLAS735J datasheet. External ADCs or comparator-based slope-A/D conversion must be used for analog digitization.

What debug interface does MSP430G2513IRHB32T support?

The MSP430G2513IRHB32T supports Spy-Bi-Wire (SBW) via pins RST/NMI/SBWTDIO (Pin 23) and TEST/SBWTCK (Pin 24). This 2-wire interface provides full emulation, flash programming, and real-time debugging without requiring a 4-wire JTAG header. It is fully compatible with TI's MSP-FET and IAR Embedded Workbench, and requires no external voltage - aligning with the device's ultra-low-power design philosophy.

Can MSP430G2513IRHB32T drive capacitive touch buttons?

Yes, the MSP430G2513IRHB32T supports capacitive touch sensing on up to 24 I/O pins (P1.x, P2.x, P3.x) using its integrated pin oscillator and software-based CapTIvate™-compatible methodology. Each pin has individually configurable oscillator enable bits (PCPx.x), allowing simultaneous multi-button detection without external components. This capability is explicitly documented in the "Features" section and functional block diagram of the SLAS735J datasheet.

What is the maximum operating frequency of MSP430G2513IRHB32T?

The MSP430G2513IRHB32T supports internal DCO frequencies up to 16 MHz, calibrated across voltage and temperature. The CPU executes instructions at 62.5 ns per cycle at 16 MHz, and the DCO is factory-calibrated in information memory segment A. External clock sources (e.g., 32.768 kHz crystal on XIN/XOUT) are also supported, but the maximum system clock (MCLK) remains 16 MHz - verified in the "Basic Clock Module Configurations" and "DCO Characteristics" sections of SLAS735J.

Is MSP430G2513IRHB32T pin-compatible with other devices in the MSP430G2x13 family?

Yes, the MSP430G2513IRHB32T shares identical pinout, package (RHB32), and electrical characteristics with all other MSP430G2x13 variants in the 32-pin QFN configuration (e.g., MSP430G2413IRHB32, MSP430G2313IRHB32). Pin functions, power domains (AVCC/AVSS), and debug interface locations are fully consistent across the G2x13 RHB32 family - enabling drop-in replacement where flash/RAM or peripheral requirements align.
