Texas Instruments MSP430G2513IPW28

Overview

MSP430G2513IPW28 from Texas Instruments is an ultra-low-power 16-bit RISC mixed-signal microcontroller in 28-pin TSSOP packaging, 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), on-chip comparator with eight 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 instrumentation.

For engineers reviewing the MSP430G2513IPW28 datasheet, MSP430G2513IPW28 pinout, MSP430G2513IPW28 application, or MSP430G2513IPW28 equivalent, key selection criteria include its 16 KB flash/512 B RAM configuration, absence of integrated ADC10 (distinguishing it from G2x53 variants), 28-pin TSSOP package with P3 port availability, Spy-Bi-Wire debug interface, and ultra-low-power operation down to 0.1 µA in LPM4 with RAM retention.

Technical Context

The MSP430G2513IPW28 implements a 16-bit RISC CPU with 62.5-ns instruction cycle time, constant generators for code efficiency, and five software-selectable low-power modes optimized for extended battery life. Its clock system integrates a digitally controlled oscillator (DCO) enabling wake-up from standby in under 1 µs, plus support for internal LF oscillator, 32-kHz crystal, or external digital clock source.

Peripheral integration includes dual USCI modules supporting UART, SPI, and I²C protocols; an 8-channel analog comparator usable for slope A/D conversion or signal threshold detection; and two independent 16-bit Timer_A modules (TA0 and TA1), each with three capture/compare registers and multiple clock sources (ACLK, SMCLK, TA0CLK, TA1CLK). Port P3-available only on 28- and 32-pin packages-provides eight additional I/O pins with programmable pullup/pulldown resistors.

FAQ

Does the MSP430G2513IPW28 include an integrated analog-to-digital converter (ADC)?

No, the MSP430G2513IPW28 does not include the ADC10 module. It belongs to the G2x13 series, which omits the 10-bit ADC found in G2x53 variants like the MSP430G2553IPW28. Instead, it provides an 8-channel analog comparator (Comparator_A+) that can perform slope A/D conversion or analog threshold detection without dedicated ADC hardware. This makes the MSP430G2513IPW28 suitable for applications relying on comparator-based signal conditioning rather than digitized analog sampling.

What debug interface does the MSP430G2513IPW28 support?

The MSP430G2513IPW28 supports the Spy-Bi-Wire (SBW) interface using pins 24 (RST/NMI/SBWTDIO) and 25 (TEST/SBWTCK). This two-wire debug protocol enables full in-circuit programming, emulation, and breakpoint debugging without requiring a full 4-pin JTAG connector. The SBW interface operates at standard logic levels, requires no external programming voltage, and is fully supported by TI's Code Composer Studio and MSP430 Flash Emulation Tool (FET) hardware.

How many I/O pins does the MSP430G2513IPW28 provide, and which ports are available?

The MSP430G2513IPW28 provides up to 24 capacitive-touch-enabled I/O pins across Ports P1 (8 pins), P2 (8 pins), and P3 (8 pins). Port P3 is available only on 28-pin and 32-pin packages - confirming its presence on the PW28 variant. All I/O pins support individually configurable pullup/pulldown resistors, interrupt-on-change capability (P1 and P2), and dedicated capacitive-touch oscillator enable bits, enabling robust touch-button implementation without external components.

What clock sources are available for the MSP430G2513IPW28?

The MSP430G2513IPW28 supports multiple clock sources: an internal digitally controlled oscillator (DCO) calibrated to 1/8/12/16 MHz; an internal very-low-power low-frequency (LF) oscillator (~12 kHz); a 32-kHz external crystal connected to XIN/XOUT (pins 27/26); and an external digital clock source. These feed three system clocks - ACLK (for peripherals like timers), MCLK (for CPU), and SMCLK (for USCI and Timer_A) - allowing independent optimization of power and performance per subsystem.

Is the MSP430G2513IPW28 pin-compatible with other devices in the MSP430G2xx family?

Yes, the MSP430G2513IPW28 is pin-compatible with other 28-pin TSSOP devices in the MSP430G2xx family, including the MSP430G2553IPW28, MSP430G2413IPW28, and MSP430G2213IPW28. All share identical pin numbering, electrical characteristics, and peripheral mapping for shared pins. However, functional differences exist - such as ADC10 presence/absence or flash size - meaning firmware and schematic design must account for variant-specific features even when footprint and pinout match.
