Texas Instruments MSP430G2313IPW28

Overview

MSP430G2313IPW28 from Texas Instruments is an ultra-low-power 16-bit RISC mixed-signal microcontroller in 28-pin TSSOP package, featuring 4 KB Flash, 256 B RAM, two 16-bit Timer_A modules with three capture/compare registers each, on-chip comparator (Comp_A+), and Universal Serial Communication Interface (USCI) supporting UART, SPI, and I²C. It operates from 1.8 V to 3.6 V and targets battery-powered sensor nodes and portable instrumentation.

For engineers reviewing the MSP430G2313IPW28 datasheet, MSP430G2313IPW28 pinout, MSP430G2313IPW28 application, or MSP430G2313IPW28 equivalent, key selection criteria include its 4 KB Flash/256 B RAM memory configuration, absence of integrated ADC10 (distinguishing it from G2x53 variants), 28-pin TSSOP footprint, ultra-low standby current (0.5 µA), and Spy-Bi-Wire debug interface compatibility.

Technical Context

The MSP430G2313IPW28 implements a 16-bit CPU with constant generators and seven addressing modes, executing instructions in one cycle at up to 16 MHz via its digitally controlled oscillator (DCO). Its clock system supports ACLK (from 32-kHz crystal or internal LF oscillator), MCLK (CPU clock), and SMCLK (peripheral clock), enabling precise timing control across five low-power modes.

It integrates USCI_A0 (UART/LIN/IrDA/SPI) and USCI_B0 (SPI/I²C), Comp_A+ with eight input channels for analog signal comparison or slope A/D conversion, and two independent Timer_A modules (TA0 and TA1), each with three capture/compare registers and multiple clock sources including TA0CLK, TA1CLK, and SMCLK.

FAQ

Does the MSP430G2313IPW28 include an integrated analog-to-digital converter (ADC)?

No, the MSP430G2313IPW28 does not include the ADC10 module. This distinguishes it from the MSP430G2x53 series (e.g., MSP430G2353IPW28). Instead, it provides the Comp_A+ analog comparator with eight input channels, which supports slope analog-to-digital conversion or hardware threshold detection. The MSP430G2313IPW28 datasheet explicitly states "ADC10 is available on MSP430G2x53 devices only."

What debug interface does the MSP430G2313IPW28 support?

The MSP430G2313IPW28 supports the Spy-Bi-Wire (SBW) interface using pins 24 (RST/NMI/SBWTDIO) and 25 (TEST/SBWTCK). This two-pin interface enables full flash programming, real-time emulation, and breakpoint debugging. It is electrically and protocol-compatible with TI's MSP-FET and LaunchPad development tools, eliminating the need for a four-wire JTAG header.

What is the maximum operating frequency of the MSP430G2313IPW28?

The MSP430G2313IPW28 supports a maximum CPU clock (MCLK) frequency of 16 MHz, achieved using the internal digitally controlled oscillator (DCO) with factory-calibrated settings stored in information memory segment A. The DCO stabilizes in less than 1 µs, enabling rapid wake-up from low-power modes while maintaining timing precision for real-time tasks.

How many I/O pins does the MSP430G2313IPW28 provide, and what special functions do they support?

The MSP430G2313IPW28 provides 24 programmable I/O pins across Ports P1 (8 pins), P2 (8 pins), and P3 (8 pins), all available in the 28-pin TSSOP package. Each pin supports individual direction control, pullup/pulldown resistors, interrupt edge selection, and capacitive-touch oscillator enable. Peripheral functions include Timer_A compare/capture, USCI_A0/USCI_B0 signals, comparator outputs, and clock inputs.

Is the MSP430G2313IPW28 pin-compatible with other devices in the MSP430G2xx family?

Yes, the MSP430G2313IPW28 is pin-compatible with other 28-pin TSSOP variants in the MSP430G2x13 and MSP430G2x53 families, including MSP430G2213IPW28, MSP430G2413IPW28, MSP430G2513IPW28, MSP430G2353IPW28, and MSP430G2453IPW28. Pin functions and package dimensions match exactly, enabling drop-in replacement where memory, ADC, or timer requirements align.
