Texas Instruments MSP430G2313IRHB32R

Overview

MSP430G2313IRHB32R from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller featuring 4 KB flash, 256 B RAM, two 16-bit Timer_A modules with three capture/compare registers each, an on-chip comparator (Comp_A+), and Universal Serial Communication Interfaces (USCI_A0 and USCI_B0) 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 MSP430G2313IRHB32R datasheet, MSP430G2313IRHB32R pinout, MSP430G2313IRHB32R application, or MSP430G2313IRHB32R equivalent, key selection criteria include its QFN-32 package, absence of ADC10 (distinguishing it from G2x53 variants), 4 KB flash size, 256 B RAM, and support for capacitive-touch I/O on up to 24 pins - all critical for low-cost, low-power embedded control designs.

Technical Context

The MSP430G2313IRHB32R implements a 16-bit RISC CPU with 62.5-ns instruction cycle time, digitally controlled oscillator (DCO) enabling sub-1-µs wake-up from LPM4, and five software-selectable low-power modes. Its clock system integrates internal LF and DCO oscillators plus external crystal support (32 kHz or digital source).

Peripheral integration includes USCI_A0 (UART/LIN/IrDA/SPI) and USCI_B0 (SPI/I²C), Comp_A+ with eight input channels, two independent Timer_A3 modules (TA0 and TA1), and Spy-Bi-Wire debug interface. Port P3 is available only in 28-pin and 32-pin packages, confirming full I/O access in the RHB32 variant.

FAQ

Does the MSP430G2313IRHB32R include an analog-to-digital converter (ADC)?

No, the MSP430G2313IRHB32R does not include the ADC10 module. This is explicitly confirmed in the device family documentation: "NOTE: ADC10 is available on MSP430G2x53 devices only." The MSP430G2313IRHB32R belongs to the G2x13 series, which relies on the on-chip comparator (Comp_A+) for analog signal evaluation instead of digitization. For ADC functionality, consider the pin-compatible MSP430G2353IRHB32R.

What is the maximum operating frequency of the MSP430G2313IRHB32R?

The MSP430G2313IRHB32R supports internal DCO frequencies up to 16 MHz, as confirmed by the "Internal Frequencies up to 16 MHz With Four Calibrated Frequency" specification in the datasheet. The DCO is factory-calibrated and can be configured via RSEL and DCO bits; actual achievable frequency depends on supply voltage and temperature but remains within the 1.8–3.6 V operational range.

Is the MSP430G2313IRHB32R pin-compatible with other devices in the MSP430G2x13 family?

Yes, the MSP430G2313IRHB32R shares identical pinout and electrical characteristics with other 32-pin QFN (RHB) variants in the G2x13 family, including MSP430G2213IRHB32, MSP430G2413IRHB32, and MSP430G2513IRHB32. All use the same RHB32 top-view layout, terminal functions, and package dimensions - enabling drop-in replacement where flash/RAM/peripheral requirements align.

How is debug and programming performed on the MSP430G2313IRHB32R?

Debug and programming of the MSP430G2313IRHB32R is supported via Spy-Bi-Wire (SBW) using pins RST/NMI/SBWTDIO (Pin 23) and TEST/SBWTCK (Pin 24). It also supports UART-based bootloader (BSL) programming using P1.1 (RXD) and P1.5 (TXD). No external high-voltage programming voltage is required - both methods operate within the 1.8–3.6 V supply range.

What low-power modes are supported by the MSP430G2313IRHB32R?

The MSP430G2313IRHB32R supports six operating modes: Active Mode (AM) and five low-power modes (LPM0–LPM4). LPM4 disables all clocks and draws only 0.1 µA with RAM retention, while LPM3 retains ACLK for real-time clock operation at 0.2 µA. Wake-up from LPM4 to AM occurs in less than 1 µs due to the fast-stabilizing DCO oscillator.
