Product details
Overview
MSP430G2313IPW20 from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller in 20-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 MSP430G2313IPW20 datasheet, MSP430G2313IPW20 pinout, MSP430G2313IPW20 application, or MSP430G2313IPW20 equivalent, key selection criteria include its 4 KB Flash/256 B RAM configuration, absence of ADC10 (distinguishing it from G2x53 variants), 20-pin TSSOP footprint, ultra-low standby current (0.5 µA), and Spy-Bi-Wire debug interface compatibility.
Technical Context
The MSP430G2313IPW20 implements a 16-bit CPU with seven addressing modes and 51-instruction set, paired with a basic clock module offering DCO (calibrated up to 16 MHz), internal LF oscillator, and external crystal support. Its memory map includes 4 KB main Flash, 256 B RAM, and 256 B information memory containing factory DCO calibration data.
Peripheral integration centers on USCI_A0 (UART/LIN/IrDA/SPI) and USCI_B0 (SPI/I²C), dual 16-bit Timer_A modules (TA0 and TA1) with independent capture/compare channels, and Comp_A+ with eight selectable inputs for analog signal comparison or slope A/D conversion - all managed via dedicated interrupt vectors and low-power mode coordination.

FAQ
Does the MSP430G2313IPW20 include an analog-to-digital converter (ADC)?
No, the MSP430G2313IPW20 does not include the ADC10 module. It belongs to the G2x13 series, which omits the 10-bit ADC found in G2x53 variants. Instead, it provides the Comp_A+ analog comparator with eight inputs for threshold detection or slope A/D conversion. This distinction is explicitly noted in the device family datasheet SLAS735J.
What is the maximum operating frequency of the MSP430G2313IPW20?
The MSP430G2313IPW20 supports a maximum DCO frequency of 16 MHz, as confirmed by its basic clock module specifications and factory-calibrated DCO settings stored in information memory. This allows 62.5-ns instruction cycle time in active mode, enabling real-time response in time-critical control loops.
Which debug interface does the MSP430G2313IPW20 support?
The MSP430G2313IPW20 supports the Spy-Bi-Wire (SBW) interface using pins RST/NMI/SBWTDIO (Pin 16) and TEST/SBWTCK (Pin 17). This two-wire interface enables full in-system programming and emulation, eliminating the need for a 4-wire JTAG header and reducing PCB layout complexity.
Can the MSP430G2313IPW20 drive capacitive touch buttons?
Yes, the MSP430G2313IPW20 supports capacitive touch sensing on all P1.x pins via integrated pin oscillator enable bits. It uses Timer_A capture mode to measure frequency shift caused by finger proximity, requiring no external components - a capability confirmed in the MSP430x2xx Family User's Guide and device-specific electrical characteristics.
What are the memory resources of the MSP430G2313IPW20?
The MSP430G2313IPW20 contains 4 KB of main Flash memory for program storage, 256 B of RAM for runtime variables, and 256 B of information memory (including factory DCO calibration data). Memory organization is fixed per the SLAS735J datasheet, with no user-accessible EEPROM or additional non-volatile storage.
