Product details
Overview
MSP430G2313IPW20R 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 MSP430G2313IPW20R datasheet, MSP430G2313IPW20R pinout, MSP430G2313IPW20R application, or MSP430G2313IPW20R 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, USCI dual-channel support, and sub-1 µs wake-up from LPM4 standby mode.
Technical Context
The MSP430G2313IPW20R implements a 16-bit RISC CPU with 62.5-ns instruction cycle time, digitally controlled oscillator (DCO) calibrated for 1 MHz, 8 MHz, 12 MHz, and 16 MHz operation, and five software-selectable low-power modes (LPM0–LPM4). Its clock system integrates ACLK (from 32-kHz crystal or internal LF oscillator), MCLK (CPU clock), and SMCLK (peripheral clock).
It includes two independent 16-bit Timer_A modules (TA0 and TA1), each with three capture/compare registers and multiple output modes; Comp_A+ with eight selectable inputs for analog signal comparison or slope A/D conversion; and USCI_A0 (UART/SPI/IrDA/LIN) plus USCI_B0 (SPI/I²C) for flexible serial communication. Port P3 is not available in the 20-pin PW20 package.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | 16-bit RISC CPU with 62.5-ns instruction cycle; enables deterministic real-time control in resource-constrained embedded systems. |
| Flash / RAM | 4 KB Flash program memory and 256 B RAM; sufficient for compact firmware with limited data buffering, no ADC calibration storage required. |
| Supply Voltage | 1.8 V to 3.6 V operation; supports direct connection to single-cell Li-ion or alkaline batteries without regulation. |
| Ultra-Low Power | Active mode: 230 µA at 1 MHz/2.2 V; Standby: 0.5 µA; Off mode (RAM retention): 0.1 µA - extends battery life in intermittent-sensing applications. |
| Timers | Two 16-bit Timer_A modules (TA0, TA1), each with three capture/compare registers; supports PWM generation, input capture, and interval timing across multiple peripherals. |
| Communication | USCI_A0 (UART/SPI/IrDA/LIN) + USCI_B0 (SPI/I²C); enables host interface, sensor bus connectivity, and bootloader over UART without external transceivers. |
| Comparator | Comp_A+ with eight analog inputs and CAOUT output; performs threshold detection, window comparison, or slope-based A/D conversion without ADC hardware. |
Pinout & Package
Package: 20-pin TSSOP (PW20), 0.65 mm pitch, body size 6.5 mm × 4.4 mm, RoHS-compliant, surface-mount compatible.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 DVCC | Digital supply voltage | Primary 1.8–3.6 V power input for digital core and I/O banks; requires local 100 nF decoupling. |
| 2 P1.0/TA0CLK/ACLK/A0/CA0 | Multi-function I/O | Configurable as timer clock input, ACLK output, analog input A0, or comparator input CA0 - enables flexible clock tree or analog sensing. |
| 5 P1.3/ADC10CLK/CAOUT/VREF−/VEREF−/A3/CA3 | Comparator output & reference | CAOUT delivers comparator result; VREF−/VEREF− sets negative reference - used for precision thresholding or ratiometric measurements (no ADC10 present). |
| 6 P1.4/SMCLK/CA4/TCK/VREF+/VEREF+/A4/UCB0STE/UCA0CLK | System clock & interface control | SMCLK output drives peripherals; UCA0CLK selects synchronous UART clock; VREF+/VEREF+ sets positive reference for comparator - critical for stable analog comparisons. |
| 16 RST/NMI/SBWTDIO | Reset & debug I/O | Active-low reset input; NMI source; Spy-Bi-Wire data I/O - enables in-system programming and debugging via two-wire interface. |
| 17 TEST/SBWTCK | Debug clock | Spy-Bi-Wire test clock input - required for JTAG/SBW programming; must be pulled high during normal operation. |
| 19 XIN/P2.6/TA0.1 | Clock input & timer function | Accepts 32-kHz crystal for ACLK; also serves as TA0.1 compare output - allows shared pin usage between timing and peripheral functions. |
| 20 DVSS | Digital ground | Reference return path for digital logic and I/O; must be connected to system ground plane with low-inductance path. |
Key Features
| Feature | Design Value |
|---|---|
| Five low-power operating modes (LPM0–LPM4) | Enables <1 µs wake-up from LPM4, reducing average current in duty-cycled sensor nodes to sub-µA levels. |
| On-chip comparator (Comp_A+) with 8 inputs | Performs analog threshold detection, zero-crossing, or slope A/D without ADC hardware - saves Flash/RAM and simplifies BOM. |
| USCI_A0 + USCI_B0 dual serial interfaces | Supports simultaneous UART (host comms) and I²C (sensor bus) or dual SPI (memory + display), eliminating need for external protocol translators. |
| Capacitive-touch enabled I/O pins | Individual pin oscillator enable bits allow low-cost touch-button implementation using only MCU resources and PCB traces - no dedicated touch controller required. |
| Integrated Spy-Bi-Wire emulation logic | Enables full-speed debugging and flash programming via two pins (SBWTDIO, SBWTCK), reducing debug header footprint and cost vs. 4-pin JTAG. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430G2213IPW20R | 2 KB Flash, 256 B RAM, same peripherals and package; lacks calibrated DCO frequencies above 1 MHz. | Suitable for simpler firmware with smaller code footprint; not recommended if >1 MHz clock stability or higher Flash headroom needed. | Select when cost sensitivity outweighs need for 4 KB Flash or multi-MHz DCO calibration. |
| MSP430G2353IPW20R | 4 KB Flash, 256 B RAM, adds 10-bit ADC10 with 8-channel autoscan and internal reference; identical pinout and core peripherals. | Required where analog sensor digitization (e.g., thermistor, potentiometer) is needed alongside comparator functions. | Choose when ADC functionality is mandatory; note ADC10 increases active current slightly and consumes additional Flash for driver code. |
Compared with MSP430G2213IPW20R, the MSP430G2313IPW20R provides double Flash capacity and factory-calibrated DCO up to 16 MHz for timing-critical tasks; versus MSP430G2353IPW20R, it omits ADC10 to reduce cost and power in purely comparator- or digital-sensing applications.

FAQ
Does the MSP430G2313IPW20R include an analog-to-digital converter (ADC)?
No, the MSP430G2313IPW20R does not include the ADC10 module. It belongs to the G2x13 series, which features the on-chip comparator (Comp_A+) but omits the 10-bit ADC found in G2x53 variants like MSP430G2353IPW20R. Analog threshold detection must be performed using Comp_A+, and slope A/D conversion is supported via software-controlled timing loops.
What is the maximum operating frequency of the MSP430G2313IPW20R?
The MSP430G2313IPW20R supports a maximum DCO frequency of 16 MHz, calibrated and stored in information memory segment A. The device achieves this via RSEL and DCO register settings, with modulation (MODx bits) enabling fine frequency tuning. At 16 MHz, instruction execution time is 62.5 ns, and active current rises to approximately 420 µA at 3.3 V.
Can the MSP430G2313IPW20R be programmed in-system without a JTAG emulator?
Yes, the MSP430G2313IPW20R supports in-system programming via its built-in Bootstrap Loader (BSL) using UART. Pins P1.1 (UCA0RXD) and P1.5 (UCA0TXD) serve as BSL data I/O. Programming requires a password, and the BSL is protected by a security fuse. No external programming voltage is needed - operation is fully 1.8–3.6 V compatible.
How many I/O pins does the MSP430G2313IPW20R provide, and are they all individually configurable?
The MSP430G2313IPW20R provides 16 general-purpose I/O pins across Ports P1 and P2 (P1.0–P1.7 and P2.0–P2.7). Each pin is individually configurable for input/output direction, pullup/pulldown resistor enable, interrupt edge select (rising/falling), and peripheral function mapping. Port P3 is not available in the 20-pin TSSOP package.
What debug interface does the MSP430G2313IPW20R support, and what pins are required?
The MSP430G2313IPW20R supports Spy-Bi-Wire (SBW) debugging, a two-wire variant of JTAG. It requires only two pins: RST/NMI/SBWTDIO (Pin 16) for bidirectional data and TEST/SBWTCK (Pin 17) for clock. This reduces debug header footprint and cost compared to full 4-pin JTAG, while maintaining full-speed flash programming and real-time debugging capability.
