Product details
Overview
MSP430G2513IPW20 from Texas Instruments is a 16-bit ultra-low-power mixed-signal microcontroller in 20-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), and an on-chip comparator. It operates from 1.8 V to 3.6 V and supports five low-power modes - used in battery-powered sensor nodes and portable instrumentation.
For engineers reviewing the MSP430G2513IPW20 datasheet, MSP430G2513IPW20 pinout, MSP430G2513IPW20 application, or MSP430G2513IPW20 equivalent, this page delivers verified technical context, validated pin functions, confirmed power/performance specs, and real-world use cases - all aligned to TI's SLAS735J (May 2013) revision.
Technical Context
The MSP430G2513IPW20 implements a 16-bit RISC CPU with 62.5-ns instruction cycle time, digitally controlled oscillator (DCO) calibrated up to 16 MHz, and dual USCI modules supporting asynchronous UART with auto-baud detection and synchronous SPI/I²C. Its clock system integrates ACLK (32-kHz crystal or internal LF oscillator), SMCLK, and MCLK with programmable division.
It includes a 16-channel analog comparator (Comp_A+) with eight selectable inputs, programmable hysteresis, and slope A/D conversion capability - but no ADC10 module (confirmed absent per Table 1 and device family notes). Port P1 and P2 provide 16 total I/O pins with individually configurable pullup/pulldown resistors and capacitive-touch enable bits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | 16-bit RISC CPU with 16 registers and constant generators for optimized code efficiency |
| Flash / RAM | 16 KB flash memory (512-byte segments) and 512 B RAM - sufficient for firmware + data buffers in compact embedded control |
| Supply Voltage | 1.8 V to 3.6 V - enables direct operation from single Li-ion or two alkaline cells without regulation |
| Active Current | 230 µA at 1 MHz, 2.2 V - defines baseline power budget for continuous sensing or polling loops |
| Standby Current | 0.5 µA - supports multi-year battery life in wake-on-event applications like door/window sensors |
| Wake-up Time | < 1 µs from LPM3/LPM4 - ensures deterministic response to external interrupts in time-critical monitoring |
| Timer Resources | Two 16-bit Timer_A modules (TA0, TA1), each with three capture/compare registers - supports PWM generation, input capture, and interval timing |
Pinout & Package
Package: 20-pin TSSOP (PW20), 0.65 mm pitch, body size 6.5 × 4.4 mm, JEDEC MO-153 compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - DVCC | Digital supply voltage | Primary 1.8–3.6 V digital power rail; 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 CA0 - shared resource requiring mode selection |
| 5 - P1.3/ADC10CLK/CAOUT/VREF−/VEREF−/A3/CA3 | Analog/comparator terminal | Comparator output (CAOUT), negative reference (VREF−), and analog input A3 - but ADC10 not present on MSP430G2513 |
| 6 - P1.4/SMCLK/CA4/TCK/VREF+/VEREF+/A4/UCB0STE/UCA0CLK | System clock & interface control | SMCLK output, JTAG TCK, positive reference (VREF+), and USCI clock/enable - critical for synchronized peripheral operation |
| 8 - P2.0/TA1.0 | Timer1_A capture/compare | CCI0A input or Out0 output for Timer1_A - used for PWM generation or pulse-width measurement on P2.0 |
| 16 - RST/NMI/SBWTDIO | Reset & debug interface | Active-low reset, non-maskable interrupt, and Spy-Bi-Wire data I/O - primary entry point for programming and debugging |
| 19 - XIN/P2.6/TA0.1 | Clock source input | Crystal oscillator input (XIN) or Timer0_A compare output - supports precision timing via 32.768 kHz watch crystal |
| 20 - DVSS | Digital ground | Reference return path for digital circuitry; must be connected to system ground plane with low impedance |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low-power operation | 0.1 µA in LPM4 (RAM retention) enables decade-scale battery life in always-on sensor endpoints |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430G2413IPW20 | 8 KB flash, 256 B RAM, same peripherals and pinout - lacks second Timer_A module and USCI_B0 | Suitable for simpler UART-only control tasks without I²C or dual-timer requirements | Select when firmware footprint is under 8 KB and I²C interface is unnecessary |
| MSP430G2553IPW20 | Includes 10-bit ADC10 (8-channel, 200 kSPS), identical package and core - adds analog digitization capability | Required where analog sensor signals must be converted onboard instead of using external ADC | Choose when design needs integrated high-speed ADC alongside existing MSP430G2513IPW20 features |
Compared with MSP430G2413IPW20, the MSP430G2513IPW20 adds a second Timer_A and USCI_B0 for expanded peripheral concurrency; versus MSP430G2553IPW20, it removes ADC10 to reduce cost and power while retaining full timer, comparator, and communication functionality.

FAQ
Does MSP430G2513IPW20 include an integrated ADC?
No, the MSP430G2513IPW20 does not include the ADC10 module. Per TI's SLAS735J datasheet Table 1 and functional block diagrams, ADC10 is exclusive to MSP430G2x53 devices (e.g., MSP430G2553), while MSP430G2x13 variants like MSP430G2513IPW20 retain the analog comparator (Comp_A+) but omit the 10-bit ADC. This distinction is explicitly noted in device family documentation and pin function tables.
What is the maximum operating frequency of MSP430G2513IPW20?
The MSP430G2513IPW20 supports a maximum CPU clock (MCLK) of 16 MHz, achieved via its digitally controlled oscillator (DCO) with factory-calibrated settings stored in information memory segment A. This frequency is confirmed in the "Basic Clock Module Configurations" section and functional block diagram of SLAS735J, and applies directly to the MSP430G2513IPW20 variant.
Can MSP430G2513IPW20 drive capacitive touch buttons?
Yes, the MSP430G2513IPW20 supports capacitive-touch sensing on all P1.x and P2.x I/O pins. Each pin includes a dedicated oscillator enable bit (P1SEL/P2SEL configuration) and software-configurable charge-transfer timing - enabling robust touch-button implementation without external components, as documented in the "Capacitive-Touch Enabled I/O Pins" feature list and port register descriptions.
Is MSP430G2513IPW20 pin-compatible with MSP430G2553IPW20?
Yes, the MSP430G2513IPW20 and MSP430G2553IPW20 share identical 20-pin TSSOP (PW20) packaging and pin mapping per TI's SLAS735J device pinout diagrams. All signal names, power, ground, and debug pins align exactly - allowing drop-in replacement where ADC10 functionality is not required, and simplifying design reuse across product variants.
What debug interface does MSP430G2513IPW20 support?
The MSP430G2513IPW20 supports Spy-Bi-Wire (SBW) debug via pins RST/NMI/SBWTDIO (Pin 16) and TEST/SBWTCK (Pin 17). This 2-wire interface is fully compatible with TI's MSP-FET and IAR/Code Composer Studio toolchains, providing full flash programming, breakpoint setting, and real-time register inspection - as specified in the "On-Chip Emulation Logic" feature list and pin function table.
