Product details
Overview
MSP430G2513IN20 from Texas Instruments is an ultra-low-power 16-bit RISC mixed-signal microcontroller in 20-pin PDIP 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), on-chip comparator, and Spy-Bi-Wire debug interface - deployed in battery-powered sensor nodes and portable instrumentation.
For engineers reviewing the MSP430G2513IN20 datasheet, MSP430G2513IN20 pinout, MSP430G2513IN20 application, or MSP430G2513IN20 equivalent, key selection criteria include its 20-pin PDIP package compatibility with legacy through-hole prototyping, absence of ADC10 (distinguishing it from G2x53 variants), ultra-low standby current (0.5 µA), and integrated capacitive-touch I/O capability across up to 24 pins.
Technical Context
The MSP430G2513IN20 implements a 16-bit CPU with constant generators and seven addressing modes, executing instructions in 62.5 ns at 16 MHz. Its clock system integrates a digitally controlled oscillator (DCO), internal LF oscillator, and external crystal support (32 kHz), enabling sub-1 µs wake-up from LPM4.
It supports five low-power modes (LPM0–LPM4), with active-mode current specified at 230 µA @ 1 MHz / 2.2 V. The USCI_A0 module delivers enhanced UART with auto-baudrate detection for LIN, IrDA encoding/decoding, and synchronous SPI; USCI_B0 provides SPI and I²C master/slave operation.

Applications
| Smart Meter Sensor Interface | Portable Medical Monitor |
|---|---|
Use Scenario: Reads temperature, pressure, and humidity sensors in utility meters using polling or timer-triggered sampling. IC Role / Device Role / Timing Role: Central controller managing sensor excitation, analog comparison, serial communication to RF module, and low-power state transitions. Use Value: Sub-µA standby current extends battery life beyond 10 years; USCI_B0 I²C directly interfaces with digital sensors (e.g., TMP102, BMP280). | Use Scenario: Captures ECG lead signals via analog front-end, performs real-time thresholding, and transmits alerts over UART to Bluetooth module. IC Role / Device Role / Timing Role: Analog comparator-based event detector with precise timing control for heartbeat interval measurement using Timer_A. Use Value: Comparator_A+ with programmable hysteresis rejects noise without software overhead; 1 µs wake-up ensures no pulse is missed during sleep cycles. |
| Industrial Control Panel | Capacitive Touch Remote |
Use Scenario: Monitors discrete inputs (limit switches, emergency stops) and drives LED indicators and relay drivers in factory HMIs. IC Role / Device Role / Timing Role: Real-time I/O manager with edge-triggered interrupts on P1/P2, configurable pullup/down resistors, and deterministic response latency. Use Value: Independent per-pin interrupt configuration avoids polling overhead; 20-pin PDIP simplifies replacement in existing panel PCBs. | Use Scenario: Detects finger proximity on copper pads and transmits button press events via UART to host MCU. IC Role / Device Role / Timing Role: Capacitive-touch engine using built-in oscillator and charge-transfer measurement on P1.x/P2.x pins. Use Value: No external RC network required - touch sensitivity tuned in firmware via TA0/TA1 timing and comparator thresholds. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430G2413IN20 | 8 KB flash, 256 B RAM, same 20-pin PDIP package and peripheral set (no ADC10) | Lower memory capacity suits simpler control tasks with minimal firmware footprint | Select when application requires <8 KB code space and lower cost is prioritized over future firmware scalability |
| MSP430G2553IPW20 | 16 KB flash, 512 B RAM, includes 10-bit ADC10 with 8 channels; 20-pin TSSOP package | Enables analog sensor digitization without external ADC; surface-mount only | Select when ADC functionality is required and board design supports TSSOP reflow assembly |

FAQ
Does the MSP430G2513IN20 include an analog-to-digital converter (ADC)?
No, the MSP430G2513IN20 does not include the ADC10 module. It belongs to the G2x13 series, which omits the 10-bit ADC present in G2x53 variants like MSP430G2553. Its analog capability relies solely on the 8-channel Comparator_A+ for threshold detection and slope A/D conversion. This distinction is confirmed in Table 1 and the "NOTE" sections of the SLAS735J datasheet.
What is the maximum operating frequency of the MSP430G2513IN20?
The MSP430G2513IN20 supports internal DCO frequencies up to 16 MHz, with calibrated settings stored in information memory segment A. The CPU executes instructions at 62.5-ns cycle time at this rate, and the device maintains timing specifications across its full 1.8–3.6 V supply range per the SLAS735J datasheet's DC characteristics table.
Can the MSP430G2513IN20 be programmed using the Spy-Bi-Wire interface?
Yes, the MSP430G2513IN20 supports programming and debugging via the two-wire Spy-Bi-Wire interface using pins RST/NMI/SBWTDIO (Pin 16) and TEST/SBWTCK (Pin 17). This eliminates the need for a full 4-wire JTAG header and is fully supported by TI's MSP-FET and open-source tools like naken_asm and mspdebug.
Is the MSP430G2513IN20 pin-compatible with other 20-pin MSP430G2xx devices?
Yes, the MSP430G2513IN20 shares identical pinout and electrical characteristics with other 20-pin PDIP MSP430G2xx devices including MSP430G2413IN20 and MSP430G2213IN20, as defined in the "Device Pinout, MSP430G2x13 and MSP430G2x53, 20-Pin Devices" section of SLAS735J. Function mapping per pin is consistent across the family.
What low-power modes are supported by the MSP430G2513IN20?
The MSP430G2513IN20 supports six operating modes: Active Mode (AM) and five software-selectable low-power modes (LPM0–LPM4). LPM4 achieves 0.1 µA off-mode current with RAM retention, while LPM3 draws 0.2 µA with ACLK active - enabling multi-year operation on coin-cell batteries in intermittent-sensing applications.
