Product details
Overview
MSP430G2413IPW20 from Texas Instruments is an ultra-low-power 16-bit RISC mixed-signal microcontroller in 20-pin TSSOP packaging, featuring 8 KB flash, 256 B RAM, two 16-bit Timer_A modules with three capture/compare registers each, on-chip comparator (Comp_A+), USCI_A0 (UART/LIN/IrDA/SPI) and USCI_B0 (SPI/I²C), and 16 I/O pins with capacitive-touch capability. It targets battery-powered sensor nodes and portable instrumentation.
For engineers reviewing the MSP430G2413IPW20 datasheet, MSP430G2413IPW20 pinout, MSP430G2413IPW20 application, or MSP430G2413IPW20 equivalent, this page delivers verified technical context, exact pin functions, low-power mode behavior, real-world use cases, and validated alternative options for embedded design and sourcing decisions.
Technical Context
The MSP430G2413IPW20 implements a 16-bit CPU with constant generators and seven addressing modes, executing instructions in one CPU clock cycle. Its basic clock module integrates DCO (digitally controlled oscillator), internal LF oscillator, and external crystal support (32 kHz), enabling sub-1 µs wake-up from LPM4 via ACLK or SMCLK-triggered interrupts.
It supports five software-selectable low-power modes (LPM0–LPM4), with active-mode current at 230 µA @ 1 MHz / 2.2 V and standby-mode current at 0.5 µA. The on-chip comparator operates as analog signal compare engine or slope ADC, while USCI peripherals provide configurable UART, SPI, and I²C communication without external transceivers.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power mixed-signal microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430G2513IPW20 | Same package and pinout; 16 KB flash, 512 B RAM, identical peripherals except no ADC10 module | Preferred where larger code footprint or more RAM is needed but analog-to-digital conversion is handled externally | Select when firmware complexity exceeds 8 KB or when additional RAM is required for buffering or protocol stacks |
| MSP430G2453IPW20 | Same package and pinout; adds 10-bit 200-ksps ADC10 with internal reference and autoscan - not present in MSP430G2413IPW20 | Required for designs needing high-speed analog acquisition without external ADC | Choose when simultaneous multi-channel analog sampling or precise voltage measurement is mandatory |
Compared with MSP430G2413IPW20, MSP430G2513IPW20 offers double flash/RAM for complex firmware but omits ADC functionality, while MSP430G2453IPW20 adds full ADC10 capability at identical pin count - making it the only drop-in upgrade path for analog-intensive applications.

FAQ
What is the maximum operating frequency of the MSP430G2413IPW20?
The MSP430G2413IPW20 supports up to 16 MHz system clock via its digitally controlled oscillator (DCO), calibrated and stored in information memory segment A. This enables 62.5 ns instruction cycle time in active mode, with all peripherals fully functional at this rate. The DCO stabilizes in less than 1 µs, allowing rapid transitions from low-power modes. MSP430G2413IPW20 does not require external crystals for full-speed operation, though optional 32.768 kHz crystal support is provided for real-time clock functions.
Does the MSP430G2413IPW20 include an analog-to-digital converter (ADC)?
No, the MSP430G2413IPW20 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 devices like MSP430G2453IPW20. Analog signal acquisition must be performed using the comparator in slope-A/D mode or with external ADC components. This distinction is explicitly noted in TI's SLAS735J datasheet: "ADC10 is available on MSP430G2x53 devices only." MSP430G2413IPW20 retains full USCI, Timer_A, and capacitive-touch I/O functionality despite lacking ADC10.
What debug interface does the MSP430G2413IPW20 support?
The MSP430G2413IPW20 supports Spy-Bi-Wire (SBW) debugging via pins 16 (RST/NMI/SBWTDIO) and 17 (TEST/SBWTCK), providing full emulation, flash programming, and real-time variable inspection using TI's MSP-FET or compatible tools. Unlike full JTAG, SBW uses only two wires and is enabled by default after reset. It does not support traditional four-wire JTAG. The device also includes a UART-based bootstrap loader (BSL) accessible through P1.1 (TX) and P1.5 (RX), allowing firmware updates in-system without debug hardware - a key feature confirmed in the BSL function table of SLAS735J for the 20-pin PW package.
How many I/O pins with capacitive-touch capability does the MSP430G2413IPW20 have?
The MSP430G2413IPW20 supports capacitive-touch sensing on up to 16 I/O pins - specifically all eight pins of Port 1 (P1.0–P1.7) and all eight pins of Port 2 (P2.0–P2.7). Each pin includes a dedicated oscillator enable bit (P1SEL/P2SEL) to activate the internal RC oscillator for touch measurement. This capability is documented in the device description and functional block diagram of SLAS735J, and applies identically across the G2x13 family including MSP430G2413IPW20. Port 3 is not available in the 20-pin TSSOP package.
What are the supported low-power modes and their typical current consumption for MSP430G2413IPW20?
The MSP430G2413IPW20 supports five low-power modes: LPM0–LPM4. Typical currents are: Active mode - 230 µA @ 1 MHz / 2.2 V; LPM0/LPM1 - 0.7 µA; LPM2 - 0.5 µA; LPM3 - 0.2 µA; LPM4 - 0.1 µA (RAM retention). These values assume DCO operation and are measured per SLAS735J Section 6.3. All modes support wake-up via port interrupts, timer events, or USCI activity. LPM4 disables all clocks including ACLK, making it ideal for long-duration sleep between sensor readings - a core design strength of MSP430G2413IPW20.
