Product details
Overview
MSP430G2113IN20 from Texas Instruments is an ultra-low-power 16-bit RISC mixed-signal microcontroller in 20-pin PDIP packaging, featuring 16 KB flash, 256 B RAM, two 16-bit Timer_A modules, USCI_A0 (UART/SPI) and USCI_B0 (SPI/I²C), on-chip comparator, and brownout detection - deployed in battery-powered sensor nodes and portable instrumentation.
For engineers reviewing the MSP430G2113IN20 datasheet, MSP430G2113IN20 pinout, MSP430G2113IN20 application, or MSP430G2113IN20 equivalent, key selection criteria include its 20-pin PDIP package, absence of ADC10 (distinguishing it from G2x53 variants), ultra-low standby current (0.5 µA), Spy-Bi-Wire debug interface, and support for capacitive-touch I/O on up to 24 pins across P1–P3.
Technical Context
The MSP430G2113IN20 implements a 16-bit CPU with constant generators and seven addressing modes, executing instructions in 62.5 ns at 16 MHz via DCO-calibrated internal oscillator. Its clock system delivers ACLK (LF crystal or VLO), MCLK (system), and SMCLK (peripheral) with LPM0–LPM4 power modes enabling sub-µA retention.
Peripherals include two 16-bit Timer_A modules (TA0 and TA1), each with three capture/compare registers and multiple clock sources; USCI_A0 supporting UART with auto-baud LIN detection and synchronous SPI; USCI_B0 supporting SPI and I²C; and an 8-channel analog comparator (Comp_A+) usable for slope A/D conversion or signal thresholding.

FAQ
Does MSP430G2113IN20 include an integrated ADC?
No, MSP430G2113IN20 does not integrate the ADC10 module. It belongs to the G2x13 series, which omits the 10-bit analog-to-digital converter present in G2x53 variants like MSP430G2553IN20. Analog signal conditioning must be performed externally or via the on-chip comparator for slope A/D conversion.
What debug interface does MSP430G2113IN20 support?
MSP430G2113IN20 supports Spy-Bi-Wire (SBW), a two-wire variant of JTAG, using pins RST/NMI/SBWTDIO (Pin 16) and TEST/SBWTCK (Pin 17). This enables full in-system programming, real-time debugging, and flash memory access without requiring a 4-pin JTAG header.
Can MSP430G2113IN20 drive capacitive touch buttons?
Yes, MSP430G2113IN20 supports capacitive touch sensing on all port pins (P1–P3) using its built-in pin oscillators and comparator. No external RC network or dedicated touch controller is required - enabling low-cost, low-power touch interfaces directly in firmware.
What is the maximum operating frequency of MSP430G2113IN20?
MSP430G2113IN20 operates at up to 16 MHz using its digitally controlled oscillator (DCO), calibrated internally and stored in information memory segment A. The DCO stabilizes in less than 1 µs, enabling rapid transitions from LPM4 to active mode for time-critical tasks.
Is MSP430G2113IN20 pin-compatible with other 20-pin MSP430G2xx devices?
Yes, MSP430G2113IN20 shares identical 20-pin PDIP (N20) pinout with MSP430G2213IN20, MSP430G2313IN20, MSP430G2413IN20, and MSP430G2513IN20. Function mapping is consistent across the G2x13/G2x53 families, though peripheral availability (e.g., ADC10, Timer_A3) differs per variant.
