Texas Instruments MSP430G2413IN20

Overview

MSP430G2413IN20 from Texas Instruments is an ultra-low-power 16-bit RISC mixed-signal microcontroller in 20-pin PDIP packaging, featuring 8 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 up to 16 capacitive-touch-enabled I/O pins. It targets battery-powered sensor nodes and portable instrumentation requiring sub-1 µs wake-up and <0.5 µA standby current.

For engineers reviewing the MSP430G2413IN20 datasheet, MSP430G2413IN20 pinout, MSP430G2413IN20 application, or MSP430G2413IN20 equivalent, key selection criteria include its 8 KB flash/512 B RAM configuration, absence of integrated ADC10 (distinguishing it from G2x53 variants), 20-pin PDIP package compatibility with legacy through-hole prototyping, and verified Spy-Bi-Wire debug interface support.

Technical Context

The MSP430G2413IN20 implements a 16-bit CPU with seven addressing modes and 51 instructions, executing register-to-register operations in one CPU clock cycle. Its basic clock module integrates a digitally controlled oscillator (DCO) calibrated for 1–16 MHz operation, internal LF oscillator, and external crystal support (32 kHz), enabling five low-power modes including LPM4 with 0.1 µA off-mode current.

Peripheral interconnect uses unified data/address/control buses, allowing full instruction set access to all modules. The USCI_A0 supports auto-baudrate detection for LIN communication and IrDA encoding/decoding, while USCI_B0 provides hardware I²C master/slave capability and synchronous SPI with independent clock polarity and phase control.

FAQ

What is the maximum operating frequency of the MSP430G2413IN20?

The MSP430G2413IN20 supports a maximum DCO-sourced MCLK frequency of 16 MHz, with internal calibration data stored in information memory segment A for 1 MHz, 8 MHz, 12 MHz, and 16 MHz settings. This enables deterministic timing for real-time tasks such as UART communication at 115.2 kbps or PWM generation at 100 kHz without external crystal dependency.

Does the MSP430G2413IN20 include an analog-to-digital converter (ADC)?

No, the MSP430G2413IN20 does not include the ADC10 module. It belongs to the G2x13 series, which omits the 10-bit ADC present in G2x53 devices. Analog signal acquisition must be performed externally or via the on-chip comparator's slope A/D method, as confirmed in Table 1 and the "NOTE: ADC10 is available on MSP430G2x53 devices only" statement in the datasheet.

Which debug interface does the MSP430G2413IN20 support?

The MSP430G2413IN20 supports Spy-Bi-Wire (SBW) debug via pins RST/NMI/SBWTDIO (Pin 16) and TEST/SBWTCK (Pin 17). This 2-wire interface enables full-speed debugging, flash programming, and real-time register inspection using TI's MSP-FET or compatible tools-without requiring a full 4-wire JTAG header.

What are the key differences between MSP430G2413IN20 and MSP430G2453IN20?

The MSP430G2413IN20 and MSP430G2453IN20 share identical 20-pin PDIP packaging, 8 KB flash, and 512 B RAM, but MSP430G2453IN20 integrates the ADC10 module (10-bit, 200 ksps) while MSP430G2413IN20 does not. Both support USCI_A0/B0, Timer_A, and comparator functions, making the G2453 a functional superset where analog digitization is required.

Can the MSP430G2413IN20 drive capacitive touch buttons directly?

Yes, the MSP430G2413IN20 supports capacitive touch sensing on up to 16 I/O pins using its integrated RC oscillator and built-in comparator. Each pin can be configured with programmable oscillator enable and hysteresis control, enabling robust touch detection without external components-confirmed by the "Up to 24 Capacitive-Touch Enabled I/O Pins" feature and functional block diagram in the datasheet.
