Texas Instruments MSP430G2213IN20

Overview

MSP430G2213IN20 from Texas Instruments is an ultra-low-power 16-bit RISC mixed-signal microcontroller in 20-pin PDIP packaging, featuring 2 kB flash, 256 B RAM, two 16-bit Timer_A modules with three capture/compare registers each, on-chip comparator (Comp_A+), and Universal Serial Communication Interface (USCI) supporting UART, SPI, and I²C. It operates from 1.8 V to 3.6 V and targets battery-powered sensor nodes and portable instrumentation.

For engineers reviewing the MSP430G2213IN20 datasheet, MSP430G2213IN20 pinout, MSP430G2213IN20 application, or MSP430G2213IN20 equivalent, key selection criteria include its 2 kB flash size, absence of ADC10 (distinguishing it from G2x53 variants), 20-pin PDIP package compatibility with legacy prototyping, and support for Spy-Bi-Wire debugging without external programming voltage.

Technical Context

The MSP430G2213IN20 implements a 16-bit RISC CPU with 62.5-ns instruction cycle time and constant generators for optimized code efficiency. Its clock system integrates a digitally controlled oscillator (DCO), internal very-low-power LF oscillator, and external crystal support (32 kHz), enabling sub-1 µs wake-up from LPM4 standby mode.

It features two independent 16-bit Timer_A modules (TA0 and TA1), each with three capture/compare registers and multiple clock sources (ACLK, SMCLK, TA0CLK). The USCI module provides full-duplex UART with auto-baudrate detection (LIN), IrDA encoding/decoding, synchronous SPI, and I²C master/slave capability - all without requiring ADC10 functionality.

FAQ

Does MSP430G2213IN20 include an integrated analog-to-digital converter (ADC)?

No, MSP430G2213IN20 does not include ADC10. It belongs to the G2x13 series, which omits the 10-bit ADC found in G2x53 variants. Instead, it provides the Comp_A+ module for analog signal comparison and slope A/D conversion. This makes MSP430G2213IN20 suitable for applications where threshold detection suffices and ADC resolution is not required.

What package type and pin count does MSP430G2213IN20 use?

MSP430G2213IN20 uses a 20-pin Plastic Dual In-line Package (PDIP) with 0.300-inch width. This through-hole package supports breadboard prototyping, socket-based testing, and legacy PCB assembly. Pin functions are defined in TI's SLAS735J datasheet, and the device shares pinout compatibility with other 20-pin G2x13/G2x53 variants like MSP430G2213IPW20 (TSSOP).

Can MSP430G2213IN20 be programmed and debugged without a JTAG header?

Yes, MSP430G2213IN20 supports Spy-Bi-Wire (SBW) debugging and programming using only two pins: RST/NMI/SBWTDIO (Pin 16) and TEST/SBWTCK (Pin 17). This eliminates the need for a full 4-wire JTAG interface, reducing PCB footprint and simplifying in-system programming - a key advantage for space-constrained or cost-sensitive designs using MSP430G2213IN20.

What clock sources are supported by MSP430G2213IN20?

MSP430G2213IN20 supports multiple clock sources: internal digitally controlled oscillator (DCO) calibrated up to 16 MHz, internal very-low-power LF oscillator, external 32-kHz crystal (via XIN/XOUT pins), and external digital clock source. The DCO enables sub-1 µs wake-up from LPM4, while ACLK, MCLK, and SMCLK are independently configurable for optimal power/performance trade-offs in MSP430G2213IN20 applications.

Is MSP430G2213IN20 compatible with the MSP430G2553 software ecosystem?

MSP430G2213IN20 shares the same core architecture, register map, and peripheral naming conventions as MSP430G2553, enabling significant code reuse. However, differences exist: MSP430G2213IN20 lacks ADC10 and has half the RAM (256 B vs. 512 B), so firmware must avoid ADC10 register access and manage memory accordingly. Driver libraries and HAL layers written for G2553 can be adapted for MSP430G2213IN20 with minor configuration changes.
