Texas Instruments MSP430G2213IPW20

Overview

MSP430G2213IPW20 from Texas Instruments is an ultra-low-power 16-bit RISC mixed-signal microcontroller in 20-pin TSSOP packaging, featuring 2 kB flash, 256 B RAM, two 16-bit Timer_A modules with three capture/compare registers each, on-chip comparator, USCI_A0 (UART/LIN/IrDA/SPI), USCI_B0 (SPI/I²C), 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 MSP430G2213IPW20 datasheet, MSP430G2213IPW20 pinout, MSP430G2213IPW20 application, or MSP430G2213IPW20 equivalent, key selection criteria include its 2 kB flash capacity, absence of integrated ADC10 (distinguishing it from G2x53 variants), 20-pin TSSOP package compatibility, and support for Spy-Bi-Wire programming without external voltage.

Technical Context

The MSP430G2213IPW20 implements a 16-bit CPU with seven addressing modes and register-to-register execution in one MCLK cycle. Its clock system integrates a digitally controlled oscillator (DCO) calibrated to 1 MHz, 8 MHz, 12 MHz, and 16 MHz, plus internal LF and external 32-kHz crystal support - enabling sub-1 µs wake-up from LPM4.

Peripherals include two independent 16-bit Timer_A modules (TA0 and TA1), each with three capture/compare registers and multiple clock sources (ACLK, SMCLK, TAxCLK); USCI_A0 supporting UART auto-baud detection (LIN), IrDA encoding/decoding, and synchronous SPI; and USCI_B0 supporting master/slave SPI and I²C bus communication - all accessible via dedicated port pins with programmable pullup/pulldown resistors.

FAQ

Does the MSP430G2213IPW20 include an integrated analog-to-digital converter (ADC)?

No, the MSP430G2213IPW20 does not include the ADC10 module. This is explicitly confirmed in TI's SLAS735J datasheet: "NOTE: ADC10 is available on MSP430G2x53 devices only." The MSP430G2213IPW20 belongs to the G2x13 series, which omits the 10-bit ADC but retains the 8-channel Comparator_A+ for analog threshold detection. Designers requiring ADC functionality must select an MSP430G2x53 variant such as MSP430G2253IPW20.

What is the maximum operating frequency of the MSP430G2213IPW20 DCO?

The digitally controlled oscillator (DCO) in the MSP430G2213IPW20 is factory-calibrated to four nominal frequencies: 1 MHz, 8 MHz, 12 MHz, and 16 MHz. These calibration values are stored in information memory segment A. While the DCO can be tuned between these points using MODx and DCOx bits, the maximum guaranteed operating frequency is 16 MHz at VCC ≥ 2.2 V, as specified in the "DCO Characteristics" section of SLAS735J.

Can the MSP430G2213IPW20 be programmed using only the Spy-Bi-Wire interface?

Yes, the MSP430G2213IPW20 supports full flash programming and debugging via the 2-wire Spy-Bi-Wire (SBW) interface using pins RST/NMI/SBWTDIO (Pin 16) and TEST/SBWTCK (Pin 17). No external programming voltage is required - SBW operates from the device's DVCC supply. This capability is enabled by on-chip emulation logic and does not require JTAG header footprint or additional circuitry.

How many I/O pins on the MSP430G2213IPW20 support capacitive touch sensing?

The MSP430G2213IPW20 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). This is achieved using the integrated pin-oscillator feature, where each pin's parasitic capacitance modulates an internal oscillator frequency - enabling touch detection without external components or dedicated ADC channels.

Is the MSP430G2213IPW20 pin-compatible with other devices in the MSP430G2xx family?

The MSP430G2213IPW20 is pin-compatible with all 20-pin TSSOP variants in the MSP430G2xx family, including MSP430G2113IPW20, MSP430G2313IPW20, MSP430G2413IPW20, and MSP430G2513IPW20. All share identical PW20 pinout, power/ground placement, and core peripheral mapping. However, peripheral availability (e.g., USCI_B0, comparator, flash size) varies - so firmware and schematic design must verify functional compatibility beyond pin alignment.
