Product details
Overview
MSP430G2213IPW20R from Texas Instruments is an ultra-low-power 16-bit RISC mixed-signal microcontroller in 20-pin TSSOP package, 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 MSP430G2213IPW20R datasheet, MSP430G2213IPW20R pinout, MSP430G2213IPW20R application, or MSP430G2213IPW20R equivalent, key selection criteria include its 2 kB flash size, absence of ADC10 (distinguishing it from G2x53 variants), 20-pin TSSOP footprint, USCI dual-channel support, and verified sub-1 µs wake-up from LPM4 standby mode.
Technical Context
The MSP430G2213IPW20R implements a 16-bit CPU with seven addressing modes and 51-instruction set, paired with a basic clock module offering DCO (calibrated up to 16 MHz), VLO, and external crystal support. Its interrupt system includes 18 maskable sources mapped to 16 vectors, with priority-based servicing and dedicated flags for USCI_A0/USCI_B0, Timer_A, Comparator_A+, and port interrupts.
It integrates Spy-Bi-Wire debug interface, programmable pullup/pulldown resistors on all I/O pins, capacitive-touch enable bits per P1/P2 pin, and brownout protection. The device lacks ADC10 hardware-confirmed across all G2x13 family members-and relies solely on Comp_A+ for analog signal comparison or slope A/D conversion.

FAQ
Does MSP430G2213IPW20R include an analog-to-digital converter (ADC)?
No, the MSP430G2213IPW20R does not include ADC10 hardware. It belongs to the G2x13 series, which omits the 10-bit ADC module present in G2x53 variants. Analog signal acquisition must be implemented using the on-chip Comp_A+ in slope A/D mode or external ADCs interfaced via USCI.
What is the maximum operating frequency of MSP430G2213IPW20R?
The MSP430G2213IPW20R supports a digitally controlled oscillator (DCO) calibrated up to 16 MHz, confirmed by factory-stored calibration data in information memory segment A. This allows full-speed execution at 16 MHz in active mode with 62.5-ns instruction cycle time.
Can MSP430G2213IPW20R be programmed in-system without a JTAG emulator?
Yes, the MSP430G2213IPW20R includes a UART-based bootstrap loader (BSL) accessible via P1.1 (TX) and P1.5 (RX). With proper password handling and voltage conditions, firmware updates can be performed in-system using only a UART interface - no JTAG or Spy-Bi-Wire hardware required.
How many I/O pins does MSP430G2213IPW20R provide, and are they all configurable?
The MSP430G2213IPW20R provides 16 usable I/O pins (P1.0–P1.7, P2.0–P2.7) in its 20-pin TSSOP package. All pins are individually configurable as digital inputs/outputs with programmable pullup/pulldown resistors and optional capacitive-touch enable - no fixed-function-only pins exist.
Is MSP430G2213IPW20R pin-compatible with other devices in the MSP430G2xx family?
The MSP430G2213IPW20R shares identical 20-pin TSSOP (PW20) packaging and pinout with MSP430G2113IPW20R, MSP430G2313IPW20R, MSP430G2413IPW20R, and MSP430G2513IPW20R. However, peripheral differences (e.g., flash size, RAM, Timer_A count) require firmware validation - hardware layout is interchangeable within the G2x13/G2x53 PW20 group.
