Product details
Overview
MSP430G2153IPW20R from Texas Instruments is an ultra-low-power 16-bit RISC mixed-signal microcontroller in 20-pin TSSOP packaging, featuring 16 KB flash, 256 B RAM, one 16-bit Timer_A with three capture/compare registers, on-chip comparator, and Spy-Bi-Wire debug interface - deployed in battery-powered sensor nodes and portable instrumentation.
For engineers reviewing the MSP430G2153IPW20R datasheet, MSP430G2153IPW20R pinout, MSP430G2153IPW20R application, or MSP430G2153IPW20R equivalent, key selection criteria include ADC absence (G2x13 family), 20-pin I/O count, 1.8–3.6 V supply range, sub-1 µs wake-up from LPM4, and USCI_A0/USCI_B0 serial peripheral support.
Technical Context
The MSP430G2153IPW20R implements a 16-bit CPU with constant generators and seven addressing modes, executing instructions in 62.5 ns at 16 MHz. Its clock system integrates DCO, LF oscillator, and external crystal support (XIN/XOUT on P2.6/P2.7), enabling ACLK, MCLK, and SMCLK generation with programmable division.
It supports five low-power modes (LPM0–LPM4), with LPM4 drawing only 0.1 µA (RAM retention) and wake-up in under 1 µs via interrupt. The device lacks ADC10 - confirmed by Table 1 and "ADC10 is available on MSP430G2x53 devices only" notes - distinguishing it from G2x53 variants.

FAQ
Does MSP430G2153IPW20R include an analog-to-digital converter (ADC)?
No, MSP430G2153IPW20R does not include ADC10. It belongs to the MSP430G2x13 series, which omits the 10-bit ADC module present in G2x53 variants. Designers requiring analog digitization must use external ADCs or select G2x53-family parts like MSP430G2553IPW20R. The comparator (Comp_A+) remains functional for threshold detection and slope A/D conversion.
What is the maximum operating frequency of MSP430G2153IPW20R?
The MSP430G2153IPW20R supports a maximum system clock (MCLK) of 16 MHz, achieved via its digitally controlled oscillator (DCO) with factory-calibrated settings stored in information memory segment A. Internal frequency calibration ensures stable operation across voltage and temperature without external crystal dependency.
Can MSP430G2153IPW20R be programmed in-circuit without a dedicated JTAG emulator?
Yes, MSP430G2153IPW20R supports in-system programming via its integrated bootstrap loader (BSL), accessible through UART on P1.1 (RX) and P1.5 (TX). No external JTAG hardware is required for firmware updates - only a UART-to-USB bridge and TI's BSL Scripter utility are needed to reprogram flash memory in the field.
How many I/O pins does MSP430G2153IPW20R provide, and are they all individually configurable?
MSP430G2153IPW20R provides 16 general-purpose I/O pins across Ports P1 and P2 (P1.0–P1.7, P2.0–P2.7), all individually configurable as input, output, or peripheral function. Each pin supports programmable pullup/pulldown resistors and optional capacitive-touch oscillator enable - confirmed in the device pinout table and functional block diagram.
Is MSP430G2153IPW20R pin-compatible with other 20-pin MSP430G2xx devices?
Yes, MSP430G2153IPW20R shares identical 20-pin TSSOP (PW20) packaging and pinout with MSP430G2213IPW20R, MSP430G2313IPW20R, and MSP430G2413IPW20R. Signal mapping for DVCC, DVSS, RST/NMI, TEST/SBWTCK, XIN/XOUT, and all P1/P2 I/O is consistent - enabling drop-in replacement within the G2x13 family for flash/RAM scaling.
