Product details
Overview
MSP430G2153IPW28R from Texas Instruments is an ultra-low-power 16-bit RISC mixed-signal microcontroller featuring 1 kB flash, 256 B RAM, a 10-bit 200-ksps ADC with internal reference and autoscan, two 16-bit Timer_A modules, USCI_A0 (UART/LIN/IrDA/SPI) and USCI_B0 (SPI/I²C), and up to 24 capacitive-touch-enabled I/O pins in a 28-pin TSSOP package. It targets battery-powered sensor nodes and portable measurement systems.
For engineers reviewing the MSP430G2153IPW28R datasheet, MSP430G2153IPW28R pinout, MSP430G2153IPW28R application, or MSP430G2153IPW28R equivalent, key selection criteria include its 1 kB flash/256 B RAM memory footprint, 28-pin TSSOP package with P3 port availability, integrated ADC10 (not present in G2x13 variants), ultra-low standby current (0.5 µA), and Spy-Bi-Wire debug interface compatibility.
Technical Context
The MSP430G2153IPW28R 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 a digitally controlled oscillator (DCO), 32-kHz crystal support, and internal LF oscillator-enabling sub-1-µs wake-up from LPM4.
It features dual USCI modules: USCI_A0 supports UART with auto-baudrate detection (LIN), IrDA encoding/decoding, and synchronous SPI; USCI_B0 supports SPI and I²C. The on-chip comparator (Comp_A+) provides analog signal compare or slope A/D conversion, while Timer_A modules support capture/compare with three registers each.

FAQ
What is the maximum ADC10 sampling rate supported by the MSP430G2153IPW28R?
The MSP430G2153IPW28R supports a maximum ADC10 sampling rate of 200 ksps (kilo-samples per second) with internal reference and autoscan enabled. This rate is achievable when ADC10CLK is sourced from the DCO at ≥5 MHz and conversion timing parameters (ADC10SHTx, ADC10DIV) are configured for minimum sample-and-hold duration. Real-world throughput may be lower depending on software overhead and channel count.
Does the MSP430G2153IPW28R support hardware UART auto-baudrate detection?
Yes, the MSP430G2153IPW28R's USCI_A0 module supports hardware auto-baudrate detection in UART mode, specifically designed for LIN bus compliance. It measures the break-field duration and synchronizes to incoming data frames without CPU intervention-enabling robust communication in noisy automotive or industrial environments.
How many I/O pins on the MSP430G2153IPW28R support capacitive touch sensing?
The MSP430G2153IPW28R supports capacitive touch sensing on up to 24 I/O pins-spanning all bits of Ports P1, P2, and P3. Each pin has an individually configurable oscillator enable bit (PxIES.x), allowing implementation of touch buttons, sliders, or proximity detection using only the MCU's built-in resources and no external components.
What debug interface does the MSP430G2153IPW28R use, and how many pins are required?
The MSP430G2153IPW28R uses the Spy-Bi-Wire (SBW) interface for debugging and programming, requiring only two pins: SBWTDIO (Pin 24) and SBWTCK (Pin 25). This 2-wire JTAG variant reduces PCB routing complexity compared to full 4-wire JTAG while maintaining full flash programming, breakpoint, and register access capabilities.
Is the MSP430G2153IPW28R pin-compatible with other devices in the MSP430G2x53 family?
Yes, the MSP430G2153IPW28R is pin-compatible with all other 28-pin TSSOP variants in the MSP430G2x53 family-including MSP430G2253IPW28, MSP430G2353IPW28, MSP430G2453IPW28, and MSP430G2553IPW28-sharing identical pinout, electrical characteristics, and peripheral mapping. Firmware and layout can be reused across these variants by adjusting flash/RAM initialization and peripheral enable settings.
