Product details
Overview
MSP430G2353IPW28R from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller featuring 4 KB flash, 256 B RAM, a 10-bit 200-ksps ADC with internal reference and autoscan, two 16-bit Timer_A modules with three capture/compare registers each, and USCI_A0 (UART/LIN/IrDA/SPI) + USCI_B0 (SPI/I²C). It operates from 1.8 V to 3.6 V and targets battery-powered sensor nodes and portable instrumentation.
For engineers reviewing the MSP430G2353IPW28R datasheet, MSP430G2353IPW28R pinout, MSP430G2353IPW28R application, or MSP430G2353IPW28R equivalent, key selection criteria include its 28-pin TSSOP package, ADC10 channel count (8), standby current (0.5 µA), capacitive-touch I/O support (up to 24 pins), and Spy-Bi-Wire debug interface compatibility.
Technical Context
The MSP430G2353IPW28R implements a 16-bit RISC CPU with 62.5-ns instruction cycle time, digitally controlled oscillator (DCO) enabling sub-1-µs wake-up from LPM4, and dual USCI modules supporting asynchronous UART with auto-baud detection and synchronous SPI/I²C. Its clock system integrates ACLK (32-kHz crystal or LF oscillator), MCLK (DCO-driven), and SMCLK (peripheral clock).
It features a dedicated analog comparator (Comp_A+) with eight input channels, brownout detector, on-chip BSL for UART-based in-system programming, and five programmable low-power modes (LPM0–LPM4). Port P3 is available only on 28-pin and 32-pin packages, confirming full pin functionality for this TSSOP variant.

FAQ
What is the maximum ADC10 sampling rate supported by the MSP430G2353IPW28R?
The MSP430G2353IPW28R supports a maximum ADC10 sampling rate of 200 ksps (kilo-samples per second) with internal reference and sample-and-hold enabled. This specification is confirmed in the SLAS735J datasheet Section 1, and applies directly to the MSP430G2353IPW28R as a member of the MSP430G2x53 family. The ADC10 module achieves this rate using its dedicated 5-MHz ADC10CLK derived from the DCO or external source.
Does the MSP430G2353IPW28R include hardware support for capacitive touch sensing?
Yes, the MSP430G2353IPW28R includes hardware support for capacitive touch sensing on up to 24 I/O pins. Each port pin (P1.x, P2.x, P3.x) has an individually programmable pin oscillator enable bit, allowing direct implementation of charge-transfer touch detection without external components. This capability is explicitly documented in the SLAS735J datasheet Features section and functional block diagram for MSP430G2x53 devices.
What debug interface does the MSP430G2353IPW28R use, and what pins are required?
The MSP430G2353IPW28R uses the Spy-Bi-Wire (SBW) interface for on-chip emulation and programming. It requires two pins: SBWTDIO (Pin 24, shared with RST/NMI) and SBWTCK (Pin 25, shared with TEST). This 2-wire interface is fully compatible with TI's MSP-FET and LaunchPad development tools, and is confirmed in the SLAS735J datasheet Section "On-Chip Emulation Logic With Spy-Bi-Wire Interface".
Is the MSP430G2353IPW28R pin-compatible with other devices in the MSP430G2x53 family?
Yes, the MSP430G2353IPW28R is pin-compatible with other 28-pin TSSOP variants in the MSP430G2x53 family-including MSP430G2453IPW28 and MSP430G2553IPW28-as confirmed by identical PW28 pinout diagrams and terminal function tables in SLAS735J. All share the same 28-pin mapping, signal definitions, and electrical characteristics, enabling drop-in replacement where memory or peripheral requirements align.
What is the minimum supply voltage for reliable operation of the MSP430G2353IPW28R?
The MSP430G2353IPW28R operates reliably from 1.8 V to 3.6 V, as specified in the Absolute Maximum Ratings and Electrical Characteristics sections of SLAS735J. At 1.8 V, all core functions-including 16-MHz DCO operation, ADC10 conversion, and USCI communication-are fully functional, enabling compatibility with single-cell lithium batteries and energy-harvesting systems.
