Product details
Overview
MSP430G2153IRHB32T from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller featuring 16 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 I/O pins. It operates from 1.8 V to 3.6 V and targets battery-powered sensor nodes and portable measurement systems.
For engineers reviewing the MSP430G2153IRHB32T datasheet, MSP430G2153IRHB32T pinout, MSP430G2153IRHB32T application, or MSP430G2153IRHB32T equivalent, key selection criteria include its QFN-32 package, integrated ADC10 channel count, standby current of 0.5 µA, Spy-Bi-Wire debug interface, and absence of built-in BSL in this variant per device family documentation.
Technical Context
The MSP430G2153IRHB32T implements a 16-bit RISC CPU with 62.5-ns instruction cycle time and five software-selectable low-power modes, enabling sub-1-µs wake-up from standby. Its clock system integrates a digitally controlled oscillator (DCO), internal LF oscillator, and external crystal support (32 kHz), delivering MCLK, SMCLK, and ACLK for independent peripheral timing.
Peripherals include two 16-bit Timer_A modules (TA0 and TA1), each with three capture/compare registers; a comparator_A+ with eight input channels; and dual USCI modules supporting asynchronous UART, synchronous SPI, and I²C protocols. The ADC10 supports up to eight analog inputs with internal reference, sample-and-hold, and autoscan-confirmed for MSP430G2x53 series including this part.

FAQ
Does the MSP430G2153IRHB32T include a built-in bootloader (BSL)?
No, the MSP430G2153IRHB32T does not include a factory-programmed bootstrap loader (BSL). While BSL functionality is present in some MSP430G2x13 devices, TI documentation confirms BSL is omitted in the G2153 variant. Firmware updates require Spy-Bi-Wire programming via JTAG interface. The MSP430G2153IRHB32T relies on external tools like MSP-FET for flash programming and debugging.
What is the maximum ADC10 sampling rate supported by the MSP430G2153IRHB32T?
The MSP430G2153IRHB32T supports a maximum ADC10 sampling rate of 200 ksps (kilo-samples per second) when using the internal reference and configured for single-channel conversions. This rate is achievable at full 10-bit resolution and is specified under typical conditions (VCC = 3.0 V, TA = 25°C). Autoscan across multiple channels reduces effective throughput proportionally.
Can the MSP430G2153IRHB32T operate from a single 1.8-V supply?
Yes, the MSP430G2153IRHB32T is fully specified to operate across a supply range of 1.8 V to 3.6 V. At 1.8 V, all core functions-including 16-bit CPU execution, ADC10 conversion, USCI communication, and Timer_A operation-remain functional per the SLAS735J datasheet. Active current increases slightly versus higher voltages, but ultra-low-power modes (0.5 µA standby) remain guaranteed.
How many I/O pins on the MSP430G2153IRHB32T support capacitive touch sensing?
The MSP430G2153IRHB32T supports capacitive touch sensing on up to 24 I/O pins-specifically all P1.x, P2.x, and P3.x pins (8 + 8 + 8 = 24). Each pin includes an individually programmable pin oscillator enable bit, allowing low-cost, RC-free touch button or slider implementation without external components. This capability is confirmed for the MSP430G2x13/G2x53 families in the device description.
Is the MSP430G2153IRHB32T pin-compatible with other RHB32-packaged MSP430G2x53 devices?
Yes, the MSP430G2153IRHB32T is pin-compatible with all other MSP430G2x53 devices in the 32-pin QFN (RHB) package-including MSP430G2253IRHB32, MSP430G2353IRHB32, MSP430G2453IRHB32, and MSP430G2553IRHB32. Pin functions, electrical characteristics, and physical layout match exactly; only flash size, RAM size, and ADC channel count differ between variants within the family.
