Product details
Overview
MSP430G2153IN20 from Texas Instruments is an ultra-low-power 16-bit RISC mixed-signal microcontroller in 20-pin PDIP 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 - designed for battery-powered sensor nodes and portable instrumentation.
For engineers reviewing the MSP430G2153IN20 datasheet, MSP430G2153IN20 pinout, MSP430G2153IN20 application, or MSP430G2153IN20 equivalent, key selection criteria include its 1.8–3.6 V supply range, sub-1 µs wake-up from standby mode, integrated USCI_A0 (UART/SPI/IrDA), absence of ADC10 (distinguishing it from G2x53 variants), and 20-pin PDIP compatibility with legacy prototyping workflows.
Technical Context
The MSP430G2153IN20 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), internal LF oscillator, and external crystal support (32 kHz), enabling five software-selectable low-power modes including LPM4 with 0.1 µA off-mode current.
Peripherals are memory-mapped and accessible via all CPU instructions. The device includes two USCI modules: USCI_A0 supports UART (with auto-baud/LIN), IrDA, and synchronous SPI; USCI_B0 supports SPI and I²C. Port P1 and P2 provide eight I/O pins each with individually configurable pullup/pulldown resistors and interrupt capability - but no Port P3 (absent in 20-pin packages).
Key Specifications

Pinout & Package
Package: 20-pin PDIP (N20), 0.3-inch width, through-hole mounting compatible with breadboards and legacy PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 DVCC | Digital power supply | Primary 1.8–3.6 V digital rail; requires local 0.1 µF decoupling |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430G2213IN20 | Same package and core, but 2 KB flash and 256 B RAM - no BSL or USCI_B0 | Limited to simpler firmware; lacks I²C/SPI slave capability and bootloader | Select when code size ≤2 KB and I²C connectivity is unnecessary |
| MSP430G2131IN20 | 2 KB flash, 128 B RAM, no USCI modules - only basic Timer_A and comparator | No serial communication; suitable only for pure GPIO/timer/comparator tasks | Select for cost-sensitive, non-communicating sensor endpoints where UART/I²C is omitted |
Compared with MSP430G2213IN20 and MSP430G2131IN20, the MSP430G2153IN20 delivers optimal balance of memory headroom (16 KB), dual-USCI flexibility, and PDIP accessibility - making it the preferred choice for upgradable sensor nodes requiring field firmware updates via UART.

FAQ
Does the MSP430G2153IN20 include an analog-to-digital converter (ADC)?
No, the MSP430G2153IN20 does not include the ADC10 module. This is explicitly confirmed in the datasheet: "NOTE: ADC10 is available on MSP430G2x53 devices only." The MSP430G2153IN20 belongs to the G2x13 series, which omits the 10-bit ADC but retains the 8-channel analog comparator (Comp_A+) for threshold-based signal conditioning. For ADC functionality, consider the pin-compatible MSP430G2553IN20.
What debug interface does the MSP430G2153IN20 support?
The MSP430G2153IN20 supports Spy-Bi-Wire (SBW) debugging using pins 16 (RST/NMI/SBWTDIO) and 17 (TEST/SBWTCK). It does not support full 4-wire JTAG. SBW is a two-wire variant that shares the reset line for bidirectional data transfer, reducing PCB routing complexity while maintaining full flash programming and real-time debugging capability via TI's MSP-FET or compatible tools.
Can the MSP430G2153IN20 drive capacitive touch buttons?
Yes, the MSP430G2153IN20 supports capacitive touch sensing on all P1.x pins via its integrated pin-oscillator circuitry. Enabling the PxIES and PxSEL bits configures the pin for relaxation oscillator operation, allowing direct measurement of touch-induced capacitance change without external components. This capability is documented in the MSP430x2xx Family User's Guide (SLAU144) and confirmed in the device-specific datasheet section on Digital I/O.
What is the maximum operating frequency of the MSP430G2153IN20 DCO?
The digitally controlled oscillator (DCO) in the MSP430G2153IN20 is factory-calibrated up to 16 MHz across multiple RSEL and DCO settings. Calibration constants for 1 MHz, 8 MHz, 12 MHz, and 16 MHz are stored in information memory segment A. The DCO stabilizes in less than 1 µs, enabling rapid transitions from LPM3/LPM4 into active mode at full speed - a key enabler for duty-cycled sensor applications.
Is the MSP430G2153IN20 pin-compatible with other 20-pin MSP430G2xx devices?
Yes, the MSP430G2153IN20 shares identical pinout and electrical characteristics with other 20-pin PDIP MSP430G2xx devices including MSP430G2213IN20, MSP430G2253IN20, and MSP430G2413IN20. All use the N20 package with matching pin functions per Table 2 of SLAS735J. This allows hardware reuse across firmware variants - for example, upgrading from MSP430G2153IN20 to MSP430G2553IN20 adds ADC10 and doubles RAM without PCB changes.
