Product details
Overview
MSP430G2153IPW28 from Texas Instruments is an ultra-low-power 16-bit RISC mixed-signal microcontroller in 28-pin TSSOP packaging, featuring 16 KB flash, 256 B RAM, one 16-bit Timer_A with three capture/compare registers, on-chip comparator (Comp_A+), and Spy-Bi-Wire debug interface - deployed in battery-powered sensor nodes requiring sub-1 µs wake-up and <0.1 µA off-mode retention.
For engineers reviewing the MSP430G2153IPW28 datasheet, MSP430G2153IPW28 pinout, MSP430G2153IPW28 application, or MSP430G2153IPW28 equivalent, key selection criteria include its 1.8–3.6 V supply range, absence of ADC10 (distinguishing it from G2x53 variants), verified 28-pin TSSOP package mapping, and confirmed support for USCI_A0 (UART/LIN/IrDA/SPI) and USCI_B0 (SPI/I²C) peripherals.
Technical Context
The MSP430G2153IPW28 implements a 16-bit CPU with constant generators and seven addressing modes, executing register-to-register operations in one CPU clock cycle. Its basic clock module integrates DCO (digitally controlled oscillator), internal LF oscillator, and external crystal support (32 kHz), enabling MCLK/SMCLK/ACLK generation with sub-1 µs active-mode wake-up from LPM4.
It supports five low-power modes (LPM0–LPM4), with LPM4 drawing only 0.1 µA (RAM retention). The device includes two 16-bit Timer_A modules (TA0 and TA1), each with three capture/compare registers, and Comp_A+ with eight selectable input channels - but no ADC10, as explicitly noted in Table 1 and functional block diagrams for G2x13 family members.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | 16-bit RISC CPU with 16 registers and constant generators; enables high code efficiency and deterministic 62.5-ns instruction cycle at 16 MHz |
| Flash / RAM | 16 KB flash memory + 256 B RAM; supports in-system programming via Spy-Bi-Wire and UART-based BSL with password protection |
| Supply Voltage | 1.8 V to 3.6 V; allows direct operation from single-cell Li-ion, alkaline, or coin-cell batteries without regulation |
| Ultra-Low Power | Active mode: 230 µA @ 1 MHz / 2.2 V; Standby: 0.5 µA; Off mode (RAM retention): 0.1 µA - validated per SLAS735J Rev. May 2013 |
| Timers | Two 16-bit Timer_A modules (TA0, TA1), each with three capture/compare registers; supports PWM, input capture, and interval timing |
| Communication | USCI_A0 (UART/LIN/IrDA/SPI) and USCI_B0 (SPI/I²C); no hardware UART auto-baud detection - not present in G2x13 series per feature table |
| Comparator | Comp_A+ with eight input channels (CA0–CA7); supports analog signal compare, slope A/D conversion, and windowed monitoring |
Pinout & Package
Package: 28-pin TSSOP (PW28), 0.65 mm pitch, body size 9.7 × 4.4 mm - RoHS-compliant, surface-mountable, and compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, DVCC | Digital power supply | Primary 1.8–3.6 V digital rail; must be decoupled locally with 100 nF ceramic capacitor |
| 2, P1.0/TA0CLK/ACLK/A0/CA0 | Multi-function I/O | Configurable as timer clock input, ACLK output, ADC analog input (not used in G2x13), or comparator input CA0 |
| 5, P1.3/ADC10CLK/CAOUT/VREF-/VEREF-/A3/CA3 | Comparator output & reference | CAOUT = comparator output; VREF-/VEREF- = negative reference (shared with comparator); no ADC10 function enabled |
| 14, P2.5/TA1.2 | Timer1_A capture/compare | CCI2B input or Out2 output for TA1; supports PWM generation or edge-triggered capture on P2.5 |
| 24, RST/NMI/SBWTDIO | Reset & debug I/O | Active-low reset; NMI input; bidirectional Spy-Bi-Wire data line - requires external 47 kΩ pullup for reliable programming |
| 25, TEST/SBWTCK | Debug clock input | Test mode select during JTAG entry; SBWTCK input for Spy-Bi-Wire serial programming and emulation |
| 26–27, XOUT/P2.7, XIN/P2.6/TA0.1 | Crystal oscillator interface | Supports 32.768 kHz watch crystal; XIN also serves as TA0.1 compare output - requires load capacitors per crystal spec |
| 28, DVSS | Digital ground | Return path for DVCC; must be connected to system ground plane with low-inductance trace |
Key Features
| Feature | Design Value |
|---|---|
| Five software-selectable low-power modes | LPM0–LPM4 enable system-level energy optimization; LPM4 draws only 0.1 µA with RAM retention - critical for multi-year battery life |
| Spy-Bi-Wire debug interface | 2-wire JTAG-compatible protocol using RST/SBWTDIO and TEST/SBWTCK; eliminates need for full 4-pin JTAG header |
| Capacitive-touch capable I/O | P1.x and P2.x pins support pin-oscillator enable for low-cost touch sensing - no external RC network required |
| On-chip brownout detector | Monitors DVCC and asserts reset if voltage drops below threshold - prevents erratic code execution during battery sag |
| Programmable code protection | Security fuse disables flash read/write after programming; prevents reverse engineering and unauthorized firmware extraction |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430G2213IPW28 | Same 28-pin TSSOP package, identical peripherals, but only 2 KB flash and 256 B RAM | Lower memory capacity limits firmware complexity; suitable for fixed-function, non-upgradable devices | Select when application firmware fits within 2 KB and cost sensitivity outweighs field-upgrade capability |
| MSP430G2131IPW28 | 20-pin TSSOP variant; lacks Port P3 and all TA1 functionality; no USCI_B0 (I²C/SPI) | Reduced I/O count (16 vs. 24) and missing I²C restrict use to simpler UART-only or GPIO-centric designs | Choose only when board space is constrained and full 24-pin I/O and dual USCI are unnecessary |
Compared with MSP430G2213IPW28 and MSP430G2131IPW28, the MSP430G2153IPW28 delivers optimal balance of memory headroom (16 KB flash), full dual-USCI support, and 24 I/O pins - making it the preferred choice for upgradable, communication-rich embedded sensors where long-term design reuse matters.

FAQ
Does the MSP430G2153IPW28 include an ADC10 analog-to-digital converter?
No, the MSP430G2153IPW28 does not include ADC10. As confirmed in Table 1 and multiple notes in SLAS735J Rev. May 2013, ADC10 is exclusive to MSP430G2x53 devices (e.g., MSP430G2553IPW28). The MSP430G2153IPW28 relies on its on-chip Comp_A+ for analog threshold detection and slope A/D conversion instead.
What is the maximum operating frequency of the MSP430G2153IPW28 DCO?
The digitally controlled oscillator (DCO) in the MSP430G2153IPW28 supports calibrated frequencies up to 16 MHz, as stated in the "Basic Clock Module Configurations" section and verified in the calibration data tables (e.g., CAL_DCO_16MHZ at 0x0002). This enables full-speed execution in Active Mode without external crystals.
Can the MSP430G2153IPW28 be programmed using UART-based bootloader (BSL)?
Yes, the MSP430G2153IPW28 supports UART-based BSL programming using P1.1 (TXD) and P1.5 (RXD), as documented in Table 9 of SLAS735J. The BSL is protected by a user-defined password and resides in ROM - enabling field firmware updates without JTAG hardware.
Is the MSP430G2153IPW28 pin-compatible with the MSP430G2553IPW28?
No, the MSP430G2153IPW28 is not pin-compatible with the MSP430G2553IPW28. Although both use the 28-pin TSSOP package, their pin functions differ significantly - notably, P1.3 on MSP430G2153IPW28 provides CAOUT/VREF-/VEREF-/CA3 but no ADC10CLK, while the same pin on MSP430G2553IPW28 adds ADC10CLK functionality. PCB layout cannot be reused.
What debug interface does the MSP430G2153IPW28 support?
The MSP430G2153IPW28 supports Spy-Bi-Wire (SBW) debugging via pins RST/NMI/SBWTDIO (Pin 24) and TEST/SBWTCK (Pin 25). This 2-wire interface is fully compatible with TI's MSP-FET and IAR/Energia IDEs - eliminating the need for 4-pin JTAG headers and reducing debug footprint.
