Product details
Overview
MSP430F2132QRHBREP from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller with 8 KB flash, 512 B RAM, 10-bit 200-ksps ADC, dual 16-bit timers (Timer0_A3 with 3 capture/compare registers, Timer1_A2 with 2), USCI modules supporting UART/LIN/IrDA/SPI/I²C, and comparator for slope A/D or battery monitoring - deployed in battery-powered sensor nodes and industrial telemetry endpoints.
For engineers reviewing the MSP430F2132QRHBREP datasheet, MSP430F2132QRHBREP pinout, MSP430F2132QRHBREP application, or MSP430F2132QRHBREP equivalent, key selection criteria include extended temperature support (–40°C to 125°C), Spy-Bi-Wire debug interface, integrated DCO with <1 µs wake-up, brownout detection, and QFN-32 (RHB) package compatibility with space-constrained PCB layouts.
Technical Context
The MSP430F2132QRHBREP implements a 16-bit RISC CPU with constant generators and seven addressing modes, enabling single-cycle register operations and high code efficiency. Its basic clock module integrates a digitally controlled oscillator (DCO), internal VLO, 32-kHz crystal input, and HF crystal support up to 16 MHz - all configurable via software-selectable low-power modes (LPM0–LPM4).
Peripherals are memory-mapped and accessible via full instruction set; the ADC10 includes autoscan, internal reference, sample-and-hold, and data transfer controller (DTC) for CPU-offload conversion sequencing. The USCI_A0 and USCI_B0 modules provide independent asynchronous/synchronous serial interfaces with dedicated interrupt vectors and register-level control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | 16-bit RISC CPU with 16 general-purpose registers and constant generators - enables compact firmware and deterministic 62.5-ns instruction cycle time at 16 MHz. |
| Memory | 8 KB + 256 B flash (main + info segments) and 512 B RAM - supports in-system programming, BSL password-protected UART loading, and calibration data retention in segment A. |
| ADC | 10-bit SAR ADC with 200-ksps sampling, internal reference, autoscan, and DTC - allows autonomous multi-channel acquisition without CPU intervention. |
| Timers | Timer0_A3 (3 capture/compare registers) and Timer1_A2 (2 capture/compare registers) - deliver PWM generation, input capture, interval timing, and synchronized interrupt handling. |
| Communication | USCI_A0 (UART/LIN/IrDA/SPI) and USCI_B0 (SPI/I²C) - provide dual independent serial interfaces with hardware flow control, baud rate generation, and protocol-specific status flags. |
| Power Management | Active mode: 250 µA @ 1 MHz / 2.2 V; Standby: 0.7 µA; Off mode (RAM retention): 0.1 µA - optimized for multi-year battery life in intermittent-sensing applications. |

Pinout & Package
Package: 32-pin QFN (RHB), 5 mm × 5 mm, 0.5 mm pitch, exposed thermal pad (recommended connection to DVSS).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P1.0/TACLK/ADC10CLK/CAOUT | Timer/ADC/Comparator output | Provides timer clock input, ADC conversion trigger, and comparator output - enables synchronized analog-digital event timing. |
| P2.2/TA0.0/A2/CA4/CAOUT | Multi-function I/O | Serves as Timer0_A3 compare output, ADC channel A2 input, and comparator output - supports mixed-signal signal routing on single pin. |
| P3.4/UCA0TXD/UCA0SIMO | USCI_A0 transmit/data | Transmits UART data or SPI slave-in/master-out data - selectable per USCI mode register, with dedicated TX interrupt flag (UCA0TXIFG). |
| RST/NMI/SBWTDIO | Reset/debug I/O | Combines power-on reset, nonmaskable interrupt, and Spy-Bi-Wire test data I/O - enables single-wire debugging without JTAG header footprint. |
| TEST/SBWTCK | Debug clock input | Selects Spy-Bi-Wire test mode and connects to device protection fuse - required for secure programming and boundary-scan verification. |
Key Features
| Feature | Design Value |
|---|---|
| Dual USCI modules | USCI_A0 (UART/LIN/IrDA/SPI) and USCI_B0 (SPI/I²C) operate independently with separate clocks, buffers, and interrupt vectors - eliminates resource contention in multi-protocol systems. |
| ADC10 with DTC | Data Transfer Controller automates storage of up to 16 conversion results into RAM - removes CPU polling overhead and enables precise timing-critical sampling sequences. |
| Ultra-fast wake-up | DCO stabilizes in <1 µs from LPM3/LPM4 - ensures responsive real-time reaction to external interrupts while maintaining µA-level sleep current. |
| Calibrated DCO | Four factory-trimmed frequencies (1/8/12/16 MHz) accurate to ±1% at 2.2 V and 25°C - eliminates need for external crystal in cost-sensitive timing applications. |
| Comparator_A+ | Supports precision slope A/D conversion, battery voltage supervision, and external analog monitoring with programmable hysteresis - replaces discrete comparator + ADC combinations. |

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 |
|---|---|---|---|
| MSP430F2013IRSAT | 4 KB flash, 128 B RAM, same RHB package but only one 16-bit timer (Timer_A) and no USCI_B0 - lacks I²C and second SPI interface. | Targeted at simpler sensor hubs with single-protocol communication and lower memory requirements. | Select when cost sensitivity outweighs dual-USCI flexibility and extended flash/RAM needs. |
| MSP430FR2132IPW | Ferroelectric RAM (FRAM) instead of flash: 8 KB FRAM, 1 KB RAM, same peripherals but faster write endurance and lower active power (115 µA/MHz). | Better suited for frequent data logging or over-the-air firmware updates where flash wear-out is a concern. | Prefer for high-write-cycle applications; note FRAM requires different initialization sequence and lacks segment-level erase granularity. |
Compared with MSP430F2132QRHBREP, MSP430F2013IRSAT reduces memory and peripheral count for cost-driven designs, while MSP430FR2132IPW trades flash endurance for FRAM's instant-write capability and lower active current - both require layout review due to differing package footprints (RSAT = 16-pin QFN, IPW = 20-pin TSSOP).

FAQ
What is the operating temperature range of the MSP430F2132QRHBREP?
The MSP430F2132QRHBREP is rated for –40°C to +125°C, meeting Enhanced Product (EP) specifications for extended thermal performance in industrial and aerospace deployments. This range is validated across all electrical parameters in the SLAS913A datasheet, including flash programming, ADC accuracy, and timer stability - no derating required within this span.
Does the MSP430F2132QRHBREP support in-system programming without external voltage?
Yes, the MSP430F2132QRHBREP supports in-system programming via JTAG or Spy-Bi-Wire using only the standard 1.8–3.6 V supply - no external programming voltage is needed. Its bootstrap loader (BSL) also enables UART-based flash updates with user-defined password protection, as documented in SLAU319.
How many I/O pins does the MSP430F2132QRHBREP provide, and what are their capabilities?
The MSP430F2132QRHBREP provides 24 usable I/O pins across Ports P1, P2, and P3 - each individually configurable as input/output with programmable pullup/pulldown resistors and edge-selectable interrupts. All pins support peripheral multiplexing, including timer capture/compare, ADC inputs, USCI signals, and comparator functions.
What clock sources are available on the MSP430F2132QRHBREP?
The MSP430F2132QRHBREP integrates four clock sources: a digitally controlled oscillator (DCO) with four factory-calibrated frequencies (±1%), an internal very-low-power oscillator (VLO), a 32-kHz watch crystal input, and support for HF crystals up to 16 MHz. These feed the ACLK, MCLK, and SMCLK domains with software-selectable routing.
Is the MSP430F2132QRHBREP pin-compatible with other MSP430F2xx devices in the RHB package?
No - the MSP430F2132QRHBREP has a unique pin mapping within the RHB package. While other F2xx devices like MSP430F2013 use RHB, their pin functions differ significantly (e.g., missing USCI_B0 signals, reduced timer resources). Direct replacement requires schematic and firmware validation; refer to SLAS913A Table "Terminal Functions" for authoritative assignment.
