Product details
Overview
MSP430F1132IPWR from Texas Instruments is an ultralow-power 16-bit RISC microcontroller with 8KB flash, 256B RAM, 10-bit 200-ksps ADC, Timer_A3 with three capture/compare registers, and basic clock module supporting internal DCO, 32-kHz crystal, or external resistor tuning. It operates from 1.8 V to 3.6 V and achieves 0.1 µA off-mode current with RAM retention-ideal for battery-powered sensor nodes and portable measurement systems.
For engineers reviewing the MSP430F1132IPWR datasheet, MSP430F1132IPWR pinout, MSP430F1132IPWR application, or MSP430F1132IPWR equivalent, key selection criteria include its 20-pin TSSOP package, absence of integrated USART (unlike MSP430x12x2), five low-power modes, sub-6-µs wake-up time, and JTAG/debug support via P1.x pins.
Technical Context
The MSP430F1132IPWR implements a 16-bit RISC CPU with 125 ns instruction cycle time, constant generators for code efficiency, and a digitally controlled oscillator (DCO) enabling wake-up from standby in under 6 µs. Its memory map includes 8KB flash (0xFFFF–0xE000), 256B RAM (0x02FF–0x0200), and 256B information memory.
It integrates a 10-bit SAR ADC with internal reference, sample-and-hold, autoscan, and data transfer controller (DTC); Timer_A3 with three independent capture/compare registers; and dual I/O ports (P1: 8-bit, P2: 6-bit) with edge-selectable interrupts. No USART peripheral is present-this distinguishes it from the MSP430x12x2 family.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | 16-bit RISC CPU with 125 ns instruction cycle; register-based execution enables high code density and deterministic timing. |
| Flash / RAM | 8KB flash + 256B RAM; supports in-system programming and BSL via UART using P1.1/P2.2 pins. |
| ADC Performance | 10-bit SAR ADC at 200 ksps with internal reference, autoscan, and DTC-enables unattended multi-channel sampling without CPU intervention. |
| Power Modes | Five software-selectable low-power modes; LPM4 draws only 0.1 µA with RAM retention-extends coin-cell life to years in intermittent-sensing applications. |
| Clock System | Basic clock module with DCO, 32-kHz crystal support, and external resistor tuning; ACLK, SMCLK, and MCLK sourced independently for flexible peripheral timing. |
| Supply Range | 1.8 V to 3.6 V operation; brownout protection ensures reliable reset during voltage sag-critical for energy-harvesting and battery-depleted conditions. |
| I/O Count | 14 GPIO (P1.0–P1.7, P2.0–P2.5); all support interrupt-on-change with individually configurable edges-simplifies wake-up logic for external events. |
Pinout & Package
Package: 20-pin TSSOP (PW), body size 6.5 mm × 4.4 mm, 0.65 mm pitch, exposed thermal pad (recommended connection to VSS).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P1.0/TACLK/ADC10CLK | GPIO / Timer_A clock input / ADC conversion clock | Configurable as digital I/O, Timer_A clock source, or ADC sampling trigger-enables synchronous sampling control. |
| P1.1/TA0/BSL_TX | GPIO / Timer_A CCI0A / BSL transmit | Primary UART TX pin for bootloader communication; also serves as Timer_A capture input or compare output. |
| P1.2/TA1 | GPIO / Timer_A CCI1A | Dedicated capture/compare channel for PWM generation or event timing-supports motor control or pulse-width measurement. |
| P1.3/TA2 | GPIO / Timer_A CCI2A | Third Timer_A capture/compare channel; enables simultaneous three-phase timing or multi-signal correlation. |
| P1.4/SMCLK/TCK | GPIO / SMCLK output / JTAG test clock | Provides subsystem clock to peripherals; doubles as TCK for boundary-scan and debug programming. |
| P2.0/ACLK/A0 | GPIO / ACLK output / ADC analog input A0 | Drives auxiliary clock to external circuitry; also functions as first ADC channel-reduces component count in clocked sensor interfaces. |
| P2.3/TA1/A3/VREF− | GPIO / Timer_A CCI1B / ADC A3 / ADC negative reference | Shared analog/digital resource: enables differential ADC measurements when paired with P2.4's VREF+. |
| RST/NMI | Reset / non-maskable interrupt input | Active-low hardware reset; double-function as NMI source for critical fault handling (e.g., power failure detection). |
| TEST | JTAG mode select input | Enables JTAG debug interface on P1.x pins-required for full-speed emulation and flash programming. |
| VCC / VSS | Power supply / ground | Single-supply operation; VSS must connect to QFN thermal pad to meet thermal and current leakage specs. |
Key Features
| Feature | Design Value |
|---|---|
| Ultralow-power operation | 0.1 µA off-mode current with RAM retention enables decade-scale battery life in wireless sensor endpoints. |
| Integrated 10-bit ADC with DTC | Autoscan across up to 8 channels and automatic result storage to RAM eliminates CPU polling overhead-reducing active time by >90%. |
| Three-channel Timer_A3 | Independent capture/compare registers support simultaneous PWM generation, input capture, and interval timing-ideal for motor control or signal analysis. |
| Programmable code protection | Security fuse prevents unauthorized read-out of flash contents-protects firmware IP in deployed consumer or industrial devices. |
| On-chip DCO with fast wake-up | DCO stabilizes in <6 µs from LPM3/LPM4, enabling rapid response to sensor interrupts while maintaining µA-level sleep currents. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultralow-power microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F1122IPWR | 4KB flash, same 20-pin TSSOP package, identical peripherals except reduced program memory. | Suitable for simpler firmware with smaller code footprint; lacks headroom for future feature expansion. | Select when application firmware fits within 4KB and cost sensitivity outweighs memory scalability needs. |
| MSP430F1132IRHB | Same 8KB/256B configuration but in 32-pin QFN (RHB) package with 22 GPIO and thermal pad. | Better thermal performance and higher I/O count; requires PCB redesign due to different footprint and pinout. | Choose for designs needing more analog inputs, enhanced thermal dissipation, or layout space for decoupling near VCC/VSS. |
Compared with MSP430F1122IPWR, the MSP430F1132IPWR provides double flash capacity for complex algorithms without changing package or power profile; versus MSP430F1132IRHB, it trades I/O and thermal capability for compact TSSOP integration in space-constrained modules.

FAQ
What is the maximum operating frequency of the MSP430F1132IPWR?
The MSP430F1132IPWR supports a maximum CPU clock frequency of 1 MHz at 2.2 V, with instruction cycle time of 125 ns. Its digitally controlled oscillator (DCO) is factory-trimmed for stability across voltage and temperature, and can be tuned via DCOCTL register-though sustained operation above 1 MHz is not specified or guaranteed per SLAS361D.
Does the MSP430F1132IPWR include a hardware USART peripheral?
No, the MSP430F1132IPWR does not include a hardware USART. Unlike the MSP430x12x2 family, the x11x2 series omits USART0 entirely. Serial communication must be implemented in software (bit-banged UART) or via external ICs. The device retains full JTAG and BSL support using P1.1 (TX) and P2.2 (RX) pins.
How many analog input channels does the ADC10 support on the MSP430F1132IPWR?
The ADC10 on the MSP430F1132IPWR supports up to eight analog input channels (A0–A7), though only six are physically accessible on the 20-pin TSSOP package: A0 (P2.0), A1 (P2.1), A2 (P2.2), A3 (P2.3), A4 (P2.4), and A5 (P3.0 is not available-so A5–A7 are unused in this variant). Channel selection is controlled via ADC10CTL1 and ADC10AE registers.
What debug interfaces are supported by the MSP430F1132IPWR?
The MSP430F1132IPWR supports JTAG debugging via the TEST pin and P1.x signals (TCK, TMS, TDI, TDO), enabled by asserting TEST high. It also supports Spy-Bi-Wire (2-wire JTAG) for reduced pin count. No SWD or ARM-style debug is available. Full debug capability-including flash programming, breakpoints, and real-time register inspection-is provided through TI's MSP-FET and compatible tools.
Is the MSP430F1132IPWR RoHS compliant and halogen-free?
Yes, the MSP430F1132IPWR is RoHS compliant and halogen-free per Texas Instruments' product change notification PCN SC120117001. It meets JEDEC J-STD-609 Category 1 for bromine/chlorine content and is rated for lead-free soldering profiles up to 260°C peak temperature, making it suitable for modern environmentally regulated manufacturing.
