MSP430F2131IPW 16-bit Low-Power Microcontroller (IPW package)

MSP430F2131IPW Overview

The MSP430F2131IPW is a low-power, 16-bit microcontroller designed for compact industrial and consumer control tasks. It combines a 16-bit CPU with on-chip flash and static RAM to deliver more code density and lower power than many 8-bit alternatives. The device comes in a 20-pin TSSOP package and supports a wide supply range for flexible system designs. See the product family at IC Manufacturer for ordering and compliance details.

MSP430F2131IPW Technical Specifications

MSP430F2131IPW Key Features

• Single 16-bit core for higher computational efficiency than 8-bit MCUs, enabling more compact code and faster arithmetic.
• Integrated flash memory for non-volatile code storage and in-system reprogramming, which simplifies firmware updates and reduces BOM cost.
• Low-voltage operation from 1.8 V to 3.6 V, allowing direct interface with a range of battery chemistries and 3.3 V systems for easier system integration.
• On-chip 10-bit ADC and timer resources that support precise analog sensing and deterministic timing for control loops and motor or power-management tasks.
• Compact 20-pin TSSOP package that is smaller than many DIP or SOIC alternatives, saving board space in tight industrial or wearable designs.

Typical Applications

• Battery-powered sensor nodes and portable instrumentation where low idle current and sub-3.6 V operation extend runtime and reduce power management complexity.
• Precision analog front-ends for small industrial controllers that need a 10-bit ADC and timer capture/compare for reliable measurement and control.
• Consumer appliances and handheld devices that require compact 20-pin packaging and up to 16 MHz processing for responsive user interfaces.
• Embedded control for small motors, pumps, or actuators where deterministic Timer_A channels and dedicated I/O simplify PWM generation and feedback capture.

MSP430F2131IPW Advantages vs Typical Alternatives

The device offers lower power consumption and higher code density compared with many 8-bit MCUs, while keeping a smaller footprint than many 32-bit controllers in similar roles. With a 16-bit core, integrated flash, and a 10-bit ADC, it provides a balanced mix of performance and analog capability for cost-sensitive designs. The 20-pin TSSOP package further reduces board area versus larger packages, which benefits compact and cost-driven systems.

FAQ

What core does it use?

It uses a 16-bit RISC core. This provides more arithmetic range and denser code than 8-bit cores, helping to reduce ROM use and improve response time in control tasks.

What is the supply voltage range?

The specified supply range is 1.8 V to 3.6 V, which allows direct operation from common battery sources and standard 3.3 V system rails without extra power conversion.

How much non-volatile memory is available?

The device includes 2 KB of on-chip flash memory, enabling compact firmware storage and in-field reprogramming for iterative product development and updates.

Does it include an ADC?

Yes, a built-in 10-bit ADC supports moderate-resolution analog measurements suitable for sensors, voltage monitoring, and small control loops without external converters.

Which package is offered?

It is supplied in a 20-pin TSSOP package (suffix PW), which is smaller than many through-hole or SOIC offerings and is compatible with standard surface-mount assembly processes.
