MSP430F2132IPWR Technical Specifications

MSP430F2132IPWR Key Features

• Single 16-bit RISC CPU core for compact code and wider data paths versus typical 8-bit MCUs.
• 10-bit ADC with up to 8 channels for accurate, multi-channel analog measurement in sensor systems.
• Low-voltage operation from 1.8 V to 3.6 V, enabling longer battery life and compatibility with common coin-cell and Li?ion chemistries.
• Integrated USI that supports SPI and I2C, reducing external translator ICs and saving board area.
• Compact 20-pin TSSOP package that eases integration into space-constrained PCBs and simplifies routing compared to larger packages.
• Multiple low-power modes for sleep and standby that improve efficiency and reduce system average current draw compared with always?on designs.

Typical Applications

• Battery-powered sensor nodes where low voltage and low current draw extend operational lifetime for months or years on limited power sources.
• Handheld measurement instruments that need a 10-bit ADC and a compact MCU to handle data acquisition and user I/O in small enclosures.
• Industrial sensor interfaces requiring robust temperature range (-40 ??C to 85 ??C) and reliable serial links such as SPI or I2C to upstream controllers.
• Portable consumer devices that demand small board area, few external components, and flexible I/O for buttons, LEDs, and basic displays.

MSP430F2132IPWR Advantages vs Typical Alternatives

The MSP430F2132IPWR offers a stronger balance of energy efficiency and integration when compared to many 8-bit MCUs. Its 16-bit core processes wider data words for faster arithmetic and lower code size in some tasks.

FAQ

What is the operating voltage?

The device operates from 1.8 volts to 3.6 volts. This range supports common battery chemistries and allows designers to run at lower voltages for improved energy efficiency while remaining compatible with 3.3 V systems.

How many ADC channels are available?

The microcontroller provides a 10-bit ADC with up to eight multiplexed input channels. This lets a single device sample multiple sensors or inputs without external ADCs, simplifying BOM and routing.

What serial interfaces does it include?

It includes a Universal Serial Interface (USI) that can be configured for SPI or I2C communications. This provides flexible connectivity to sensors, displays, EEPROMs, and other peripherals without extra UART hardware.

Which package should I expect?

This part is supplied in a 20-pin TSSOP (PW) package. The smaller footprint helps reduce board area and is suitable for compact industrial or portable designs where space is limited.

Is it suitable for low-temperature environments?

Yes. The device is specified for an industrial temperature range down to -40 ??C and up to 85 ??C, making it suitable for outdoor, industrial, and automotive-adjacent sensing applications within that range.
