MSP430G2452IPW20R 16-Bit Low-Power Microcontroller, 20-Pin TSSOP

MSP430G2452IPW20R Overview

The MSP430G2452IPW20R is a low?power 16?bit microcontroller from Texas Instruments (TI). It combines a 16?bit RISC CPU with on?chip Flash and RAM, a 10?bit ADC, a 16?bit timer, and a serial interface in a 20?pin TSSOP package. The device targets battery?powered and embedded control tasks that demand low energy use and compact firmware storage. Designers get a small BOM, multiple low?power modes, and standard peripheral building blocks. For procurement and further IC resources see IC Manufacturer.

MSP430G2452IPW20R Technical Specifications

MSP430G2452IPW20R Key Features

• 16?bit RISC core with deterministic instruction timing for efficient control and compact code size.
• 16 KB Flash plus 512 B RAM for firmware and parameter storage, enabling moderate feature sets without external memory.
• Integrated 10?bit ADC (ADC10) and up to 8 channels for onboard analog sensing and data acquisition.
• 16?bit Timer_A and capture/compare registers for precise timing, PWM, and event capture in control applications.
• USI serial interface supports common bus protocols, enabling straightforward connectivity to sensors and peripherals.
• Low operating voltage range and multiple low?power modes for longer battery life in portable designs.

Typical Applications

• Battery?powered sensors and data loggers where low standby current and multiple sleep modes extend battery life for months to years.
• Portable medical instruments that require compact Flash for measurement firmware and a 10?bit ADC for analog signal capture.
• Industrial sensors and node controllers that need reliable timing, simple serial interfaces, and operation across ?40 ??C to +85 ??C.
• Consumer handheld products that demand small PCB footprint, a 20?pin TSSOP package, and integrated peripherals to minimize external components.

MSP430G2452IPW20R Advantages vs Typical Alternatives

The device offers a balance of flash capacity, peripheral integration, and ultra?low power that often beats 8?bit controllers for control tasks in the same price band. Compared with higher?end MCUs, it uses far less active and standby power while still providing a 16?bit CPU and a 10?bit ADC. Its 20?pin TSSOP package is smaller than many DIP or larger QFN alternatives, which reduces PCB area and BOM cost for space?constrained designs.
