MSP430G2452IPW20 Overview

The MSP430G2452IPW20 is an ultra-low-power 16-bit microcontroller in a 20-pin through-hole package. It combines a compact memory footprint with analog and timer peripherals for sensor, meter, and portable control tasks. The device runs at up to 16 MHz, includes a 10-bit ADC and a 16-bit timer, and operates from a 1.8 V to 3.6 V supply. For detailed sourcing and complementary devices see IC Manufacturer.

MSP430G2452IPW20 Technical Specifications

MSP430G2452IPW20 Key Features

• One core 16-bit RISC CPU with compact instruction set for deterministic control and lower code size.
• 10-bit ADC available with multiple channels, enabling direct sensor interfacing without external converters.
• Low-voltage operation from 1.8 V to 3.6 V for better battery life and compatibility with common battery chemistries.
• Integrated Timer_A and watchdog functions that improve system reliability and reduce external component count.

Typical Applications

• Battery-powered sensor nodes where ultra-low standby current and a 16-bit core deliver longer run times and simpler code.
• Handheld instruments that require a small flash footprint, on-chip ADC, and low-voltage operation for compact power management.
• Home appliance control panels that need deterministic timers, simple serial interfaces, and a robust through-hole package for easy assembly.
• Industrial small-control and monitoring tasks where a 16-bit MCU with proven low-power modes reduces system complexity and BOM cost.

MSP430G2452IPW20 Advantages vs Typical Alternatives

The device offers a tighter integration of analog, timing, and serial peripherals in a single small 20-pin package. Compared with larger MCUs, it uses less flash and RAM while still supporting a 16-bit CPU and a 10-bit ADC, making it more efficient for simple control tasks. The broad supply range of 1.8?C3.6 V and ultra-low-power modes favor battery and portable designs more than many 8-bit or higher-power 32-bit alternatives.

FAQ

What is the supply voltage range?

The device operates from 1.8 V to 3.6 V. This range supports common single-cell battery designs and standard 3.3 V systems without additional level shifting.

How much flash and RAM are on-chip?

On-chip nonvolatile storage is 16 KB of flash memory paired with 512 bytes of RAM. That balance suits compact firmware and modest runtime data buffering.

Which analog capabilities does it include?

It integrates a 10-bit successive-approximation ADC (ADC10) with multiple input channels. This enables direct connection of sensors and analog signals without an external ADC in many designs.

What package is IPW20?

The IPW20 suffix designates a 20-pin through-hole PDIP package. This format eases prototyping, manual assembly, and retrofit into legacy boards that use DIP sockets.

Is it suitable for low-power battery operation?

Yes. The architecture and low-voltage operation reduce active and standby current. The device supports MSP430 low-power modes, which help extend battery life in fielded products.
