MSP430G2232IPW14R Technical Specifications

MSP430G2232IPW14R Key Features

• 16-bit RISC core for efficient control tasks and deterministic timing with lower code size.
• Low-voltage operation down to 1.8 V, enabling longer battery life and compatibility with 2-cell and 3-cell battery systems.
• Compact memory footprint??2 KB flash plus 128 bytes RAM??reduces component count for simple embedded functions.
• Integrated Timer_A and USI to handle pulse timing, PWM and basic serial protocols without extra ICs.
• 14-pin TSSOP package offers denser board layouts and smaller form factor than typical DIP alternatives.

Typical Applications

• Battery-powered sensor nodes and handheld controls where ultra-low active and standby current extends battery life for longer deployments in the field.
• Simple industrial controls that require one precise timer, a serial interface and non-volatile program memory in a small package for compact panels.
• Consumer peripherals such as remote controls, thermostats or LED drivers where limited memory and low quiescent currents lower BOM and energy use.
• Protocol bridges or simple data concentrators that use the USI for SPI or I2C-like signaling and the timer for accurate sampling and event capture.

MSP430G2232IPW14R Advantages vs Typical Alternatives

The device favors lower power and smaller size versus many 8-bit and larger 16-bit alternatives. It delivers a 16-bit core at up to 16 MHz while consuming far less active and standby current. The integrated Timer_A and USI replace at least one external timer or serial bridge. In practice this yields fewer components, lower board area and lower BOM cost. The TSSOP-14 package and tape-and-reel option simplify automated assembly and scaling for higher volumes.

FAQ

What package does it use?

The part is supplied in a 14-pin TSSOP package (IPW14). The device also carries an R suffix when supplied on tape-and-reel for automated pick-and-place assembly.

What voltage range is supported?

The device runs from 1.8 V to 3.6 V. This range supports common battery configurations and standard 3.3 V systems while allowing lower-voltage operation to conserve power.

How much flash and RAM are available?

The MCU provides compact non-volatile program storage and a small SRAM region suitable for control code and limited runtime buffers, enabling simpler firmware and minimal external memory needs.

Which serial interfaces are onboard?

The universal serial interface (USI) supports common serial protocols such as SPI-like and I2C-like communication. This reduces the need for external bridge ICs for simple host or sensor links.

Is it suitable for battery-powered designs?

Yes. The device targets ultra-low-power operation with active and standby modes optimized for long battery life. It is commonly used where minimizing quiescent current is a priority.
