The device has the SAME FUNCTIONALITY and PINOUT as the compared device but is NOT an exact equivalent.
MSP430F423A is recommended for new designs
TI does not recommend using this part in a new design. This product continues to be in production to support existing customers.
The TI MSP430 family of ultra-low-power microcontrollers consists of several devices featuring different sets of peripherals targeted for various applications. The architecture, combined with five low-power modes, is optimized to achieve extended battery life in portable measurement applications. The device features a powerful 16-bit RISC CPU, 16-bit registers, and constant generators that contribute to maximum code efficiency. The digitally controlled oscillator (DCO) allows the device to wake up from low-power modes to active mode in less than 6 µs.
The MSP430F42x series are microcontroller configurations with three independent 16-bit sigma-delta ADCs, each with an integrated differential programmable gain amplifier input stage. Also included is a built-in 16-bit timer, 128-segment LCD drive capability, hardware multiplier, and 14 I/O pins.
Typical applications include high-resolution applications such as handheld metering equipment, weigh scales, and energy meters.
