Product details
Overview
MSP430F435IPZR from Texas Instruments is an ultralow-power 16-bit mixed-signal microcontroller featuring 16 KB + 256 B Flash, 512 B RAM, integrated 12-bit ADC with internal reference and autoscan, dual 16-bit timers (Timer_A3 and Timer_B3), two USARTs, LCD driver for up to 160 segments, and hardware multiplier-designed for battery-powered portable measurement systems with on-chip LCD display.
For engineers reviewing the MSP430F435IPZR datasheet, MSP430F435IPZR pinout, MSP430F435IPZR application, or MSP430F435IPZR equivalent, key selection criteria include its 100-pin QFP package, −40°C to 85°C industrial temperature range, 1.8–3.6 V supply, <6 µs wake-up from standby, and full ADC12 implementation-critical for sensor signal acquisition and real-time display in handheld meters and energy monitoring devices.
Technical Context
The MSP430F435IPZR implements a 16-bit RISC CPU with constant generators and a digitally controlled oscillator (DCO) enabling sub-6 µs active-mode wake-up. Its architecture supports five power-saving modes, including off mode with 0.1 µA RAM retention, optimized for extended battery life in intermittent-sensing applications.
It integrates a 12-bit successive-approximation ADC12 with 8 input channels, internal 2.5 V reference, sample-and-hold, and autoscan-capable of <10 µs conversion time-and a dedicated LCD controller supporting static to 4-mux configurations with programmable bias and frame frequency.
