Product details
Overview
MSP430F435IPNR from Texas Instruments is an ultralow-power 16-bit mixed-signal microcontroller featuring 16 KB + 256 B flash memory, 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 such as handheld meters and sensor nodes.
For engineers reviewing the MSP430F435IPNR datasheet, MSP430F435IPNR pinout, MSP430F435IPNR application, or MSP430F435IPNR equivalent, key selection considerations include its 80-pin QFP package, 1.8–3.6 V supply range, <6 µs wake-up from standby, 280 µA active current at 1 MHz/2.2 V, and integrated LCD/ADC/timer peripherals for compact embedded sensing and display control.
Technical Context
The MSP430F435IPNR implements a 16-bit RISC CPU with constant generators and a digitally controlled oscillator (DCO) enabling sub-6 µs wake-up from low-power modes. Its architecture supports five power-saving modes optimized for extended battery life in intermittent-sampling applications.
It integrates analog and digital peripherals on a single die: a 12-bit ADC with sample-and-hold and autoscan, dual 16-bit timers with capture/compare and shadow registers, two USARTs configurable as UART or SPI, and an LCD controller supporting static to 4-mux displays with up to 160 segments.
