Overview
MSP430F436IPN from Texas Instruments is an ultralow-power 16-bit mixed-signal microcontroller featuring 24KB+256B flash memory, 1KB RAM, integrated 12-bit ADC with internal reference, 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 and display systems.
For engineers reviewing the MSP430F436IPN datasheet, MSP430F436IPN pinout, MSP430F436IPN application, or MSP430F436IPN equivalent, key selection criteria include supply voltage range (1.8–3.6 V), active-mode current (280 µA at 1 MHz), wake-up time (<6 µs), ADC resolution and channel count, LCD segment drive capability, and QFP-80 package compatibility with industrial sensor and metering layouts.
Technical Context
The MSP430F436IPN implements a 16-bit RISC CPU with constant generators and a digitally controlled oscillator (DCO), enabling sub-6-µs wake-up from standby mode. Its architecture supports five power-saving modes optimized for extended battery life in portable instrumentation.
It integrates a 12-bit ADC12 module with sample-and-hold, autoscan, and internal reference; dual 16-bit timers with capture/compare and shadow registers; and a programmable LCD controller supporting 1–4 multiplex configurations - all operating within a single 1.8–3.6 V supply domain.

What is the maximum operating frequency of the MSP430F436IPN?
The MSP430F436IPN supports a maximum system clock (MCLK) of 8 MHz via its integrated FLL+ oscillator, derived from either the internal DCO or external XT2 crystal. This enables deterministic 125-ns instruction execution cycles while maintaining ultralow-power operation across all five power modes.
Does the MSP430F436IPN include an integrated ADC, and what are its key specifications?
Yes, the MSP430F436IPN includes a 12-bit ADC12 module with sample-and-hold, autoscan, and internal reference. It supports up to 8 input channels, achieves <10 µs conversion time, and features configurable resolution, sampling rate, and reference sources - all confirmed in the SLAS344G datasheet for the MSP430F436IPN device.
What LCD configuration does the MSP430F436IPN support?
The MSP430F436IPN integrates an LCD controller supporting up to 160 segments with 1/2–1/4 bias and 1–4 multiplex configurations. It drives common outputs (COM0–COM3) and segment outputs (S0–S39 plus dedicated pins), enabling direct connection to alphanumeric or custom segment displays without external bias generation.
Is the MSP430F436IPN pin-compatible with other devices in the MSP430x43x family?
Yes, the MSP430F436IPN shares identical pinout and package (80-pin QFP, PN) with MSP430F435IPN and MSP430F437IPN. All three devices are functionally compatible at the pin level, differing only in flash/RAM size and minor peripheral enablement - allowing drop-in replacement within the same PCB layout.
What development tools are recommended for the MSP430F436IPN?
Texas Instruments recommends the MSP-FET430UIF (USB-based debugger), MSP-TS430PZ100 target board (for PZ-package evaluation), and MSP-GANG430 production programmer.
