Texas Instruments MSP430F436IPZR

Overview

MSP430F436IPZR 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 systems.

For engineers reviewing the MSP430F436IPZR datasheet, MSP430F436IPZR pinout, MSP430F436IPZR application, or MSP430F436IPZR 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), LCD segment count support, and ADC12 integration status.

Technical Context

The MSP430F436IPZR 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 sensor-based data acquisition.

It integrates a 12-bit ADC12 module with sample-and-hold, autoscan, and internal reference-confirmed for MSP430F43x (not F43x1) variants-and features dual 16-bit timers with capture/compare registers, one USART (USART0) configurable as UART or SPI, and an on-chip comparator.

FAQ

What is the maximum operating frequency of the MSP430F436IPZR?

The MSP430F436IPZR operates at up to 8 MHz using its integrated FLL+ oscillator. Its 16-bit RISC core achieves a 125-ns instruction cycle time, enabling deterministic real-time execution for time-critical sensor sampling and display refresh routines within the MSP430F436IPZR architecture.

Does the MSP430F436IPZR include an integrated ADC module?

Yes, the MSP430F436IPZR includes the ADC12 module-a 12-bit successive-approximation analog-to-digital converter with internal reference, sample-and-hold, and autoscan capability. This ADC is confirmed for the MSP430F43x series (including MSP430F436IPZR), distinguishing it from the F43x1 variant where ADC12 is omitted.

What LCD configurations does the MSP430F436IPZR support?

The MSP430F436IPZR supports LCD displays with up to 160 segments using 1/2 or 1/4 bias and 1-, 2-, 3-, or 4-MUX configurations. It provides dedicated segment outputs (S0–S39) and backplane outputs (COM0–COM3), enabling direct drive of alphanumeric or graphical segmented displays without external drivers in the MSP430F436IPZR.

How many USART interfaces does the MSP430F436IPZR have?

The MSP430F436IPZR includes one USART (USART0), configurable in software as either asynchronous UART or synchronous SPI. Unlike the MSP430F44x series, it does not implement USART1-this distinction is explicitly documented in the SLAS344G datasheet for the MSP430F436IPZR family.

What is the pin count and package type of the MSP430F436IPZR?

The MSP430F436IPZR uses a 100-pin plastic quad flat pack (PZ package), as indicated by the "IPZR" suffix. This package provides 48 general-purpose I/O pins, dedicated LCD segment/backplane terminals, analog inputs (A3–A7), and full JTAG debug interface (TCK/TMS/TDI/TDO) for development and production programming of the MSP430F436IPZR.
