Texas Instruments MSP430F5436AIPZR

Overview

MSP430F5436AIPZR from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller with 192 KB flash, 16 KB RAM, 12-bit ADC (14 external + 2 internal channels), four USCI modules (dual UART/IrDA/SPI + dual I²C/SPI), three 16-bit timers (TA0/TA1/TB0), RTC, hardware multiplier, and DMA - deployed in battery-powered sensor nodes and portable meters.

For engineers reviewing the MSP430F5436AIPZR datasheet, MSP430F5436AIPZR pinout, MSP430F5436AIPZR application, or MSP430F5436AIPZR equivalent, key selection criteria include standby current (1.7 µA in LPM3), wake-up time (3.5 µs), ADC resolution and channel count, USCI interface flexibility, and LQFP-100 package compatibility with existing TI MSP430F5xx layouts.

Technical Context

The MSP430F5436AIPZR implements a CPUXV2 core with constant generators for optimized code density and executes from flash at up to 25 MHz. Its unified clock system integrates FLL-based frequency stabilization, dual crystal support (32 kHz XT1 + up to 32 MHz XT2), VLO and REFO internal sources, and programmable LDO for core voltage regulation.

Peripherals are tightly synchronized via shared clock domains (MCLK, SMCLK, ACLK) and interrupt vectors mapped to 128 locations. The ADC12_A module supports autoscan across 16 channels with internal reference, sample-and-hold, and 200 ksps throughput; timers feature capture/compare shadow registers, PWM generation, and RTC alarm capability.

FAQ

What is the maximum system clock frequency supported by the MSP430F5436AIPZR?

The MSP430F5436AIPZR supports a maximum system clock (MCLK) frequency of 25 MHz, achieved using the FLL-controlled DCO with high-frequency crystal (XT2) up to 32 MHz or internal reference sources. This enables real-time processing of sensor data and communication protocols while maintaining ultra-low power consumption in active mode.

Does the MSP430F5436AIPZR include an integrated real-time clock (RTC)?

Yes, the MSP430F5436AIPZR includes the RTC_A module with calendar functionality, alarm capability, and dedicated 32-kHz crystal support (XIN/XOUT). It operates independently in LPM3 mode with only 1.7 µA current draw, allowing accurate timekeeping during extended sleep periods without CPU intervention.

How many analog input channels does the 12-bit ADC on the MSP430F5436AIPZR support?

The ADC12_A module on the MSP430F5436AIPZR supports 16 total channels: 14 external analog inputs (A0–A15, with A10/A11 reserved) and 2 internal channels (temperature sensor and VCC/2). All channels are accessible in autoscan mode with programmable sample-and-hold timing and internal reference voltage options.

Can the MSP430F5436AIPZR operate from a single 3.3-V supply?

Yes, the MSP430F5436AIPZR operates across a supply range of 1.8 V to 3.6 V. At 3.3 V, it delivers full performance: 25-MHz MCLK, 200-ksps ADC sampling, and all peripherals functional. Its integrated LDO allows stable VCORE regulation even with input supply variation, making it suitable for direct connection to standard 3.3-V rails.

Is the MSP430F5436AIPZR pin-compatible with other devices in the MSP430F543x family?

Yes, the MSP430F5436AIPZR in the LQFP-100 (PZ) package shares identical pinout and electrical characteristics with MSP430F5438AIPZR and MSP430F5419AIPZR. This enables drop-in replacement within the same package variant, preserving PCB layout, firmware peripheral mapping, and debug interface compatibility across memory- and feature-scaled variants.
