Texas Instruments MSP430F5436AIPZ

Overview

MSP430F5436AIPZ from Texas Instruments is a 16-bit ultra-low-power mixed-signal microcontroller featuring 192 KB flash, 16 KB RAM, a 12-bit ADC with 14 external channels, four USCI modules (UART/IrDA/SPI/I²C), and three 16-bit timers - deployed in battery-powered sensor systems, digital thermostats, and handheld meters requiring sub-2 µA standby current and 3.5 µs wake-up.

For engineers reviewing the MSP430F5436AIPZ datasheet, MSP430F5436AIPZ pinout, MSP430F5436AIPZ application, or MSP430F5436AIPZ equivalent, key selection criteria include LPM3 current (1.7 µA @ 2.2 V), 100-pin LQFP package compatibility, RTC integration, and dual-USCI support for concurrent UART + I²C communication in space-constrained embedded designs.

Technical Context

The MSP430F5436AIPZ implements a CPUXV2 core with constant generators and extended memory addressing, enabling efficient C code execution. Its unified clock system integrates FLL-based frequency stabilization, programmable LDO regulation, and multiple clock sources (XT1, XT2, REFO, VLO) to support dynamic voltage and frequency scaling across active and low-power modes.

Peripherals are tightly synchronized via shared clock domains: SMCLK drives Timer_A/B and USCI modules; ACLK feeds RTC and ADC; MCLK powers CPU and DMA. The 3-channel DMA engine enables zero-CPU-overhead data transfers between ADC, USCI, and memory - critical for continuous sensor acquisition without interrupt latency penalties.

FAQ

What is the maximum system clock frequency supported by the MSP430F5436AIPZ?

The MSP430F5436AIPZ supports a maximum system clock frequency of 25 MHz, achieved via its digitally controlled oscillator (DCO) with FLL stabilization. This frequency is confirmed in the device's electrical specifications and functional block diagram, enabling high-speed signal processing while maintaining ultra-low-power operation through dynamic clock gating and low-power modes.

Does the MSP430F5436AIPZ include an integrated real-time clock (RTC)?

Yes, the MSP430F5436AIPZ includes a dedicated RTC_A module with calendar functionality, alarm capability, and independent 32-kHz crystal support (XT1). It operates in LPM3 with only 1.7 µA current draw, retains full RAM, and provides timestamping and scheduled wake-up - all verified in the device description, functional block diagram, and low-power mode specifications.

How many universal serial communication interfaces (USCIs) does the MSP430F5436AIPZ have, and what protocols do they support?

The MSP430F5436AIPZ has four USCIs: USCI_A0/A1/A2/A3 support UART, IrDA, and SPI; USCI_B0/B1/B2/B3 support I²C and SPI. This configuration is explicitly stated in the Features section and confirmed in Table 6-1 (Device Characteristics), enabling concurrent UART + I²C communication without protocol conflict or resource contention.

What is the ADC resolution and channel count on the MSP430F5436AIPZ?

The MSP430F5436AIPZ features a 12-bit successive approximation register (SAR) ADC (ADC12_A) with 14 external analog input channels and 2 internal channels (temperature sensor and VCC/2). This specification is documented in the Features list, functional block diagram, and Device Comparison table - supporting high-accuracy sensor measurements across diverse analog front-end configurations.

Is the MSP430F5436AIPZ pin-compatible with other devices in the MSP430F543x family?

Yes, the MSP430F5436AIPZ shares identical pinout and package (100-pin LQFP, PZ) with MSP430F5438AIPZ and MSP430F5419AIPZ, as confirmed in Figure 7-1 and Table 6-1. All three devices use the same terminal numbering, signal mapping, and mechanical dimensions - enabling hardware reuse across variants with differing flash sizes.
