Texas Instruments MSP430F5436IPZ

Overview

MSP430F5436IPZ from Texas Instruments is a 16-bit ultra-low-power mixed-signal microcontroller in 100-pin LQFP (PZ) package, featuring 192 KB flash, 16 KB RAM, 12-bit ADC with 14 external + 2 internal channels, three 16-bit timers (TA0/TA1/TB0), and four USCI modules supporting UART/IrDA/SPI/I²C. It operates from 2.2 V to 3.6 V and targets battery-powered sensor systems requiring fast wake-up (<5 µs) and RTC functionality.

For engineers reviewing the MSP430F5436IPZ datasheet, MSP430F5436IPZ pinout, MSP430F5436IPZ application, or MSP430F5436IPZ equivalent, key selection criteria include its 100-pin LQFP footprint, 87 GPIOs, integrated LDO core regulator, unified clock system with FLL and multiple oscillator sources (XT1, XT2, REFO, VLO), and support for real-time clock with alarm capability.

Technical Context

The MSP430F5436IPZ implements the CPUXV2 16-bit RISC core with constant generators and extended memory addressing, enabling efficient C code execution. Its power management includes five low-power modes (LPM0–LPM4), programmable core voltage via integrated LDO, and supply supervision with brownout reset.

The Unified Clock System (UCS) supports simultaneous operation of multiple clock domains (MCLK, SMCLK, ACLK), with FLL-based stabilization of DCO frequency up to 18 MHz, plus independent low-frequency sources (32-kHz crystal, REFO, VLO) for RTC and low-power timing.

FAQ

What is the maximum system clock frequency supported by the MSP430F5436IPZ?

The MSP430F5436IPZ supports a maximum system clock (MCLK) frequency of 18 MHz, achieved via the digitally controlled oscillator (DCO) stabilized by the FLL loop within the Unified Clock System. This frequency is confirmed in Section 1.1 Features and Section 5.20 (DCO Frequency) of the SLAS612F datasheet. The MSP430F5436IPZ maintains timing integrity at this speed while operating within its 2.2–3.6 V supply range and specified temperature limits.

Does the MSP430F5436IPZ include an integrated real-time clock (RTC) module?

Yes, the MSP430F5436IPZ includes a dedicated RTC_A module with calendar functionality, alarm capability, and support for 32.768 kHz crystal operation. As documented in Section 1.1 Features and Figure 1-1, the RTC remains fully operational in Standby Mode (LPM3) with full RAM retention and consumes only 2.6 µA at 3.0 V. The P2.4 pin outputs RTCCLK, and the module integrates calibration and compensation features for long-term accuracy.

How many universal serial communication interfaces (USCI) does the MSP430F5436IPZ provide, and what protocols do they support?

The MSP430F5436IPZ provides four USCI modules: USCI_A0 through A3 support UART, IrDA, and SPI; USCI_B0 through B3 support I²C and SPI. This configuration is explicitly stated in Section 1.1 Features and Table 3-1 (Device Comparison). Each USCI_A channel handles asynchronous and synchronous modes independently, while each USCI_B channel supports multimaster I²C and full-duplex SPI-enabling concurrent wired communication with sensors, displays, and radios without resource conflict.

What is the ADC resolution and input channel count for the MSP430F5436IPZ?

The MSP430F5436IPZ integrates a 12-bit successive approximation register (SAR) ADC (ADC12_A) with 14 external analog input channels and 2 internal channels (temperature sensor and VREF/2), totaling 16 selectable inputs. Its maximum sampling rate is 200 ksps, and it supports autoscan mode for unattended multi-channel acquisition. These specifications are verified in Section 1.1 Features, Table 3-1, and Section 5.36–5.41 of the SLAS612F datasheet.

Is the MSP430F5436IPZ pin-compatible with other devices in the MSP430F543x PZ-package family?

Yes, the MSP430F5436IPZ is pin-compatible with MSP430F5438IPZ and MSP430F5419IPZ in the 100-pin LQFP (PZ) package, as confirmed by Figure 4-1 ("100-Pin PZ Package – MSP430F5438IPZ, MSP430F5436IPZ, MSP430F5419IPZ") and Table 4-1 (Signal Descriptions) in SLAS612F. All share identical pin numbering, signal assignments, and electrical characteristics-enabling hardware reuse across variants differentiated only by flash size (128/192/256 KB) and feature enablement.
