Texas Instruments MSP430FR5887IPMR

Overview

MSP430FR5887IPMR from Texas Instruments is a 16-bit ultra-low-power FRAM microcontroller designed for battery-powered metering and sensing applications. It integrates 64KB of nonvolatile FRAM, 2KB RAM, a 12-bit ADC with 12 external inputs, RTC with calendar, five 16-bit timers, and an Extended Scan Interface (ESI) for capacitive sensing in water/heat meters. Operates from 1.8 V to 3.6 V with active current as low as 100 µA/MHz.

For engineers reviewing the MSP430FR5887IPMR datasheet, MSP430FR5887IPMR pinout, MSP430FR5887IPMR application, or MSP430FR5887IPMR equivalent, key selection criteria include FRAM endurance (10¹⁵ writes), ESI peripheral support for background analog measurement, LPM3.5 RTC current (0.35 µA), and 64-pin LQFP package compatibility with capacitive touch I/O on all ports P1–P10 and PJ.

Technical Context

The MSP430FR5887IPMR implements the MSP430 CPUXV2 core with 16 general-purpose registers and supports seven low-power modes optimized for energy-constrained deployments. Its clock system includes DCO (factory-trimmed at 10 frequencies), LFXT (32-kHz crystal), HFXT (up to 24 MHz), and VLO - enabling precise timing control across sleep/wake cycles.

Peripherals are tightly coupled to power domains: the ESI operates autonomously during LPM3.5 for continuous sensor scanning without CPU wake-up; the 12-bit ADC12_B supports internal reference and sample-and-hold; and dual eUSCI modules provide UART/IrDA/SPI (eUSCI_A) and I²C/SPI (eUSCI_B) with hardware bootloader support.

FAQ

What is the maximum operating frequency of the MSP430FR5887IPMR?

The MSP430FR5887IPMR supports a maximum system clock frequency of 16 MHz via its digitally controlled oscillator (DCO), which is factory-trimmed at 10 selectable frequencies. This enables deterministic real-time execution for time-critical metrology tasks such as ultrasonic transit-time calculations or ESI scan sequencing without requiring external high-frequency crystals.

Does the MSP430FR5887IPMR support hardware encryption?

No, the MSP430FR5887IPMR does not include a hardware AES engine. It relies on software-based cryptographic libraries for basic security functions. For applications requiring hardware-accelerated encryption, consider the MSP430FR5969IPM - a pin-compatible alternative with integrated AES-128. The MSP430FR5887IPMR prioritizes ultra-low-power analog sensing and FRAM endurance over cryptographic acceleration.

How many external ADC input channels does the MSP430FR5887IPMR support?

The MSP430FR5887IPMR integrates the ADC12_B module with support for up to 12 external analog input channels. These are mapped to dedicated pins including P1.0–P1.5, P9.0–P9.7 (A8–A15), and other configurable analog-capable I/O. The ADC includes internal reference, sample-and-hold, and programmable conversion timing - optimized for precision metrology signal chains.

What package type and dimensions does the MSP430FR5887IPMR use?

The MSP430FR5887IPMR uses a 64-pin LQFP (PM) package measuring 10 mm × 10 mm with 0.5-mm lead pitch. It features an exposed thermal pad on the underside, which TI recommends connecting directly to VSS for optimal thermal performance and EMI reduction in high-precision analog designs.

Is the MSP430FR5887IPMR compatible with the MSP430FR5889IPM pinout?

Yes, the MSP430FR5887IPMR and MSP430FR5889IPM share identical 64-pin LQFP (PM) packaging and fully compatible pinouts - including identical signal assignments for power, ground, reset, JTAG, ESI, ADC, timers, and serial interfaces. This allows direct substitution in existing designs when increased FRAM capacity (128KB vs. 64KB) is required without PCB revision.
