Product details
Overview
MSP430FR5887IPM from Texas Instruments is a 16-bit ultra-low-power FRAM microcontroller with 64KB nonvolatile memory, 2KB RAM, 12-bit ADC (12 external inputs), RTC with calendar, and extended scan interface (ESI) for metering applications. It operates from 1.8 V to 3.6 V and delivers 100 µA/MHz active current, 0.4 µA standby (LPM3), and 0.35 µA RTC mode (LPM3.5), targeting battery-powered water/heat meters.
For engineers reviewing the MSP430FR5887IPM datasheet, MSP430FR5887IPM pinout, MSP430FR5887IPM application, or MSP430FR5887IPM equivalent, key selection criteria include FRAM endurance (1015 writes), ESI peripheral for background analog sensing, LQFP-64 package compatibility, and UART/I²C serial interfaces with hardware bootloader support.
Technical Context
The MSP430FR5887IPM integrates a 16-bit CPUXV2 core with up to 16-MHz DCO clock, three-channel DMA, and dual eUSCI modules (eUSCI_A0/A1 for UART/IrDA/SPI; eUSCI_B0/B1 for I²C/SPI). Its clock system supports LFXT (32 kHz crystal), HFXT (up to 24 MHz), and VLO for low-power timing.
It features an Extended Scan Interface (ESI) with dedicated analog front-end for capacitive or resistive sensor measurement without CPU intervention, plus integrated LCD driver supporting up to 48 segments - distinct from higher-pin-count MSP430FR68xx variants that support 320-segment displays.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power FRAM microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430FR5889IPM | 128KB FRAM, same 64-pin LQFP package, identical peripheral set except larger memory | Required where >64KB persistent data storage is needed for extended logging or firmware-over-the-air staging | Select when future-proofing memory capacity without PCB change; pinout and software are fully compatible |
| MSP430FR5969IPM | 64KB FRAM but adds AES-128 encryption engine and enhanced ESI with more channels; same LQFP-64 package | Suitable for applications requiring cryptographic data integrity (e.g., utility meter firmware validation or secure sensor data) | Choose when security compliance (e.g., DLMS/COSEM) mandates hardware crypto acceleration beyond basic FRAM persistence |
Compared with MSP430FR5889IPM and MSP430FR5969IPM, the MSP430FR5887IPM provides optimal cost/power balance for metering applications where 64KB FRAM suffices and hardware encryption is not required, while retaining full pin and software compatibility within the MSP430FR58xx family.

FAQ
What is the maximum operating frequency of the MSP430FR5887IPM?
The MSP430FR5887IPM supports a maximum system clock frequency of 16 MHz using its digitally controlled oscillator (DCO) or external high-frequency crystal (HFXT). This frequency is achievable across the full 1.8 V to 3.6 V supply range, with timing specifications validated per datasheet Section 5.13.
Does the MSP430FR5887IPM include hardware encryption capabilities?
No, the MSP430FR5887IPM does not integrate an AES encryption engine. Hardware crypto acceleration is present in the MSP430FR59xx series (e.g., MSP430FR5969IPM) but omitted in the MSP430FR5887IPM to optimize cost and power for metering applications where secure boot or encrypted communication is handled externally.
How many external ADC input channels does the MSP430FR5887IPM support?
The MSP430FR5887IPM supports 12 external analog input channels for its 12-bit ADC12_B module, as confirmed in Table 3-1 of the SLASE32C datasheet. It does not support the 16-channel configuration found in MSP430FR68xx devices due to package and peripheral constraints in the 64-pin variant.
What LCD segment count is supported by the MSP430FR5887IPM?
The MSP430FR5887IPM integrates an LCD_C module supporting up to 48 segments, as specified in Table 3-1 of the SLASE32C datasheet. This is half the 96-segment capability of the MSP430FR6887 and reflects the reduced I/O count and LCD driver resources in the 64-pin LQFP package.
Is the MSP430FR5887IPM pin-compatible with the MSP430FR5889IPM?
Yes, the MSP430FR5887IPM and MSP430FR5889IPM share identical 64-pin LQFP (PM) packaging, pinout, and peripheral mapping. The only functional difference is FRAM size (64KB vs. 128KB); all registers, interrupts, and memory layout above 64KB are reserved in the MSP430FR5887IPM, ensuring full hardware and software compatibility.
