Product details
Overview
MSP430FR5887IRGCT from Texas Instruments is an ultra-low-power 16-bit 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 supports LPM3.5 standby at 0.35 µA typical - deployed in water/heat meters requiring long-life battery operation and high-reliability data logging.
For engineers reviewing the MSP430FR5887IRGCT datasheet, MSP430FR5887IRGCT pinout, MSP430FR5887IRGCT application, or MSP430FR5887IRGCT equivalent, key selection criteria include ESI peripheral support, FRAM endurance (10¹⁵ write cycles), integrated LCD driver (up to 48 segments), 64-pin VQFN package thermal performance, and UART/I²C bootloader compatibility.
Technical Context
The MSP430FR5887IRGCT implements a 16-bit CPUXV2 core with hardware multiplier and three-channel DMA, enabling deterministic real-time processing for metrology firmware. Its clock system integrates DCO (10 factory-trimmed frequencies), LFXT (32-kHz crystal), and HFXT (high-frequency crystal) sources, with automatic clock fail-safe switching.
It features dual USCI modules: eUSCI_A0/A1 supporting UART (with auto-baud detection), IrDA, and SPI; eUSCI_B0/B1 supporting I²C (multi-slave addressing) and SPI. The ESI peripheral enables background capacitive sensing for fluid/gas volume measurement without CPU intervention.

FAQ
What is the maximum operating frequency of the MSP430FR5887IRGCT?
The MSP430FR5887IRGCT supports a maximum system clock frequency of 16 MHz via its digitally controlled oscillator (DCO), with 10 factory-trimmed frequency settings. This allows deterministic real-time execution of metrology algorithms while maintaining ultra-low active-mode current of approximately 100 µA/MHz - critical for balancing computational throughput and battery longevity in sealed meter enclosures.
Does the MSP430FR5887IRGCT support hardware encryption?
No, the MSP430FR5887IRGCT does not include hardware AES or cryptographic accelerators. It relies on software-based security primitives. For designs requiring FIPS 140-2 or DLMS/COSEM compliance, TI recommends the MSP430FR5969IPM, which integrates AES-128. The MSP430FR5887IRGCT prioritizes ESI, FRAM endurance, and sub-µA RTC operation over cryptographic functionality.
What is the purpose of the ESI peripheral in the MSP430FR5887IRGCT?
The Extended Scan Interface (ESI) in the MSP430FR5887IRGCT is a dedicated hardware peripheral for capacitive sensing, supporting up to 16 input channels with background operation. It enables precise fluid level, flow, or proximity detection in water/heat meters without CPU intervention - reducing active time and extending battery life. ESI integrates charge-transfer measurement, automatic calibration, and noise rejection optimized for industrial environments.
Can the MSP430FR5887IRGCT drive an LCD display?
Yes, the MSP430FR5887IRGCT integrates an LCD_C peripheral supporting up to 48 segments with static or 2–4 multiplex configurations. It includes programmable contrast control and internal charge pump, eliminating the need for external bias circuitry. This capability is commonly used in local displays for heat cost allocators and portable utility meters where space and bill-of-materials are constrained.
What bootloading options are supported by the MSP430FR5887IRGCT?
The MSP430FR5887IRGCT supports hardware UART-based bootloader (BSL) accessible via P2.0 (BSLTX) and P2.1 (BSLRX). It does not support I²C BSL - that variant is designated MSP430FR58871. The UART BSL enables field firmware updates over standard serial interfaces without requiring JTAG debug hardware, simplifying maintenance for deployed metering infrastructure.
