Product details
Overview
MSP430FR5987IRGCT from Texas Instruments is an ultra-low-power 16-bit FRAM microcontroller featuring 64KB nonvolatile memory, 2KB RAM, integrated 12-bit ADC with 12 external inputs, RTC with calendar mode, 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, supporting battery-powered water/heat meters and portable data loggers.
For engineers reviewing the MSP430FR5987IRGCT datasheet, MSP430FR5987IRGCT pinout, MSP430FR5987IRGCT application, or MSP430FR5987IRGCT equivalent, key selection criteria include FRAM endurance (1015 writes), ESI peripheral support for background analog sensing, LPM3.5 RTC current (0.35 µA), AES256 security coprocessor, and VQFN-64 package compatibility with capacitive touch I/O on all ports P1–P10 and PJ.
Technical Context
The MSP430FR5987IRGCT implements a 16-bit CPUXV2 core with seven low-power modes, including LPM3.5 (RTC active) and LPM4.5 (shutdown at 0.02 µA). Its clock system integrates DCO with 10 factory-trimmed frequencies, LFXT (32 kHz crystal), and HFXT support - enabling precise timing for metering real-time clocks and event-triggered wakeups.
Peripherals include three eUSCI modules (two UART/IrDA/SPI-capable eUSCI_A, one I2C/SPI-capable eUSCI_B), five 16-bit timers (TA0–TA3, TB0), 32-bit hardware multiplier, and CRC16/CRC32 engines. The ESI peripheral enables simultaneous multi-channel analog front-end scanning without CPU intervention - critical for ultrasonic flow measurement in utility meters.

The MSP430FR5987IRGCT supports a maximum system clock frequency of 16 MHz using its digitally controlled oscillator (DCO) with 10 factory-trimmed settings. This allows deterministic real-time processing for metrology algorithms while maintaining sub-100 µA/MHz active current efficiency - critical for meeting ANSI C12.20 and OIML R49 accuracy requirements in utility-grade meters.
Does the MSP430FR5987IRGCT include hardware encryption capabilities?
Yes, the MSP430FR5987IRGCT integrates a dedicated AES256 security coprocessor with true random number generation seed. This enables hardware-accelerated encryption/decryption of firmware images and sensor data - satisfying DLMS/COSEM security profiles and supporting secure boot and remote firmware updates without CPU overhead.
How does the Extended Scan Interface (ESI) in the MSP430FR5987IRGCT improve metering performance?
The ESI in the MSP430FR5987IRGCT performs autonomous analog signal acquisition across up to 16 channels - including ultrasonic transducer excitation, echo timing, and impedance measurement - without CPU intervention. This reduces active-mode duty cycle by >90%, extends battery life, and ensures deterministic timing for time-of-flight calculations essential in water and gas metering applications.
What is the RTC current consumption of the MSP430FR5987IRGCT in LPM3.5 mode?
The MSP430FR5987IRGCT consumes 0.35 µA typical in LPM3.5 mode with the real-time clock (RTC_C module) active and calendar functionality enabled. This ultra-low current enables decade-scale operation on primary lithium batteries - meeting IEC 62053-21 requirements for static electricity meters and EN 13757-3 for utility data concentrators.
Is the MSP430FR5987IRGCT pin-compatible with other devices in the MSP430FR59xx family?
Yes, the MSP430FR5987IRGCT in VQFN-64 (RGC) package shares identical pinout with MSP430FR5988IRGC and MSP430FR5989IRGC. This allows direct substitution within the same footprint for memory-scaling design flexibility - provided software accommodates differences in FRAM size and optional peripherals like LCD_C (not present in MSP430FR5987IRGCT).
