Product details

Overview

MSP430FR5888IRGCT from Texas Instruments is an ultra-low-power 16-bit FRAM microcontroller designed for battery-operated metering and sensing applications. It integrates 96KB of nonvolatile FRAM, 2KB RAM, a 12-bit ADC with 12 external inputs, RTC with calendar, and Extended Scan Interface (ESI) for capacitive sensing in water/heat meters. Operating from 1.8 V to 3.6 V, it achieves 0.35 µA RTC current in LPM3.5 mode.

For engineers reviewing the MSP430FR5888IRGCT datasheet, MSP430FR5888IRGCT pinout, MSP430FR5888IRGCT application, or MSP430FR5888IRGCT equivalent, key selection criteria include ESI peripheral support, FRAM endurance (10¹⁵ write cycles), 64-pin VQFN package thermal performance, and compatibility with TI's EnergyTrace++ development tools.

Technical Context

The MSP430FR5888IRGCT implements the ULP CPUXV2 core with seven low-power modes, including LPM3.5 (RTC active) and LPM4.5 (shutdown at 0.02 µA). Its clock system combines DCO, LFXT (32 kHz crystal), and HFXT (up to 24 MHz) with automatic frequency calibration.

It features three eUSCI modules (two UART/IrDA/SPI-capable eUSCI_A, one I²C/SPI-capable eUSCI_B), a 32-bit hardware multiplier, three-channel DMA, and dual 16-bit Timer_A (3+3 capture/compare registers) plus one Timer_B (2+5 registers) - all optimized for deterministic real-time control in energy-constrained systems.

FAQ

What is the maximum operating frequency of the MSP430FR5888IRGCT?

The MSP430FR5888IRGCT supports a maximum system clock frequency of 16 MHz via its digitally controlled oscillator (DCO) or external HFXT crystal. This allows real-time processing of ESI sensor data and ADC conversions while maintaining sub-100 µA/MHz active current efficiency - essential for responsive user interfaces in heat cost allocators.

Does the MSP430FR5888IRGCT support hardware encryption?

No, the MSP430FR5888IRGCT does not include dedicated AES or SHA hardware accelerators. It relies on software-based cryptographic libraries for secure boot or data signing. For applications requiring hardware crypto, consider the MSP430FR5994 or later FRAM devices with integrated AES-128 modules.

What package type is used for the MSP430FR5888IRGCT?

The MSP430FR5888IRGCT uses a 64-pin VQFN package (RGC suffix), measuring 9 mm × 9 mm with an exposed thermal pad. This package supports automated optical inspection and offers superior thermal resistance (θ_JA ≈ 42°C/W) compared to TSSOP alternatives - critical for sustained ESI operation in sealed meter enclosures.

Can the MSP430FR5888IRGCT drive an LCD display directly?

Yes, the MSP430FR5888IRGCT integrates the LCD_C peripheral supporting up to 48 segments in static mode or 320 segments in multiplexed configurations. Its P6.x pins generate regulated LCD bias voltages (V1–V5), eliminating external charge pumps and reducing bill-of-materials cost in heat meter displays.

What is the write endurance specification for the FRAM in the MSP430FR5888IRGCT?

The FRAM in the MSP430FR5888IRGCT is rated for 10¹⁵ write cycles - orders of magnitude higher than flash or EEPROM. This enables frequent timestamped logging (e.g., every 15 seconds) for over 47,000 years without memory wear-out, making it ideal for lifetime data integrity in utility infrastructure deployments.
