Product details
Overview
MSP430FR5888IRGCR from Texas Instruments is a 16-bit ultra-low-power FRAM microcontroller with 96KB nonvolatile memory, 2KB RAM, 12-bit ADC (12 external inputs), RTC, 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, 0.35 µA RTC mode, and supports capacitive touch on all I/O ports.
For engineers reviewing the MSP430FR5888IRGCR datasheet, MSP430FR5888IRGCR pinout, MSP430FR5888IRGCR application, or MSP430FR5888IRGCR equivalent, key selection criteria include ESI peripheral support for ultrasonic flow sensing, FRAM endurance (10¹⁵ write cycles), LPM3.5 RTC operation, 64-pin VQFN package thermal performance, and UART/I²C dual-BSL compatibility.
Technical Context
The MSP430FR5888IRGCR integrates a 16-bit CPUXV2 core with FRAM-based unified memory architecture, enabling simultaneous code execution and data logging without erase latency. Its clock system combines DCO (up to 16 MHz), LFXT (32 kHz crystal), and HFXT (4–24 MHz crystal) sources, with automatic clock gating per peripheral domain.
Peripherals include three eUSCI modules (eUSCI_A0/A1 for UART/IrDA/SPI; eUSCI_B0/B1 for I²C/SPI), five 16-bit timers (TA0–TA3, TB0), CRC16/CRC32 accelerators, and an ESI subsystem optimized for background analog front-end acquisition in water/heat meters - supporting up to 16-channel differential capacitance or impedance measurement without CPU intervention.

FAQ
What is the maximum operating frequency of the MSP430FR5888IRGCR?
The MSP430FR5888IRGCR supports a maximum system clock frequency of 16 MHz via its factory-trimmed DCO or external HFXT crystal. This allows real-time execution of ESI timing-critical ultrasonic pulse generation and echo capture sequences while maintaining sub-100 µA/MHz active power efficiency - verified in TI's SLASE32C datasheet Section 5.13.
Does the MSP430FR5888IRGCR support hardware-based encryption?
The MSP430FR5888IRGCR does not integrate AES or dedicated cryptographic accelerators. However, it provides a true random number seed generator for secure algorithm initialization and MPU-based IP encapsulation to protect firmware regions - sufficient for basic data integrity in utility metering per EN 13757-3, though external secure elements are recommended for advanced key management.
Can the MSP430FR5888IRGCR drive an LCD display?
No, the MSP430FR5888IRGCR omits the LCD_C peripheral present in MSP430FR68xx devices. Its pinout and functional block diagram confirm absence of LCD segment drivers and COM line outputs - making it unsuitable for direct LCD interfacing. Designs requiring display must use companion drivers or select MSP430FR6888 variants.
What is the purpose of the ESIDVCC and ESIDVSS pins on the MSP430FR5888IRGCR?
The ESIDVCC and ESIDVSS pins provide a dedicated analog power domain for the Extended Scan Interface (ESI) subsystem. They must be decoupled independently from the main DVCC/DVSS rails using low-ESR ceramic capacitors to prevent digital switching noise from degrading ESI's ultrasonic echo timing resolution - a requirement explicitly stated in TI's SLASE32C datasheet Section 7.2.2.
Is the MSP430FR5888IRGCR pin-compatible with the MSP430FR5889IRGCR?
Yes, the MSP430FR5888IRGCR and MSP430FR5889IRGCR share identical VQFN-64 (RGC) packaging, pinout, and peripheral mapping. The only functional difference is FRAM capacity (96KB vs 128KB); all registers, memory maps, and interrupt vectors remain binary-compatible - enabling drop-in replacement where memory headroom permits.
