Product details
Overview
MSP430FR5889IRGCR from Texas Instruments is an ultra-low-power 16-bit FRAM microcontroller featuring 128KB nonvolatile FRAM, 2KB RAM, 16-MHz CPU, integrated 12-bit ADC with 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, 0.35 µA RTC mode, and 0.02 µA shutdown current - optimized for battery-powered water/heat meters and portable data loggers.
For engineers reviewing the MSP430FR5889IRGCR datasheet, MSP430FR5889IRGCR pinout, MSP430FR5889IRGCR application, or MSP430FR5889IRGCR equivalent, key selection criteria include FRAM endurance (1015 writes), ESI peripheral support for capacitive fluid/gas sensing, LPM3.5 RTC operation, 64-pin VQFN package (9 mm × 9 mm), and UART/I²C/SPI dual eUSCI modules.
Technical Context
The MSP430FR5889IRGCR implements the ULP CPUXV2 core with seven low-power modes, including LPM3.5 (RTC active, 0.35 µA) and LPM4.5 (0.02 µA). Its clock system integrates DCO (10 factory-trimmed frequencies), LFXT (32-kHz crystal), and HFXT (high-frequency crystal) sources, enabling precise timing control across power states.
Peripherals include three 16-bit Timer_A modules (TA0–TA3), one 16-bit Timer_B (TB0), 32-bit hardware multiplier, three-channel DMA, CRC16/CRC32 engines, and ESI for background analog signal acquisition - all accessible via multiplexed I/O on 48 GPIO pins in the RGC package.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430FR5889IPM | LQFP-64 package (10 mm × 10 mm), no exposed thermal pad, identical electrical specs and pinout mapping | Better suited for through-hole prototyping or legacy PCB layouts requiring larger pitch and manual soldering | Select when thermal pad assembly is not feasible or when board rework tolerance is prioritized over size |
| MSP430FR58891IRGCR | Identical package and FRAM/RAM specs, but features I²C-based hardware bootloader (BSL) instead of UART BSL | Required where secure field updates via I²C master devices (e.g., PMICs or companion SoCs) are mandated | Choose when system architecture mandates I²C BSL compatibility and UART pins must remain free for application use |
Compared with MSP430FR5889IPM, the MSP430FR5889IRGCR offers superior thermal performance via its exposed pad and smaller footprint; versus MSP430FR58891IRGCR, it provides UART BSL for simpler host-side programming but requires dedicated UART pins.

FAQ
What is the maximum operating frequency of the MSP430FR5889IRGCR?
The MSP430FR5889IRGCR supports a maximum CPU clock frequency of 16 MHz, achieved via its factory-trimmed DCO or external HFXT crystal. This allows real-time execution of complex metering algorithms while maintaining ultra-low-power operation in active mode (100 µA/MHz).
Does the MSP430FR5889IRGCR support hardware encryption?
No, the MSP430FR5889IRGCR does not include AES or other hardware encryption accelerators. Security relies on software-based implementations or external secure elements; however, its MPU (Memory Protection Unit) and IP encapsulation provide basic code protection against unauthorized access.
How many I/O pins are available on the MSP430FR5889IRGCR in the RGC package?
The MSP430FR5889IRGCR in the 64-pin VQFN (RGC) package provides 48 general-purpose I/O pins across ports P1–P9 and PJ, all supporting capacitive touch sensing without external components - ideal for compact HMI designs in utility meters.
What is the purpose of the ESIDVCC and ESIDVSS pins on the MSP430FR5889IRGCR?
The ESIDVCC and ESIDVSS pins supply isolated power and ground to the Extended Scan Interface (ESI) subsystem. This separation prevents digital noise from affecting high-precision capacitive measurements - essential for stable ESI operation in water/heat metering applications.
Can the MSP430FR5889IRGCR drive an LCD display directly?
No, the MSP430FR5889IRGCR lacks an integrated LCD_C module. Unlike the MSP430FR6889, this variant omits LCD driver support - confirmed by device comparison tables showing "N/A" for LCD_C in MSP430FR5889 rows. External LCD controllers or segment drivers are required.
