Product details

Overview

MSP430FR6888IPNR from Texas Instruments is a 16-bit ultra-low-power FRAM microcontroller featuring 128KB nonvolatile FRAM, 2KB RAM, 12-bit ADC with 16 external inputs, integrated LCD driver for up to 320 segments, and real-time clock with calendar function. It operates from 1.8 V to 3.6 V and supports seven low-power modes including LPM4.5 (0.02 µA typical), targeting battery-powered utility metering and data logging systems.

For engineers reviewing the MSP430FR6888IPNR datasheet, MSP430FR6888IPNR pinout, MSP430FR6888IPNR application, or MSP430FR6888IPNR equivalent, key selection considerations include FRAM endurance (10¹⁵ write cycles), RTC-backed low-power operation (0.35 µA in LPM3.5), integrated capacitive touch I/O on all ports P1–P10/PJ, and dual eUSCI modules supporting UART/IrDA/SPI/I²C with hardware bootloader.

Technical Context

The MSP430FR6888IPNR implements the MSP430 CPUXV2 core with 16 registers and executes instructions at up to 16 MHz using a factory-trimmed DCO or external HFXT/LFXT crystals. Its memory subsystem unifies program, data, and storage in a single FRAM space, eliminating erase-before-write delays and enabling atomic writes critical for energy-harvested or interrupt-driven metering firmware.

Peripherals are tightly coupled to low-power domains: the RTC_C module operates independently in LPM3.5, the LCD_C driver supports static and 2–8-mux configurations with contrast control, and five 16-bit timers (three Timer_A, two Timer_B) provide capture/compare resources across 32 total CCR registers - with dedicated outputs routed to COM/SEG pins for direct LCD drive.

Equivalent & Alternatives

The following parts are listed as comparable options for similar microcontroller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MSP430FR6879IPN	Same FRAM (128KB), RAM (2KB), and peripherals but lacks integrated LCD_C driver and supports only up to 240 LCD segments.	Suitable for non-display applications or designs using external LCD controllers; lower pin count (80 vs. 80) but reduced segment drive capability.	Select when LCD functionality is unnecessary or handled externally; identical package and footprint simplify migration if display is later added.
MSP430FR6989IPZ	100-pin LQFP package with 128KB FRAM, 2KB RAM, and LCD_C supporting 320 segments - adds AES-128 encryption engine and enhanced DMA.	Required for applications needing cryptographic data protection (e.g., secure utility meter firmware updates or HIPAA-compliant medical logs).	Choose when hardware security acceleration is mandatory; larger package (100-pin) requires PCB redesign but provides future-proofing for encrypted communications.

Compared with MSP430FR6879IPN, the MSP430FR6888IPNR delivers full 320-segment LCD drive and identical FRAM endurance, while MSP430FR6989IPZ adds AES-128 and expands timer resources - making the MSP430FR6888IPNR optimal for cost-sensitive, display-centric metering where security is secondary to power and integration.

FAQ

What is the maximum operating frequency of the MSP430FR6888IPNR?

The MSP430FR6888IPNR supports a maximum system clock frequency of 16 MHz, achieved using the factory-trimmed DCO oscillator or external high-frequency crystal (HFXT). This speed is fully supported across the entire 1.8 V to 3.6 V supply range, enabling real-time metrology calculations without performance throttling at low battery voltage.

Does the MSP430FR6888IPNR support hardware encryption?

No, the MSP430FR6888IPNR does not include a hardware AES engine. Encryption must be implemented in software using its 32-bit hardware multiplier (MPY) and FRAM-resident code. For hardware-accelerated cryptography, consider the MSP430FR6989IPZ, which integrates AES-128.

How many LCD segments can the MSP430FR6888IPNR drive?

The MSP430FR6888IPNR's LCD_C module supports up to 320 segments in static, 2-, 3-, 4-, 6-, or 8-mux configurations. This matches the capability documented for the MSP430FR6879 family and is confirmed in the device comparison table for the 80-pin PN package variant.

What is the standby current consumption of the MSP430FR6888IPNR?

In Standby mode (LPM3 with VLO enabled), the MSP430FR6888IPNR consumes 0.4 µA typical. When combined with RTC operation (LPM3.5), current rises to 0.35 µA typical - both values measured at 3 V and 25°C per the SLASE33C datasheet revision August 2018.

Is the MSP430FR6888IPNR pin-compatible with other MSP430FR68xx devices?

Yes, the MSP430FR6888IPNR shares the same 80-pin LQFP (PN) package, pinout, and electrical characteristics with MSP430FR6879IPN and MSP430FR6877IPN. Functionally identical peripherals and memory maps allow drop-in replacement where LCD segment count and BSL type align.
