Product details
Overview
MSP430FR6888IPZR from Texas Instruments is a 16-bit ultra-low-power FRAM microcontroller featuring 128KB nonvolatile FRAM, 2KB RAM, integrated 12-bit ADC with 16 external inputs, LCD driver supporting up to 320 segments, and real-time clock with calendar/alarm. It operates from 1.8 V to 3.6 V and delivers 100 µA/MHz active current, targeting battery-powered metering applications.
For engineers reviewing the MSP430FR6888IPZR datasheet, MSP430FR6888IPZR pinout, MSP430FR6888IPZR application, or MSP430FR6888IPZR equivalent, key selection criteria include FRAM endurance (1015 write cycles), LPM3.5 RTC current (0.35 µA), 100-pin LQFP package compatibility, and dual eUSCI_A/eUSCI_B serial interfaces for UART/I²C/SPI coexistence in constrained-energy systems.
Technical Context
The MSP430FR6888IPZR implements the MSP430 CPUXV2 core with 16 registers and integrates a flexible clock system including DCO (10 factory-trimmed frequencies), LFXT (32-kHz crystal), and HFXT support. Its memory architecture unifies FRAM for code, data, and storage - eliminating separate flash/EEPROM partitions and enabling atomic writes without erase cycles.
Peripherals include three 16-bit Timer_A modules (TA0/TA1/TA3), two Timer_B modules (TB0/TB1), 32-bit hardware multiplier, three-channel DMA, CRC16/CRC32 engines, and capacitive touch I/O across all ports P1–P10 and PJ without external components. The device supports hardware UART and I²C bootloader (BSL) via dedicated eUSCI modules.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power FRAM microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430FR6879IPZR | 128KB FRAM, same 100-pin LQFP package, identical peripheral set except TA3 has 5 capture/compare registers vs. MSP430FR6888IPZR's TA3 with 2 registers. | Targeted at metering with identical LCD/RTC/ADC specs; lacks TA3 extended CCR count for complex PWM timing. | Select when full TA3 register count is unnecessary and legacy design reuse is prioritized. |
| MSP430FR6989IPZ | 128KB FRAM, 100-pin LQFP, adds AES-128 encryption engine and enhanced BSL security features; otherwise matches core peripherals. | Suitable for secure AMR deployments requiring encrypted data transmission or firmware authentication. | Choose when cryptographic acceleration or secure boot is mandated by utility regulatory requirements. |
Compared with MSP430FR6879IPZR, the MSP430FR6888IPZR offers identical FRAM, RTC, and LCD capabilities but includes an additional Timer_A module (TA3) with expanded capture/compare resources for advanced metrology timing; versus MSP430FR6989IPZ, it omits AES but maintains lower power profile and cost for non-secure metering endpoints.

FAQ
What is the maximum operating frequency of the MSP430FR6888IPZR?
The MSP430FR6888IPZR supports a maximum system clock frequency of 16 MHz via its digitally controlled oscillator (DCO) with 10 factory-trimmed settings. This allows high-speed computation during active mode while maintaining sub-µA currents in low-power modes. The MSP430FR6888IPZR also supports external HFXT crystals for precise timing-critical applications such as metrology sampling.
Does the MSP430FR6888IPZR support hardware encryption?
No, the MSP430FR6888IPZR does not include a hardware AES engine. Unlike the MSP430FR69xx series, this device focuses on ultra-low-power metering without cryptographic acceleration. For secure firmware updates or encrypted communication, software-based AES implementations or external crypto co-processors must be used alongside the MSP430FR6888IPZR.
How many LCD segments can the MSP430FR6888IPZR drive?
The MSP430FR6888IPZR integrates the LCD_C module capable of driving up to 320 segments in static, 2-, 3-, 4-, 6-, or 8-mux configurations. Its 8 COM outputs (COM0–COM7) and extensive SEG pin mapping across P1–P10 and PJ ports allow flexible display layouts for utility meters and portable instruments without external drivers.
What is the FRAM endurance specification for the MSP430FR6888IPZR?
The MSP430FR6888IPZR features 1015 write cycles per FRAM location - orders of magnitude higher than flash or EEPROM. This enables continuous logging, firmware patching, and parameter storage in field-deployed devices without wear-out concerns. Each 16-bit word write completes in 125 ns, allowing 64 KB FRAM to be written in under 4 ms.
Is the MSP430FR6888IPZR pin-compatible with other MSP430FR68xx devices?
Yes, the MSP430FR6888IPZR shares the same 100-pin LQFP (PZ) package and pinout with MSP430FR6879IPZR and MSP430FR6877IPZR. Signal assignments, power domains, and peripheral mappings are identical across these variants, enabling drop-in replacement where FRAM size and timer configuration meet design requirements.
