Product details
Overview
MSP430FR6889IPZR from Texas Instruments is a 16-bit ultra-low-power mixed-signal microcontroller featuring 128KB ferroelectric RAM (FRAM), 2KB SRAM, integrated 12-bit ADC with 16 external inputs, LCD driver supporting up to 320 segments, and dual eUSCI modules (UART/IrDA/SPI + I²C/SPI). It operates from 1.8 V to 3.6 V and targets battery-powered metering applications requiring nonvolatile data logging and real-time clock functionality.
For engineers reviewing the MSP430FR6889IPZR datasheet, MSP430FR6889IPZR pinout, MSP430FR6889IPZR application, or MSP430FR6889IPZR equivalent, key selection criteria include FRAM endurance (10¹⁵ write cycles), LPM3.5 RTC current (0.35 µA typical), 100-pin LQFP package compatibility, and support for capacitive touch I/O without external components.
Technical Context
The MSP430FR6889IPZR implements the CPUXV2 16-bit RISC core with hardware multiplier and three-channel DMA, enabling deterministic real-time processing in ultra-low-power modes. Its clock system integrates DCO (10 factory-trimmed frequencies), LFXT (32-kHz crystal), and HFXT (high-frequency crystal) sources, with automatic clock gating per peripheral domain.
Peripherals are organized into low-power domains: RTC_C and LCD_C operate in LPM3.5, while ADC12_B, eUSCI_A/B, and Timer_B are independently configurable for wake-on-event operation. The device supports hardware UART and I²C bootloaders (BSL), with dedicated pins for Spy-Bi-Wire debugging and JTAG test access.

FAQ
What is the maximum operating frequency of the MSP430FR6889IPZR?
The MSP430FR6889IPZR supports a maximum system clock frequency of 16 MHz using the integrated DCO or external HFXT crystal. This allows execution of complex metrology algorithms within tight timing windows while maintaining sub-100 µA/MHz active current efficiency. The device achieves this performance across the full 1.8 V–3.6 V supply range, with frequency stability maintained via SVS monitoring.
Does the MSP430FR6889IPZR support hardware-accelerated cryptography?
No, the MSP430FR6889IPZR does not include an AES accelerator. It lacks the AES-128 module present in the MSP430FR69xx family. For applications requiring hardware encryption (e.g., DLMS/COSEM-compliant metering), the MSP430FR6989IPZ is the functionally aligned alternative with identical FRAM, I/O, and LCD capabilities plus integrated AES-128.
How many LCD segments can the MSP430FR6889IPZR drive?
The MSP430FR6889IPZR drives up to 320 segments via its integrated LCD_C peripheral, supporting static, 2-, 3-, 4-, 6-, and 8-mux configurations. This capability enables direct connection to large-format segment LCDs used in utility meters without external bias generation or multiplexing ICs, reducing bill-of-materials cost and board area.
What debug interface does the MSP430FR6889IPZR use?
The MSP430FR6889IPZR uses the Spy-Bi-Wire (SBW) interface via TEST/SBWTCK and RST/NMI/SBWTDIO pins for programming and debugging. This two-wire protocol occupies minimal PCB space compared to full JTAG and is supported by TI's MSP-FET and EnergyTrace++ tools for real-time power profiling and firmware development.
Is the MSP430FR6889IPZR pin-compatible with other devices in the FR68xx family?
Yes, the MSP430FR6889IPZR in the 100-pin LQFP (PZ) package shares identical pinout and electrical characteristics with the MSP430FR6879IPZR and MSP430FR6989IPZ. This enables drop-in replacement across variants where FRAM size, peripheral set, or security features align with design requirements-verified by TI's official device comparison tables.
