Product details
Overview
MSP430FR6989IPZR from Texas Instruments is a 16-bit ultra-low-power mixed-signal microcontroller featuring 128KB ferroelectric RAM (FRAM), 2KB SRAM, integrated LCD driver (up to 320 segments), 12-bit ADC with 16 external inputs, and Extended Scan Interface (ESI) for metering applications. It operates from 1.8 V to 3.6 V and supports real-time clock (RTC) with calendar and alarm functions.
For engineers reviewing the MSP430FR6989IPZR datasheet, MSP430FR6989IPZR pinout, MSP430FR6989IPZR application, or MSP430FR6989IPZR equivalent, key selection considerations include FRAM endurance (10¹⁵ write cycles), ESI-based background sensing for water/heat meters, LPM3.5 RTC current (0.35 µA), 100-pin LQFP package compatibility, and AES256 security coprocessor integration.
Technical Context
The MSP430FR6989IPZR implements the ULP CPUXV2 core with seven low-power modes, including LPM3.5 (RTC active) and LPM4.5 (shutdown at 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 battery-operated metering systems.
Peripherals include dual eUSCI_A (UART/IrDA/SPI) and dual eUSCI_B (I²C/SPI) modules, three-channel DMA, 32-bit hardware multiplier, CRC16/CRC32 engines, and five 16-bit timers (TA0–TA3, TB0) with up to seven capture/compare registers each - all optimized for deterministic, low-energy signal processing in utility measurement.
Key Specifications

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 |
|---|---|---|---|
| MSP430FR6989IPN | 80-pin LQFP (12 mm × 12 mm); same FRAM/SRAM/peripherals but 17 fewer I/O pins and no LCD_COM7 or ESIC2OUT. | Suitable for space-constrained designs where 320-segment LCD or dual ESI output channels are unnecessary. | Select IPN when board area is critical and full 100-pin I/O count or maximum LCD drive capability is not required. |
| MSP430FR5989IPM | 64-pin LQFP (10 mm × 10 mm); lacks LCD_C module and ESI peripheral; retains FRAM, ADC12_B, and AES256. | Targeted at non-display, non-capacitive-sensing applications such as smart sensors or secure edge nodes without human interface. | Choose IPM when LCD and ESI are excluded, and smaller footprint with identical security/analog capabilities is preferred. |

Does the MSP430FR6989IPZR support hardware encryption?
Yes, the MSP430FR6989IPZR integrates a dedicated AES256 security coprocessor with true random number generation seed. This enables hardware-accelerated encryption and decryption of firmware images and sensitive meter data - a requirement for compliance with utility cybersecurity standards like DLMS/COSEM and EN 13757-4.
How many external analog inputs does the ADC support on the MSP430FR6989IPZR?
The MSP430FR6989IPZR features the ADC12_B module supporting up to 16 external analog input channels, plus 8 differential input configurations. Inputs are accessible via P1.0–P1.7, P4.0–P4.7, and P5.4–P5.7, enabling simultaneous connection of multiple sensors such as RTDs, thermistors, and pressure transducers in metering applications.
What LCD configuration options does the MSP430FR6989IPZR provide?
The MSP430FR6989IPZR integrates the LCD_C peripheral supporting static, 2-, 3-, 4-, 6-, and 8-mux configurations with up to 320 segments. It drives common outputs (COM0–COM7) and segment lines directly, eliminating need for external bias generators or display controllers - ideal for battery-powered utility displays with long readability lifetime.
Is the MSP430FR6989IPZR pin-compatible with other devices in the FR69xx family?
Yes, the MSP430FR6989IPZR in the 100-pin LQFP (PZ) package shares identical pinout with MSP430FR6988IPZR and MSP430FR6987IPZR. This allows hardware reuse across variants differing only in FRAM size (128KB/96KB/64KB) while preserving layout, routing, and firmware compatibility.
