Product details
Overview
MSP430FR5989IPM from Texas Instruments is a 16-bit ultra-low-power FRAM microcontroller in 64-pin LQFP package, featuring 128KB nonvolatile FRAM, 2KB RAM, 12-bit ADC with 12 external inputs, RTC with calendar, and integrated ESI for metering applications. It operates from 1.8 V to 3.6 V and delivers 100 µA/MHz active current, targeting battery-powered utility meters and portable data loggers.
For engineers reviewing the MSP430FR5989IPM datasheet, MSP430FR5989IPM pinout, MSP430FR5989IPM application, or MSP430FR5989IPM equivalent, key selection criteria include FRAM endurance (1015 writes), LPM3.5 RTC current (0.35 µA), ESI peripheral support, AES256 security coprocessor, and 64-pin LQFP mechanical compatibility with legacy MSP430FR59xx designs.
Technical Context
The MSP430FR5989IPM implements the MSP430 CPUXV2 core with 16 general-purpose registers and executes instructions at up to 16 MHz. Its clock system integrates DCO with factory-trimmed frequencies, LFXT (32 kHz crystal), and HFXT (up to 24 MHz) for flexible timing across low-power and performance modes.
Peripherals include three eUSCI modules (eUSCI_A0/A1 for UART/IrDA/SPI; eUSCI_B0/B1 for I²C/SPI), five 16-bit timers (TA0–TA3, TB0), CRC16/CRC32 hardware accelerators, and an Extended Scan Interface (ESI) optimized for capacitive sensing in water/heat metering without external components.

FAQ
What is the maximum operating frequency of the MSP430FR5989IPM?
The MSP430FR5989IPM supports a maximum CPU clock frequency of 16 MHz, achieved via its digitally controlled oscillator (DCO) with 10 factory-trimmed frequencies or external HFXT crystal up to 24 MHz. This allows real-time signal processing in metering applications while maintaining sub-100-µA/MHz active current efficiency.
Does the MSP430FR5989IPM include an integrated LCD driver?
No, the MSP430FR5989IPM does not include functional LCD_C peripheral support. Per Table 3-1 in the datasheet, LCD_C is marked "N/A" for all MSP430FR598x variants, unlike the MSP430FR698x series which supports up to 320 segments. The MSP430FR5989IPM pinout reserves LCD-related pins (e.g., P6.x, P2.x) but they are disabled in silicon.
How many capture/compare registers does the MSP430FR5989IPM support across its timers?
The MSP430FR5989IPM includes five 16-bit timers: TA0 and TA1 each have 3 capture/compare registers; TA2 has 2; TA3 has 5; TB0 has 7. This totals 20 configurable CCRs, enabling simultaneous PWM generation, input capture for flow pulses, and RTC-synchronized event timing in utility meter firmware.
What bootloading interfaces are supported by the MSP430FR5989IPM?
The MSP430FR5989IPM supports both UART-based and I²C-based hardware bootloader (BSL). UART BSL uses P2.0 (BSLTX) and P2.1 (BSLRX); I²C BSL uses P1.6 (BSLSDA) and P1.7 (BSLSCL). Selection is determined at manufacturing - the part number suffix does not indicate BSL type, so firmware must be validated for both modes.
Is the Extended Scan Interface (ESI) available on all pins of the MSP430FR5989IPM?
No, ESI functionality is limited to P9.0–P9.7 (ESICH0–ESICH3 and ESICI0–ESICI3) and PJ.x pins designated for ESI clocking. Other GPIOs (e.g., P1.x–P8.x) support capacitive touch via CTSense but lack the dedicated ESI analog front-end for high-precision, low-noise electrode scanning required in water/heat metering.
