Product details
Overview
MSP430FR5889IPM from Texas Instruments is a 16-bit ultra-low-power FRAM microcontroller with 128KB nonvolatile memory, 2KB RAM, and integrated extended scan interface (ESI) for precision analog sensing. It operates from 1.8 V to 3.6 V, delivers 100 µA/MHz active current, and supports real-time clock (RTC) operation at 0.35 µA in LPM3.5-enabling battery-powered water/heat metering systems with >10-year runtime.
For engineers reviewing the MSP430FR5889IPM datasheet, MSP430FR5889IPM pinout, MSP430FR5889IPM application, or MSP430FR5889IPM equivalent, key selection criteria include ESI peripheral support for capacitive fluid/gas measurement, FRAM endurance (1015 write cycles), 12-bit ADC with 16 external channels, and LQFP-64 package compatibility with industrial metering PCB layouts.
Technical Context
The MSP430FR5889IPM 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, LFXT (32 kHz crystal), and HFXT (up to 24 MHz) with automatic calibration.
Peripherals include dual eUSCI_A (UART/IrDA/SPI) and 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 7 capture/compare registers per timer-optimized for time-critical metrology tasks.

FAQ
What is the maximum operating frequency of the MSP430FR5889IPM?
The MSP430FR5889IPM supports a maximum system clock frequency of 16 MHz using its factory-trimmed DCO or external HFXT crystal. This allows deterministic real-time execution of metrology algorithms while maintaining ultra-low-power efficiency-verified across the full 1.8 V to 3.6 V supply range specified in the SLASE32C datasheet.
Does the MSP430FR5889IPM support hardware encryption?
No, the MSP430FR5889IPM does not include a hardware AES engine. It relies on software-based cryptographic libraries for security functions. For applications requiring hardware-accelerated encryption, consider the MSP430FR5969IPM, which integrates AES-128. The MSP430FR5889IPM prioritizes ESI and FRAM performance over cryptographic acceleration.
How many external ADC input channels does the MSP430FR5889IPM support?
The MSP430FR5889IPM supports up to 12 external analog input channels via its ADC12_B module, as confirmed in Table 3-1 of the SLASE32C datasheet. Unlike the MSP430FR6889IPN variant, it does not support the full 16-channel configuration-making it optimized for simpler single-sensor or dual-sensor metrology designs.
What is the purpose of the ESI peripheral in the MSP430FR5889IPM?
The Extended Scan Interface (ESI) in the MSP430FR5889IPM is a dedicated hardware peripheral for high-precision, low-power capacitance measurement-used in water/heat meters to detect fluid level, flow, or gas concentration without CPU involvement. It supports up to four differential input channels (ESICH0–ESICH3) and operates autonomously in low-power modes.
Is the MSP430FR5889IPM pin-compatible with other devices in the MSP430FR588x family?
Yes, the MSP430FR5889IPM shares identical pinout and electrical characteristics with the MSP430FR5888IPM and MSP430FR5887IPM within the same LQFP-64 package. This allows direct substitution in existing designs when migrating between FRAM sizes (128KB/96KB/64KB) without PCB changes-subject to verifying software compatibility with memory map differences.
