Product details
Overview
MSP430FR6988IPZ from Texas Instruments is a 16-bit ultra-low-power FRAM microcontroller in 100-pin LQFP (14 mm × 14 mm), featuring 96 KB FRAM, 2 KB RAM, 12-bit ADC with 16 external inputs, integrated LCD driver (up to 320 segments), 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 mode at 0.35 µA in LPM3.5.
For engineers reviewing the MSP430FR6988IPZ datasheet, MSP430FR6988IPZ pinout, MSP430FR6988IPZ application, or MSP430FR6988IPZ equivalent, key selection criteria include ESI peripheral support for capacitive sensing in utility meters, FRAM endurance (1015 write cycles), low-power RTC operation, and UART/I²C bootloader compatibility - all validated for water/heat metering and portable data loggers.
Technical Context
The MSP430FR6988IPZ implements the MSP430 CPUXV2 core with 16 general-purpose registers and executes instructions at up to 16 MHz using DCO, HFXT, or LFXT clock sources. Its power architecture delivers seven low-power modes, including LPM3.5 (RTC active, 0.35 µA) and LPM4.5 (shutdown, 0.02 µA), optimized for battery-powered metering systems requiring decades of operation on coin cells.
Peripherals are tightly coupled to low-power operation: the ESI module performs background analog measurements without CPU intervention; the 3-channel DMA enables autonomous data movement between ADC, FRAM, and LCD; and the AES256 coprocessor provides hardware-accelerated encryption for secure firmware updates and data logging.
