Product details
Overview
MSP430FR5888IPM from Texas Instruments is a 16-bit ultra-low-power FRAM microcontroller in 64-pin LQFP package, featuring 96KB FRAM, 2KB RAM, 12-bit ADC with 12 external inputs, RTC with calendar, and Extended Scan Interface (ESI) for precision metering. It operates from 1.8 V to 3.6 V and targets battery-powered utility meters.
For engineers reviewing the MSP430FR5888IPM datasheet, MSP430FR5888IPM pinout, MSP430FR5888IPM application, or MSP430FR5888IPM equivalent, key selection criteria include ESI peripheral support, FRAM endurance (10¹⁵ write cycles), LPM3.5 RTC current (0.35 µA), 64-pin LQFP footprint, and UART/I²C dual-BSL capability.
Technical Context
The MSP430FR5888IPM integrates a 16-bit CPUXV2 core with up to 16-MHz DCO clock, three 16-bit Timer_A modules (3/3/5 capture/compare registers), one 16-bit Timer_B (7 registers), and dual eUSCI_A/eUSCI_B peripherals supporting UART, IrDA, SPI, and I²C. Its ESI peripheral enables background capacitive sensing for fluid/gas volume measurement without CPU intervention.
Power management includes seven low-power modes: Active (~100 µA/MHz), LPM3 (0.4 µA), LPM3.5 (RTC active, 0.35 µA), and LPM4.5 (shutdown, 0.02 µA). The FRAM memory architecture unifies program, data, and storage space with 125 ns word writes and radiation resistance.

FAQ
What is the maximum operating frequency of the MSP430FR5888IPM?
The MSP430FR5888IPM supports a maximum system clock frequency of 16 MHz using its factory-trimmed DCO oscillator. This frequency is achievable across the full 1.8 V to 3.6 V supply range and enables high-speed FRAM writes (125 ns per word) and real-time signal processing in metering applications without compromising ultra-low-power operation in standby modes.
Does the MSP430FR5888IPM support hardware encryption?
No, the MSP430FR5888IPM does not include a hardware AES module. Unlike some higher-tier MSP430FR6xx devices, this variant omits the AES accelerator block. Security relies on software-based cryptographic libraries executed on the 16-bit CPUXV2 core, with FRAM providing tamper-resistant nonvolatile storage for keys and logs.
How many external ADC input channels does the MSP430FR5888IPM support?
The MSP430FR5888IPM supports 12 external input channels on its ADC12_B module. These channels are accessible via dedicated analog pins (A0–A15) with multiplexing, and the device datasheet confirms "12 ext" under ADC12_B in the Device Comparison table-matching the MSP430FR588x family specification and excluding internal references or temperature sensor inputs.
What is the purpose of the ESI peripheral in the MSP430FR5888IPM?
The Extended Scan Interface (ESI) in the MSP430FR5888IPM is a dedicated hardware peripheral for high-precision capacitive sensing used in water, heat, and gas metering. It performs background charge-transfer measurements on up to eight channels (ESICH0–ESICH3 and ESICI0–ESICI3) without CPU intervention, enabling ultra-low-power, noise-immune fluid volume calculation essential for OIML-certified utility meters.
Can the MSP430FR5888IPM drive an LCD display directly?
Yes, the MSP430FR5888IPM integrates an LCD_C module capable of driving up to 48 segments in static or multiplexed configurations. It provides internal voltage generation (via R13/R23/R33 pins), programmable contrast control, and direct segment/COM pin mapping-eliminating external bias circuitry and reducing BOM count in meter displays.
