Packaging

Type 100 pin LQFP body size 14 x 14 mm thickness about 1.4 mm typical lead pitch 0.5 mm typical

Material epoxy molding compound with copper leadframe and lead free tin finish

Mounting surface mount compatible with standard reflow profiles

Pin configuration 100 pins with groups for power VCC and GND analog inputs ADC channels serial interfaces I2C SPI UART USART LCD segment and common lines timer PWM outputs and general purpose I O

Thermal characteristics typical of LQFP 100 packages with good heat dissipation through leads and PCB copper planes use generous ground planes for lower thermal resistance

Electrical properties supply 1.8 V to 3.6 V core up to 16 MHz internal oscillator 12 bit ADC 16 channels FRAM 128 KB RAM 2 KB 63 I O pins multiple low power modes and integrated LCD driver

Shipping package tray orientation consistent with automated pick and place

Compliance RoHS3 and lead free

Lifecycle

Status active and widely used in current MSP430 FRAM designs not near discontinuation based on publicly available industry information

TI pin family and memory variants can serve as drop in or near drop in alternatives depending on pinout and LCD needs

- MSP430FR6979IPZ 100 LQFP same FRAM 128 KB same package and feature class check exact pinout and LCD mapping

- MSP430FR6989IPZ 100 LQFP FRAM 256 KB extended features LCD driver similar pinout check memory and peripheral differences

- MSP430FR6889IPZ 100 LQFP FRAM 128 KB similar low power and LCD support verify pin mapping

- MSP430FR5969 and MSP430FR5959 smaller pin counts FRAM based alternatives if fewer I O pins are acceptable

- MSP430F5438A flash based alternative if FRAM is not required larger RAM and rich peripherals different memory technology

Cross vendor functional alternatives if FRAM is not mandatory

- Renesas RL78 G13 series LQFP 100 low power flash up to 128 KB with ADC and serial interfaces

- Microchip PIC24FJ128GA3xx series LQFP 100 low power flash 128 KB with 12 bit ADC and serial interfaces

- NXP LPC11xx and LPC15xx families 32 bit ARM Cortex M low power with comparable peripherals different architecture
