The 2 KB of SRAM handles stack and scratchpad data. This is the part for designs that want unified memory and field-update capability without wearing out Flash sectors. ## Peripheral set for metering and display applications On-chip peripherals include a brown-out reset, DMA controller, LCD driver, POR, PWM, and watchdog timer. The 8-channel 12-bit ADC handles analog inputs without an external converter. With 46 general-purpose I/O lines in the 56-TSSOP package, you have room for a keypad, segment LCD, and a few external sensors. ## Lifecycle and sourcing The base product number MSP430FR68221 covers the family; the I suffix indicates the industrial temperature grade, G the 56-TSSOP package, and R the tape-and-reel shipping medium.","metaTitle":"Texas Instruments MSP430FR68221IG56R 16-bit MCU, 64KB FRAM","metaDescription":"TI MSP430FR68221IG56R 16-bit MCU with 64KB FRAM, 16MHz CPUXV2 core, 46 I/O, LCD driver, industrial temp -40°C to 85°C.
