MSP430FR2476 MCU
The MSP430FR2476 is an ultra-low-power MSP430FRx FRAM-based microcontroller (MCU), which offer
extended data logging and security capabilities. The MSP430FR2476 offers the small LQFP package
(7 mm × 7 mm) in the FRAM microcontroller portfolio, combined with a variety of integrated peripherals
and ultra-low power consumption. FRAM is a cutting edge memory technology, combining the best
features of flash and RAM into one nonvolatile memory. For more information on FRAM, visit
Device features include:
•
1.8-V to 3.6-V operation
•
16-bit RISC architecture up to 16-MHz system clock and 8-MHz FRAM access
•
64KB of program FRAM, 512 bytes of information FRAM, and 8KB of RAM
•
12-channel 12-bit ADC
•
One enhanced comparator with integrated 6-bit DAC as reference voltage
•
Four 16-bit timers with three capture/compare registers (Timer_B3)
•
One 16-bit timer with seven capture/compare registers (Timer_B7)
•
One 16-bit counter-only RTC
•
16-bit cyclic redundancy check (CRC)
•
43 GPIOs
