64 KB FRAM — the non-volatile memory that writes like RAM
Its program memory is 64 KB of FRAM — a non-volatile memory that combines the fast write speed and low power of RAM with the data retention of Flash, and it eliminates the erase-before-write cycle.
Peripherals and I/O — 83 pins and a 12-bit ADC
With 83 general-purpose I/Os and a 16-channel 12-bit ADC, this MCU can handle a sensor-rich board without external muxes or GPIO expanders.
Package and footprint — 100-LQFP, 14x14 mm
The fine-pitch leads (0.5 mm typical for LQFP-100) need careful solder-paste stencil design and a clean reflow oven profile. Store the reels dry — MSL 3 out of the bag means a bake before reflow if the moisture-barrier bag has been open past the floor-life window.
