128 KB FRAM at 16 MHz — the so-what for the BOM
FRAM writes at bus speed with no erase cycle, so firmware updates and data logging don't stall the core the way Flash-based parts do. The 16 MHz clock, 2K x 8 RAM, and 83 I/O lines in a 100-LQFP package target metering, building automation, and handheld instruments where non-volatile storage must survive frequent writes and the power budget sits below 1 mA/MHz.
Package and footprint
Housed in a 100-LQFP (14x14 mm) with 0.5 mm pitch. Surface-mount only. The 83 I/O pins give routing flexibility for parallel LCD buses or large key matrices, but the fine pitch demands a controlled reflow profile and good solder-paste registration.
