FRAM memory — what it means for firmware and field updates
The 64 KB program space is ample for moderate control loops and communications stacks; the 2 KB RAM handles stack and temporary variables. For designs that previously needed external EEPROM, this part absorbs that function on-chip.
Package and mounting — 38-pin TSSOP
Housed in a 38-TSSOP (0.240", 6.10 mm width), this is a surface-mount part with 0.65 mm pitch. The narrow body saves board area but calls for a decent soldering profile — rework with a hot-air station is doable, but the fine pitch means double-checking alignment before reflow.
No stock or lead-time numbers here, but the part is in the active channel.
