128 KB FRAM MCU with integrated LCD driver – design-in memo
It packs 128 KB of FRAM program memory and 2 K x 8 of RAM, with 63 general-purpose I/O lines. The standout feature is the integrated LCD controller, which drives segment displays directly – a common requirement in metering, medical instrumentation, and industrial panel applications.
FRAM instead of Flash – what it changes
The 128 KB program memory is FRAM, not Flash. That means writes are fast (microsecond range), low-energy, and endure far more cycles – typically 10^15 vs 10^4-10^5 for Flash. The trade-off: FRAM density tops out lower than Flash in this generation, so 128 KB is the ceiling here. If your code image fits, you gain write endurance and simplified BOM.
Lifecycle reality – obsolete, sourced to order
Despite the spec table showing a 'current' lifecycle stage, the official product status from TI is Obsolete. That means TI has stopped manufacturing this exact order code. No last-time-buy window remains open. For production or repair, this part is available only through independent distribution – we source it from spot-market inventory, with date codes and quantities confirmed at quote time. Buyers should plan for a one-time procurement or qualify a direct replacement for ongoing builds.
Package and footprint – 80-LQFP 12x12 mm
The device comes in an 80-lead LQFP with a 12x12 mm body. Surface-mount only.
