Frequently asked questions
The peer LPC1112FDH20/102:5 has 18 I/O versus 22 on the LPC1114FDH28/102:5 — can the same 32KB flash and 4KB RAM firmware be ported without recompile?
The flash and RAM sizes are identical, and the ARM Cortex-M0 core and CMSIS peripheral map are broadly compatible within the LPC1100 family. However, the four-GPIO shortfall means any firmware binary that maps signals to those specific pins will not reproduce those functions on the LPC1112 without a recompile and pin reassignment. If the firmware is pin-agnostic or those four extra pins are unused, a re-flash of the same compiled image may work — but confirm the:5 stepping alignment in the build configuration before committing.
We need 50 units for a Q4 panel build and have had EOL PCNs on prior LPC1100 tape reels — what is the sourcing posture on this part?
Active status supports a 50-unit BOM commitment without an immediate supply cliff. The Cut Tape (CT) and Tape & Reel (TR) packaging options are both listed, which allows flexibility for prototype versus production ordering. Lead time and minimum order quantity should be confirmed against current stock availability through your distributor desk — open-market purchases of LPC1100 series TSSOP parts carry a documented risk of pulls or remarked parts, and the current MCU sourcing environment has elevated allocation sensitivity on older NXP TSSOP reels.
