Frequently asked questions
What is the replacement for LPC2105BBD48?
NXP's official pin-compatible replacement is the LPC2105FBD48, which uses the same ARM7 die and 48-LQFP footprint. However, that variant is also end-of-life. For new designs, migrate to a current NXP ARM7 or Cortex-M3 MCU in a similar 48-QFP package.
What is the difference between LPC2105 and LPC2106?
The LPC2106 doubles both Flash to 256 KB and RAM to 64 KB while maintaining the same 48-LQFP pinout and 60 MHz core speed. It is a drop-in hardware replacement if your firmware fits the larger memory.
What is LPC2105BBD48's pinout?
The LPC2105BBD48 uses a 48-LQFP package (7x7 mm) with 32 general-purpose I/O pins. The pinout is identical across the LPC2105 and LPC2106 in the same package — consult the LPC2105 datasheet for the full pin assignment table.
