Frequently asked questions
What is the closest pin-compatible alternative to LPC2146FBD64,151?
No official pin-compatible second source or successor is listed in the lifecycle record. The LPC2100 series has multiple density variants (e.g., LPC2138 with 512 KB Flash), but pin compatibility across the family varies by peripheral set. A pin-to-pin replacement would require reviewing the specific LPC2146 footprint against current NXP ARM7 or Cortex-M3 offerings in 64-LQFP.
What is LPC2146FBD64,151's listed speed?
The core processor runs at 60 MHz, which is the maximum clock frequency for the ARM7TDMI-S core in this device.
What series is LPC2146FBD64,151 from?
It belongs to the NXP LPC2100 series of ARM7-based microcontrollers.
