Features & Applications


The LPC2103FBD48,151 is a single-chip 16-bit/32-bit microcontroller with real-time emulation that combines the microcontroller with 32 kB of embedded high-speed flash memory.

The 128-bit wide memory interface and a unique accelerator architecture enable 32-bit code execution at the maximum clock rate.

Key Features:

  • 16-bit/32-bit ARM7TDMI-S microcontroller in tiny LQFP48 and HVQFN48 packages.
  • 2 kB/4 kB/8 kB of on-chip static RAM
  • 8 kB/16 kB/32 kB of on-chip flash program memory. 
  • 128-  bit  wide interface/accelerator enables high-speed 70 MHz operation.
  • ISP/IAP via on-chip bootloader software.
  • EmbeddedICE-RT offers real-time debugging with the on-chip RealMonitor software.
