Product data sheet
7.1 On-chip flash programming memory
7.2 SRAM
7.3 On-chip ROM
7.4 Memory map
The LPC11U1x contain up to 32 kB on-chip flash program memory. The flash can be
programmed using In-System Programming (ISP) or In-Application Programming (IAP)
via the on-chip boot loader software.
The LPC11U1x contain a total of 6 kB on-chip static RAM memory.
The on-chip ROM contains the boot loader and the following Application Programming
Interfaces (APIs):
The LPC11U1x incorporates several distinct memory regions, shown in the following
figures.
program viewpoint following reset. The interrupt vector area supports address remapping.
The AHB peripheral area is 2 MB in size and is divided to allow for up to 128 peripherals.
The APB peripheral area is 512 kB in size and is divided to allow for up to 32 peripherals.
Each peripheral of either type is allocated 16 kB of space. This allows simplifying the
address decoding for each peripheral.
