LPC1111/12/13/14

32-bit ARM Cortex-M0 microcontroller

Functional description

7.1 ARM Cortex-M0 processor

The ARM Cortex-M0 is a general purpose, 32-bit microprocessor, which offers high

performance and very low power consumption.

7.2 On-chip flash program memory

The LPC1111/12/13/14 contain 32 kB (LPC1114), 24 kB (LPC1113), 16 kB (LPC1112), or

8 kB (LPC1111) of on-chip flash memory.

7.3 On-chip SRAM

The LPC1111/12/13/14 contain a total of 8 kB, 4 kB, or 2 kB on-chip static RAM memory.

7.4 Memory map

The LPC1111/12/13/14 incorporates several distinct memory regions, shown in the

following figures. Figure 5 shows the overall map of the entire address space from the

user program viewpoint following reset. The interrupt vector area supports address

remapping.

The AHB peripheral area is 2 megabyte 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 kilobytes of space. This allows

simplifying the address decoding for each peripheral.
