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.
7.1.1 System tick timer
The ARM Cortex-M0 includes a System Tick timer (SYSTICK) that is intended to generate
a dedicated SYSTICK exception at a 10 ms interval.
7.2 On-chip flash program memory
The LPC122x contain up to 128 kB of on-chip flash memory.
7.3 On-chip SRAM
The LPC122x contain a total of up to 8 kB on-chip static RAM memory.
7.4 Memory map
The LPC122x incorporates several distinct memory regions, shown in the following
figures. Figure 4 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.
