1.5 Architectural overview

The LPC2101/02/03 consist of an ARM7TDMI-S CPU with emulation support, the ARM7
Local Bus for interface to on-chip memory controllers, the AMBA Advanced
High-performance Bus (AHB) for interface to the interrupt controller, and the ARM
Peripheral Bus (APB, a compatible superset of ARM's AMBA Advanced Peripheral Bus)
for connection to on-chip peripheral functions. The LPC2101/02/03 configures the
ARM7TDMI-S processor in little-endian byte order.
AHB peripherals are allocated a 2 megabyte range of addresses at the very top of the
4 gigabyte ARM memory space. Each AHB peripheral is allocated a 16 kB address space
within the AHB address space. LPC2101/02/03 peripheral functions (other than the
interrupt controller) are connected to the APB bus. The AHB to APB bridge interfaces the
APB bus to the AHB bus. APB peripherals are also allocated a 2 megabyte range of
addresses, beginning at the 3.5 gigabyte address point. Each APB peripheral is allocated
a 16 kB address space within the APB address space.
