4.1 ARM Cortex-M3 CPU
The CY8C53 family of devices has an ARM Cortex-M3 CPU core. The Cortex-M3 is a low power 32-bit three-stage pipelined Harvard
architecture CPU that delivers 1.25 DMIPS/MHz. It is intended for deeply embedded applications that require fast interrupt handling
features.
The Cortex-M3 CPU subsystem includes these features:
