Introduction

The C505CA-xC derivatives, which refer to C505CA-4RC and C505CA-LC in this document, are high performance derivatives of the Infineon C500 family of 8-bit microcontrollers. The C505CA-xC derivatives are fully compatible to the standard 8051 microcontroller. Additionally the C505CA-xC provides extended power save provisions, on-chip RAM, 1K byte XRAM, on-chip ROM, 10-bit A/D converter, and RFI related improvements.
