C505CA4EMCAFXUMA1

Overview

The C505CA4EMCAFXUMA1 is an 8-bit microcontroller from the Infineon C500 family, based on a superset of the standard 8051 architecture. It features 32 Kbyte of One-Time Programmable (OTP) memory and 1 Kbyte of internal XRAM. The device operates at frequencies up to 20 MHz with instruction cycle times as low as 300 ns. It integrates a full CAN controller compliant with version 2.0 B, an 8-channel 10-bit A/D converter, three 16-bit timers/counters, and a full-duplex USART. The unit includes eight 16-bit datapointers and supports Enhanced Hooks emulation technology.

Feature Summary

• Integrates a full CAN controller compliant with version 2.0 B for high-speed communication
• Includes an 8-channel 10-bit analog-to-digital converter with sample-and-hold multiplexer
• Features eight 16-bit datapointers for efficient external data memory addressing
• Supports Enhanced Hooks Emulation Technology for in-circuit debugging

Applications

• Automotive body electronics
• Industrial control systems
• Distributed sensor networks

Procurement Notes

Verify the specific ordering suffix against official Infineon documentation to confirm package type, temperature range, and delivery format. Confirm that the OTP memory variant matches the intended production requirements, as this memory type cannot be reprogrammed after fabrication. Ensure compatibility with existing design infrastructure regarding pinout and voltage levels.

Selection Notes

Select this component when a robust 8-bit solution with integrated CAN bus capability is required. The C505CA derivative specifically provides the necessary 10-bit ADC resolution and 1 Kbyte XRAM for applications exceeding standard 8051 capabilities. Consider the 44-pin P-MQFP package constraints and the availability of development tools supporting the Enhanced Hooks interface.

Part Context

This part belongs to the C500 family of 8-bit single-chip microcontrollers manufactured by Infineon Technologies. The C505CA variant is designed as a superset of the 8051 architecture, enhancing performance through additional datapointers and peripherals. It serves as a bridge between basic 8051 controllers and more complex architectures, focusing on automotive and industrial environments requiring reliable CAN communication.

Replacement Considerations

Direct replacements within the same family include other C505CA derivatives with different memory types or packages, such as C505CA-4R. Cross-family migration may require significant architectural changes due to differences in instruction sets and peripheral configurations.
