C505CA4EMCAFXQMA1

Overview

The C505CA4EMCAFXQMA1 is an 8-bit microcontroller from the Infineon C500 family, based on the 8051 architecture. It features a 32 KB OTP program memory and 1 KB of XRAM. The device operates at frequencies up to 20 MHz with a 300 ns instruction cycle time. It includes a full CAN controller compliant with version 2.0 B, an 8-channel 10-bit A/D converter, and three 16-bit timers. The unit provides 34 digital I/O lines and utilizes a P-MQFP-44 package.

Feature Summary

• Integrates a full CAN controller compliant with version 2.0 B for high-speed communication
• Includes eight analog input channels with 10-bit resolution via an on-chip A/D converter
• Features Enhanced Hooks Technology for comprehensive on-chip emulation support
• Provides eight 16-bit datapointers to enhance external data memory addressing

Applications

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

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm temperature range and delivery format. Confirm that the component meets RoHS compliance standards required for the target assembly process. Ensure compatibility with existing design tools and programming interfaces before finalizing procurement plans.

Selection Notes

Select this variant for applications requiring robust automotive-grade communication protocols alongside standard 8051 processing capabilities. The inclusion of a full CAN module distinguishes it from non-CAN derivatives within the C505 series. Consider the 10-bit ADC resolution when designing signal acquisition circuits compared to 8-bit alternatives.

Part Context

This component belongs to the C505/C505C/C505A/C505CA series of 8-bit single-chip microcontrollers. It serves as a superset of the standard 8051 architecture, offering enhanced peripheral integration. The C505CA specifically combines the CAN controller found in the C505C with the higher performance specifications of the C505A.

Replacement Considerations

Direct substitutes include other variants within the C505 family such as the C505CA-4R or C505C-4E, provided pinout and feature requirements align. Verify functional equivalence regarding the presence of the CAN controller and memory type before substitution.
