C505CA4EMCAKXQMA1

Overview

The C505CA4EMCAKXQMA1 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, eight analog inputs with 10-bit A/D resolution, and 34 digital I/O lines. The unit utilizes a P-MQFP-44 package.

Feature Summary

• Superset of standard 8051 architecture with eight 16-bit datapointers
• Integrated full CAN controller compliant with version 2.0 B
• On-chip 10-bit A/D converter with eight analog input channels
• Enhanced Hooks emulation support for debugging

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 type. Confirm that the component matches the required functional specification, particularly regarding the presence of the CAN controller and OTP memory size. Ensure compatibility with existing system voltage and interface requirements before procurement.

Selection Notes

Select this variant for applications requiring robust automotive communication protocols via the integrated CAN module. The 10-bit ADC resolution supports precise analog signal processing. Consider the 32 KB OTP capacity for production environments where code flexibility is needed without external memory constraints.

Part Context

This component belongs to the C500 series of 8-bit single-chip microcontrollers. It extends the capabilities of the base C505 model by adding a full CAN controller and increasing the XRAM size to 1 KB. The CA designation indicates the inclusion of the CAN peripheral and 10-bit ADC resolution.

Replacement Considerations

C505CA-4R variants offer identical functionality but utilize Mask ROM instead of OTP.
