C505CA4EMCABXUMA1

Overview

The C505CA4EMCABXUMA1 is an 8-bit microcontroller from the Infineon C500 family, based on a superset of the standard 8051 architecture. It features up to 20 MHz operating frequency with instruction cycle times of 375 ns at 16 MHz and 300 ns at 20 MHz. The device includes 32 Kbyte of one-time programmable (OTP) memory, 256 bytes of internal RAM, and 1 Kbyte of XRAM. 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 provides 32 plus 2 digital I/O lines and operates within a temperature range of -40°C to +125°C.

Feature Summary

• Superset of the 8051 architecture featuring eight 16-bit datapointers for enhanced data handling capabilities.
• Integrated full CAN controller compliant with version 2.0 B supporting baudrates up to 1 MBaud.
• On-chip emulation support via Enhanced Hooks Technology allowing identical production and emulation chips.
• Includes a programmable 15-bit watchdog timer and oscillator watchdog for system reliability.

Applications

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

Procurement Notes

Verify the specific ordering code against official Infineon documentation to ensure correct package type and delivery format. Confirm that the OTP memory variant matches the required firmware programming constraints. Check for any RoHS compliance status updates or environmental declarations relevant to the manufacturing date code. Ensure compatibility with existing design-in tools and ICE-systems utilizing Enhanced Hooks technology.

Selection Notes

Select this component when a robust 8-bit solution with integrated CAN communication is required for automotive or industrial environments. The C505CA offers a balance of processing speed and peripheral integration suitable for applications needing fast response times. Consider the OTP memory limitation if frequent field updates are anticipated, as it cannot be reprogrammed like EEPROM variants.

Part Context

This part belongs to the C500 family of 8-bit single-chip microcontrollers produced by Infineon Technologies. The C505CA derivative specifically enhances the base C500 architecture by adding a full CAN module and increasing the XRAM size to 1 Kbyte compared to earlier versions. It serves as a bridge between standard 8051 compatibility and advanced automotive networking requirements.

Replacement Considerations

Direct substitutes include other C505CA variants with different memory types such as ROM (e.g., C505CA-4R). Cross-family migration may require significant architectural changes due to the unique datapointer and register set of the C500 core.
