C505CA4EMCAKXUMA1

Overview

The Infineon C505CA4EMCAKXUMA1 is an 8-bit single-chip microcontroller from the C500 family, based on the standard 8051 architecture. It features a 32 Kbyte OTP program memory and 1 Kbyte of internal XRAM. The device includes a Full CAN controller compliant with version 2.0 B, supporting up to 1 Mbaud rates at frequencies above 8 MHz. It operates at clock frequencies up to 20 MHz with instruction cycle times as low as 300 ns. The unit integrates a 10-bit A/D converter with eight analog inputs, three 16-bit timers/counters, and a full-duplex USART.

Feature Summary

• Superset of the standard 8051 architecture featuring eight 16-bit datapointers for enhanced data handling.
• Integrated Full CAN controller (version 2.0 B) with dedicated register space in external data memory.
• On-chip emulation support via Enhanced Hooks Technology for production chip debugging without bond-out requirements.
• Comprehensive peripheral set including a 10-bit A/D converter, programmable watchdog timer, and multiple power-saving modes.

Applications

• Automotive electronic control units requiring robust CAN communication
• Industrial automation systems utilizing high-speed serial interfaces
• Embedded applications needing precise timing via capture/compare channels

Procurement Notes

Verify the specific ordering code suffix against official Infineon documentation to confirm package type and delivery format. Ensure compatibility with the required temperature range specifications before procurement. Cross-reference the part number with current product availability lists to confirm active status or obsolescence.

Selection Notes

Select this component when a standard 8051 core requires extended memory capacity and integrated CAN functionality. The C505CA variant provides the necessary 10-bit ADC resolution and larger XRAM compared to earlier derivatives. Consider the P-MQFP-44 package constraints and pinout compatibility with existing C501 or C504 designs during system integration.

Part Context

This microcontroller belongs to the C500 family, which bridges standard 8051 compatibility with advanced embedded features. The C505CA derivative specifically targets applications demanding both digital I/O flexibility and analog signal processing capabilities within a single chip environment.

Replacement Considerations

C505A-4E variants offer identical memory and peripheral configurations but lack the integrated CAN controller. Standard C505/C505C versions provide lower memory capacities and different ADC resolutions.
