C515C8EMCAFXQMA1

Overview

The Infineon C515C8EMCAFXQMA1 is an 8-bit microcontroller based on the 8051 architecture, housed in a P-MQFP-80-1 package. It features 64 Kbytes of one-time programmable (OTP) program memory and 2 Kbytes of internal XRAM alongside 256 bytes of RAM. The device supports up to 10 MHz external operating frequency with a 600 ns instruction cycle time at that speed. Key peripherals include a Full-CAN controller, a 10-bit ADC with eight inputs, three 16-bit timers, and synchronous serial interfaces.

Feature Summary

• Integrates a Full-CAN controller with register data located in external memory area for robust communication.
• Includes Enhanced Hooks Technology for on-chip emulation support during development.
• Features multiple power-saving modes including idle, slow-down, and software/hardware power-down options.
• Provides eight 16-bit datapointers as an enhancement over standard 8051 architectures.

Applications

• Automotive control systems requiring CAN bus connectivity
• Industrial embedded controllers utilizing OTP memory
• Systems needing precise analog signal processing via integrated ADC

Procurement Notes

Verify the specific ordering suffix against official Infineon documentation to confirm package type and temperature range. Ensure compatibility with existing design constraints regarding the P-MQFP-80-1 footprint. Confirm that the OTP nature of the memory aligns with production programming capabilities and lifecycle requirements.

Selection Notes

Select this component when a standard 8051 core requires extended peripheral integration such as hardware CAN support. Consider the OTP memory variant if non-volatile storage is needed without the cost of mask ROM. Evaluate the 10 MHz maximum clock speed against real-time processing demands and power consumption profiles.

Part Context

This part belongs to the C515C series, which serves as an enhanced upgrade to the SAB 80C515A. It adds significant peripheral density compared to its predecessors, specifically integrating full CAN capability and additional RAM. The series maintains upward compatibility with the 80C515A instruction set while expanding address space handling through multiple datapointers.

Replacement Considerations

The C515C-8R is the ROM-based equivalent within the same family. Direct substitution requires verifying memory type differences and ensuring pinout compatibility across the P-MQFP-80-1 package variants.
