C515C8EMCAFXUMA1

Overview

The C515C8EMCAFXUMA1 is an 8-bit microcontroller based on the 8051 architecture, manufactured by Infineon Technologies. It features a P-MQFP-80-1 package and includes 64 Kbytes of one-time programmable (OTP) program memory, 256 bytes of internal RAM, and 2 Kbytes of XRAM. 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, a USART, and an SSC interface.

Feature Summary

• Integrates a Full-CAN controller with 256 bytes of register/data space located in the external data memory area.
• Includes Enhanced Hooks Technology for on-chip emulation support and debugging capabilities.
• Features a 10-bit A/D converter with multiplexed inputs and built-in self-calibration functionality.
• Provides multiple power-saving modes including slow-down, idle, and software/hardware power-down options.

Applications

• Automotive electronic control units requiring CAN bus communication
• Industrial control systems utilizing serial interfaces and analog input processing
• Consumer electronics applications needing robust 8-bit processing with extended I/O capabilities

Procurement Notes

Verify the specific ordering suffix against the official Infineon product information document to confirm temperature range and delivery type. Ensure the OTP memory variant matches the application's programming requirements. Confirm package compatibility with the P-MQFP-80-1 footprint during PCB design validation.

Selection Notes

Select this component when an 8051-compatible core is required alongside integrated CAN connectivity and analog-to-digital conversion. Consider the OTP memory constraint for production volumes where reprogramming is not feasible. Evaluate the 10 MHz maximum clock speed against real-time processing demands and peripheral timing requirements.

Part Context

The C515C series represents an enhanced upgrade over the SAB 80C515A, adding a full CAN interface and synchronous serial capability. It belongs to the C5xx/C8xx family of 8-bit single-chip microcontrollers designed for applications demanding high integration and reliable communication protocols within automotive and industrial sectors.

Replacement Considerations

The C515C-8R serves as a ROM-based alternative within the same family. Verify pinout and memory type differences before substitution. No direct cross-model replacements are confirmed in public documentation.
