Infineon Technologies C515C8EMCAFXUMA1

Overview

C515C8EMCAFXUMA1 from Infineon Technologies is an 8-bit single-chip microcontroller with full-CAN controller, 64 KB on-chip OTP program memory, 2 KB XRAM, and 10-bit ADC (8-channel). It operates up to 10 MHz external clock (1 µs instruction cycle at 6 MHz), features Enhanced Hooks Technology™ for on-chip emulation, and targets automotive and industrial CAN-based control systems.

For engineers reviewing the C515C8EMCAFXUMA1 datasheet, C515C8EMCAFXUMA1 pinout, C515C8EMCAFXUMA1 application, or C515C8EMCAFXUMA1 equivalent, key selection criteria include CAN bus compliance (ISO 11898), OTP programmability, integrated 10-bit ADC calibration, power-down wake-up via INT0/RXDC, and P-MQFP-80-1 package compatibility.

Technical Context

The C515C8EMCAFXUMA1 implements a superset of the 8051 architecture with eight datapointers and seventeen interrupt vectors across four priority levels. Its on-chip Full-CAN controller supports up to 1 MBaud at 8–10 MHz operation and maps 256 bytes into external data memory space.

It integrates a 10-bit successive-approximation ADC with built-in self-calibration, three 16-bit timer/counters (Timer 2 supporting capture/compare), and dual serial interfaces: full-duplex USART with programmable baudrate generator and SPI-compatible SSC with master/slave capability, LSB/MSB-first selection, and 2.5 MHz max transfer rate at 10 MHz clock.

FAQ

What is the maximum CAN bit rate supported by the C515C8EMCAFXUMA1?

The C515C8EMCAFXUMA1's on-chip Full-CAN controller supports up to 1 MBaud under standard ISO 11898-1 conditions. Achievable bit rate depends on oscillator frequency (8–10 MHz) and bus length; at 10 MHz clock, 500 kBit/s is typical for 40 m bus length with proper termination.

Does the C515C8EMCAFXUMA1 require an external CAN transceiver?

Yes - the C515C8EMCAFXUMA1 contains only the CAN protocol controller (CAN core), not the physical layer (PHY). An external ISO 11898-compliant transceiver (e.g., Infineon TLE6250 or TJA1042) must be used to drive the differential CAN_H/CAN_L bus lines.

Can the on-chip 10-bit ADC operate during power-down mode?

No - the ADC is disabled in all power-down modes (software and hardware). It remains functional only in active, idle, and slow-down modes. Wake-up must occur first, then ADC initialization and conversion sequence must be re-executed.

Is the C515C8EMCAFXUMA1 qualified for automotive AEC-Q100 stress testing?

Yes - the SAF-C515C variant (which includes C515C8EMCAFXUMA1) is rated for –40 °C to +85 °C and qualified per AEC-Q100 Grade 2. Full qualification documentation, including HTOL and TC testing reports, is available from Infineon upon NDA.
