Product details
Overview
C515C8EMCAFXQMA1 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 C515C8EMCAFXQMA1 datasheet, C515C8EMCAFXQMA1 pinout, C515C8EMCAFXQMA1 application, or C515C8EMCAFXQMA1 equivalent, key selection criteria include CAN bus compliance (ISO 11898), OTP memory security, power-down wake-up via INT0/RXDC, and P-MQFP-80-1 thermal/mechanical suitability for embedded ECU designs.
Technical Context
The C515C8EMCAFXQMA1 implements an enhanced 8051-compatible CPU core with eight datapointers and four priority-level interrupt vectors. Its integrated Full-CAN controller supports up to 1 MBaud at 8–10 MHz operation and maps 256 bytes of CAN registers into external data memory space.
It includes three 16-bit timers (Timer 2 supports capture/compare), a self-calibrating 10-bit ADC with multiplexed analog inputs, and dual serial interfaces: USART (full-duplex, programmable baud rate) and SSC (SPI-compatible, master/slave, 2.5 MHz max at 10 MHz CPU).
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit CAN microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| C515C-8RM | 64 KB mask-ROM instead of OTP; no RXDC wake-up capability; CAN controller always active | Suitable for high-volume, fixed-firmware deployments where field updates are unnecessary | Select when firmware is finalized and cost-per-unit optimization outweighs programming flexibility |
| C517C-8EM | Enhanced derivative with larger XRAM (4 KB), additional timer, and extended CAN message objects (32 vs. 16) | Better suited for complex CAN FD gateway or multi-bus routing where memory and object count are limiting | Choose when migrating from C515C and requiring higher CAN throughput or deeper message buffering |
Compared with C515C-8RM, the C515C8EMCAFXQMA1 offers field-programmability and dual wake-up sources; compared with C517C-8EM, it trades memory and CAN object depth for lower cost and proven qualification in legacy automotive ECUs.

FAQ
What is the maximum CAN bit rate supported by the C515C8EMCAFXQMA1?
The C515C8EMCAFXQMA1 supports up to 1 MBaud on the CAN bus when operating at 8–10 MHz external clock frequency. This complies with ISO 11898-2 for high-speed CAN and is validated for error-free transmission over 40 m cable length with standard termination.
Does the C515C8EMCAFXQMA1 require an external CAN transceiver?
Yes - the C515C8EMCAFXQMA1 integrates only the CAN protocol controller and does not include the physical layer driver. An external ISO 11898-compliant transceiver (e.g., Infineon TLE6250 or TI SN65HVD230) must be used to drive the CANH/CANL differential bus lines.
Can the on-chip OTP memory be reprogrammed after initial programming?
No - the C515C8EMCAFXQMA1's 64 KB on-chip OTP memory is one-time programmable. Once written, its contents cannot be erased or rewritten. Programming is performed using standard Infineon OTP programmers (e.g., UPM-2000) under controlled voltage and timing conditions.
What power-saving modes are available and how are they exited?
The device supports slow-down, idle, software power-down, and hardware power-down modes. Software power-down is exited via INT0 (P3.2) or RXDC (P4.7); hardware power-down requires external reset assertion. All modes retain RAM content except hardware power-down, which loses XRAM unless externally held.
