Infineon Technologies C515C8EMCAFXUMA2

Overview

C515C8EMCAFXUMA2 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 C515C8EMCAFXUMA2 datasheet, C515C8EMCAFXUMA2 pinout, C515C8EMCAFXUMA2 application, or C515C8EMCAFXUMA2 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 package compatibility with legacy SAB 80C515A designs.

Technical Context

The C515C8EMCAFXUMA2 implements a superset of the 8051 architecture with eight datapointers and seventeen interrupt vectors across four priority levels. Its integrated Full-CAN controller supports up to 1 MBaud at 8–10 MHz operation and maps 256 bytes into external data memory space.

It includes three 16-bit timer/counters (Timer 2 with capture/compare), a self-calibrating 10-bit ADC, dual serial interfaces (USART + SPI-compatible SSC), and five power-saving modes - including hardware/software power-down with wake-up on INT0 or RXDC - all enabled by dedicated oscillator watchdog and CPU running status output.

Key Specifications

Pinout & Package

P-MQFP-80-1 package: 80-pin quad flat pack with exposed thermal pad, 0.65 mm pitch, body size 14 × 14 mm, compliant with JEDEC MO-159. Features multiple VDD/VSS pairs for analog/digital supply separation and EMI reduction.

FAQ

What is the maximum CAN bit rate supported by the C515C8EMCAFXUMA2?

The C515C8EMCAFXUMA2 supports up to 1 MBaud on its integrated Full-CAN controller when operating at 8–10 MHz external clock frequency. Bit timing is configurable via BTR0/BTR1 registers, and the controller complies fully with ISO 11898-1 physical layer timing requirements for standard and extended frames.

Does the C515C8EMCAFXUMA2 require an external CAN transceiver?

Yes - the C515C8EMCAFXUMA2 contains only the CAN protocol controller (CAN core), not the physical layer transceiver. An external ISO 11898-compliant transceiver (e.g., Infineon TLE6250 or TJA1040) must be used to drive the CAN bus differential pair (CANH/CANL).

Can the on-chip OTP memory be reprogrammed after initial programming?

No - the C515C8EMCAFXUMA2 uses one-time programmable (OTP) memory. Once programmed, the 64 KB program memory cannot be erased or rewritten. Programming occurs during final test using standard Infineon OTP programmers; verify firmware correctness before committing to OTP.

What power-saving modes are available and how are they exited?

The device supports Idle, Slow-down, Software Power-down, and Hardware Power-down modes. Exit conditions include: INT0 (P3.2) edge for all modes except Hardware Power-down; RXDC (P4.7) edge for Software Power-down only; and external reset or oscillator restart for Hardware Power-down. CPU state is preserved in Idle and Slow-down modes.
