Overview
The C505CA4EMCABXQMA1 is an 8-bit microcontroller from the Infineon C500 family, based on the 8051 architecture. It features a 32 KB One-Time Programmable (OTP) memory and 1 KB of XRAM. The device operates at frequencies up to 20 MHz and includes a full CAN controller compliant with version 2.0 B. It integrates a 10-bit A/D converter with eight analog inputs, three timers/counters, and a USART. The unit is housed in a P-MQFP-44 package.
Feature Summary
- Integrates a full CAN controller compliant with version 2.0 B for high-speed communication
- Includes a 10-bit A/D converter with eight analog input channels
- Features Enhanced Hooks Technology for on-chip emulation support
- Provides eight 16-bit datapointers for efficient external memory addressing
Applications
- Automotive body electronics
- Industrial control systems
- Distributed sensor networks
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm temperature range and delivery type. Confirm that the OTP variant matches the required firmware programming constraints. Ensure compatibility with existing P-MQFP-44 footprints and voltage levels during integration.
Selection Notes
Select this component when a robust 8051-compatible core with integrated CAN functionality is required. It is suitable for applications needing 32 KB of non-volatile storage and high-speed serial communication. Consider the 10-bit ADC resolution and multiple datapointers for complex data handling tasks.
Part Context
This part belongs to the C500 family of 8-bit single-chip microcontrollers. It serves as a superset of the standard 8051 architecture, offering enhanced peripherals such as additional datapointers and advanced timer modules. The C505CA derivative specifically targets automotive and industrial environments requiring reliable CAN bus connectivity.
Replacement Considerations
Compatible derivatives within the C500 family include C505A-4E variants without CAN and C505C-4R variants with ROM instead of OTP. Verify pinout compatibility with C501, C504, and C511/C513 families if migrating from other controllers.
