AN2136SC

Overview

The AN2136SC is a ROMless USB microcontroller from the EZ-USB™ family, manufactured by Infineon Technologies. It integrates an enhanced 8051 core processor with 8K x 8 RAM and operates at a clock frequency of 24 MHz. The device supports I²C and USB interfaces, providing 8 programmable I/O ports. It functions within a supply voltage range of 3V to 3.6V and operates in temperatures between 0°C and 70°C. Packaged in a 44-QFP surface-mount format, this component is currently marked as obsolete.

Feature Summary

• Integrated EZ-USB™ controller with full-speed USB interface
• Enhanced 8051 microprocessor core with 8K RAM
• Built-in I²C master controller for system communication
• Supports ReNumeration™ functionality for dynamic device configuration

Applications

• USB bus data acquisition systems
• FPGA configuration and control via PS mode
• High-speed bulk transfer applications

Procurement Notes

Verify component authenticity due to its discontinued status. Confirm RoHS compliance requirements, as the part does not meet current standards. Check for valid date codes and storage conditions prior to procurement to ensure operational reliability.

Selection Notes

Select this component only for legacy designs requiring specific EZ-USB architecture. Ensure firmware development tools support the 8051 core and verify that the 44-QFP package fits the target PCB layout constraints.

Part Context

Originally developed by Cypress Semiconductor Corporation, the AN2136SC belongs to the AN213x controller series. Following corporate acquisitions, manufacturing rights transferred to Infineon Technologies. The device serves as a foundational solution for embedded USB connectivity in older industrial and consumer electronics.

Replacement Considerations

No direct public substitutes are confirmed. Designers should evaluate modern EZ-USB FX or FX2LP derivatives for new implementations.
