Overview
The CY7C4265-10AIKJ is an asynchronous FIFO memory IC manufactured by Cypress Semiconductor Corp. It features a storage capacity of 2K x 9 bits and supports unidirectional data transfer. The device operates at a maximum clock frequency of 100MHz with an access time of 8ns. It is housed in a 64-TQFP surface-mount package measuring 14x14mm. The component functions within a voltage range of 4.5V to 5.5V, drawing a maximum supply current of 35mA. It is rated for industrial operating temperatures between -40°C and 85°C.
Feature Summary
- Asynchronous operation supporting independent read and write clocks
- Unidirectional data flow architecture
- High-speed performance with 100MHz clock capability
Applications
- Data buffering in high-speed digital systems
- Clock domain crossing interfaces
- Protocol conversion buffers
Procurement Notes
Verify the specific suffix 'AIKJ' to confirm the 64-TQFP package and industrial temperature grade (-40°C to 85°C). Ensure compatibility with 4.5V to 5.5V logic levels. Confirm RoHS status as applicable for your assembly requirements. Check part status for availability as distribution may vary.
Selection Notes
Select this component when asynchronous buffering is required for 9-bit wide data paths. The 2K depth suits moderate buffer sizes. Verify that the 8ns access time meets system timing constraints. Ensure the TQFP package fits the PCB layout. Compare against synchronous alternatives if clock alignment is feasible.
Part Context
This part belongs to the CY7C4265 series of FIFO memories from Cypress. The series includes variants with different depths and speeds. The CY7C4265 specifically offers 2K, 8K, and 16K depth options. The AIKJ designation indicates the asynchronous type with specific packaging and temperature ratings.
Replacement Considerations
Check for CY7C4265 variants with different suffixes for package or temperature changes. Verify functional equivalence with other asynchronous FIFOs offering 2K x 9 capacity. Ensure pinout compatibility before substitution.
