Overview
The 67C401-25J is an asynchronous FIFO memory component manufactured by Advanced Micro Devices. It provides a storage capacity of 64 words by 4 bits, organized as a uni-directional buffer. The device operates within a supply voltage range of 4.5V to 5.5V and supports data rates up to 25MHz, as indicated by the -25 suffix. It is housed in a 20-pin PLCC (9x9mm) surface-mount package with J-leads. This CMOS RAM-based memory product is designed for high-performance buffering applications requiring first-in first-out data handling.
Feature Summary
- Uni-directional asynchronous data buffering architecture
- CMOS RAM-based construction for high performance
- Supports cascading for expanded memory depth
Applications
- Data rate conversion between different clock domains
- Buffering data streams in communication interfaces
- Temporary storage in digital signal processing systems
Procurement Notes
Verify the specific speed grade suffix matches the required operational frequency. Confirm the package type is compatible with the target PCB footprint. Check RoHS compliance status if environmental regulations apply. Ensure the manufacturer source is authorized to guarantee component authenticity and traceability.
Selection Notes
Select this component when a 64-word by 4-bit asynchronous buffer is required. Consider the 25MHz maximum operating frequency against system timing requirements. Evaluate the 20-PLCC package constraints for surface mount assembly. Compare against other 67C40X series variants if different speeds or widths are needed.
Part Context
This part belongs to the 67C40X/XX series of high-performance CMOS FIFOs. The series includes variants like 67C401 and 67C402, offering different bit widths and speeds. These devices are designed for applications requiring reliable data buffering and synchronization between asynchronous systems.
Replacement Considerations
Check for direct substitutes within the 67C401 series with different speed grades, such as 67C401-10NL or 67C401-15N, if lower frequencies suffice. Verify pin compatibility and electrical specifications before substitution.
