Overview
The 67C401-10NSHRP is an asynchronous FIFO memory integrated circuit manufactured by Advanced Micro Devices. It features a memory organization of 64 words by 4 bits, providing a total capacity of 256 bits. The device operates with a maximum data rate of 10 MHz and supports a supply voltage range of 4.5 V to 5.5 V. It is housed in a 20-pin DIP package and functions within a temperature range of 0°C to 70°C.
Feature Summary
- Asynchronous operation mode for independent read and write clock domains
- Uni-directional bus interface architecture
- Programmable expansion type capability
Applications
- Data buffering between asynchronous systems
- Level shifting between different voltage domains
- Temporary storage in digital signal processing chains
Procurement Notes
Verify the specific suffix 'SHRP' against official AMD documentation to confirm exact packaging or environmental qualifications. Ensure the 20-pin DIP form factor matches the target PCB footprint. Confirm RoHS compliance status as sources indicate non-compliance. Validate the 4.5V to 5.5V operating range against system power rails.
Selection Notes
Select this component when a small-capacity, asynchronous FIFO is required for uni-directional data flow. The 64x4 depth suits applications needing minimal buffering latency. The 10 MHz speed rating limits suitability for high-speed interfaces. Consider the 20-pin DIP package constraints for modern surface-mount designs.
Part Context
This part belongs to the 67C401 series of asynchronous FIFOs from Advanced Micro Devices. It represents a legacy CMOS technology component designed for general-purpose memory buffering. The series typically offers various pin counts and depths to accommodate different integration requirements in older digital systems.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Verify compatibility with direct replacements by matching the 64x4 organization, 10 MHz speed, and 20-pin DIP package specifications.
