67C401-10NL

Overview

The AMD 67C401-10NL is an asynchronous FIFO memory IC with a 64 x 4 configuration. It operates at a data rate of 10MHz and features uni-directional data flow. The component is housed in a 20-pin PLCC package measuring 9x9 mm. It supports surface mount mounting and functions within an operating temperature range of 0°C to 70°C.

Feature Summary

• Asynchronous operation for independent clock domains
• Uni-directional data transfer capability
• Compact 20-pin PLCC surface mount packaging

Applications

• Temporary data storage and buffering
• Digital workflow streamlining
• Interface bridging between different speed components

Procurement Notes

Verify the specific suffix '10NL' against official Microchip or Advanced Micro Devices documentation to confirm the 10MHz speed grade and commercial temperature range. Ensure the 20-PLCC package matches the design footprint. Confirm active status through authorized distributors, as availability may vary by region.

Selection Notes

Select this part when a small depth FIFO is required for uni-directional buffering. The 64x4 word size suits low-bandwidth applications. Consider the 10MHz limit for timing constraints. Compare with higher-speed variants like the -25J if faster throughput is needed, noting potential package differences.

Part Context

This component belongs to the AMD 67C401 series of asynchronous FIFOs. It shares the 64x4 architecture with other variants such as the 67C401-25J and 67C401-15NL. The series provides flexible memory buffering solutions for digital logic designs requiring temporary data holding capabilities.

Replacement Considerations

The 67C401-25J offers similar functionality but with a 25MHz data rate. Verify pin compatibility and thermal requirements before substitution. Other series members like 67C4023 differ significantly in depth and width.
