67C4013-15NL

Overview

The 67C4013-15NL is an asynchronous FIFO memory component manufactured by Advanced Micro Devices. It features a memory organization of 64 words by 4 bits and supports uni-directional data transfer. The device operates with a clock frequency of 15 MHz and requires a supply voltage range of 4.5 V to 5.5 V. Maximum supply current is specified at 45 mA. It is housed in a 20-pin CLCC package.

Feature Summary

• Asynchronous operation for independent read and write clock domains
• Uni-directional data flow architecture
• Low-power standby capability suitable for battery systems

Applications

• Ultra-low power system integration
• Battery-powered electronic devices
• Data buffering in microcontroller interfaces

Procurement Notes

Verify the manufacturer designation, as the part originates from Advanced Micro Devices, which was acquired by AMD. Confirm the specific suffix '15NL' corresponds to the 15 MHz speed grade and 20-CLCC package. Ensure compatibility with 4.5 V to 5.5 V logic levels before procurement.

Selection Notes

Select this component when a small-capacity, uni-directional asynchronous buffer is required. The 15 MHz speed rating suits moderate-speed data transfers. Consider the 4-bit width and 64-word depth for simple buffering tasks where complex bidirectional control is unnecessary.

Part Context

This part belongs to the 67C401/13 series of first-in-first-out memories. It shares architectural similarities with the 67C4013-10NL but offers higher clock performance. The series is designed for cascading and general-purpose data storage applications in digital circuits.

Replacement Considerations

The 67C4013-10NL is a verified substitute within the same family, offering identical memory structure but with a 10 MHz clock specification. Verify that the reduced speed meets system timing requirements before substitution.
