AS6C6264-55PIN

Overview

The AS6C6264-55PIN is a CMOS static random-access memory (SRAM) manufactured by Alliance Memory, Inc. It features a storage capacity of 64 kbit organized as 8k x 8 bits. The device supports a parallel interface with an access time of 55 ns. It operates within a supply voltage range of 2.7 V to 5.5 V and has a maximum power supply current of 45 mA. The component is designed for through-hole installation in a PDIP-28 package. It functions reliably across a temperature range from -40°C to +85°C.

Feature Summary

• Asynchronous CMOS SRAM technology providing non-volatile data retention during operation without refresh cycles.
• Parallel interface architecture enabling direct connection to microprocessors and digital logic systems.
• Wide operating voltage compatibility supporting both 3V and 5V logic levels for flexible system integration.

Applications

• Embedded systems requiring fast local data storage
• Industrial control units needing reliable memory in harsh environments
• Consumer electronics utilizing standard parallel bus architectures

Procurement Notes

Verify the specific suffix PIN confirms the PDIP-28 through-hole package variant when sourcing. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as regulatory updates may occur. Ensure the 55 ns speed grade matches the target system timing requirements before finalizing procurement decisions.

Selection Notes

Select this component for designs requiring through-hole mounting and robust industrial temperature performance. Compare against surface-mount alternatives like the AS6C6264-55STIN if board space constraints dictate SMD solutions. Validate that the 8k x 8 organization aligns with the application's memory addressing needs.

Part Context

This part belongs to the Alliance Memory AS6C6264 series of low-power CMOS SRAMs. The series offers various speed grades and packaging options to suit different design constraints. The AS6C6264-55PIN specifically addresses applications needing durable through-hole connectivity with proven asynchronous memory performance.

Replacement Considerations

The U6264BDK07LLG1 is listed as a direct substitute, though it specifies a 70 ns access time compared to the 55 ns of the AS6C6264-55PIN. Verify timing margins in the host circuit before substituting.
