AS7C164A-15PIN

Overview

The AS7C164A-15PIN is a 64 Kbit CMOS static random access memory (SRAM) organized as 8K x 8 bits. It features a parallel interface with a maximum access time of 15 ns. The device operates within a supply voltage range of 4.5 V to 5.5 V and has a maximum power supply current of 140 mA. It supports surface mount installation in a 28-pin PDIP package. The component is rated for an industrial operating temperature range from -40°C to +85°C.

Feature Summary

• Provides non-volatile data retention characteristics typical of SRAM technology for rapid read/write operations
• Utilizes a standard parallel interface architecture for direct microprocessor connectivity
• Designed for industrial-grade environmental stability across wide temperature variations

Applications

• Industrial control systems requiring reliable short-term data storage
• Embedded applications needing fast buffer memory for data processing
• Consumer electronics utilizing 5V logic level interfaces

Procurement Notes

Verify the specific suffix PIN indicates the 28-pin PDIP package configuration against your schematic requirements. Confirm that the 15 ns access speed meets your system timing constraints. Ensure the 5V supply voltage aligns with your board's power distribution network. Check for RoHS compliance documentation if required by your manufacturing standards. Validate the industrial temperature rating suitability for your operational environment.

Selection Notes

Select this component when a 64 Kbit capacity is sufficient for the application design. Choose this part over faster variants if cost efficiency is prioritized alongside adequate 15 ns performance. Consider the through-hole PDIP package only if PCB layout constraints or mechanical mounting requirements necessitate this form factor. Verify compatibility with existing 5V logic families before integration.

Part Context

This part belongs to the Alliance Memory AS7C164A series of asynchronous SRAMs. It serves as a legacy replacement for older 64Kbit memory solutions in established designs. The series maintains pin-out compatibility with industry-standard equivalents, facilitating upgrades in existing hardware architectures without significant redesign efforts.

Replacement Considerations

AS7C164A-15JIN offers identical electrical specifications but utilizes a SOJ package instead of PDIP.
