29205BXA

Overview

The Intersil 29205BXA is an asynchronous CMOS static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 64 kilobits, organized as 8K words by 8 bits. The device utilizes a parallel memory interface for data transfer. Key electrical specifications include a maximum access time of 150 nanoseconds and a write cycle time of 150 nanoseconds. The component operates within a supply voltage range of 4.5 volts to 5.5 volts. It is housed in a 28-lead ceramic dual in-line package (CERDIP).

Feature Summary

• Asynchronous CMOS SRAM technology for volatile data storage.
• Parallel interface supporting standard memory bus connectivity.
• Fast 150 ns access and write cycle times for efficient data retrieval.

Applications

• Embedded systems requiring fast local data storage.
• Industrial control units needing reliable volatile memory.
• Communication equipment buffer applications.

Procurement Notes

Verify the manufacturer designation, as the part may be listed under Xicor or Intersil due to corporate divisions. Confirm the package type is 28-CERDIP and check RoHS compliance status, as some sources indicate lead-free versions. Ensure the specific suffix matches the required speed grade and voltage tolerance before ordering.

Selection Notes

Select this component when a parallel interface SRAM with 64Kbit capacity is required. The 150 ns speed class suits moderate-speed asynchronous applications. Consider the CERDIP package for through-hole mounting requirements. Verify that the 4.5V to 5.5V operating range aligns with the system power supply design.

Part Context

This device belongs to the family of high-performance static RAMs designed for general-purpose memory applications. It serves as a non-volatile-free storage solution where rapid read/write operations are necessary. The integration of CMOS technology ensures low power consumption relative to older bipolar technologies while maintaining compatibility with standard logic families.

Replacement Considerations

Check for direct pin-compatible replacements from Intersil or Renesas with identical 8Kx8 organization and 150 ns speed. Verify that any substitute maintains the same 28-CERDIP package and 5V supply requirements. Cross-reference datasheets to ensure functional equivalence in asynchronous operation modes.
