Key Parameters

Substitute Part Grouping Explanation

Substitution of the 23LCV512-E/P is determined by the following critical parameters: memory capacity (512Kbit), memory organization (64K x 8), physical package (8-DIP through-hole), and operating temperature range (-40°C to 125°C). The 23A512-E/P qualifies as a substitute based on matching memory size, organization, package type, and temperature specifications. Both devices maintain identical mechanical compatibility and thermal operating envelope. The substitute part is classified as active product status, providing continued availability and supply chain support.

Parameter Comparison

Engineering Selection Recommendations

The 23A512-E/P serves as the active substitute for the obsolete 23LCV512-E/P. Both components share identical memory capacity, organization, package configuration, and thermal operating range. The substitute maintains ROHS3 compliance and MSL Level 1 rating, consistent with the original part. Selection of the 23A512-E/P is supported by its active product status, ensuring ongoing manufacturer support and supply availability. Both devices are manufactured by Microchip Technology, maintaining design continuity within the same product family.

Frequently Asked Questions (FAQ)

Q: Can the 23A512-E/P directly replace the 23LCV512-E/P in existing designs?

A: Physical and thermal compatibility is confirmed through matching 8-DIP package dimensions and identical -40°C to 125°C operating temperature range. Functional compatibility is established through identical 512Kbit memory capacity and 64K x 8 organization. Interface differences (Dual I/O versus Quad I/O) and clock frequency variation (20 MHz versus 16 MHz) require circuit-level evaluation for specific applications.

Q: What are the key differences between these substitute parts?

A: The primary differences are memory interface type (Dual I/O versus Quad I/O), clock frequency (20 MHz versus 16 MHz), and supply voltage range (2.5V ~ 5.5V versus 1.7V ~ 2.2V). Memory capacity and package form factor remain identical.

Q: Why is the 23LCV512-E/P classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The 23A512-E/P, classified as active, represents the current production alternative within the Microchip 512Kbit SRAM product line.

Q: Are both parts RoHS compliant?

A: Both the 23LCV512-E/P and 23A512-E/P are ROHS3 compliant with MSL Level 1 rating, meeting environmental and reliability standards for industrial applications.
