Key Parameters

Substitute Part Grouping Explanation

Substitution of the AT28C010-15JI is determined by strict equivalence across the following electrical and mechanical parameters:

• Memory capacity and organization (1Mbit, 128K x 8 configuration)
• Parallel interface architecture
• Access time specification (150 ns)
• Write cycle time (10 ms)
• Supply voltage range (4.5V ~ 5.5V)
• Operating temperature range (-40°C ~ 85°C)
• Physical package format (32-PLCC with J-Lead configuration)
• Mounting technology (Surface Mount)

The AT28C010-15JU meets all these criteria and qualifies as a direct electrical and mechanical equivalent.

Parameter Comparison

Engineering Selection Recommendations
