• Manufacturer Part Number: EDI88512C
• Description: 512Kx8 Monolithic SRAM, CMOS
• Manufacturer: WEDC [White Electronic Designs Corporation]

NOTE:
Stress greater than those listed under “Absolute Maximum Ratings” may cause
permanent damage to the device. This is a stress rating only and func tion al operation
of the device at these or any other conditions greater than those in di cat ed in the
operational sections of this spec i fi ca tion is not implied. Exposure to absolute maximum
rating conditions for extended periods may affect reliability.
NOTE: DC test conditions: Vil = 0.3V, Vih = Vcc -0.3V
