The EDI8F32512V is a high speed 16Mb Static RAM module
organized as 512K words by 32 bits. This module is constructed
from four 512Kx8 Static RAMs in SOJ packages on an epoxy
laminate (FR4) board.
Four chip enables (E-E3) are used to independently enable
the four bytes. Reading or writing can be executed on individual
bytes or any combination of multiple bytes through proper use of
selects.
The EDI8F32512V is offered in 72 pin ZIP and 72 lead SIMM
packages, which enable 16Mb of memory to be placed in less
than 1.3 square inches of board space.
All inputs and outputs are TTL compatible and operate from a
single 3.3V supply. Fully asynchronous circuitry requires no
clocks or refreshing for operation and provides equal access and
cycle times for ease of use.
Pins PD0- PD3, are used to identify module memory density in
applications where alternate modules can be interchanged.

*Stress greater than those listed under "Absolute Maximum Ratings" may cause
permanent damage to the device. This is a stress rating only and functional operation
of the device at these or any other conditions greater than those indicated in the
operational sections of this specification is not implied. Exposure to absolute maximum
rating conditions for extended periods may affect reliability.
(note: For TEHQZ,TGHQZ and TWLQZ, CL = 5pF)
*Typical: TA = 25C, VCC = 5.0V
These parameters are sampled, not 100% tested.
