Description
The UM2366 and UM2366A high performance Read Only
Memories are organized 8192 words by 8 bits with access
times from 200 ns to 450 ns. The ROMs are designed to be .
compatible with all microprocessor and similar applications
where high performance, large bit storage and simple inter-
facing are important design considerations. Both ROMs
conform to the JEDEC approved pinout for 28 pin 64K
ROMs.
The UM2366 offers the simplest operation (no power
down.) Its four programmable chip selects allow up to
sixteen 64K ROMs to be OR-tied without external decod-
ing.
The UM2366A offers an automatic power down feature.
Pin Configuration
Power down is controlled by the Chip Enable (CE) input.
When CE goes high, the device will automatically power
down and remain in a low power standby mode as long as
CE remains high. This unique feature provides system level
power savings as much as 90%. An additional feature of the
UM2366A is the Output Enable (OE) function. This
eliminates bus contention in multiple bus microprocessor
systems. The two programmable Chip Selects (CS) allow
up to four 64K ROMs to be OR-tied without external
decoding.
Both the UM2366 and UM2~66A are pin compatible with
the 2764 EPROM thus eliminating the need to redesign
printed circuit boards for volume mask programmed ROMs
after prototyping with EPROMs.
