Description
The SYS8V512FK is plastic 4M Static RAM Module
housed in a standard 32 pin Dual-In-Line package
organised as 512K x 8. The module is designed to
operate at low Vcc (3V ± 10%).
The module utilises fast SRAMs housed in SOP
packages, and uses double sided surface mount
techniques, buried decoder and dual board
construction to achieve a very high density module.
The module has Chip Select, Write Enable and
Output Enable control inputs; the Output Enable
pin allows faster access times than address access
during a Read Cycle.
