READ: The AT28C64 is accessed like a Static RAM. When CE and OE are low and WE is high, the data stored at the memory location determined by the address pins is asserted on the outputs. The outputs are put in a high im- pedance state whenever CE or OE is high. This dual line control gives designers increased flexibility in preventing bus contention.
The M27C64A has two control functions, both of which must be logically active in order to obtain data at the outputs. Chip Enable (E) is the power control and should be used for device selection. Output Enable (G) is the output control and should
DESCRIPTION The devices are manufactured using high voltage Multi Epitaxial Planar technology for high switching speeds and medium voltage capability. They use a Cellular Emitter structure with planar edge termination to enhance switching speeds while maintaining the wide RBSOA. The devices are designed for use in lighting applications and low cost switch-mode power supplies.
