... DESCRIPTION The X28HT512 is an 64K x 8 CMOS E cated with Xicor’s proprietary, high performance, float- ing gate CMOS technology which provides Xicor prod- ucts superior high temperature performance character- istics. Like all Xicor programmable nonvolatile memo- ries the X28HT512 only device. The X28HT512 features the JEDEC approved pinout for bytewide memo- ries, compatible with industry standard EPROMS ...

... X28HT512 PIN DESCRIPTIONS Addresses (A – The Address inputs select an 8-bit memory location during a read or write operation. Chip Enable (CE) The Chip Enable input must be LOW to enable all read/ write operations. When CE is HIGH, power consumption is reduced. Output Enable (OE) The Output Enable input controls the data output buffers and is used to initiate read operations ...

... Because the X28HT512 has two power modes, standby through A ) for 7 15 and active, proper decoupling of the memory array is of prime concern. Enabling CE will cause transient current spikes. The magnitude of these spikes is dependent on the output capacitive loading of the I/Os. Therefore, the larger the array sharing a common bus, the larger the transient spikes ...

... Notes: (5) Between successive byte writes within a page write operation, OE can be strobed LOW: e.g. this can be done with CE and WE HIGH to fetch data from another memory device within the system for the next write; or with WE HIGH and CE LOW effectively performing a polling operation. ...
