... JEDEC approved pinout for byte-wide memories, compatible with industry standard EPROMs. The X28HT010 supports a 256-byte page write opera- tion, effectively providing a 19 s/byte write cycle and enabling the entire memory to be typically written in less than 2.5 seconds. 2 Xicor E PROMs are designed and tested for applica- tions requiring extended endurance ...

... X28HT010 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 X28HT010 has two power modes, standby through A ) for and active, proper decoupling of the memory array 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 ...

... 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. ...
