5V, Byte Alterable EEPROM
The X28HC256 is a second generation high performance
CMOS 32k x 8 EEPROM. It is fabricated with Intersil’s
proprietary, textured poly floating gate technology, providing
a highly reliable 5V only nonvolatile memory.
The X28HC256 supports a 128-byte page write operation,
effectively providing a 24µs/byte write cycle, and enabling
the entire memory to be typically rewritten in less than 0.8
seconds. The X28HC256 also features DATA Polling and
Toggle Bit Polling, two methods of providing early end of
write detection. The X28HC256 also supports the JEDEC
standard Software Data Protection feature for protecting
against inadvertent writes during power-up and power-down.
Endurance for the X28HC256 is specified as a minimum
1,000,000 write cycles per byte and an inherent data
retention of 100 years.

... Pin Descriptions Addresses ( 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 ...

... Page Write Operation The page write feature of the X28HC256 allows the entire memory to be written in typically 0.8 seconds. Page write allows up to one hundred twenty-eight bytes of data to be consecutively written to the X28HC256, prior to the commencement of the internal programming cycle. The host ...

... Software Data Protection The X28HC256 offers a software-controlled data protection feature. The X28HC256 is shipped from Intersil with the software data protection NOT ENABLED; that is, the device will be in the standard operating mode. In this mode data should be protected during power-up/down operations through the use of external circuits ...

Software Algorithm Selecting the software data protection mode requires the host system to precede data write operations by a series of three write operations to three specific addresses. Refer to Figure 6 and 7 for the sequence. The three-byte sequence ...

... Because the X28HC256 has two power modes, standby 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 l/Os ...

... 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. 10. The timings shown above are unique to page write operations. Individual byte load operations within the page write must conform to either the controlled write cycle timing ...
