falling edge of
WE or CE, whichever occurs last. Data,
conversely, is latched on the rising edge of
WE or CE,
whichever occurs first. Once initiated, a byte write cycle
automatically erases the addressed byte and the new
data is written within 5 ms.
Page Write
The page write mode of the CAT28C65B (essentially an
extended BYTE WRITE mode) allows from 1 to 32 bytes
of data to be programmed within a single EEPROM write
cycle. This effectively reduces the byte-write time by a
factor of 32.
Following an initial WRITE operation (
WE pulsed low, for
tWP, and then high) the page write mode can begin by
issuing sequential
WE pulses, which load the address
and data bytes into a 32 byte temporary buffer. The page
address where data is to be written, specified by bits A5
to A12, is latched on the last falling edge of WE. Each
byte within the page is defined by address bits A0 to A4
