DESCRIPTION  
The CAT28C64B is manufactured using Catalyst’s  
advancedCMOSfloatinggatetechnology.Itisdesigned  
to endure 100,000 program/erase cycles and has a data  
retentionof100years.ThedeviceisavailableinJEDEC-  
approved 28-pin DIP, TSOP, SOIC, or, 32-pin PLCC  
package .  
The CAT28C64B is a fast, low power, 5V-only CMOS  
Parallel EEPROM organized as 8K x 8-bits. It requires a  
simple interface for in-system programming. On-chip  
address and data latches, self-timed write cycle with  
auto-clear and VCC power up/down write protection  
eliminate additional timing and protection hardware.  
DATA Polling and Toggle status bits signal the start and  
end of the self-timed write cycle. Additionally, the  
CAT28C64B features hardware and software write  
protection.

CAT28C64B  
Byte Write  
DEVICE OPERATION  
A write cycle is executed when both CE and WE are low,  
and OE is high. Write cycles can be initiated using either  
WE or CE, with the address input being latched on the  
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.  
Read  
Data stored in the CAT28C64B is transferred to the data  
bus when WE is held high, and both OE and CE are held  
low. The data bus is set to a high impedance state when  
either CE or OE goes high. This 2-line control architec-  
ture can be used to eliminate bus contention in a system  
environment.

CAT28C64B  
Page Write  
(which can be loaded in any order) during the first and  
subsequent write cycles. Each successive byte load  
cycle must begin within tBLC MAX of the rising edge of the  
preceding WE pulse. There is no page write window  
The page write mode of the CAT28C64B (essentially an  
extended BYTE WRITE mode) allows from 1 to 32 bytes  
ofdatatobeprogrammedwithinasingleEEPROMwrite  
cycle. This effectively reduces the byte-write time by a  
factor of 32.  
limitation as long as WE is pulsed low within tBLC MAX  
.
Upon completion of the page write sequence, WE must  
stay high a minimum of tBLC MAX for the internal auto-  
matic program cycle to commence. This programming  
cycle consists of an erase cycle, which erases any data  
that existed in each addressed cell, and a write cycle,  
whichwritesnewdatabackintothecell. Apagewritewill  
only write data to the locations that were addressed and  
will not rewrite the entire page.  
FollowinganinitialWRITEoperation(WEpulsedlow,for  
tWP, and then high) the page write mode can begin by  
issuing sequential WE pulses, which load the address  
anddatabytesintoa32bytetemporarybuffer. Thepage  
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

CAT28C64B  
DATA Polling  
Toggle Bit  
DATA polling is provided to indicate the completion of  
write cycle. Once a byte write or page write cycle is  
initiated, attempting to read the last byte written will  
output the complement of that data on I/O7 (I/O0I/O6  
are indeterminate) until the programming cycle is com-  
plete. Upon completion of the self-timed write cycle, all  
I/Os will output true data during a read cycle.  
In addition to the DATA Polling feature, the device offers  
an additional method for determining the completion of  
a write cycle. While a write cycle is in progress, reading  
data from the device will result in I/O6 toggling between  
one and zero. However, once the write is complete, I/O6  
stops toggling and valid data can be read from the  
device.

HARDWARE DATA PROTECTION  
(4) Noise pulses of less than 20 ns on the WE or CE  
inputs will not result in a write cycle.  
Thefollowingisalistofhardwaredataprotectionfeatures  
that are incorporated into the CAT28C64B.  
SOFTWARE DATA PROTECTION  
(1) VCC sense provides for write protection when VCC  
falls below 3.5V min.  
The CAT28C64B features a software controlled data  
protectionschemewhich, onceenabled, requiresadata  
algorithmtobeissuedtothedevicebeforeawritecanbe  
performed. The device is shipped from Catalyst with the  
softwareprotectionNOTENABLED(theCAT28C64Bis  
in the standard operating mode).  
(2) A power on delay mechanism, tINIT (see AC  
characteristics), provides a 5 to 10 ms delay before  
a write sequence, after VCC has reached 3.5V min.  
(3) Write inhibit is activated by holding any one of OE  
low, CE high or WE high.

on power-up in addition to the hardware protection  
provided.  
To allow the user the ability to program the device with  
anEEPROMprogrammer(orfortestingpurposes)there  
is a software command sequence for deactivating the  
data protection. The six step algorithm (Figure 10) will  
reset the internal protection circuitry, and the device will  
return to standard operating mode (Figure 12 provides  
reset timing). After the sixth byte of this reset sequence  
has been issued, standard byte or page writing can  
commence.
