DESCRIPTION
using a two write cycle scheme. Address and Data are
latched to free the I/O bus and address bus during the
write operation.
TheCAT28F010isahighspeed128Kx8-bitelectrically
erasable and reprogrammable Flash memory ideally
suited for applications requiring in-system or after-sale
code updates. Electrical erasure of the full memory
contents is achieved typically within 0.5 second.
The CAT28F010 is manufactured using Catalyst’s
advancedCMOSfloatinggatetechnology. Itisdesigned
to endure 100,000 program/erase cycles and has a data
retention of 10 years. The device is available in JEDEC
approved 32-pin plastic DIP, 32-pin PLCC or 32-pin
TSOP packages.
It is pin and Read timing compatible with standard
EPROM and EEPROM devices. Programming and
Erase are performed through an operation and verify
algorithm. The instructions are input via the I/O bus,

Note:
(1) Please refer to Supply characteristics for the value of VPPH and VPPL. The VPP supply can be either hardwired or switched. If VPP is
switched, VPPL can be ground, less than VCC + 2.0V or a no connect with a resistor tied to ground.
(2) Program and Erase operations are controlled by internal stop timers.
(3) ‘Typicals’ are not guaranteed, but based on characterization data. Data taken at 25°C, 12.0V VPP
.
(4) Minimum byte programming time (excluding system overhead) is 16 µs (10 µs program + 6 µs write recovery), while maximum is 400 µs/
byte (16 µs x 25 loops). Max chip programming time is specified lower than the worst case allowed by the programming algorithm since
most bytes program significantly faster than the worst case byte.
(5) Excludes 00H Programming prior to Erasure.

CAT28F010
READ OPERATIONS
Read Mode
The conventional mode is entered as a regular READ
mode by driving the CE and OE pins low (with WE high),
andapplyingtherequiredhighvoltageonaddresspinA9
while all other address lines are held at VIL.
A Read operation is performed with both CE and OE low
and with WE high. VPP can be either high or low,
however, if VPP is high, the Set READ command has to
be sent before reading data (see Write Operations). The
data retrieved from the I/O pins reflects the contents of
thememorylocationcorrespondingtothestateofthe17
address pins. The respective timing waveforms for the
read operation are shown in Figure 3. Refer to the AC
Read characteristics for specific timing parameters.
A Read cycle from address 0000H retrieves the binary
code for the IC manufacturer on outputs I/O0 to I/O7:
CATALYST Code = 00110001 (31H)
A Read cycle from address 0001H retrieves the binary
code for the device on outputs I/O0 to I/O7.
Signature Mode
The signature mode allows the user to identify the IC
manufacturer and the type of device while the device
residesinthetargetsystem. Thismodecanbeactivated
in either of two ways; through the conventional method
of applying a high voltage (12V) to address pin A9 or by
sending an instruction to the command register (see
Write Operations).
28F010 Code = 1011 0100 (B4H)
Standby Mode
With CE at a logic-high level, the CAT28F010 is placed
in a standby mode where most of the device circuitry is
disabled, thereby substantially reducing power con-
sumption. The outputs are placed in a high-impedance
state.

Signature Mode
WRITE OPERATIONS
An alternative method for reading device signature (see
Read Operations Signature Mode), is initiated by writing
the code 90H into the command register while keeping
VPP high. A read cycle from address 0000H with CE and
OE low (and WE high) will output the device signature.
The following operations are initiated by observing the
sequence specified in the Write Command Table.
Read Mode
The device can be put into a standard READ mode by
initiating a write cycle with 00H on the data bus. The
subsequent read cycles will be performed similar to a
standard EPROM or E2PROM Read.
CATALYST Code = 00110001 (31H)
A Read cycle from address 0001H retrieves the binary
code for the device on outputs I/O0 to I/O7.
28F010 Code = 1011 0100 (B4H)

Erase Mode
Erase-Verify Mode
During the first Write cycle, the command 20H is written
into the command register. In order to commence the
eraseoperation, theidenticalcommandof20Hhastobe
written again into the register. This two-step process
ensures against accidental erasure of the memory con-
tents. The final erase cycle will be stopped at the rising
edge of WE, at which time the Erase Verify command
(A0H)issenttothecommandregister. Duringthiscycle,
the address to be verified is sent to the address bus and
latched when WE goes low. An integrated stop timer
allows for automatic timing control over this operation,
eliminating the need for a maximum erase timing speci-
fication. Refer to AC Characteristics (Program/Erase)
for specific timing parameters.
The Erase-verify operation is performed on every byte
after each erase pulse to verify that the bits have been
erased.
Programming Mode
The programming operation is initiated using the pro-
gramming algorithm of Figure 7. During the first write
cycle, the command 40H is written into the command
register. During the second write cycle, the address of
thememorylocationtobeprogrammedislatchedonthe
falling edge of WE, while the data is latched on the rising
edge of WE. The program operation terminates with the
next rising edge of WE. An integrated stop timer allows
forautomatictimingcontroloverthisoperation, eliminat-
ing the need for a maximum program timing specifica-
tion. Refer to AC Characteristics (Program/Erase) for
specific timing parameters.

CAT28F010
Program-Verify Mode
POWER UP/DOWN PROTECTION
A Program-verify cycle is performed to ensure that all
bits have been correctly programmed following each
byte programming operation. The specific address is
already latched from the write cycle just completed, and
stayslatcheduntiltheverifyiscompleted. TheProgram-
verify operation is initiated by writing C0H into the
command register. An internal reference generates the
necessary high voltages so that the user does not need
to modify VCC. Refer to AC Characteristics (Program/
Erase) for specific timing parameters.
The CAT28F010 offers protection against inadvertent
programming during VPP and VCC power transitions.
When powering up the device there is no power-on
sequencing necessary. In other words, VPP and VCC
may power up in any order. Additionally VPP may be
hardwired to VPPH independent of the state of VCC and
any power up/down cycling. The internal command
register of the CAT28F010 is reset to the Read Mode on
power up.
Abort/Reset
POWER SUPPLY DECOUPLING
An Abort/Reset command is available to allow the user
to safely abort an erase or program sequence. Two
consecutive program cycles with FFH on the data bus
will abort an erase or a program operation. The abort/
reset operation can interrupt at any time in a program or
erase operation and the device is reset to the Read
Mode.
To reduce the effect of transient power supply voltage
spikes, it is good practice to use a 0.1µF ceramic
capacitorbetweenVCC andVSS andVPP andVSS.These
high-frequency capacitors should be placed as close as
possible to the device for optimum decoupling.
