G 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), and applying the required high voltage on address pin A9 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 the memory location corresponding to the state of the 17 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 resides in the target system. This mode can be activated 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 consumption. The outputs are placed in a high-impedance state. Figure 3. A.C.

Characteristics subject to change without notice CAT28F010 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) Figure 4. A.C.

Characteristics subject to change without notice CAT28F010 Erase Mode Erase-Verify Mode During the first Write cycle, the command 20H is written into the command register. In order to commence the erase operation, the identical command of 20H has to be written again into the register. This two-step process ensures against accidental erasure of the memory contents. The final erase cycle will be stopped at the rising edge of WE, at which time the Erase Verify command (A0H) is sent to the command register. During this cycle, 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 specification. 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 programming 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 the memory location to be programmed is latched on the 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 for automatic timing control over this operation, eliminating the need for a maximum program timing specification. Refer to AC Characteristics (Program/Erase) for specific timing parameters. Figure 6. A.C.

Characteristics subject to change without notice 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 stays latched until the verify is completed. The Programverify 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 capacitor between VCC and VSS and VPP and VSS. These high-frequency capacitors should be placed as close as possible to the device for optimum decoupling. Figure 8. Alternate A.C.
