CAT93C66, CAT93W66
Device Operation
The CAT93C66 is a 4096 ? bit nonvolatile memory
intended for use with industry standard microprocessors.
The CAT93C66 can be organized as either registers of 16
bits or 8 bits. When organized as X16, seven 11 ? bit
instructions control the reading, writing and erase
operations of the device. When organized as X8, seven
12 ? bit instructions control the reading, writing and erase
operations of the device. The CAT93W66 works in x16
mode only. The device operates on a single power supply
and will generate on chip, the high voltage required during
any write operation.
Instructions, addresses, and write data are clocked into the
DI pin on the rising edge of the clock (SK). The DO pin is
normally in a high impedance state except when reading data
from the device, or when checking the ready/busy status
after a write operation. The serial communication protocol
follows the timing shown in Figure 2.
Table 11. INSTRUCTION SET
Address
The ready/busy status can be determined after the start of
internal write cycle by selecting the device (CS high) and
polling the DO pin; DO low indicates that the write
operation is not completed, while DO high indicates that the
device is ready for the next instruction. If necessary, the DO
pin may be placed back into a high impedance state during
chip select by shifting a dummy “1” into the DI pin. The DO
pin will enter the high impedance state on the rising edge of
the clock (SK). Placing the DO pin into the high impedance
state is recommended in applications where the DI pin and
the DO pin are to be tied together to form a common DI/O
pin.
The format for all instructions sent to the device is a
logical “1” start bit, a 2 ? bit (or 4 ? bit) opcode, 8 ? bit address
(an additional bit when organized X8) and for write
operations a 16 ? bit data field (8 ? bit for X8 organizations).
The instruction format is shown in Instruction Set table.
