EMBEDDED EEPROM OPERATION
The CAT130xx has a nonvolatile embedded memory
intended for use with industry standard micropro–
cessors. The memory can be organized as either
registers of 16 bits or 8 bits. The CAT130xx operates
on a single power supply and will generate on chip the
high voltage required during any write operation.
The format for all instructions sent to the device is a
logical “1” start bit, a 2-bit (or 4-bit) opcode, 6-bit
(13001) / 8-bit (13004) / 9-bit (13008) / 10-bit (13016)
address (an additional bit when organized as x8) and
for write operations a 16-bit data field (8-bit for x8
organization). The instruction format is shown in
Instruction Set Table.
