After power-up, the device is automatically in the EWDS mode.

The memory data will automatically cycle to the next register and output sequentially. Your local Microchip sales ofce. No licenses are conveyed, implicitly or otherwise, under any intellectual property rights.

Exposure to maximum rating conditions for extended periods may affect device reliability. Under such a condition the voltage level seen at Data Out is undened and will depend upon the relative impedances datwsheet Data Out and the signal source driving A0.

CS is brought low following the loading of the last address bit. Chandler, AZ Tel: All other trademarks mentioned herein are the property of their respective companies.

If CS is brought low during a program cycle, the datasgeet will go into standby mode as soon as the programming cycle is completed. The higher the current sourcing capability of A0, the higher the voltage at the Data Out pin.


This gives the controlling master freedom in preparing opcode, address, and data.

During power-down, the source data protection circuitry acts to inhibit all programming modes when Vcc has fallen below 2. Data bits are also clocked out on the positive edge of CLK. An instruction following a START condition will only be executed if the required amount of opcodes, addresses, and data bits for any particular instruction is clocked daasheet.

After the last data bit is put on the DI pin, the falling edge of CS initiates the self-timed autoerase and programming cycle.

If CS is high, but a START condition has not been detected, 93lc66n number of clock cycles can be received by the device without changing its status i. These clock cycles are required to clock in all required opcode, address, and data bits before an instruction is executed Table and Table During power-up, all programming modes of operation are inhibited until VCC has reached a level greater than 2. To determine if an errata sheet exists for a particular device, please contact one of the following: This is a stress rating only and functional operation of the device at those or any other conditions above those indicated in the operational listings of this specication is not implied.


Opcode, address, and data bits are clocked in on the positive edge of Datsheet.

M Preliminary Information contained in this publication regarding device applications and the like is intended for suggestion only and may be superseded by updates. This falling edge of the CS pin initiates the self-timed programming cycle.

However, a programming cycle which is already in progress will be completed, regardless of the Chip Select CS input signal. Sequential read is possible when CS is held high.

This application datasheeet not tested but guaranteed by characterization. A high level selects the device; a low level deselects the device and forces it into standby mode. After execution of an instruction i. As soon as CS is high, the device is no longer in the standby mode.
