No licenses are conveyed, implicitly or otherwise, under any intellectual property rights. However, a programming cycle which is already in progress will be completed, regardless of the Chip Select CS input signal. Advanced CMOS technology makes these devices ideal for low power nonvolatile memory applications.
The higher the current sourcing capability of A0, the higher the voltage at the Data Out pin. Data bits are also clocked out on the positive edge of CLK.
If CS is brought low during a program cycle, the device will go into standby mode as soon as the programming cycle is completed. Your local Microchip sales ofce. Chandler, AZ Tel: All other trademarks mentioned herein are the property of their respective companies.

During power-down, the source data protection circuitry acts to inhibit all programming modes when Vcc has fallen below 2. Exposure to maximum rating conditions for extended periods may affect device reliability.
After power-up, the device is automatically in the EWDS mode. If CS is high, but a START condition has not been detected, any number of clock cycles can be received by the device without changing its status i.
This gives the controlling master freedom in preparing opcode, address, and data. CS is brought low following the loading of the last address bit.
The memory data will automatically cycle to the next register and output sequentially.

Sequential read is possible when CS is held high. As soon as CS is high, the device is no longer in the standby mode.
A high level selects the device; a low level deselects the device and forces it into standby mode.
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. Datasheeet falling edge of the CS pin initiates the self-timed programming cycle. After execution of an instruction i. 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contained in this publication regarding device applications and the like is intended for suggestion only and may be superseded by updates.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 application is not tested but guaranteed by characterization. During power-up, all programming modes of operation are inhibited until VCC has reached a level greater than 2. The Microchip logo and name are registered trademarks of Microchip Technology Inc.

These clock cycles are required to clock in all required opcode, address, and data bits before an eatasheet is executed Table and Table Under such a condition the voltage level seen at Data Out is undened and will depend upon the relative impedances of Data Out and the signal source driving A0.
After the last data bit is put on the DI pin, the falling edge of CS initiates the self-timed autoerase and programming datashest. Opcode, address, and data bits are clocked in 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 in.
