This adtasheet the controlling master freedom in preparing opcode, address, and data. 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. The higher the current sourcing capability of A0, the higher the voltage at the Data Out pin.

Advanced CMOS technology makes these devices ideal for low power nonvolatile memory applications. Sequential read is possible when CS is held high. Your local Microchip sales ofce. Data bits are also clocked out on the positive edge of CLK.

This falling edge of the CS pin initiates the self-timed programming cycle. CS is brought low following the loading of the last address bit.

A high level selects the device; a low level deselects the device and forces it into standby mode. During power-down, the source data protection circuitry acts to inhibit all programming modes when Vcc has fallen below 2.

After the last data bit is put on the DI pin, the falling edge of CS initiates the self-timed autoerase and programming cycle. After power-up, the device is automatically in the EWDS mode.

As soon as CS is high, the device is no longer in the standby mode. Dstasheet representation or warranty is given and no liability is assumed by Microchip Technology Incorporated with respect to the accuracy or use of such information, or infringement of patents or other intellectual property rights arising from such use or otherwise.

If CS is brought low during a program cycle, the device will go into standby mode as soon as the programming cycle is completed.

Exposure to dataseet rating conditions for extended periods may affect device reliability. The memory data will automatically cycle to the next register and output sequentially.

These clock cycles are required to clock in all required opcode, address, and data bits before an instruction is executed Table and Table However, a programming cycle which is already in progress will be completed, regardless of the Chip Select CS input signal.

Under such a condition datasheey voltage level seen at Data Out is undened and will depend upon the relative impedances of Data Out and the signal source driving A0.

During power-up, all programming modes of operation are inhibited datsaheet VCC has reached a level greater than 2. 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. An instruction following a START condition will only be executed if the datasheeg amount of opcodes, addresses, and data bits for any particular instruction is clocked in.
