If CS is brought low during a program cycle, the device will go into standby mode as soon as the programming cycle is completed. 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. M Preliminary Information contained in this publication regarding device applications and the like is daatsheet for suggestion only and may be superseded by updates.
The memory data 93lc6b automatically cycle to the next register and output sequentially.
CS is brought low following the loading of the last address bit. After the last data bit is put on the DI pin, the ratasheet edge of CS initiates the self-timed autoerase and programming cycle. After execution of an instruction i.
93lc6b clock cycles are required to clock in all required opcode, address, and data bits before an instruction is executed Table and Table An instruction following a START condition will only be executed datassheet the required amount of opcodes, addresses, and data bits for any particular instruction is clocked in. Exposure to maximum rating conditions for extended periods may affect device reliability. Sequential read is possible when CS is held high.
This falling edge of the CS pin initiates the self-timed programming cycle.
Opcode, address, and vatasheet bits are clocked in on the positive edge of CLK. Chandler, AZ Tel: A high level selects the device; a low level deselects the device and forces it into standby mode. Data bits are also clocked out on the positive edge of CLK.

During power-up, all programming modes of operation are inhibited until VCC has reached a level greater than 2. Under such a condition the voltage level seen at Data Out is undened and will depend upon the relative impedances of Data Out and 93llc66b signal source driving A0.

However, a programming cycle which is already in progress will be completed, regardless of the Chip Select CS input signal. Advanced CMOS dagasheet makes these devices ideal for low power nonvolatile memory applications. The higher 9l3c66b current sourcing capability of A0, the higher the voltage at the Data Out pin.

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. During power-down, the source data protection circuitry acts to inhibit all programming modes when Vcc has fallen below 2.
