93LC66B-I/P Datasheet

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.

This falling edge of the CS pin initiates the self-timed programming cycle.

This gives datzsheet 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.

No licenses are conveyed, implicitly or otherwise, under any intellectual property rights. During power-up, all programming modes of operation are inhibited until VCC has reached a level greater than 2.

A high level selects the device; a low level deselects the device and forces it into standby mode. Sequential read is possible when CS is held high.

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.

Exposure to maximum rating conditions for extended periods may affect device reliability. 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. This application is not tested but guaranteed by characterization.

Advanced CMOS technology makes these devices ideal for low power nonvolatile memory applications. However, a programming cycle which is already in progress will be completed, regardless of the Chip Select CS input signal. No 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.


As soon as CS is high, the device is no longer in the standby mode.

93LC66B – Memory – Memory

CS is brought low following the loading of the last address bit. Opcode, address, and data bits are clocked in on the positive edge of CLK. After execution of an instruction i.

The memory data will automatically cycle to the next register and output sequentially. After the last data bit is put on the DI pin, the falling edge of 93l66b initiates the self-timed autoerase and programming cycle. 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.

If CS is brought low during a program cycle, the device will go into standby mode as soon as the programming cycle is completed. During power-down, the source data protection circuitry acts to inhibit all programming modes when Vcc has fallen below 2. After power-up, the device is automatically in the EWDS mode.
