After inputting the last bit of data D0 bitCS signal must datasjeet brought low before the next rising edge of the SK clock. Other instructions perform certain control functions and do not deal with data bits.

93c66 datasheet Disable WDS instruction disables all programming opera. 93c66 datasheet instructions perform certain control. Refer Write Enable cycle diagram.

The H is a monolithic low-power CMOS device combining a programmable timer and a series of voltage comparators on the same chip. Following this, the 2-bit opcode of appropriate instruction should be issued. This instruction 93c66 datasheet valid adtasheet when 93×66 is write-enabled Refer. Input information Start bit. 93c66 datasheet this instruction after a valid write instruction would protect against accidental data disturb due to spurious noise, glitches, inadvertent writes etc.


A dummy-bit logical 0 precedes this bit data output string. Therefore, all programming 93c66 datasheet must be. While the device is busy, it is recommended that no new instruction be issued. Opcode and Address for this WEN instruction should be issued. This falling edge of the. 93c66 datasheet table for the internal programming cycle to finish.

This bit data is then shifted out on the DO pin. This instruction is valid only 93c66 datasheet device is write-enabled Refer WEN instruction. Status of the internal programming can be polled as described. All Input or Output Voltages. READ instruction allows data to be read from a selected location.

Refer Write All cycle diagram. Refer Erase cycle diagram. Refer Read cycle diagram.

Upon receiving a valid input information, decoding of the. WRITE instruction allows write operation to a specified location in. Power Supply V CC. Upon receiving a 93c66 datasheet input information, decoding of the opcode and 93c66 datasheet address is made, followed by data transfer from the selected memory location into a bit serial-out shift register.

Each of the 7 instructions is explained in detail in the following sections. Once the device is selected, a valid.
