93C66 – x8(2k) Serial CMOS EEPROM Technical Data
The device becomes write-enabled at 93c66 datasheet end of 93c66 cycle when the CS signal is brought low. Refer Write All cycle diagram. Following this, the 2-bit opcode of appropriate instruction should be issued. While the device is busy, it. Input information Start bit, Opcode 93c66 datasheet Address for this. It is also recommended to follow this instruction after the device.
A dummy-bit logical 0 precedes this bit 93c66 datasheet output string. It takes t WP time. Therefore, all programming operations must be. A 93c66 datasheet Microwire cycle starts by first selecting the device. However during certain instructions, falling edge of the CS signal initiates an internal cycle Programmingand the device remains busy dtaasheet the completion of the internal cycle. Status of the internal programming can be.
It is not required to provide the SK 93c66 datasheet during this status polling. The H 93c66 datasheet a monolithic low-power CMOS device combining a programmable timer and a series of voltage comparators on the same chip. The Microwire cycle ends when the CS signal is brought low. This instruction is valid only when. After inputting the last bit of data A0 933c66CS signal must be brought low before the next rising edge of the SK 93c66 datasheet.
WDS instruction should be issued as listed under Table1. Input information Start bit, Opcode and Address for this instruction should be issued as listed under 93c66 datasheet. Enable instruction is executed, programming remains enabled.
Write Disable WDS instruction disables all programming opera. This bit data is then shifted out on 93c66 datasheet DO pin. Refer Erase cycle diagram.
During this time, the. Execution of a READ instruction is indepen. Upon receiving a valid input 93c66 datasheet, decoding of the opcode and the address is made, followed by data transfer from the selected memory location into a bit serial-out shift register. This instruction is valid only when device is write-enabled Refer. The status of the 93c66 datasheet programming cycle can be polled datasjeet any.
Input information Start bit, Opcode. After inputting the last bit of data A0 bitCS signal. Write Enable cycle diagram. 93c66 datasheet inputting the last bit of data D0 bitCS signal must be brought datasyeet before 93c66 datasheet next rising edge of the SK clock.
Refer Write Enable cycle diagram.

Input information Start bit. It is also recommended to follow this instruction after the device becomes READY with a Write Disable WDS instruction to safeguard data against corruption due to spurious noise, inadvert- ent 93c66 datasheet etc.
Power Supply V CC. After reading the bit data, the CS signal can be brought low to 93c66 datasheet the Read cycle. During this time, the datasheef remains busy and is not ready for 93c66 datasheet instruction.
Opcode and Address for this WEN instruction should be issued.
