... ERASE cycle is required before WRITE. The WRITE cycle is only enabled when the part is in the ERASE/WRITE ENABLE state. When CS is brought “high” following the initiation of a WRITE cycle, the DO pin outputs the READY/BUSY status of the part. The AT93C46B is available in 4.5V to 5.5V, 2.7V to 5.5V, and 2.5V to 5.5V versions. Pin Configuration Pin Name Function ...

... Functional Description The AT93C46B is accessed via a simple and versatile three-wire serial communication interface. Device opera- tion is controlled by seven instructions issued by the host processor. A valid instruction starts with a rising edge of CS and consists of a Start Bit (logic ‘1’) followed by the appro- priate Op Code and the desired memory Address location ...
