The Start bit is detected by the device if CS and DI are both high with respect to the positive edge of CLK for Block Diagram the first time. Before a Start condition is detected, CS, CLK and DI VCC VSS may change in any combination (except to that of a Start condition), without resulting in any device Memory Address operation (Read, Write, Erase, EWEN, EWDS, ERAL Array Decoder or WRAL). As soon as CS is high, the device is no longer in Standby mode.

Clocking of the CLK pin is not necessary after the device has entered the WRAL cycle. The WRAL command does include an automatic ERAL cycle for the device. Therefore, the WRAL instruction does not require an ERAL instruc- tion, but the chip must be in the EWEN status.

If CS is low, the internal Data Out (DO) is used in the Read mode to output data control logic is held in a Reset status. synchronously with the CLK input (TPD after the positive edge of CLK). 3.2 Serial Clock (CLK) This pin also provides Ready/Busy status information The Serial Clock is used to synchronize the communi- during erase and write cycles. Ready/Busy status infor- cation between a master device and the 93XX series mation is available on the DO pin if CS is brought high device. Opcodes, address and data bits are clocked in after being low for minimum Chip Select low time (TCSL) on the positive edge of CLK. Data bits are also clocked and an erase or write operation has been initiated. out on the positive edge of CLK.

In this case, sequence (at high or low level) and can be continued DO is in the High-Z mode. If status is checked after the anytime with respect to clock high time (TCKH) and erase/write cycle, the data line will be high to indicate clock low time (TCKL).

For proper operation, ORG of clock cycles (respectively low-to-high transitions of must be tied to a valid logic level. CLK) must be provided. These clock cycles are required to clock in all required opcode, address and 93XX46A devices are always (x8) organization and 93XX46B devices are always (x16) organization.

Note the following details of the code protection feature on Microchip devices: • Microchip products meet the specification contained in their particular Microchip Data Sheet. • Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the intended manner and under normal conditions. • There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data Sheets. Most likely, the person doing so is engaged in theft of intellectual property. • Microchip is willing to work with the customer who is concerned about the integrity of their code. • Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not mean that we are guaranteeing the product as “unbreakable.” Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act.
