Valid only at VД®RASE:В The ERASE instruction programs all bits in the specified memory location to the Logic 1 state. Write Enable must precede all programming modes.Д®rases all memory locations. Reads data stored in memory at specified address. Note:В Once in the EWEN state, programming remains enabled until an EWDS instruction is executed, or V An Erase/Write Enable (EWEN) instruction must be executed first before any programming instructions can be carried out. In this case, the dummy bit (Logic 0) will not be clocked out between memory locations, thus allowing for a continuous stream of data to be read.Д®rase/Write Enable (EWEN):В To ensure data integrity, the part automatically goes into the Erase/Write Disable (EWDS) state when power is first applied.

The device will automatically increment the internal address pointer and clock out the next memory location as long as Chip Select (CS) is held high. The AT93C56B/66B supports sequential Read operations. It should be noted that a dummy bit (Logic 0) precedes the 8-bit or 16-bit data output string.

Output data changes are synchronized with the rising edges of the Serial Clock pin, SK. After the instruction and address are decoded, data from the selected memory location is available at the Serial Output pin, DO.

READ:В The READ instruction contains the address code for the memory location to be read. The Xs in the address field represent donвЂ™t care values, and must be clocked. A valid instruction starts with a rising edge of CS and consists of a Start bit (Logic 1), followed by the appropriate opcode, and the desired memory address location. Device operation is controlled by seven instructions issued by the Host processor. The AT93C56B/66B is accessed via a simple and versatile 3-wire serial communication interface. = as specified, CL = 1 TTL gate and 100pF Max are reference only, and are not tested.ДЄpplicable over recommended operating range from T This parameter is characterized, and is not 100% tested. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. This is a stress rating only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this specification is not implied. Maximum RatingsвЂ Вќ may cause permanent damage to the device. *Notice:В Stresses beyond those listed under вЂ Е“Absolute Maximum Operating VoltageВ .В 6.25VДC Output CurrentВ .5.0mA Voltage on any pin with respect to ground When CS is brought high following the initiation of a write cycle, the DO pin outputs the Ready/Busy status of the part. The write cycle is only enabled when the part is in the Erase/Write Enable state. The write cycle is completely self-timed, and no separate erase cycle is required before Write. Upon receiving a Read instruction at DI, the address is decoded, and the data is clocked out serially on the DO pin. The AT93C56B/66B is enabled through the Chip Select pin (CS) and accessed via a 3-wire serial interface consisting of Data Input (DI), Data Output (DO), and Shift Clock (SK). The AT93C56B/66B is available in space-saving 8-lead JEDEC SOIC, 8-lead TSSOP, 8-pad UDFN, 8-pad XDFN, and 8-ball VFBGA packages.
