... GENERATOR DESCRIPTION The Microchip Technology Inc. 93LC66A/B are 4K-bit, low voltage serial Electrically Erasable PROMs. The device memory is configured as x8 (93LC66A) or x16 bits (93LC66B). Advanced CMOS technology makes these devices ideal for low power nonvolatile memory applications. The 93LC66A/B is available in standard 8-pin DIP, surface mount SOIC, and TSSOP packages ...

... RESET status. 2.2 Serial Clock (CLK) The Serial Clock (CLK) is used to synchronize the com- munication between a master device and the 93LC66A/ B. Opcode, address, and data bits are clocked in on the positive edge of CLK. Data bits are also clocked out on the positive edge of CLK. ...

... FUNCTIONAL DESCRIPTION Instructions, addresses, and write data are clocked into the DI pin on the rising edge of the clock (CLK). The DO pin is normally held in a HIGH-Z state except when reading data from the device, or when checking the READY/BUSY status during a programming operation. ...

... READ The READ instruction outputs the serial data of the addressed memory location on the DO pin. A dummy zero bit precedes the 8-bit (93LC66A) or 16-bit (93LC66B) output string. The output data bits will tog- gle on the rising edge of the CLK and are stable after the specified time delay (T sible when CS is held high ...

... WRITE The WRITE instruction is followed by 8 bits (93LC66A bits (93LC66B) of data which are written into the specified address. After the last data bit is put on the DI pin, the falling edge of CS initiates the self-timed auto- erase and programming cycle. The DO pin indicates the READY/BUSY status of the ...
