... DESCRIPTION The Microchip Technology Inc. 93C56A 2K-bit, low-voltage serial Electrically Erasable PROM. The device memory is configured as 256 x 8 bits (93C56A) or 128 x 16 bits (93C56B). Advanced CMOS technol- ogy makes this device ideal for low-power, nonvolatile memory applications. The 93C56A/B is available in standard 8-pin DIP and surface mount SOIC packages ...

... RESET status. 2.2 Serial Clock (CLK) The Serial Clock is used to synchronize the communi- cation between a master device and the 93C56A/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 (93C56A) or 16-bit (93C56B) output string. The output data bits will toggle on the rising edge of the CLK and are stable after the specifi ...

... WRITE The WRITE instruction is followed by 8-bits (93C56A) 16-bits (93C56B) of data which are written into the specified address. After the last data bit is clocked into the DI pin, the self-timed auto-erase and programming cycle begins. The DO pin indicates the READY/BUSY status of the ...
