The Serial Flash is organized as 16 sectors of 4096 Bytes for SST45VF512, 32 sectors of 4096 Bytes for the SST45VF010 and 64 sectors of 4096 Bytes for the SST45VF020. The memory is accessed for Read or Erase/Program by the SPI bus compatible serial protocol. The bus signals are: serial data input (SI), serial data output (SO), serial clock (SCK), write protect (WP#), chip enable (CE#), and hardware reset (RESET#). The SST45VFxxx devices are offered in 8-pin SOIC package. See Figure 1 for the pinout. Device Operation The SST45VFxxx uses bus cycles of 8 bits each for commands, data, and addresses to execute operations. The operation instructions are listed in Table 2. All instructions are synchronized off a high to low transi- tion of CE#. The first low to high transition on SCK will initiate the instruction sequence. Inputs will be accepted on the rising edge of SCK starting with the most signifi- cant bit. Any low to high transition on CE# before the input instruction completes will terminate any instruction in progress and return the device to the standby mode. Read The Read operation outputs the data in order from the initial accessed address. While SCK is input, the address will be incremented automatically until end (top) of the address space, then the internal address pointer auto- matically increments to beginning (bottom) of the ad- dress space (00000H), and data out stream will continue. The read data stream is continuous through all ad- dresses until terminated by a low to high transition on CE#. Sector/Chip-Erase Operation The Sector-Erase operation clears all bits in the selected sector to “FF”. The Chip-Erase instruction clears all bits in the device to “FF”. Byte-Program Operation The Byte-Program operation programs the bits in the selected byte to the desired data. The selected byte must be in the erased state (“FF”) when initiating a Program operation. The data is input from bit 7 to bit 0 in order. Software Status Operation The Status operation determines if an Erase or Program operation is in progress. If bit 0 is at a “0” an Erase or Program operation is in progress, the device is busy. If bit 0 is at a “1” the device is ready for any valid operation. The status read is continuous with ongoing clock cycles until terminated by a low to high transition on CE#. |
