When the device is deselected, SO goes to the high- impedance state, allowing multiple parts to share the same SPI bus. After power-up, a low level on CS# is required, prior to any sequence being initiated. Serial Clock (SCK) The SCK is used to synchronize the communication between a master and Serial SRAM. Instructions, addresses or data present on the SI pin are latched on the rising edge of the clock input, while data on the SO pin is updated after the falling edge of the clock input. Serial Output (SO: SPI mode) The SO pin is used to transfer data out of the device. During a read cycle, data is shifted out on this pin after the falling edge of the serial clock. Serial Input (SI: SPI mode) The SI pin is used to transfer data into the device. It receives instructions, addresses, and data. Data is latched on the rising edge of the serial clock. HOLD Function (HOLD#: SPI Mode, and SDI Mode) The HOLD# pin is used to suspend transmission to Serial SRAM while in the middle of a serial sequence without having to re-transmit the entire sequence over again. It must be held high any time this function is not being used. Once the device is selected and a serial sequence is underway, the HOLD# pin may be pulled low to pause further serial communication without resetting the serial sequence. The HOLD# pin should be brought low while SCK is low, otherwise the HOLD function will not be invoked until the next SCK high-to-low transition. The device must remain selected during this sequence. The SI and SCK levels are “don’t cares” during the time the device is paused and any transitions on these pins will be ignored. To resume serial communication, HOLD# should be brought high while the SCK pin is low, otherwise serial communication will not be resumed until the next SCK high-to-low transition. The SO line will tri-state immediately upon a high-to low transition of the HOLD# pin, and will begin outputting again Immediately upon a subsequent low- to-high transition of the HOLD pin, independent of the state of SCK. Hold functionality is not available when operating in Quad SPI mode Serial Input / Output Pins (SIO0, SIO1: SDI Mode) The SIO0 and SIO1 pins are used for Dual SPI mode of operation (SI→SIO0, SO-->SIO1). Functionality of these I/O pins is shared with SO and SI. Serial Input / Output Pins (SIO0, SIO1, SIO2, SIO3: SQI Mode) The SIO0 through SIO3 pins are used for Quad SPI mode of operation. Because of the shared functionality of these pins the HOLD# feature is not available when using Quad SPI mode (Hold# →SIO3 in Quad SPI mode) DNU/SIO2 (Do Not Use or SIO2) Pin 3 is DNU (Do No Use) in SPI mode and SDI mode.

It can also interface with MultiIO SPI interface (Dual SPI and Quad SPI). The device contains an 8-bit instruction register. The device is accessed via the SI pin, with data being clocked in on the rising edge of SCK. The CS# pin must be low for the entire operation. All instructions, addresses and data are transferred MSB first, LSB last. OPERATION MODE The device has three modes of operation that are selected by setting bits 7 and 6 in the MODE register. The modes of operation are Byte, Page and Sequential. Byte Operation Byte Operation is selected when bits 7 and 6 in the MODE register are set to 00. In this mode, the read/ write operations are limited to only one byte. The Command followed by the 24-bit address is clocked into the device and the data to/from the device is transferred on the next eight clocks. Page Operation Page Operation is selected when bits 7 and 6 in the MODE register are set to 10. The device has 4096 pages of 32 bytes. In this mode, the read and write operations are limited to within the addressed page (the address is automatically incremented internally). If the data being read or written reaches the page boundary, then the internal address counter will increment to the start of the page. Sequential Operation Sequential Operation is selected when bits 7 and 6 in the MODE register are set to 01. Sequential operation allows the entire array to be written to and read from. The internal address counter is automatically incremented and page boundaries are ignored. When the internal address counter reaches the end of the array, the address counter will roll over to 0x00000. . WRITE MODE Prior to any attempt to write data to the device, the device must be selected by bringing CS# low. Once the device is selected, the Write command can be started by issuing a WRITE instruction, followed by the 24-bit address, with the first seven MSB’s of the address being a “don’t care” bit, and then the data to be written. A write is terminated by the CS# being brought high. If operating in Page mode, after the initial data byte is shifted in, additional bytes can be shifted into the device. The Address Pointer is automatically incremented. This operation can continue for the entire page (32 bytes) before data will start to be overwritten. If operating in Sequential mode, after the initial data byte is shifted in, additional bytes can be clocked into the Device. The internal Address Pointer is automatically incremented. When the Address Pointer reaches the highest Address (1FFFFh), the address counter rolls over to (00000h). This allows the operation to continue indefinitely. However previous data will be overwritten. READ MODE The device is selected by pulling CS# Low. Then 8 bit instruction is transmitted to the device followed by the 24 bit address, with the first seven MSB’s of the address being a “don’t care” bit. After the correct READ instruction and address are sent, the data stored in the memory at the selected address is shifted out on the SO pin. If operating in Sequential mode, the data stored in the memory at the next address can be read sequentially by continuing to provide clock pulses. The internal Address Pointer is automatically incremented to the next higher address after each byte of data is shifted out. When the highest address is reached (1FFFFh), the address counter rolls over to address 00000h, allowing the read cycle to be continued indefinitely. The read operation is terminated by raising the CS# pin. Integrated Silicon Solution, Inc.- www.issi.com Rev.
