The synchronous Serial Peripheral Interface (SPI) helps the CAT25010/20/40 to interface directly with many of today’s popular microcontrollers. The CAT25010/20/40 contains an 8-bit instruction register. (The instruction set and the operation codes are detailed in the instruction set table) After the device is selected with CS going low, the first byte will be received. The part is accessed via the SI pin, with data being clocked in on the rising edge of SCK. The first byte contains one of the six op-codes that define the operation to be performed. PIN DESCRIPTION SI: Serial Input SI is the serial data input pin. This pin is used to input all opcodes, byte addresses, and data to be written to the CAT25010/20/40. Input data is latched on the rising edge of the serial clock for SPI modes (0, 0 & 1, 1). SO: Serial Output SO is the serial data output pin. This pin is used to transfer data out of the CAT25010/20/40. During a read cycle, data is shifted out on the falling edge of the serial clock for SPI modes (0,0 & 1,1). Figure 1.

Characteristics subject to change without notice CAT25010, CAT25020, CAT25040 WP: Write Protect WP is the Write Protect pin. The Write Protect pin will allow normal read/write operations when held high. When WP is tied low all write operations are inhibited. WP held low while CS is low will interrupt a write to the CAT25010/20/40. If the internal write cycle has already been initiated, WP going low will have no effect on any write operation. Figure 10 illustrates the WP timing sequence during a write operation. HOLD: Hold The HOLD pin is used to pause transmission to the CAT25010/20/40 while in the middle of a serial sequence without having to re-transmit entire sequence at a later time. To pause, HOLD must be brought low while SCK is low. The SO pin is in a high impedance state during the time the part is paused, and transitions on the SI pins will be ignored. To resume communication, HOLD is brought high, while SCK is low. (HOLD should be held high any time this function is not being used.) HOLD may be tied high directly to VCC or tied to VCC through a resistor. Figure 9 illustrates hold timing sequence. SCK: Serial Clock SCK is the serial clock pin. This pin is used to synchronize the communication between the microcontroller and the CAT25010/20/40. Opcodes, byte addresses, or data present on the SI pin are latched on the rising edge of the SCK. Data on the SO pin is updated on the falling edge of the SCK for SPI modes (0,0 & 1,1) . CS: Chip Select CS is the Chip select pin. CS low enables the CAT25010/ 20/40 and CS high disables the CAT25010/20/40. CS high takes the SO output pin to high impedance and forces the devices into a Standby Mode (unless an internal write operation is underway). A high to low transition on CS is required prior to any sequence being initiated. A low to high transition on CS after a valid write sequence is what initiates an internal write cycle.

Characteristics subject to change without notice 5 Doc. No. 1006, Rev. S CAT25010, CAT25020, CAT25040 STATUS REGISTER The Status Register indicates the status of the device. The RDY (Ready) bit indicates whether the CAT25010/ 20/40 is busy with a write operation. When set to 1 a write cycle is in progress and when set to 0 the device indicates it is ready. This bit is read only. The WEL (Write Enable) bit indicates the status of the write enable latch. When set to 1, the device is in a Write Enable state and when set to 0 the device is in a Write Disable state. The WEL bit can only be set by the WREN instruction and can be reset by the WRDI instruction. The BP0 and BP1 (Block Protect) bits indicate which blocks are currently protected. These bits are set by the user issuing the WRSR instruction. The user is allowed to protect quarter of the memory, half of the memory or the entire memory by setting these bits. Once protected, the user may only read from the protected portion of the array. These bits are non-volatile. DEVICE OPERATION Write Enable and Disable The CAT25010/20/40 contains a write enable latch. This latch must be set before any write operation. The device powers up in a write disable state when Vcc is applied. WREN instruction will enable writes (set the latch) to the device. If WP pin is held low, the write enable latch is reset to the write disabe state, regardless of the WREN Instruction. WRDI instruction will disable writes (reset the latch) to the device. Disabling writes will protect the device against inadvertent writes. READ Sequence The part is selected by pulling CS low. The 8-bit read instruction is transmitted to the CAT25010/20/40, followed by the 8-bit address for CAT25010/20/40 (for the 25040, bit 3 of the read data instruction contains address A8). 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. The data stored in the memory at the next address can be read sequentially by continuing Figure 2.

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, the address counter rolls over to 0000h allowing the read cycle to be continued indefinitely. The read operation is terminated by pulling the CS high. Read sequece is illustrated in Figure 4. To read the status register, RDSR instruction should be sent. The contents of the status register are shifted out on the SO line. The status register may be read at any time even during a write cycle. Reading status register is illustrated in Figure 5. WRITE Sequence The CAT25010/20/40 powers up in a Write Disable state. Prior to any write instructions, the WREN instruction must be sent to CAT25010/20/40. The device goes into Write enable state by pulling the CS low and then clocking the WREN instruction into CAT25010/20/40. The CS must be brought high after the WREN instruction to enable writes to the device. If the write operation is initiated immediately after the WREN instruction without CS being brought high, the data will not be written to the array because the write enable latch will not have been properly set. Also, for a successful write operation the Figure 4.

Byte Write Once the device is in a Write Enable state, the user may proceed with a write sequence by setting the CS low, issuing a write instruction via the SI line, followed by the 8-bit address for 25010/20/40 (for the 25040, bit 3 of the read data instruction contains address A8). Programming will start after the CS is brought high. Figure 6 illustrates byte write sequence. During an internal write cycle, all commands will be ignored except the RDSR (Read Status Register) instruction. The Status Register can be read to determine if the write cycle is still in progress. If Bit 0 of the Status Register is set at 1, write cycle is in progress. If Bit 0 is set at 0, the device is ready for the next instruction Page Write The CAT25010/20/40 features page write capability. After the initial byte, the host may continue to write up to 16 bytes of data to the CAT25010/20/40. After each byte of data received, lower order address bits are internally incremented by one; the high order bits of address will remain constant. The only restriction is that the X (X=16 for CAT25010/20/40) bytes must reside on the same page. If the address counter reaches the end of the page and clock continues, the counter will “roll over” to the first address of the page and overwrite any data that may have been written. The CAT25010/20/40 is automatically returned to the write disable state at the completion of the write cycle. Figure 8 illustrates the page write sequence. Status Register Write To write to the status register, the WRSR instruction should be sent. Only Bit 2 and Bit 3 of the status register can be written using the WRSR instruction. Figure 7 illustrates the sequence of writing to status register. Figure 6.

A WREN instruction must be issued to perform any writes to the device after power up. After power up, CS must be brought low to enter a ready state and receive an instruction. After a successful byte/page write or status register write, the CAT25010/20/40 goes into a write disable mode. CS must be set high after the proper number of clock cycles to start an internal write cycle. Access to the array during an internal write cycle is ignored and programming is continued. On power up, SO is in a high impedance. If an invalid opcode is received, no data will be shifted into the CAT25010/20/40, and the serial output pin (SO) will remain in a high impedance state until the falling edge of CS is detected again.
