It may also interface with microcontrollers that do not have a built-in Synchronous Serial Port by using discrete I/O lines programmed properly with the software. The 25XX080C/D 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 and the HOLD pin must be high for the entire operation. Table 2-1 contains a list of the possible instruction bytes and format for device operation. All instructions, addresses, and data are transferred MSB first, LSB last. Data (SI) is sampled on the first rising edge of SCK after CS goes low. If the clock line is shared with other peripheral devices on the SPI bus, the user can assert the HOLD input and place the 25XX080C/D in ‘HOLD’ mode. After releasing the HOLD pin, operation will resume from the point when the HOLD was asserted. 2.2 Read Sequence The device is selected by pulling CS low. The 8-bit READ instruction is transmitted to the 25XX080C/D followed by the 16-bit address, with the six MSBs of the address being “don’t care” bits. 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 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 (03FFh), the address counter rolls over to address 0000h allowing the read cycle to be continued indefinitely. The read operation is terminated by raising the CS pin (Figure 2-1). DS22151A-page 6 2.3 Write Sequence Prior to any attempt to write data to the 25XX080C/D, the write enable latch must be set by issuing the WREN instruction (Figure 2-4). This is done by setting CS low and then clocking out the proper instruction into the 25XX080C/D. After all eight bits of the instruction are transmitted, the CS must be brought high to set the write enable latch. 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. Once the write enable latch is set, the user may proceed by setting the CS low, issuing a WRITE instruction, followed by the 16-bit address, with the six MSBs of the address being “don’t care” bits, and then the data to be written. Up to 16 bytes (25XX080C) or 32 bytes (25XX080D) of data can be sent to the device before a write cycle is necessary. The only restriction is that all of the bytes must reside in the same page. Note: Page write operations are limited to writing bytes within a single physical page, regardless of the number of bytes actually being written. Physical page boundaries start at addresses that are integer multiples of the page buffer size (or ‘page size’) and, end at addresses that are integer multiples of page size – 1. If a Page Write command attempts to write across a physical page boundary, the result is that the data wraps around to the beginning of the current page (overwriting data previously stored there), instead of being written to the next page as might be expected. It is therefore necessary for the application software to prevent page write operations that would attempt to cross a page boundary. For the data to be actually written to the array, the CS must be brought high after the Least Significant bit (D0) of the nth data byte has been clocked in. If CS is brought high at any other time, the write operation will not be completed. Refer to Figure 2-2 and Figure 2-3 for more detailed illustrations on the byte write sequence and the page write sequence, respectively. While the write is in progress, the STATUS register may be read to check the status of the WPEN, WIP, WEL, BP1 and BP0 bits (Figure 2-6). A read attempt of a memory array location will not be possible during a write cycle. When the write cycle is completed, the write enable latch is reset. © 2009 Microchip Technology Inc. 25XX080C/D Block Diagram STATUS Register I/O Control Logic HV Generator Memory Control Logic EEPROM Array X Dec Page Latches SI SO Y Decoder CS SCK Sense Amp.

See Table 2-4 for the Write-Protect Functionality Matrix. This latch must be set before any write operation will be completed internally. The WREN instruction will set the latch, and the WRDI will reset the latch.

DS22151A-page 9 25XX080C/D 2.5 Read Status Register (RDSR) Instruction The Write Enable Latch (WEL) bit indicates the status of the write enable latch and is read only. When set to a ‘1’, the latch allows writes to the array or the STATUS register, when set to a ‘0’, the latch prohibits writes to the array or the STATUS register. The state of this bit can always be updated via the WREN or WRDI commands regardless of the state of write protection on the STATUS register. These commands are shown in Figure 2-4 and Figure 2-5. The Read Status Register (RDSR) instruction provides access to the STATUS register. The STATUS register may be read at any time, even during a write cycle. The STATUS register is formatted as follows: TABLE 2-2: STATUS REGISTER 7 6 5 4 3 2 1 W/R – – – W/R W/R R WPEN X X X BP1 BP0 WEL W/R = writable/readable. R = read-only. The Block Protection (BP0 and BP1) bits indicate which blocks are currently write-protected. These bits are set by the user issuing the WRSR instruction, which is in Figure 2-7. These bits are nonvolatile and are shown in Table 2-3. 0 R WIP The Write-In-Process (WIP) bit indicates whether the 25XX080C/D is busy with a write operation. When set to a ‘1’, a write is in progress, when set to a ‘0’, no write is in progress. This bit is read-only. FIGURE 2-6: See Figure 2-6 for the RDSR timing sequence.

TABLE 2-3: The Write Status Register (WRSR) instruction allows the user to write to the nonvolatile bits in the STATUS register as shown in Table 2-2. The user is able to select one of four levels of protection for the array by writing to the appropriate bits in the STATUS register. The array is divided up into four segments. The user has the ability to write-protect none, one, two or all four of the segments of the array. The partitioning is controlled as shown in Table 2-3. The Write-Protect Enable (WPEN) bit is also a nonvolatile bit that is available as an enable bit for the WP pin. The Write-Protect (WP) pin and the Write-Protect Enable (WPEN) bit in the STATUS register control the programmable hardware write-protect feature. Hardware write protection is enabled when WP pin is low and the WPEN bit is high. Hardware write protection is disabled when either the WP pin is high or the WPEN bit is low. When the chip is hardware write-protected, only writes to nonvolatile bits in the STATUS register are disabled. See Table 2-4 for a matrix of functionality on the WPEN bit.

The WP pin functions will be enabled when the WPEN bit is set high. TABLE 3-1: 3.4 PIN FUNCTION TABLE Name Pin Number CS 1 Function Chip Select Input 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. SO 2 Serial Data Output WP 3 Write-Protect Pin 3.5 VSS 4 Ground SI 5 Serial Data Input The SCK is used to synchronize the communication between a master and the 25XX080C/D. 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. SCK 6 Serial Clock Input HOLD 7 Hold Input VCC 8 Supply Voltage 3.6 3.1 Chip Select (CS) A low level on this pin selects the device. A high level deselects the device and forces it into Standby mode. However, a programming cycle which is already initiated or in progress will be completed, regardless of the CS input signal. If CS is brought high during a program cycle, the device will go into Standby mode as soon as the programming cycle is complete. When the device is deselected, SO goes to the high-impedance state, allowing multiple parts to share the same SPI bus. A low-to-high transition on CS after a valid write sequence initiates an internal write cycle. After powerup, a low level on CS is required prior to any sequence being initiated. 3.2 Serial Output (SO) The SO pin is used to transfer data out of the 25XX080C/D. During a read cycle, data is shifted out on this pin after the falling edge of the serial clock. 3.3 Serial Input (SI) Serial Clock (SCK) Hold (HOLD) The HOLD pin is used to suspend transmission to the 25XX080C/D while in the middle of a serial sequence without having to retransmit the entire sequence 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 must be brought low while SCK is low, otherwise the HOLD function will not be invoked until the next SCK high-tolow transition. The 25XX080C/D must remain selected during this sequence. The SI, SCK and SO pins are in a high-impedance state during the time the device is paused and transitions on these pins will be ignored. To resume serial communication, HOLD must be brought high while the SCK pin is low, otherwise serial communication will not resume. Lowering the HOLD line at any time will tri-state the SO line. Write-Protect (WP) This pin is used in conjunction with the WPEN bit in the STATUS register to prohibit writes to the nonvolatile bits in the STATUS register. When WP is low and WPEN is high, writing to the nonvolatile bits in the STATUS register is disabled. All other operations function normally. When WP is high, all functions, including writes to the nonvolatile bits in the STATUS register operate normally. If the WPEN bit is set, WP low during a STATUS register write sequence will disable writing to the STATUS register. If an internal write cycle has already begun, WP going low will have no effect on the write. The WP pin function is blocked when the WPEN bit in the STATUS register is low. This allows the user to install the 25XX080C/D in a system with WP pin © 2009 Microchip Technology Inc.

Note the following details of the code protection feature on Microchip devices: • Microchip products meet the specification contained in their particular Microchip Data Sheet. • Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the intended manner and under normal conditions. • There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data Sheets. Most likely, the person doing so is engaged in theft of intellectual property. • Microchip is willing to work with the customer who is concerned about the integrity of their code. • Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not mean that we are guaranteeing the product as “unbreakable.” Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our products.
