The device is optimized for use in many industrial and commercial applications where low-power and low-voltage operation are essential. The AT25M01 is enabled through the Chip Select pin (CS) and accessed via a 3-wire interface consisting of Serial Data Input (SI), Serial Data Output (SO), and Serial Clock (SCK). All programming cycles are completely self-timed, and no separate Erase cycle is required before Write. Block Write protection is enabled by programming the status register with top ¼, top ½ or entire array of write protection. Separate Program Enable and Program Disable instructions are provided for additional data protection. Hardware data protection is provided via the WP pin to protect against inadvertent write attempts to the status register. The HOLD pin may be used to suspend any serial communication without resetting the serial sequence. Atmel-8824E-SEEPROM-AT25M01-Datasheet_052016 1. Pin Configurations Figure 1. 2.

Contact Atmel for further information. Serial Interface Description Master: The device that generates the serial clock. Slave: Because the Serial Clock pin (SCK) is always an input, the AT25M01 always operates as a slave. Transmitter/Receiver: The AT25M01 has separate pins designated for data transmission (SO) and reception (SI). MSB: The Most Significant Bit (MSB) is the first bit transmitted and received. Serial Opcode: After the device is selected with CS going low, the first byte will be received. This byte contains the opcode that defines the operations to be performed. Invalid Opcode: If an invalid opcode is received, no data will be shifted into the AT25M01, and the Serial Output pin (SO) will remain in a high-impedance state until the falling edge of CS is detected again. This will reinitialize the serial communication. Chip Select: The AT25M01 is selected when the CS pin is low. When the device is not selected, data will not be accepted via the SI pin, and the Serial Output pin (SO) will remain in a high impedance state. Hold: The HOLD pin is used in conjunction with the CS pin to select the AT25M01. When the device is selected and a serial sequence is underway, Hold can be used to pause the serial communication with the master device without resetting the serial sequence. To pause, the HOLD pin must be brought low while the SCK pin is low. To resume serial communication, the HOLD pin is brought high while the SCK pin is low (SCK may still toggle during HOLD). Inputs to the SI pin will be ignored while the SO pin is in the high impedance state. Write Protect: The Write Protect pin (WP) will allow normal read/write operations when held high. When the WP pin is brought low, and WPEN bit is one, all write operations to the status register are inhibited. WP going low while CS is still low will interrupt a write to the status register. If the internal write cycle has already been initiated, WP going low will have no effect on any write operation to the status register. The WP pin function is blocked when the WPEN bit in the status register is zero. This will allow the user to install the AT25M01 in a system with the WP pin tied to ground and still be able to write to the status register. All WP pin functions are enabled when the WPEN bit is set to one. 6 AT25M01 [DATASHEET] Atmel-8824E-SEEPROM-AT25M01-Datasheet_052016 Figure 5-1.

Functional Description The AT25M01 is designed to interface directly with the synchronous Serial Peripheral Interface (SPI) of the 6800 type series of microcontrollers. The AT25M01 utilizes an 8-bit instruction register. The list of instructions and their operation codes are contained in Table 6-1. All instructions, addresses, and data are transferred with the MSB first and start with a high-to-low CS transition. Table 6-1. Instruction Set for Atmel AT25M01 Instruction Name Instruction Format Operation WREN 0000 x110 Set Write Enable Latch WRDI 0000 x100 Reset Write Enable Latch RDSR 0000 x101 Read Status Register WRSR 0000 x001 Write Status Register READ 0000 x011 Read Data from Memory Array WRITE 0000 x010 Write Data to Memory Array Write Enable (WREN): The device will power-up in the write disable state when VCC is applied. All programming instructions must therefore be preceded by a Write Enable instruction. Write Disable (WRDI): To protect the device against inadvertent writes, the Write Disable instruction disables all programming modes. The WRDI instruction is independent of the status of the WP pin. Read Status Register (RDSR): The Read Status Register instruction provides access to the status register. The Ready/Busy and Write Enable status of the device can be determined by the RDSR instruction. Similarly, the Block Write Protection bits indicate the extent of protection employed. These bits are set by using the WRSR instruction. Table 6-2. Status Register Format Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0 WPEN X X X BP1 BP0 WEN RDY Table 6-3. Read Status Register Bit Detection Bit Definition Bit 0 (RDY) Bit 0 = 0 (RDY) indicates the device is ready. Bit 0 = 1 indicates the write cycle is in progress. Bit 1 (WEN) Bit 1 = 0 indicates the device is not write enabled. Bit 1 = 1 indicates the device is write enabled. Bit 2 (BP0) See Table 6-4 on page 9. Bit 3 (BP1) See Table 6-4 on page 9. Bits 4 6 are zeros when device is not in an internal write cycle. Bit 7 (WPEN) See Table 6-5 on page 9. Bits 0 7 are ones during an internal write cycle. 8 AT25M01 [DATASHEET] Atmel-8824E-SEEPROM-AT25M01-Datasheet_052016 Write Status Register (WRSR): The WRSR instruction allows the user to select one of four levels of protection. The AT25M01 is divided into four array segments. Top quarter (¼), top half (½), or all of the memory segments can be protected. Any of the data within any selected segment will therefore be read-only. The block write protection levels and corresponding status register control bits are shown in Table 6-4. The three bits, BP0, BP1, and WPEN are nonvolatile cells that have the same properties and functions as the regular memory cells (e.g. WREN, tWC, RDSR). Table 6-4. Block Write Protect Bits Status Register Bits Array Addresses Protected Level BP1 BP0 AT25M01 0 0 0 None 1(¼) 0 1 18000h – 1FFFFh 2(½) 1 0 10000h – 1FFFFh 3(All) 1 1 00000h – 1FFFFh The WRSR instruction also allows the user to enable or disable the Write Protect (WP) pin through the use of the Write Protect Enable (WPEN) bit. Hardware Write Protection is enabled when the WP pin is low and the WPEN bit is one. Hardware Write Protection is disabled when either the WP pin is high or the WPEN bit is zero. When the device is hardware write protected, writes to the Status Register, including the Block Protect bits and the WPEN bit, and the block protected sections in the memory array are disabled. Writes are only allowed to sections of the memory which are not block protected (see Table 6-5). Note: When the WPEN bit is hardware write protected, it cannot be changed back to zero, as long as the WP pin is held low. Table 6-5. WPEN Operation WPEN WP WEN Protected Blocks Unprotected Blocks Status Register 0 x 0 Protected Protected Protected 0 x 1 Protected Writable Writable 1 Low 0 Protected Protected Protected 1 Low 1 Protected Writable Protected X High 0 Protected Protected Protected X High 1 Protected Writable Writable Read Sequence (READ): Reading the AT25M01 via the SO pin requires the following sequence. After the CS line is pulled low to select a device, the Read opcode is transmitted via the SI line followed by the a 3-byte address to be read (see Table 6-6 on page 10). Upon completion, any data on the SI line will be ignored. The data (D7 – D0) at the specified address is then shifted out onto the SO line. If only one byte is to be read, the CS line should be driven high after the data comes out. The read sequence can be continued since the byte address is automatically incremented and data will continue to be shifted out. When the highest address is reached, the address counter will roll over to the lowest address allowing the entire memory to be read in one continuous read cycle. AT25M01 [DATASHEET] Atmel-8824E-SEEPROM-AT25M01-Datasheet_052016 9 Write Sequence (Write): In order to program the AT25M01, two separate instructions must be executed. First, the device must be write enabled via the Write Enable (WREN) Instruction. Then, a Write instruction may be executed. Also, the address of the memory location(s) to be programmed must be outside the protected address field location selected by the block write protection level. During an internal write cycle, all commands will be ignored except the RDSR instruction. A Write Instruction requires the following sequence. After the CS line is pulled low to select the device, the Write opcode is transmitted via the SI line followed by the byte address and the data (D7 – D0) to be programmed (see Table 6-6). Programming will start after the CS pin is brought high. (The Low-to-High transition of the CS pin must occur during the SCK low time immediately after clocking in the D0 (LSB) data bit. The Ready/Busy status of the device can be determined by initiating a Read Status Register (RDSR) Instruction. If Bit 0 = 1, the Write cycle is still in progress. If Bit 0 = 0, the Write cycle has ended. Only the Read Status Register instruction is enabled during the Write programming cycle. The AT25M01 is capable of a 256-byte Page Write operation. After each byte of data is received, the eight low order address bits are internally incremented by one; the high order bits of the address will remain constant. If more than 256 bytes of data are transmitted, the address counter will roll-over and the previously written data will be overwritten. The AT25M01 is automatically returned to the write disable state at the completion of a Write cycle. Note: If the device is not Write Enabled (WREN), the device will ignore the Write instruction and will return to the standby state, when CS is brought high. A new CS falling edge is required to re-initiate the serial communication. Table 6-6. Note: 10 Address Key Address AT25M01 A(n) A23 A0 The A23 through A17 address bits of the most significant address byte are don’t care values as these bits fall outside the addressable 1Mbit range.
