Description  
The Atmel® AT25010B/020B/040B provides 1,024/2,048/4,096 bits of Serial  
Electrically Erasable Programmable Read-Only Memory (EEPROM) organized as  
128/256/512 words of 8 bits each. The device is optimized for use in many  
automotive applications where low-power and low-voltage operation are essential.  
AT25010B/020B/040B is available in space-saving 8-lead JEDEC SOIC, 8-lead  
TSSOP, and 8-pad UDFN Packages.  
AT25010B/020B/040B 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 one of  
four blocks 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. The  
HOLD pin may be used to suspend any serial communication without resetting the  
serial sequence.

Serial Interface Description  
Master: The device that generates the serial clock.  
Slave: Because the Serial Clock pin (SCK) is always an input, AT25010B/020B/040B always operates as a  
slave.  
Transmitter/Receiver: AT25010B/020B/040B 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. The opcode also contains address bit A8 in both the  
Read and the Write instructions for AT25040B only.  
Invalid Opcode: If an invalid opcode is received, no data will be shifted into AT25010B/020B/040B, 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: AT25010B/020B/040B 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 AT25010B/020B/040B. 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, all write operations are inhibited. WP going low while CS is still low will interrupt a write to  
AT25010B/020B/040B. If the internal write cycle has already been initiated, WP going low will have no effect on  
any write operation.

Functional Description  
AT25010B/020B/040B is designed to interface directly with the synchronous Serial Peripheral Interface (SPI) of  
the 6805 and 68HC11 series of microcontrollers.  
AT25010B/020B/040B 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.

Note:  
“A” represents the ninth address bit (MSB bit A8) needed for AT25040B only.  
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.

Write Status Register (WRSR): The WRSR instruction allows the user to select one of four levels of protection.  
AT25010B/020B/040B is divided into four array segments. One-quarter, one-half, 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.

Bits BP0 and BP1 are nonvolatile cells that have the same properties and functions as the regular memory cells

Read Sequence (Read): Reading AT25010B/020B/040B via the Serial Output (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 byte address to be read (A7–A0, see Table 6-5). 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.  
Write Sequence (Write): In order to program AT25010B/020B/040B, two separate instructions must be  
executed. First, the device must be Write Enabled via the 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 (A7A0) and the data (D7–D0) to be  
programmed (See Table 6-5). 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 = one, the Write cycle is still in progress. If Bit 0 = zero, the Write cycle has ended. Only the RDSR  
instruction is enabled during the Write programming cycle.  
AT25010B/020B/040B is capable of a 8-byte Page Write operation. After each byte of data is received, the three  
low-order address bits are internally incremented by one; the high-order bits of the address will remain constant.  
If more than eight bytes of data are transmitted, the address counter will roll over and the previously written data  
will be overwritten. AT25010B/020B/040B 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 reinitiate the serial  
communication.

Power Recommendation  
The device internal POR (Power-On Reset) threshold is just below the minimum device operating voltage.  
Power shall rise monotonically from 0.0Vdc to full VCC in less than 1ms. Hold at full VCC for at least 100μs before  
the first operation. Power shall drop from full VCC to 0.0Vdc in less than 1ms. Power dropping to a non-zero level  
and then slowly going to zero is not recommended. Power shall remain off (0.0Vdc) for 0.5s minimum. Please  
consult Atmel if your power conditions do not meet the above recommendations.
