6 at25010a/020a/040a 3348h?seepr?9/04 serial interface description master: the device that generates the serial clock. slave: because the serial clock pin (sck) is always an input, the at25010a/020a/040a always operates as a slave. transmitter/receiver: the at25010a/020a/040a 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 op-code: after the device is selected with cs going low, the first byte will be received. this byte contains the op-code that defines the operations to be performed. the op-code also contains address bit a8 in both the read and write instructions. invalid op-code: if an invalid op-code is received, no data will be shifted into the at25010a/020a/040a, 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 at25010a/020a/040a 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 so pin will remain in a high impedance state. hold: the hold pin is used in conjunction with the cs pin to select the at25010a/020a/040a. 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 the at25010a/020a/040a. if the internal write cycle has already been initiated, wp going low will have no effect on any write operation.

8 at25010a/020a/040a 3348h?seepr?9/04 functional description the at25010a/020a/040a is designed to interface directly with the synchronous serial peripheral interface (spi) of the 6805 and 68hc11 series of microcontrollers. the at25010a/020a/040a utilizes an 8-bit instruction register. the list of instructions and their operation codes are contained in figure 5. all instructions, addresses, and data are transferred with the msb first and start with a high-to-low cs transition. note: ?a? represents msb address bit a8. write enable (wren): the device will power up in the write disable state when v cc is applied. all programming instructions must therefore be preceded by a write enable instruction. the wp pin must be held high during a wren instruction. write disable (wrdi): to protect the device against inadvertent writes, the write disable instruction disables all programming modes. the wrdi instruction is indepen- dent of the status of the wp pin. read status register (rdsr): the read status register instruction provides access to the status register. the read/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. the at25010a/020a/040a is divided into four array seg- ments. one-quarter, one-half, or all of the memory segments can be protected. any of table 5. instruction set for the at25010a/020a/040a 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 a011 read data from memory array write 0000 a010 write data to memory array table 6. status register format bit 7 bit 6 bit 5 bit 4 bit 3 bit 2 bit 1 bit 0 x x x x bp1 bp0 wen rdy table 7. read status register bit definition 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 8. bit 3 (bp1) see table 8. bits 4?7 are ?0?s when device is not in an internal write cycle. bits 0?7 are ?1?s during an internal write cycle.
9 at25010a/020a/040a 3348h?seepr?9/04 the data within any selected segment will therefore be read only. the block write protec- tion levels and corresponding status register control bits are shown in table 8. bits bp1 and bp0 are nonvolatile cells that have the same properties and functions as the regular memory cells (e.g., wren, t wc , rdsr). read sequence (read): reading the at25010a/020a/040a via the so pin requires the following sequence. after the cs line is pulled low to select a device, the read op-code (including a8) is transmitted via the si line followed by the byte address to be read (a7 ? a0). 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 the at25010a/020a/040a, the write protect pin (wp ) must be held high and two separate instructions must be executed. first, the device must be write enabled via the wren instruction. then a write (write) instruction may be executed. also, the address of the memory location(s) to be pro- grammed 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 op-code (including a8) is transmitted via the si line fol- lowed by the byte address (a7 ? a0) and the data (d7 ? d0) to be programmed. 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 reg- ister (rdsr) instruction. if bit 0 = ?1?, the write cycle is still in progress. if bit 0 = ?0?, the write cycle has ended. only the rdsr instruction is enabled during the write program- ming cycle. the at25010a/020a/040a is capable of an 8-byte page write operation. after each byte of data is received, the three low-order address bits are internally incremented by one; the six high-order bits of the address will remain constant. if more than 8 bytes of data are transmitted, the address counter will roll over and the previously written data will be overwritten. the at25010a/020a/040a is automatically returned to the write disable state at the completion of a write cycle. note: if the wp pin is brought low or 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. table 8. block write protect bits level status register bits array addresses protected bp1 bp0 at25010a at25020a at25040a 0 0 0 none none none 1 (1/4) 0 1 60 ? 7f c0 ? ff 180 ?1 ff 2 (1/2) 1 0 40 ? 7f 80 ? ff 100 ? 1ff 3 (all) 1 1 00 ? 7f 00 ? ff 000 ? 1ff
