... JEDEC SOIC, 8-lead UDFN, 8-lead XDFN, 8-lead TSSOP, and 8-ball VFBGA packages. The AT25320B/640B is enabled through the Chip Select pin (CS) and accessed via a three-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 sepa- rate erase cycle is required before write ...

... 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 “0”. This will allow the user to install the AT25320B/640B in a system with the 8535F–SEEPR–6/10 ...

... The Atmel AT25320B/640B is designed to interface directly with the synchronous serial peripheral interface (SPI) of the 6805 and 68HC11 series of microcontrollers. The AT25320B/640B utilizes an 8-bit instruction register. The list of instructions and their operation codes are con- tained in Table 3-1. All instructions, addresses, and data are transferred with the MSB first and start with a high-to- low CS transition ...

... X High X High READ SEQUENCE (READ): Reading the AT25320B/640B via the Serial Output (SO) pin requires the following sequence. After the CS line is pulled low to select a device, the read op-code is transmitted via the SI line followed by the byte address to be read (A15 The data (D7 D0) at the specified address is then shifted out onto the SO line. If only one byte read, the CS – ...

... 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 programming cycle. The AT25320B/640B is capable of a 32-byte page write operation. After each byte of data is received, the five low- order address bits are internally incremented by one; the high-order bits of the address will remain constant. If more than 32-bytes of data are transmitted, the address counter will roll over and the previously written data will be overwritten ...
