20 / 80 page  19 AT45DB161E DS-AT45DB161E–8782N–03-2021 Table 7-1. Block Erase Addressing 7.9 Sector Erase The Sector Erase command can be used to individually erase any sector in the main memory. The main memory array is comprised of 17 sectors. Only one sector can be erased at a time. To erase Sector 0a or Sector 0b with the standard DataFlash page size (528 bytes), opcode 7Ch must be clocked into the device, followed by three address bytes comprised of two dummy bits, nine page address bits (PA11 - PA3), and 13 dummy bits. To erase Sector 1-15, opcode 7Ch must be clocked into the device, followed by three address bytes comprised of two dummy bits, four page address bits (PA11 - PA8), and 18 dummy bits. To erase Sector 0a or Sector 0b with the binary page size (512 bytes), opcode 7Ch must be clocked into the device followed by three address bytes comprised of three dummy bits, nine page address bits (A20 - A12), and 12 dummy bits. To erase Sector 1-15 erase, opcode 7Ch must be clocked into the device, followed by three dummy bits, four page address bits (A20 - A17), and 17 dummy bits. The page address bits are used to specify any valid address location within the sector to be erased. When the CS pin transitions from low-to high, the device erases the selected sector. This operation is internally timed and takes a maximum time of tSE. During this time, the RDY/BUSY bit in the Status Register indicates that the device is busy. The device also incorporates an intelligent algorithm that can detect when a byte location fails to erase properly. If an erase error arises, it is indicated by the EPE bit in the Status Register.
