23 / 138 page  Datasheet 23 of 138 002-18216 Rev. *W 2022-01-18 256Mb/512Mb/1Gb SEMPER™ Flash Octal interface, 1.8V/3.0V Address space maps 3 Address space maps The HL-T/HS-T family supports 32-bit (4-Byte) addresses only to enable 256Mb or 512Mb or 1Mb density devices. 4-Byte addresses allow direct addressing of up to 4Mb (32Mb) address space. Besides Flash memory array, HL-T/HS-T family includes separate address spaces for Manufacturer ID, Device ID, Unique ID, Serial Flash Discoverable Parameters (SFDP), Secure Silicon Region (SSR), and Registers. Figure 35 HL-T/HS-T address space map overview 3.1 SEMPER™ Flash memory array The main flash array is divided into units called physical sectors. The HL-T/HS-T family sector architecture supports the following options: • 256Mb, 512Mb, 1Gb supports 256KB Uniform sector options • 256Mb, 512Mb, 1Gb Hybrid sector options - Physical set of thirty-two 4KB sectors and one 128KB sector at the top or bottom of address space with all remaining sectors of 256KB - Physical set of sixteen 4KB sectors and one 192KB sector at both the top and bottom of the address space with all remaining sectors of 256KB The combination of the sector architecture selection bits in Configuration Register-1 and Configuration Register-3 support the different sector architecture options of the HL-T/HS-T family. See Registers on page 75 for more information.
