Description
Flexible Architecture with 4KB sectors - Uniform Sector Erase (4K-bytes) - Uniform Block Erase (32K and 64K-bytes) - Program 1 to 256 byte per programmable page Advanced Security Features - Write protect all/portion of memory via software - Enable/Disable protection with WP# Pin - 4K-Bit secured OTP Space Efficien Packaging - 8-pin SOIC 208-mil / VSOP8 - 8-pad WSON 6x5-mm - SOP16 (300mil) - Contact Zetta for KGD and other options The ZD25LQ64 supports the standard Serial Peripheral Interface (SPI), and Quad Peripheral Interface (QPI): Serial Clock, Chip Select, Serial Data I/O0(DI), I/O1(DO), I/O2(/WP), and I/O3(/HOLD). SPI clock frequencies of up to 133MHz are supported allowing equivalent clock rates of 266MHz for Dual Output and 532MHz for Quad Output when using the QPI and Fast Read Dual/Quad I/O instructions.
