GENERAL DESCRIPTION Advanced Security Features - Write protect all/portion of memory via software - Enable/Disable protection with WP# Pin Space Efficien Packaging - 8-pin SOIC 208/150-mil - 8-pad USON 2x3-mm - TSSOP8 (173mil) - Contact Zetta for KGD and other options The ZD25Q40 (4M-bit) Serial Flash memory provides a storage solution for systems with limited space, pins and power. The ZD25Q40 series offers flexibility and performance well beyond ordinary Serial Flash devices. They are ideal for code shadowing to RAM, executing code directly from Dual/Quad SPI (XIP) and storing voice, text and data. The device operates on a single 2.7V to 3.6V power supply with current consumption as low as 10m A active and 1µA for power-down. All devices are offered in space- saving packages. The ZD25Q40 support the standard Serial Peripheral Interface (SPI), as well as Dual/Quad I/O SPI: 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 108MHz are supported allowing equivalent clock rates of 216MHz (108MHz x 2) for Dual I/O and 432MHz (108MHz x 4) for Quad I/O when using the Fast Read Dual/Quad I/O instructions. These transfer rates can outperform standard Asynchronous 8 and 16-bit Parallel Flash...
