HGSEMI HG25Q64MW/TR

The HG25Q64 (64M-bit) Serial Flash memory provides a storage solution for systems with limited space, pins and power. The 25S 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 3.0V to 3.6V power supply with current consumption as low as 3μA for power-down. All devices are offered in space-saving packages. The HG25Q64 array is organized into 32,768 programmable pages of 256-bytes each. Up to 256 bytes can be programmed at a time. Pages can be erased in groups of 16 (4KB sector erase), groups of 128 (32KB block erase), groups of 256 (64KB block erase) or the entire chip (chip erase). The HG25Q64 has 2,048 erasable sectors and 128 erasable blocks respectively. The small 4KB sectors allow for greater flexibility in applications that require data and parameter storage. The HG25Q64 supports the standard Serial Peripheral Interface (SPI), Dual/Quad I/O SPI: Serial Clock, Chip Select, Serial Data I/O0 (DI), I/O1 (DO), I/O2 and I/O3. SPI clock frequencies of HG25Q64 of up to 104MHz are supported allowing equivalent clock rates of 208MHz (104MHz x 2) for Dual and 532MHz (80MHz x 4) for Quad when using the Fast Read Dual/Quad I/O. These transfer rates can outperform standard Asynchronous 8 and 16-bit Parallel Flash memories. Additionally, the device supports JEDEC standard manufacturer and device ID, and a 64-bit Unique Serial Number and three 256-bytes Security Registers.
