LE25U40CQH

Ordering number : ENA2094 LE25U40CQH CMOS IC 4M-bit (512K×8) Serial Flash Memory http://onsemi.com Overview The LE25U40CQH is a SPI bus flash memory device with a 4M bit (512K × 8-bit) configuration that adds a high performance Dual output and Dual I/O function. It uses a single 2.5v power supply. While making the most of the features inherent to a serial flash memory device, the LE25U40CQH is housed in an 8-pin ultra-miniature package. All these features make this device ideally suited to storing program in applications such as portable information devices, which are required to have increasingly more compact dimensions. The LE25U40CQH also has a small sector erase capability which makes the device ideal for storing parameters or data that have fewer rewrite cycles and conventional EEPROMs cannot handle due to insufficient capacity. Features Read/write operations enabled by single 2.5v power supply: 2.3 to 3.6V supply voltage range Operating frequency : 40MHz Temperature range : -40 to 85°C Serial interface : SPI mode 0, mode 3 supported / Dual Output, Dual I/O supported Sector size : 4K bytes/small sector, 64K bytes/sector Small sector erase, sector erase, chip erase functions Page program function (256 bytes / page) Block protect function Highly reliable read/write Number of rewrite times : 100,000 times Small sector erase time : 40ms (typ.), 150ms (max.) Sector erase time : 80ms (typ.), 250ms (max.) Chip erase time : 250ms (typ.), 2...
