LE25U40PCMC Serial Flash Memory 4 Mb (512K x 8) www.onsemi.com Overview The LE25U40PCMC 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 2.5 V power supply. While making the most of the features inherent to a serial flash memory device, the LE25U40PCMC 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 LE25U40PCMC also has a small sector erase capability which makes the device ideal for storing parameters or data that have fewer SOIC-8 / SOP8J (200 mil) rewrite cycles and conventional EEPROMs cannot handle due to insufficient capacity. Features Read/write operations enabled by single 2.5 V power supply : 2.3 to 3.6 V supply voltage range Operating frequency : 30 MHz Temperature range : 40 to +105C 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 : 40 ms (typ), 150 ms (max) Sector erase time : 80 ms (typ), 250 ms (max) Chip erase time : 250 ms (typ.), 2.0 s (max) Page program time : 4.0 ms / 256 bytes (typ), 5.0 ms / 256 bytes (max) Status functions : Ready/busy information, protect information Data retention period : 20 years Package : SOP8J (200 mil), CASE 751CU * This product is licensed from Silicon Storage Technology, Inc. (USA). ORDERING INFORMATION See detailed ordering and shipping information on page 23 of this data sheet.
