LE25S81A: Serial Flash Memory, 8 Mb (1024K x 8)

The LE25S81A is a SPI bus flash memory device with a 8M bit (1024K x 8-bit) configuration. It uses a single power supply. While making the most of the features inherent to a serial flash memory device, the LE25S81A 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 LE25S81A 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

Operations power supply: : 1.65 to 1.95V supply voltage range
Operating frequency : 70MHz (max)
Temperature range : -40 to +90°C
Serial interface : SPI mode 0, mode 3 supported

Sector size : 4K bytes/small sector, 64K bytes/sector
Erase functions :Small Sector Erase (SSE), Sector Erase (SE), Chip Erase (CHE)
Page program function : 256 bytes /page
Status functions : Ready/Busy information, protect information
Low operation current :5.0mA (Low-power program mode, typ),3.0mA (Low-Power Read mode, typ)
Erase time : 10ms (SSE, typ), 15ms (SE, typ), 120ms (CHE, typ)
Page program time (tPP) :0.3ms/256 bytes (typ), 0.5ms/256 bytes (max)
Emergency shutdown of the current consumption: transition to a standby state in less than 20µs from the active by Write Suspend: transition to a standby state in less than 40µs from the active by Software Reset
High reliability: 100,000 erase/program cycles: 20 years data retention period
