LE25S20XA: Serial Flash Memory, 2 Mb (256K x 8)

The LE25S20XA is a SPI bus flash memory device with a 2M bit (256K x 8-bit) configuration. It uses a single 1.8V power supply. While making the most of the features inherent to a serial flash memory device, the LE25S20XA is housed in an 8-pin ultra-miniature package. All these features make this device ideally suited to storing program in applications more compact dimensions. The LE25S20XA 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 1.95 V supply voltage range
  • Operating frequency : 40 MHz (max)
  • Temperature range : –40 to +85°C
  • Serial interface : SPI mode 0, mode 3 supported
  • Electronic Identification : JDEC ID, Device ID
  • 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: 6.0 mA (Read mode operation current, 40 MHz): 15 mA (Erase or Program mode operating current): 10 µA (CMOS standby current)
  • Erase time: 40 ms (SSE, typ), 80 ms (SE, typ), 300 ms (CHE, typ)
  • Page program time (tPP): 3.0 ms/256 bytes (typ.), 3.5 ms/256 bytes (max.)
  • High reliability: 100,000 erase/program cycles: 20 years data retention period
