The Numonyx™ StrataFlash® Wireless Memory (L18) provides read-while-write and read-while-erase capability with density upgrades through 256-Mbit. This family of devices provides high performance at low voltage on a 16-bit data bus. Individually erasable memory blocks are sized for optimum code and data storage.

■ High performance Read-While-Write/Erase
  — 85 ns initial access
  — 54 MHz with zero wait state, 14 ns clock-to-data output synchronous-burst mode
  — 25 ns asynchronous-page mode
  — 4-, 8-, 16-, and continuous-word burst mode
  — Burst suspend
  — Programmable WAIT configuration
  — Buffered Enhanced Factory Programming (BEFP) at 5 µs/byte (Typ)
  — 1.8 V low-power buffered programming at 7 µs/byte (Typ)
■ Architecture
  — Asymmetrically-blocked architecture
  — Multiple 8-Mbit partitions: 128-Mbit devices
  — Multiple 16-Mbit partitions: 256-Mbit devices
