MSM9894AL

E2D0095-19-22 ¡ Semiconductor MSM9894AL ¡ Semiconductor 8M-bit Serial Voice Flash Memory This version: Feb. 1999 MSM9894AL GENERAL DESCRIPTION The MSM9894AL is a 8Mb flash memory that operates at 2.7 V to 3.6 V. Since backup is not needed, the number of pins is small, and the chip is contained in a small-package 32-pin TSOP, the MSM9894AL is a flash memory suitable for applications such as handy terminals. In combination with Oki's recording/playback IC (MSM9888L/MSM9889L), a solid-state recording/ playback system can be easily constructed.
