GENERAL DESCRIPTION
The MSM 9893L is a 4Mb 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 28-pin TSOP or 30-pin SSOP, the MSM9893L 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.
