描述 Description

GENERAL DESCRIPTION
The AS29LV016J is a 16 Mbit, 3.0 Volt-only Flash memory organized as 2,097,152 bytes or 1,048,576 words. The device is offered in a 48-pin TSOP package. The word-wide data (x16) appears on DQ15–DQ0; the byte-wide (x8) data appears on DQ7–DQ0. This device is designed to be programmed in system with the standard system 3.0 volt VCC supply. A 12.0 V VPP or 5.0 VCC are not required for write or erase operations. The device can also be programmed in standard EPROM programmers.DISTINCTIVE CHARACTERISTICS
