Am29LV160D Flash Memory

General Description

The Am29LV160D 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 48-ball FBGA, 44-pin SO, and 48-pin TSOP packages. 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.

• Erase Suspend/Erase Resume
• Suspends an erase operation to read data from, or program data to, a sector that is not being erased, then resumes the erase operation
• Hardware reset pin (RESET#)
• Hardware method to reset the device to reading array data
