Am29DL32xG

Features:

The SecSi^TM (Secured Silicon) Sector is an extra sector capable of being permanently locked by AMD or cus-tomers. The SecSi Indicator Bit (DQ7) is perma-nently set to a 1 if the part is factory locked, and set to a 0 if customer lockable. This way, customer lock-able parts can never be used to replace a factory locked part. Current version of device has 256 bytes,which differs from previous versions of thisdevice.
Factory locked parts provide several options. The SecSi Sector may store a secure, random 16 byte ESN (Electronic Serial Number), customer code (pro-grammed through AMD's ExpressFlash service), or both.

Description

   The Am29DL32xG family consists of 32 megabit, 3.0 volt-only flash memory devices, organized as 2,097,152 words of 16 bits each or 4,194,304 bytes of 8 bits each. Word mode data appears on DQ15DQ0;byte mode data appears on DQ7DQ0. The device is designed to be programmed in-system with the stan-dard 3.0 volt V_CCsupply, and can also be programmed in standard EPROM programmers.
    The devices are available with an access time of 70,90, or 120 ns. Am29DL32xG are offered in 48-pin TSOP,48-ball or 63-ball FBGA, and 64-ball Fortified BGA packages. Standard control pins-chip enable (CE#),write enable (WE#), and output enable (OE#)-control normal read and write operations, and avoid bus con-tention issues.
   Am29DL32xG requires only a single 3.0 volt power supply for both read and write functions. Internally generated and regulated voltages are provided for the program and erase operations.
