Product Summary
The AM29DL323GB-90EI consists of 32 megabit, 32M CMOS 3.0 Volt-only, Simultaneous Operation Flash Memory, organized as 2,097,152 words of 16 bits each or 4,194,304 bytes of 8 bits each. Word mode data appears on DQ15–DQ0; byte mode data appears on DQ7–DQ0. The device is designed to be programmed in-system with the AM29DL323GB-90EI are available with an access time of 70, 90, or 120 ns. The devices 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 contention issues. AM29DL323GB-90EI 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.
Parametrics
AM29DL323GB-90EI absolute maximum ratings: (1)Storage Temperature Plastic Packages:–65℃ to +150℃; (2)Ambient Temperature with Power Applied:–65℃ to +125℃; (3)Voltage with Respect to Ground VCC(Note 1):–0.5 V to +4.0 V; (4)A9, OE#, and RESET# (Note 2):–0.5 V to +12.5 V; (5)WP#/ACC:–0.5 V to +10.5 V; (6)All other pins (Note 1) : –0.5 V to VCC+0.5 V; (7)Output Short Circuit Current (Note 3):200 mA.
Features
AM29DL323GB-90EI features: (1)The Secured Silicon Sector is an extra sector capable of being permanently locked by AMD or customers.(2)The Secured Silicon Indicator Bit (DQ7) is permanently set to a 1 if the part is factory locked, and set to a 0 if customer lockable. This way, customer lockable parts can never be used to replace a factory locked part. (3)Current version of device has 256 bytes, which differs from previous versions of this device. (4)Factory locked parts provide several options. The Secured Silicon Sector may store a secure, random 16 byte ESN (Electronic Serial Number), customer code(programmed through AMD’s ExpressFlash service or both.
