64 Megabit (8 M x 8 Bit/4 M x 16 Bit) CMOS 3.0 Volt only, Simultaneous Operation Flash Memory and 32 Mbit (512 K x 16-Bit) Pseudo Static RAM with Page Mode
General Description
Am29DL640G Features
The Am29DL640G is a 64 megabit, 3.0 volt-only flash memory device, organized as 4,194,304 words of 16 bits each or 8,388,608 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 standard 3.0 volt VCC supply, and can also be programmed in standard EPROM programmers.
Data can be continuously read from one bank while executing erase/program functions in another bank.
Zero latency between read and write operations
Flexible Bank™ architecture
Read may occur in any of the three banks not being written or erased.
Four banks may be grouped by customer to achieve desired bank divisions.
Manufactured on 0.17 µm process technology
SecSi™ (Secured Silicon) Sector: Extra 256 Byte sector
Factory locked and identifiable: 16 bytes available for secure, random factory Electronic Serial Number; verifiable as factory locked through autoselect function. ExpressFlash option allows entire sector to be available for factory-secured data
Customer lockable: Sector is one-time programmable. Once sector is locked, data cannot be changed.
Zero Power Operation
Sophisticated power management circuits reduce power consumed during inactive periods to nearly zero.
Boot Sectors
Top and bottom boot sectors in the same device
Compatible with JEDEC standards
Pinout and software compatible with single-power-supply flash standard
