Simultaneous Operation Flash Memory - Advanced Micro Devices
Description
PRELIMINARY
Am29DL16xC
16 Megabit (2 M x 8-Bit/1 M x 16-Bit) CMOS 3.
0 Volt-only, Simultaneous Operation Flash Memory
DISTINCTIVE CHARACTERISTICS
ARCHITECTURAL ADVANTAGES s Simultaneous Read/Write operations — Data can be continuously read from one bank while executing erase/program functions in other bank — Zero latency between read and write operations s Multiple bank architectures — Three devices available with different bank sizes (refer to Table 2) s Secured Silicon (SecSi) Sector: Extra 64 KByte 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: Can be read, programmed, or erased just like other sectors.
Once locked, data cannot be changed s Zero Power Operation — Sophisticated power management circuits reduce power consumed during inactive periods to nearly zero s Package options — 48-ball FBGA — 56-pin SSOP — 48-pin TSOP s Top or bottom boot block s Manufactured on 0.
32 µm process technology s Compatible with JEDEC standards — Pinout and software compatible with single-power-supply flash standard PERFORMANCE CHARACTERISTICS s High performance — Access time as fast 70 ns — Program time: 7 µs/word typical utilizing Accelerate function s Ultra low power consumption (typical values) — 2 mA active read current at 1 MHz — 10 mA active read current at 5 MHz — 200 nA in standby or automatic sleep mode s Minimum 1 million write cycles guaranteed per sector s 20 Year data retention at 125°C — Reliable operation for the life of the system SOFTWARE FEATURES s Data Management Software (DMS) — AMD-supplied software manages data programming and erasing, enabling EEPROM emulation — Eases sector erase limitations s Supports Common Flash Memory Interface (CFI) s Erase Suspend/Erase Resume — Suspends erase operations to allow programming in same bank s Data...
