AM29DL16XC Datasheet, PDF (1/51 Pages) Advanced Micro Devices – 16 Megabit (2 M x 8-Bit/1 M x 16-Bit) CMOS 3.0 Volt-only, Simultaneous Operation Flash Memory

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# Polling and Toggle Bits
— Provides a software method of detecting the status of
program or erase cycles
s Unlock Bypass Program command
— Reduces overall programming time when issuing
multiple program command sequences
HARDWARE FEATURES
s Any combination of sectors can be erased
s Ready/Busy# output (RY/BY#)
— Hardware method for detecting program or erase
cycle completion
s Hardware reset pin (RESET#)
— Hardware method of resetting the internal state
machine to reading array data
s WP#/ACC input pin
— Write protect (WP#) function allows protection of two
outermost boot sectors, regardless of sector protect status
— Acceleration (ACC) function accelerates program
timing
s Sector protection
— Hardware method of locking a sector, either
in-system or using programming equipment, to
prevent any program or erase operation within that
sector
— Temporary Sector Unprotect allows changing data in
protected sectors in-system
