Am29DL162D/163D/164D
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
■ Minimum 1 million write cycles guaranteed per sector
■ Simultaneous Read/Write operations
■ 20 Year data retention at 125°C
— Data can be continuously read from one bank while
executing erase/program functions in other bank
— Reliable operation for the life of the system
SOFTWARE FEATURES
— Zero latency between read and write operations
■ Data Management Software (DMS)
■ Multiple bank architectures
— AMD-supplied software manages data programming
and erasing, enabling EEPROM emulation
— Three devices available with different bank sizes (refer
to Table 2)
— Eases sector erase limitations
■ SecSi (Secured Silicon) Sector: Extra 64 KByte
■ Supports Common Flash Memory Interface (CFI)
sector
■ Erase Suspend/Erase Resume
— Suspends erase operations to allow programming in
same bank
— 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
■ Data# Polling and Toggle Bits
— Provides a software method of detecting the status of
program or erase cycles
— Customer lockable: Can be read, programmed, or
erased just like other sectors. Once locked, data
cannot be changed
■ Unlock Bypass Program command
— Reduces overall programming time when issuing
multiple program command sequences
■ Zero Power Operation
— Sophisticated power management circuits reduce
power consumed during inactive periods to nearly
zero
HARDWARE FEATURES
■ Any combination of sectors can be erased
■ Package options
— 48-ball FBGA
— 48-pin TSOP
■ Ready/Busy# output (RY/BY#)
— Hardware method for detecting program or erase
cycle completion
■ Top or bottom boot block
■ Hardware reset pin (RESET#)
— Hardware method of resetting the internal state
machine to reading array data
■ Manufactured on 0.23 µm process technology
— Compatible with Am29DL16xC devices
■ Compatible with JEDEC standards
■ WP#/ACC input pin
— Write protect (WP#) function allows protection of two
outermost boot sectors, regardless of sector protect status
— Pinout and software compatible with
single-power-supply flash standard
— Acceleration (ACC) function accelerates program
timing
PERFORMANCE CHARACTERISTICS
■ Sector protection
■ High performance
— Hardware method of locking a sector, either
in-system or using programming equipment, to
prevent any program or erase operation within that
sector
— Access time as fast 70 ns
— Program time: 7 µs/word typical utilizing Accelerate function
■ Ultra low power consumption (typical values)
— 2 mA active read current at 1 MHz
— Temporary Sector Unprotect allows changing data in
protected sectors in-system
— 10 mA active read current at 5 MHz
— 200 nA in standby or automatic sleep mode
