PRELIMINARY
Am29DL162C/Am29DL163C
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
— Two devices available with different bank sizes (refer
to Table 3)
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
