Am29LV320D
32 Megabit (4 M x 8-Bit/2 M x 16-Bit)
CMOS 3.0 Volt-only, Boot Sector Flash Memory
DISTINCTIVE CHARACTERISTICS
ARCHITECTURAL ADVANTAGES
Secured Silicon
— 64 Kbyte Sector Size; Replacement/substitute
devices (such as Mirrorbit
) have 256 bytes.
—
Factory locked and identifiable:
16 bytes (8 words)
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 programmed once and
then permanently locked after being shipped from
AMD
Zero Power Operation
— Sophisticated power management circuits reduce
power consumed during inactive periods to nearly
zero.
Package options
— 48-pin TSOP
— 48-ball FBGA
Sector Architecture
— Eight 8 Kbyte sectors
— Sixty-three 64 Kbyte sectors
Top or bottom boot block
Manufactured on 0.23 μm process technology
Compatible with JEDEC standards
— Pinout and software compatible with
single-power-supply flash standard
PERFORMANCE CHARACTERISTICS
High performance
— Access time as fast 90 ns
— Program time: 7μs/word typical utilizing Accelerate
function
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
Minimum 1 million erase cycles guaranteed per
sector
20 Year data retention at 125°C
— Reliable operation for the life of the system
SOFTWARE FEATURES
Supports Common Flash Memory Interface (CFI)
Erase Suspend/Erase Resume
— Suspends erase operations to allow programming in
non-suspended sectors
Data# Polling and Toggle Bits
— Provides a software method of detecting the status of
program or erase cycles
Unlock Bypass Program command
— Reduces overall programming time when issuing
multiple program command sequences
HARDWARE FEATURES
Any combination of sectors can be erased
Ready/Busy# output (RY/BY#)
— Hardware method for detecting program or erase
cycle completion
Hardware reset pin (RESET#)
— Hardware method of resetting the internal state
machine to the read mode
WP#/ACC input pin
— Write protect (WP#) function allows protection of two
outermost boot sectors, regardless of sector protect
status
— Acceleration (ACC) function provides accelerated
program times
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
