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 (SecSi Sector)
— 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
TM
■
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
■
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
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
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
