Control
DISTINCTIVE CHARACTERISTICS
ARCHITECTURAL ADVANTAGES
I
128Mbit Page Mode device
— Word (16-bit) or double word (32-bit) mode selectable via
WORD# input
— Page size of 8 words/4 double words: Fast page read access
from random locations within the page
I
Single power supply operation
— Full Voltage range: 2.7 to 3.6 volt read, erase, and program
operations for battery-powered applications
I
Simultaneous Read/Write Operation
— Data can be continuously read from one bank while
executing erase/program functions in another bank
— Zero latency switching from write to read operations
I
FlexBank Architecture
— 4 separate banks, with up to two simultaneous operations
per device
— Organized as two 16 Mbit banks (Bank 1 & 4) and two 48
Mbit banks (Bank 2 & 3)
VersatileI/O
TM
(V
IO
) Control
— Output voltage generated and input voltages tolerated on the
device is determined by the voltage on the V
IO
pin
SecSi (Secured Silicon) Sector region
— 128 words (64 double words) accessible through a
command sequence
I
I
I
Both top and bottom boot blocks in one device
I
Manufactured on 0.17 μm process technology
I
20-year data retention at 125°C
I
Minimum 1 million write cycle guarantee per sector
PERFORMANCE CHARACTERISTICS
I
High Performance

I
Power consumption (typical values at 10 MHz)
—
38 mA active read current
—
17 mA program/erase current
—
1.5 μA typical standby mode current
SOFTWARE FEATURES
I
Software command-set compatible with JEDEC 42.4
standard
—
Backward compatible with Am29F and Am29LV families
I
CFI (Common Flash Interface) complaint
—
Provides device-specific information to the system, allowing
host software to easily reconfigure for different Flash devices
I
Erase Suspend / Erase Resume
—
Suspends an erase operation to allow read or program
operations in other sectors of same bank
I
Unlock Bypass Program command
—
Reduces overall programming time when issuing multiple
program command sequences
HARDWARE FEATURES
I
Ready/Busy# pin (RY/BY#)
—
Provides a hardware method of detecting program or erase
cycle completion
I
Hardware reset pin (RESET#)
—
Hardware method to reset the device to reading array data
I
WP# (Write Protect) input
—
At V
, protects the two top and two bottom sectors,
regardless of sector protect/unprotect status
—
At V
IH
, allows removal of sector protection
—
An internal pull up to Vcc is provided
I
Persistent Sector Protection
—
A command sector protection method to lock combinations
of individual sectors and sector groups to prevent program or
erase operations within that sector
—
Sectors can be locked and unlocked in-system at V
CC
level
Password Sector Protection
—
A sophisticated sector protection method to lock
combinations of individual sectors and sector groups to
prevent program or erase operations within that sector using
a user-defined 64-bit password
I
I
ACC (Acceleration) input provides faster programming
times in a factory setting
