Am29SL160C
16 Megabit (2 M x 8-Bit/1 M x 16-Bit)
CMOS 1.8 Volt-only Super Low Voltage Flash Memory
DISTINCTIVE CHARACTERISTICS
ARCHITECTURAL ADVANTAGES
■
Secured Silicon (SecSi) Sector: 256-byte 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:
Customer may program own
custom data. Once locked, data cannot be changed
■
Zero Power Operation
— Sophisticated power management circuits reduce
power consumed during inactive periods to nearly
zero
■
Package options
— 48-ball FBGA
— 48-pin TSOP
■
Top or bottom boot block
■
Manufactured on 0.32 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: 8 μs/word typical using Accelerate
■
Ultra low power consumption (typical values)
— 1 mA active read current at 1 MHz
— 5 mA active read current at 5 MHz
— 1 μA 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
same bank
■
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 reading array data
■
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
■
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
