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
SOFTWARE FEATURES
■ Secured Silicon (SecSi) Sector: 256-byte sector
■ Supports Common Flash Memory Interface (CFI)
— 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
■ 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
— Customer lockable: Customer may program own
custom data. Once locked, data cannot be changed
■ 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
HARDWARE FEATURES
■ Package options
— 48-ball FBGA
— 48-pin TSOP
■ Any combination of sectors can be erased
■ Ready/Busy# output (RY/BY#)
— Hardware method for detecting program or erase
cycle completion
■ Top or bottom boot block
■ Manufactured on 0.32 µm process technology
■ Hardware reset pin (RESET#)
— Hardware method of resetting the internal state
machine to reading array data
■ Compatible with JEDEC standards
— Pinout and software compatible with single-power-
supply flash standard
■ WP#/ACC input pin
— Write protect (WP#) function allows protection of two
outermost boot sectors, regardless of sector protect status
PERFORMANCE CHARACTERISTICS
■ High performance
— Acceleration (ACC) function accelerates program
timing
— Access time as fast 90 ns
— Program time: 8 µs/word typical using Accelerate
■ 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
■ Ultra low power consumption (typical values)
— 1 mA active read current at 1 MHz
— 5 mA active read current at 5 MHz
— Temporary Sector Unprotect allows changing data in
protected sectors in-system
— 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
