—
AMD-supplied software manages data programming and
erasing, enabling EEPROM emulation
Eases sector erase limitations
■ High performance
—
Access time as fast as 70 ns
—
■ Package
■ Supports Common Flash Memory Interface (CFI)
■ Erase Suspend/Erase Resume
—
73-Ball FBGA
■ Operating Temperature
—
Suspends erase operations to allow programming in same
bank
—
–40°C to +85°C
■ Data# Polling and Toggle Bits
Flash Memory Features
—
Provides a software method of detecting the status of
program or erase cycles
ARCHITECTURAL ADVANTAGES
■ Unlock Bypass Program command
■ Simultaneous Read/Write operations
—
Reduces overall programming time when issuing multiple
program command sequences
—
Data can be continuously read from one bank while
executing erase/program functions in other bank
Zero latency between read and write operations
—
HARDWARE FEATURES
■ Secured Silicon (SecSi) Sector: Extra 256 Byte sector
■ Any combination of sectors can be erased
—
Factory locked and identifiable: 16 bytes available for
secure, random factory Electronic Serial Number; verifiable
as factory locked through autoselect function.
Customer lockable: Sector is one-time programmable. Once
locked, data cannot be changed
■ 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
■ Zero Power Operation
Sophisticated power management circuits reduce power
consumed during inactive periods to nearly zero
—
■ WP#/ACC input pin
—
Write protect (WP#) function allows protection of two outermost
boot sectors, regardless of sector protect status
■ Top or bottom boot block
■ Manufactured on 0.17 µm process technology
■ Compatible with JEDEC standards
—
Acceleration (ACC) function accelerates program timing
■ Sector protection
—
Pinout and software compatible with single-power-supply
flash standard
—
Hardware method of locking a sector, either in-system or
using programming equipment, to prevent any program or
erase operation within that sector
PERFORMANCE CHARACTERISTICS
