Data Sheet
Distinctive Characteristics
Architectural Advantages
„ Single 1.8 volt read, program and erase (1.65 to
1.95 volt)
„ Manufactured on 0.11 µm process technology
„ Simultaneous Read/Write operation
— Data can be continuously read from one bank while
executing erase/program functions in other bank
— Zero latency between read and write operations
— Four bank architecture: WS128J: 16Mb/48Mb/48Mb/
16Mb, WS064J: 8Mb/24Mb/24Mb/8Mb
„ Programable Burst Interface

— Linear Burst: 8, 16, and 32 words with wrap-around
— Continuous Sequential Burst
„ Secured Silicon Sector region
— 128 words accessible through a command sequence,
64words for the Factory Secured Silicon Sector and
64words for the Customer Secured Silicon Sector.
„ Sector Architecture

„ WS128J : 84-ball (8 mm x 11.6 mm) FBGA package,
WS064J : 80-ball (7 mm x 9 mm) FBGA package
„ Cyclling Endurance : 1,000,000 cycles per sector
typical
„ Data retention : 20-years typical
Performance Characteristics
„ Read access times at 80/66 MHz
— Synchronous latency of 71/56 ns (at 30 pF)
— Asynchronous random access times of 55/55 ns (at
30 pF)
„ Power dissipation (typical values, C_L = 30 pF)
— Burst Mode Read: 18 mA @ 80Mhz
— Simultaneous Operation: 60 mA @ 80Mhz
— Program/Erase: 15 mA
— Standby mode: 0.2 µA
Hardware Features
„ Handshaking feature available
— Provides host system with minimum possible latency
by monitoring RDY
„ Hardware reset input (RESET#)
— Hardware method to reset the device for reading
array data
„ WP# input
— Write protect (WP#) function allows protection of
four outermost boot sectors, regardless of sector
protect status
„ 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
„ ACC input: Acceleration function reduces
programming time; all sectors locked when ACC =
V_IL
„ CMOS compatible inputs, CMOS compatible outputs
„ Low V_CC write inhibit
Software Features
„ Supports Common Flash Memory Interface (CFI)
„ Software command set compatible with JEDEC
42.4 standards
— Backwards compatible with Am29BDS, Am29BDD,
Am29BL, and MBM29BS families
„ Data# Polling and toggle bits
— Provides a software method of detecting program
and erase operation completion
„ Erase Suspend/Resume
— Suspends an erase operation to read data from, or
program data to, a sector that is not being erased,
then resumes the erase operation
„ Unlock Bypass Program command
— Reduces overall programming time when issuing
multiple program command sequences
