ADVANCE INFORMATION

Am29BDS640G

64 Megabit (4 M x 16-Bit)

CMOS 1.8 Volt-only Simultaneous Read/Write, Burst Mode Flash Memory

DISTINCTIVE CHARACTERISTICS

■ Power dissipation (typical values, C_L= 30 pF)

— Burst Mode Read: 10 mA

ARCHITECTURAL ADVANTAGES

■ Single 1.8 volt read, program and erase (1.65 to 1.95

— Simultaneous Operation: 25 mA

— Program/Erase: 15 mA

volt)

■ Manufactured on 0.17 µm process technology

■ Enhanced VersatileIO™ (V_IO) Feature

— Standby mode: 0.2 µA

— Device generates data output voltages and tolerates

data input voltages as determined by the voltage on

the V_IOpin

HARDWARE FEATURES

■ Sector Protection

— Software command sector locking

— 1.8V and 3V compatible I/O signals

■ Handshaking feature available

■ Simultaneous Read/Write operation

— Provides host system with minimum possible latency

by monitoring RDY

— Data can be continuously read from one bank while

executing erase/program functions in other bank

■ Hardware reset input (RESET#)

— Zero latency between read and write operations

— Four bank architecture: 16Mb/16Mb/16Mb/16Mb

— Hardware method to reset the device for reading array

data

■ Programmable Burst Interface

■ WP# input

— 2 Modes of Burst Read Operation

— Linear Burst: 8, 16, and 32 words with wrap-around

— Continuous Sequential Burst

— Write protect (WP#) function protects sectors 0 and 1

(bottom boot), or sectors 132 and 133 (top boot),

regardless of sector protect status

■ Sector Architecture

■ ACC input: Acceleration function reduces

programming time; all sectors locked when ACC = V_IL

— Eight 8 Kword sectors and one hundred twenty-six 32

Kword sectors

■ CMOS compatible inputs, CMOS compatible outputs

■ Low V_CCwrite inhibit

— Banks A and D each contain four 8 Kword sectors

and thirty-one 32 Kword sectors; Banks B and C

each contain thirty-two 32 Kword sectors

SOFTWARE FEATURES

— Eight 8 Kword boot sectors, four at the top of the

address range, and four at the bottom of the address

range

■ Supports Common Flash Memory Interface (CFI)

■ Software command set compatible with JEDEC 42.4

standards

■ Minimum 1 million erase cycle guarantee per sector

■ 20-year data retention at 125°C

— Backwards compatible with Am29F and Am29LV

families

— Reliable operation for the life of the system

■ Data# Polling and toggle bits

■ 80-ball FBGA package

— Provides a software method of detecting program

and erase operation completion

PERFORMANCE CHARCTERISTICS

■ Erase Suspend/Resume

■ Read access times at 54/40 MHz

— Suspends an erase operation to read data from, or

program data to, a sector that is not being erased,

then resumes the erase operation

— Burst access times of 13.5/20 ns @ 30 pF at

industrial temperature range

— Asynchronous random access times of 70 ns (at 30

pF)

■ Unlock Bypass Program command

— Reduces overall programming time when issuing

multiple program command sequences

— Synchronous latency of 87.5/95 ns with 1.8 V V_IO, and

88.0/95 ns with 3.0 V V_IO(at 30 pF)
