64M-BIT 3.0-VOLT PARALLEL FLASH MEMORY WITH PAGE MODE

Winbond 

W29GL064C

1 GENERAL DESCRIPTION

The W29GL064C Parallel Flash memory provides a storage solution for embedded system

applications that require better performance, lower power consumption and higher density. This device

has a random access speed of 70 ns and a fast page access speed of 25 ns, as well as, significantly

faster program and erase times than the comparable products available on the market today. The

W29GL064C also offers special features such as Compatible Manufacturer ID that makes the device

industry standard compatible without the need to change firmware.

2 FEATURES

• 32k-Word/64k-Byte uniform sector

architecture

– Total 128 uniform sectors

– Total 127 uniform sectors + eight 4k-

Word/8k-Byte sectors

• 16-Word/32-Byte write buffer

– Reduces total program time for

multiple-word updates

• 8-Word/16-Byte page read buffer

• Secured Silicon Sector area

– Programmed and locked by the

customer or during production

– 128-word/256-byte sector for

permanent, safe identification using an

8-word/16-byte random electronic

serial number

• Enhanced Sector Protect using

Dynamic and Individual mechanisms

• Polling/Toggling methods are used to

detect the status of program and erase

operation

• Suspend and resume commands used

for program and erase operations

• More than 100,000 erase/program

cycles

• More than 20-year data retention

• Low power consumption

• Deep power down mode

• Wide temperature range

• Compatible manufacturer ID for drop-in

replacement

– No firmware change is required

• Faster Erase and Program time

– Erase is1.5x faster than industry

standard

– Program is 2x faster than industry

standard

– Allows for improved production

throughput and faster field updates

• CFI (Common Flash Interface) support

• Single 3V Read/Program/Erase (2.7 -

3.6V)

• Enhanced Variable IO control

– All input levels (address, control, and

DQ) and output levels are determined

by voltage on the EVIO input. EVIO

ranges from 1.65 to VCC

• #WP/ACC Input

– Accelerates programming time (when

VHH is applied) for greater throughput

during system production

– Protects first or last sector regardless

of sector protection settings

• Hardware reset input (#reset) resets

device

• Ready/#Busy output (RY/#BY) detects

completion of program or erase cycle

• Packages

– Uniform Sector (H/L)
