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.
FEATURES
32k-Word/64k-Byte uniform sector architecture
– Total 128 uniform sectors
– Total 127 uniform sectors + eight 4kWord/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
