Fast Read Performance
- 200ns Maximum Access Time
It is based on Intel MLC, Strata Flash memoriesꢀ Cards
are based on the J3 families of memory components:
built with: 28F128J3, 28F640J3, 28F320J3

Based on MLC J3 Strata Flash Components
Common Flash Interface (CFI) compliant
Erase sector size: 2x 128kB
These flash devices support the Common Flash Inter-
face (CFI) programming algorithm, a standard that al-
lows system level software to evaluate the flash con-
figuration, electrical characteristic, programming param-
eters and supported functionsꢀ CFI is intended to sup-
port future upgrades with universal programming algo-
rithms, so there is no longer a need for continued pro-
gramming software modification and updatesꢀ Systems
should be able to recognize and support all devices to
allow universal expansion/upgrade pathꢀ
High Performance Random Writes
- 6µs Typical per Byte Write Time, using 32Byte

Automated Write and Erase Algorithms
High Write/Erase Endurance:
100,000 Write/Erase Cycles
Low Power Consumption
The symmetrically blocked architecture and single sup-
ply (universal 3ꢀ3V or 5V for CLF11 cards) operation pro-
vides a cost effective, high performance, nonvolatile stor-
age solutionꢀ The Compact Flash Card form factor of-
fers an industry standard pinout and mechanical out-
line, allowing density upgrades without system design
changesꢀ

- 150µA Standby Current
- 75mA Max Byte Write Current
Note 1:
CLF11 supports wide, universal operating voltage: 3V to 5Vꢀ
That means the card will work in 3ꢀ3V systems as well as in 5V
systemsꢀ This feature may allow easy exchange of data between
multiple and different systems and provide easy upgrade / expansion
pathꢀ
The CLF11 series is designed as a simple x16 linear
array of Flash devicesꢀ Two Flash devices provide the
lower and upper bytes for the 16 bit accessꢀ (See Func-
tional Truth Table on page 5)
WEDCs standard cards are shipped with blank hous-
ings ꢀ Please contact WEDC sales representative for
