4 and 8-Channel ESD Protection Arrays in CSP
Features
• 4 and 8 channels of ESD protection
• OptiGuard™ coated for improved reliability
• ±15kV ESD protection on each channel
(IEC 61000-4-2 Level 4, contact discharge)
• ±30kV ESD protection on each channel (HBM)
• Chip Scale Package features extremely low
lead inductance for optimum ESD protection
• 5 bump, 0.960mm X 1.330mm CSP footprint
for CM1220-04
• 10 bump, 1.960mm X 1.330mm CSP footprint
for CM1220-08
• Lead-free version available
Applications
• LCD and camera datalines in mobile handsets
• I/O port protection for mobile handsets, notebook
computers, PDAs, etc.
• Keypads and buttons
• Wireless handsets
• Handheld PCs/PDAs
• LCD and camera modules
Product Description
California Micro Devices' CM1220 ESD protection
arrays are available in four and eight channel configu-
rations. Each ESD channel features a nominal capaci-
tance of 14pF making these devices ideal for
protecting high speed I/O ports and LCD and camera
data lines without significantly affecting signal integrity.
The CM1220 integrates avalanche-type ESD diodes
on every channel, providing a very high level of protec-
tion for sensitive electronic components that may be
subjected to electrostatic discharge (ESD). These
diodes safely dissipate ESD strikes of ±15kV, exceed-
ing the maximum requirement of the IEC61000-4-2
international standard. Using the MIL-STD-883
(Method 3015) specification for Human Body Model
(HBM) ESD, these devices protect for contact dis-
charges at greater than ±30kV.
These devices are particularly well-suited for portable
electronics (e.g. wireless handsets, PDAs, notebook
computers) because of their small package and easy-
to-use pin assignments. In particular, the CM1220 is
ideal for protecting high speed I/O ports and data and
control lines for the LCD display and camera interface
in mobile handsets.
These devices incorporate CMD’s OptiGuard™ coating
for improved reliability at assembly. The CM1220 is
available in a space-saving, low-profile Chip Scale
Packages with optional lead-free finishing.
