| CM1220 4 and 8-Channel ESD Protection Arrays in CSP Features * * * * * * * * 4 and 8 channels of ESD protection OptiGuardTM 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 Product Description California Micro Devices' CM1220 ESD protection arrays are available in four and eight channel configurations. Each ESD channel features a nominal capacitance 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 protection for sensitive electronic components that may be subjected to electrostatic discharge (ESD). These diodes safely dissipate ESD strikes of 15kV, exceeding 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 discharges 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 easyto-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 OptiGuardTM coating for improved reliability at assembly. The CM1220 is available in a space-saving, low-profile Chip Scale Packages with optional lead-free finishing. 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 Electrical Schematic ESD_1 ESD_2 ESD_3 ESD_4 C1 C3 A1 A3 ESD_1 ESD_2 ESD_3 ESD_4 ESD_5 ESD_6 ESD_7 ESD_8 A1 A3 A5 A7 C1 C3 C5 C7 B2 GND B2, B6 GND CM1220-04 CM1220-08 (c) 2006 California Micro Devices Corp.
