California Micro Devices Raises Performance Bar for ESD Protection
New Ultra Low Capacitance PicoGuard™ CM1215 and CM1216 Devices Offer
Industry’s Highest Levels of ESD Protection

MILPITAS, Calif., -- July 1, 2005 -- California Micro Devices (NASDAQ: CAMD) today announced the availability of its newest PicoGuard™ ultra low capacitance diode arrays for electrostatic discharge (ESD) protection for digital consumer and computing applications. The CM1215 and CM1216 are the industry’s first low capacitance devices to offer ±15kV of contact ESD protection, exceeding IEC61000-4-2 level 4 standards. Designers of digital consumer and computing applications such as digital TVs, set top boxes, digital still cameras, MP3 players and notebook PCs are increasingly seeking solutions that can offer ESD protection at levels greater than ±8kV. The ultra low 1.6 pF capacitance levels of the CM1215 and CM1216 make them ideal solutions for designers seeking higher levels of ESD protection for high speed ports such as USB 2.0, IEEE 1394 Firewire, DVI, HDMI and Serial ATA that are commonly found in these applications.

Key Features
The CM1215 and CM1216 diode arrays offer the highest levels of ESD protection, the lowest clamping voltages and the lowest dynamic resistance of any low capacitance diode array, providing the highest level of protection to sensitive ICs. The low capacitance, combined with good matching and low crosstalk, provide excellent signal integrity for high speed data lines.

Key Feature	CM1215 and CM1216	Typical Competitor Diode Array	Benefit
Highest ESD Rating (IEC61000-4-2)	15kV contact	8kV contact	Protects against higher levels of ESD strikes
Lowest Clamping Voltage	9V	12V	Lower clamping voltage reduces soft and hard errors
Lowest Dynamic Resistance	0.6 Ohm	1.4 Ohm	Reduces current and voltage seen by IC during strike, reducing soft and hard errors
Ultra-low Capacitance (I/O to GND)	1.6 pF	3.0 pF	Improves signal integrity on high speed ports
Lowest Mutual (I/O to I/O) Capacitance	0.13 pF	1.5 pF	Minimizes crosstalk for improved signal integrity
Closely matched Capacitance	0.04 pF	not specified	Minimizes signal skew and EMI
Reliability/Endurance	> 1000 strikes	not specified	Survives multiple strikes typical of consumer applications

The CM1215 is available in configurations of 1, 2, and 4 channels of ESD protection, integrating a pair of low capacitance rail clamp diodes for each line. The CM1216 is available in configurations of 6 and 8 channels and features a pair of low capacitance diodes as well as an integrated Zener diode for improved ESD performance. These products are offered in packages that are pin compatible with the popular PicoGuard™ CM1213 family, which provides ±8kV of contact protection, allowing customers to upgrade to higher levels of protection without changing their existing layouts.

Pricing and Availability
The CM1215 and CM1216 are currently in production, and are priced between $0.27 and $0.67 each at 1,000 units depending on number of channels. Lead free versions are available.
