San Jose, CA, 2005-12-13 - Pericom Semiconductor Corporation
(NASDAQ: PSEM), a worldwide preferred supplier of high-speed integrated circuits and frequency control devices, today introduced a new family of
advanced analog switches created for mobile terminal applications which feature Chip Scale Packaging (CSP), very low On-Resistance, and wide voltage
ranges to address the demands of next generation portable application requirements.
Pericom's new PI5A4xxx integrated circuits (IC's) are
dual high-bandwidth SPDT and SP3T CMOS analog switches housed in ultra-small 2 x 1.5 x 0.6mm CSP packaging. Designed specifically for the mobile
market, these small footprint switches are being used for multi-band functions, polyphonic ring tones (MIDI), hands-free functions, FM radio, MP3/MP4
players, and memo recorder applications.
"The convergence of more features and connectivity into increasingly smaller cell phones and other
mobile terminals is driving the demand for analog switches in the smallest available packages. Even with the smallest die, the plastic packaging form factor
had been the limiting aspect to offering smaller footprints for PC boards," explained Shaf Rahman, Pericom Marketing Director. "Understanding this
constraint, Pericom's micro-coated CSP packages, with a solder bump pitch of 0.5mm for easy handling, have eliminated the plastic housing around the
die. Combining the low R-On (0.5-ohm), wide voltage ranges (1.65V to 5.5V), and small package, have allowed us to obtain major design wins with several
top mobile terminal manufacturers," continued Rahman.
New Products:
- PI5A4684: Low Voltage Dual SPDT Analog
Switch, 2:1 Mux/DeMux Bus Switch
