Mixed Signal Programmable Logic

Silego

The Leader in Configurable Mixed Signal ICs

Silego designs and sells highly configurable power, logic, and timing mixed signal IC products referred to as CMICs (Configurable Mixed-signal IC Products). The CMIC products integrate medium precision analog components, discrete digital logic, and passive components into highly configurable small, easy to use, low cost ICs. CMIC products provide customers the benefits of reduced system parts count, lower power consumption, less board space and reduced BOM costs.

GreenPAK4

Silego's GreenPAK4 is a highly versatile, NVM Programmable Mixed-signal Matrix designed to easily implement differentiating features and functions into already highly integrated designs while minimizing component count, board space, and power consumption. GPAK4 comprises the best analog and digital resources from previous generations with expanded functionality and a few new additions, such as the hardware reset pin and Digital to Analog Converter (DAC), all in a tiny package.

  • Cost effective one-time NVM programmable Mixed Signal Matrix Device
  • Useful for integrating many discrete ICs into a single device
  • User configured and can be programmed in minutes
  • Includes complete design tools

GreenFET3

Silego's GreenFET3 is the smallest complete load switch with Rds(ON) <7.8 mohm.

  • 1.5x2mm FC-TDFN-8 package
  • 1uA Sleep and 70uA Active Mode power consumption
  • External capacitor to adjust VS ramp rate
  • VDD 2.5 to 5.5V
  • Internal charge pump

GreenCLK3

Silego's GreenCLK3 is a silicon-based 32.768 kHz crystal replacement technology. Using a single MHz reference (crystal, XO, or TCXO), the GreenCLK3 generates a cost-effective timing solution with a single 32.768 kHz clock output and a single MHz clock output.
 
Replacing 32.768 kHz RTC with GCLK3 reduces component count, board space, and BOM cost.
 
  • Ultra-Low Power Consumption
     
    • 0.8 µA for 32.768 kHz in Hibernate Mode
    • 0.8 mA for MHz & 32.768 kHz in Active Mode
  • Stability Over Temperature for 32.768 kHz Applications
    • ±15 PPM 32.768 kHz clock stability over -40C˚ to 85C˚ range
  • Integrated On-chip Load Capacitors
  • Tiny Package Size and Layout Footprint
     
    • 1.0 x 1.45 x 0.3mm, 0.5mm pitch 6-pin ETDFN
    • 1.0 x 1.6 x 0.55mm, 0.4mm pitch 8-pin STDFN
    • 1.0 x 2.0 x 0.55mm, 0.4mm pitch 10-pin STDFN
    • Lo-Z package option available for 0.3mm MAX height
    • 5.2 mm2 overall footprint with 1612 size MHz crystal
