4.0 Electrical and Mechanical
Specifications
This chapter discusses the electrical specifications of the CN8223, such as power
requirements, temperature ranges, DC characteristics and timing. A mechanical
drawing is included.
4.1 Power Requirements and Temperature
Range
The CN8223 meets all specifications over a temperature range of –40 °C to 85 °C
and input voltage range of 4.75 V to 5.25 V. The maximum current required for
the circuit in operation is estimated at 300 mA (at 155 MHz). The thermal
characteristics of the 160-pin PQFP are 51.9 °C for θJA (Still Air) and 37.1 °C for
θJA (Air Flow 400 LFPM).
