Timing Conditions

Unless specified otherwise, the following conditions are true for all timing measurements.

•TA = 0 to 70° C

• CVDD = VDD_PLL = 1.8V

•RVDD = 3.3 V

• All grounds = 0 V

• Logic 0 = 0 V, Logic 1 = 3.3 V

• Output loading = 50 pF

• Timing reference levels = 1.5 V

• The Processor Bus Clock (HCLK) is programmable and is set by the user. The frequency is typically between

33 MHz and 100 MHz (92 MHz for industrial conditions).
