76 / 98 page ![]() 76 Am186/188EM and Am186/188EMLV Microcontrollers PRELIMINA R Y SWITCHING CHARACTERISTICS over COMMERCIAL operating range PSRAM Refresh Cycle (33 MHz and 40 MHz) Note: All timing parameters are measured at 1.5 V with 50 pF loading on CLKOUTA unless otherwise noted. All output test conditions are with CL = 50 pF. For switching tests, VIL = 0.45 V and VIH = 2.4 V, except at X1 where VIH = VCC – 0.5 V. a Equal loading on referenced pins.
