AM186ES Advanced Micro Devices, AM186ES Datasheet - Page 71

• Manufacturer Part Number: AM186ES
• Description: microcontrollers provide a low-cost/ high-performance solution for embedded system designers who wish to use the x86 architecture.
• Manufacturer: Advanced Micro Devices

Switching Characteristics over Commercial and Industrial Operating Ranges
Read Cycle (40 MHz and 50 MHz)
Notes:
All timing parameters are measured at V
output test conditions are with C
a Testing is performed with equal loading on referenced pins.
b This parameter applies to the DEN, INTA1–INTA0, WR, WHB, and WLB signals.
