AM186ER-25KCW AMD [Advanced Micro Devices], AM186ER-25KCW Datasheet - Page 73

• Manufacturer Part Number: AM186ER-25KCW
• Description: High-Performance, 80C186- and 80C188-Compatible, 16-Bit Embedded Microcontrollers with RAM
• Manufacturer: AMD [Advanced Micro Devices]

Switching Characteristics over Commercial and Industrial Operating Ranges
Write Cycle (25 MHz and 33 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.
