AM186ES Advanced Micro Devices, AM186ES Datasheet - Page 78

• 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
PSRAM Read 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 If either spec 2 or spec 59 is met with respect to data hold time, the part will function correctly.
