AM186ER-25KCW AMD [Advanced Micro Devices], AM186ER-25KCW Datasheet - Page 66

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

Table 16 shows typical maximum ambient temperatures in degrees Centigrade for a TQFP package used with a
4-layer to 6-layer board. The typical ambient temperatures are based on a 100-degree Centigrade maximum case
temperature. Figure 21 illustrates the typical temperatures in Table 16.
