Fig. 6.1.5-1 shows the timing diagram of each parameter.
6.2 Package
The M65727 is housed in plastic 152-pin 28mm x 28mm body HQFP.
Fig. 6.2-1 shows an overview of the package, and fig. 6.2-2 and table 6.2-1 show the pin configuration.
6.3 Thermal Management
The M65727 is designed to operate at 27MHz and 40.5MHz. When 27MHz operation, no thermal
management is required (The M65727 can operate in still air.). But, when 40.5MHz, some thermal
management is required.
The required thermal management is as follows:
· Forced air cooling by 0.5m/s air
· Forced cooling by heat sink (for example: Aluminum table : 28mm x 28mm x 2mm)
