Specifications of MC68MH360EM25L

• Processor Type: M683xx 32-Bit
• Speed: 25MHz
• Voltage: 5V
• Mounting Type: Surface Mount
• Package / Case: 240-FQFP
• Lead Free Status / RoHS Status: Contains lead / RoHS non-compliant
• Features: -

For synchronous communication, the internal clock is identical to the baud rate output. To
get the desired rate, the user can select the appropriate system clock according to the fol-
lowing equation:
sync baud rate = (BRGCLK or CLK2 or CLK6)
the DIV16 bit)
For example, to get the rate of 64 kbps, the system clock can be 24.96 MHz, DIV16 = 0, and
the clock divider = 389.
