MOTOROLA
MPC8280 PowerQUICC II Family Hardware Specications
7
Operating Conditions
– Independent transmit and receive routing, frame synchronization
– Supports T1, CEPT, T1/E1, T3/E3, pulse code modulation highway, ISDN basic rate, ISDN
primary rate, Motorola interchip digital link (IDL), general circuit interface (GCI), and
user-dened TDM serial interfaces
— Eight independent baud rate generators and 20 input clock pins for supplying clocks to FCCs,
SCCs, SMCs, and serial channels
— Four independent 16-bit timers that can be interconnected as two 32-bit timers
Inverse multiplexing for ATM capabilities (IMA) (MPC8280 only).Supported by eight transfer
transmission convergence (TC) layers between the TDMs and FCC2.

Operating Conditions
Table 3 shows the maximum electrical ratings.
Table 4 lists recommended operational voltage conditions.
Table 3. Absolute Maximum Ratings1
1 Absolute maximum ratings are stress ratings only; functional operation (see Table 4) at the maximums is not guaranteed. Stress beyond those listed may affect device reliability or cause permanent damage.
