MPC8280 PowerQUICC II Family Hardware Specifications
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-defined 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 Ratings

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.
2
Caution:
VDD/VCCSYN must not exceed VDDH by more than 0.4 V at any time, including during power-on
reset.
3
Caution:
VDDH can exceed VDD/VCCSYN by 3.3 V during power on reset by no more than 100 mSec. VDDH
should not exceed VDD/VCCSYN by more than 2.5 V during normal operation.
4
Caution:
VIN must not exceed VDDH by more than 2.5 V at any time, including during power-on reset.
