MPC8280 PowerQUICC II Family Hardware Specifications, Rev. 1.8
Freescale Semiconductor
7
Operating Conditions
– Supports T1, CEPT, T1/E1, T3/E3, pulse code modulation highway, ISDN basic rate, ISDN primary
rate, Freescale 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
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.

Caution: VDD/VCCSYN must not exceed VDDH by more than 0.4 V during normal operation. It is recommended
that VDD/VCCSYN should be raised before or simultaneous with VDDH during power-on reset. VDD/VCCSYN may
exceed VDDH by more than 0.4 V during power-on reset for no more than 100 ms.
