MPC8280 PowerQUICC II Family Hardware Specifications, Rev. 2

Freescale Semiconductor

Operating Conditions

– Provides management for BRI devices as general-circuit interface (GCI) controllers in

time-division-multiplexed (TDM) channels

– Transparent

– UART (low-speed operation)

— One serial peripheral interface identical to the MPC860 SPI

— One I2C controller (identical to the MPC860 I2C controller)

– Microwire compatible

– Multiple-master, single-master, and slave modes

— Up to eight TDM interfaces (four on the MPC8270)

– Supports two groups of four TDM channels for a total of eight TDMs (one group of four on

the MPC8270 and the MPC8275)

– 2,048 bytes of SI RAM

– Bit or byte resolution

– Independent transmit and receive routing, frame synchronization

– 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.

•

Transmission convergence (TC) layer (MPC8280 only)

Operating Conditions

This table shows the maximum electrical ratings.

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.
