MPC8241 Integrated Processor Hardware Specifications
MOTOROLA
Features
– Low-voltage TTL logic (LVTTL) interfaces
– 272 Mbytes of base and extended ROM/Flash/Port X space
– Base ROM space supports 8-bit data path or same size as the SDRAM data path (32- or
64-bit)
– Extended ROM space supports 8-, 16-, 32-bit gathering data path, 32- or 64-bit (wide) data
path
– Port X: 8-, 16-, 32-, or 64-bit general-purpose I/O port using ROM controller interface with
programmable address strobe timing, data ready input signal (DRDY), and 4 chip selects
— 32-bit PCI interface
Operates up to 66 MHz
– PCI 2.2-compatible
– PCI 5.0-V tolerance
– Support for dual address cycle (DAC) for 64-bit PCI addressing (master only)
– Support for PCI locked accesses to memory
– Support for accesses to PCI memory, I/O, and configuration spaces
– Selectable big- or little-endian operation
– Store gathering of processor-to-PCI write and PCI-to-memory write accesses
– Memory prefetching of PCI read accesses
– Selectable hardware-enforced coherency
– PCI bus arbitration unit (five request/grant pairs)
– PCI agent mode capability
– Address translation with two inbound and outbound units (ATU)
– Some internal configuration registers accessible from PCI
— Two-channel integrated DMA controller (writes to ROM/Port X not supported)
– Supports direct mode or chaining mode (automatic linking of DMA transfers)
– Supports scatter gathering—read or write discontinuous memory
– 64-byte transfer queue per channel
– Interrupt on completed segment, chain, and error
– Local-to-local memory
– PCI-to-PCI memory
– Local-to-PCI memory
– PCI memory-to-local memory
— Message unit
– Two doorbell registers
– Two inbound and two outbound messaging registers
–I2O message interface
—I2C controller with full master/slave support that accepts broadcast messages
— Programmable interrupt controller (PIC)
– Five hardware interrupts (IRQs) or 16 serial interrupts
– Four programmable timers with cascade
— Two (dual) universal asynchronous receiver/transmitters (UARTs)
