MPC8640 and MPC8640D Integrated Host Processor Hardware Specifications, Rev. 1

Freescale Semiconductor

Electrical Characteristics

— Support for PCI-Express message-shared interrupts (MSIs)

•

Local bus controller (LBC)

— Multiplexed 32-bit address and data operating at up to 125 MHz

— Eight chip selects support eight external slaves

•

Integrated DMA controller

— Four-channel controller

— All channels accessible by both the local and the remote masters

— Supports transfers to or from any local memory or I/O port

— Ability to start and flow control each DMA channel from external 3-pin interface

•

Device performance monitor

— Supports eight 32-bit counters that count the occurrence of selected events

— Ability to count up to 512 counter-specific events

— Supports 64 reference events that can be counted on any of the 8 counters

— Supports duration and quantity threshold counting

— Burstiness feature that permits counting of burst events with a programmable time between

bursts

— Triggering and chaining capability

— Ability to generate an interrupt on overflow

•

Dual I2C controllers

— Two-wire interface

— Multiple master support

— Master or slave I2C mode support

— On-chip digital filtering rejects spikes on the bus

•

Boot sequencer

— Optionally loads configuration data from serial ROM at reset via the I2C interface

— Can be used to initialize configuration registers and/or memory

— Supports extended I2C addressing mode

— Data integrity checked with preamble signature and CRC

•

DUART

— Two 4-wire interfaces (SIN, SOUT, RTS, CTS)

— Programming model compatible with the original 16450 UART and the PC16550D

•

IEEE 1149.1-compliant, JTAG boundary scan

•

Available as 1023 pin Hi-CTE flip chip ceramic ball grid array (FC-CBGA)
