5 / 84 page MPC8541E PowerQUICC™ III Integrated Communications Processor Hardware Specifications, Rev. 4 Freescale Semiconductor 5 Overview — Four global high resolution timers/counters that can generate interrupts — Supports additional internal interrupt sources — Supports fully nested interrupt delivery — Interrupts can be routed to external pin for external processing — Interrupts can be routed to the e500 core’s standard or critical interrupt inputs — Interrupt summary registers allow fast identification of interrupt source •Two I2C controllers (one is contained within the CPM, the other is a stand-alone controller which is not part of the CPM) — 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 stand-alone 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 (RXD, TXD, RTS, CTS) — Programming model compatible with the original 16450 UART and the PC16550D • Local bus controller (LBC) — Multiplexed 32-bit address and data operating at up to 166 MHz — Eight chip selects support eight external slaves — Up to eight-beat burst transfers — The 32-, 16-, and 8-bit port sizes are controlled by an on-chip memory controller — Three protocol engines available on a per chip select basis: – General purpose chip select machine (GPCM) – Three user programmable machines (UPMs) – Dedicated single data rate SDRAM controller — Parity support — Default boot ROM chip select with configurable bus width (8-, 16-, or 32-bit) • Two Three-speed (10/100/1000)Ethernet controllers (TSECs) — Dual IEEE 802.3, 802.3u, 802.3x, 802.3z AC compliant controllers — Support for Ethernet physical interfaces: – 10/100/1000 Mbps IEEE 802.3 GMII – 10/100 Mbps IEEE 802.3 MII – 10 Mbps IEEE 802.3 MII |
