2 Hardware Structure of the EB 200P
2.1 ERTEC 200P
2.1.1 Function Overview
Refer to documents /1/ and /2/ for a detailed function description of the ERTEC 200P.
In this manual, only the main components are described briefly and represented in a block diagram.
The following four AHB masters are integrated in the ERTEC 200P:
ARM926EJ-S with trace/debug port and high-performance interrupt controllers
PNIP with 64 Kbytes of K-RAM for real-time Ethernet communication
External host processor on the XHIF interface
32-channel DMA controller
The following I/O blocks are available to the masters:
External memory controller (EMC) with SDRAM and SRAM controller
Two Ethernet interfaces with integrated MII PHYs
Blocks connected to APB bus
96-bit GPIO
4x UART
2x SPI
3x I
2
C
6 timers
F-timer
2x Watchdog
Boot ROM
System Control
Peripherie Interface
I-Filter
The multi-layer AHB bus system enables a largely independent operation of the masters. Internal arbitration logic
prevents access conflicts if multiple masters want to access the same I/O block. The function groups of the ERTEC
200P are shown in block diagram. For block diagram please refer to /1/
