Ethernet Connectivity Solutions Block Diagram

Zilog’s eZ80AcclaimPlus! ™ Ethernet Zdots® Single Board Computers (SBCs) deliver a complete 10/100 Base-T Ethernet solution including an RFC compliant TCP/ IP Stack and RTOS. The flexibility provided by the RTOS allows the SBC to be used as the main application processor in addition to providing Ethernet connectivity.

The MCU is a 50MHz eZ80F91 which features an integrated Ethernet MAC and internal Dual Ported RAM which is supported by single cycle DMA to ensure Ethernet traffic does not compete with processor bus band width.16 KB of internal RAM is available of which 8KB is used for the Ethernet MAC.

ZTP is a preemptive, multi-tasking RTOS integrated with an RFC compliant TCP/ IP protocol software stack optimized for embedded eZ80F91 applications. The modular design of ZTP enables the user to include only the library objects required by the application minimizing the memory footprint.
