DESCRIPTIONS
The EP100 PowerPC bus slave device is a bus interface unit designed for the PowerPC host bus. It is designed to work on any 60x compliant bus architecture.
It has two user interfaces, one for interfacing with on-chip and off-chip user logic and register and the second interface is a direct interface to external asynchronous SRAM and synchronous BURST SRAM.
FEATURES
• Fully supports PowerPC™ 60x bus protocol including PowerPC 603, 604, 740, 750 and MPC8260.
• Provide PowerPC bus device access to memory and devices on user interface.
• Direct support for standard asynchronous SRAM and synchronous BURST SRAM.
• Burst access support using conventional asynchronous SRAM.
• Additional back-end interface bus for on-chip and off-chip logic and register access.
• Back-end interface supports user device with various wait states.
• Burst access support including MPC8260 extended transfer size.
• Write buffer supports write posting for the back-end bus interface.
• Handles separate address bus and data bus tenure.
• Supports PowerPC address pipeline for improve performance.
• Supports address bus retry generated by other external device.
• Qualified address data bus grant through the use of bus busy signals.
• Designed for ASIC and programmable logic device implementations in various system environments.
• Fully static design with edge triggered flip-flops.
• Optimized for Actel SX-A, RTSX-S, AX, and APA product families.
