TSPC106AVGU66CG

Controllers Overview

The TSPC106AVGU66CG is a high-performance PCI bus controller manufactured by Microchip Technology. It provides an integrated interface between a 60x processor, secondary cache, and the PCI bus. The device supports processor bus frequencies up to 66 MHz and 83.3 MHz with a 64-bit data bus and 32-bit address bus. It features L2 cache control for 256-Kbyte, 512-Kbyte, or 1-Mbyte sizes and complies with PCI Specification Revision 2.1. The component operates at VCC = 3.3V ± 5% and includes JTAG boundary-scan support. It is available in a 303-ball CBGA package.

Controllers Feature Summary
