description

The TFB2002BI I/O controller (IOC) is a member of the Texas Instruments Futurebus+ (FB+) chip set. This chip set provides a highly integrated approach to the Futurebus+ interface that reduces new-product design time, allows more functionality per circuit board, improves overall interface reliability, and reduces end-user down time through built-in test capabilities. The Futurebus+ chip set is capable of supporting 32- or 64-bit data widths in any combination on both the host-bus interface (HIF) and Futurebus+. The address width is programmable to be 32 bits or 36 bits (with either data width).

The TFB2002BI contains the control logic necessary to translate Futurebus+ transactions into host bus transactions and vice versa. It contains a high-speed Futurebus+ handshake controller, a synchronous host bus controller, and reset-type determination logic.

When combined with a TFB2022A Futurebus+ data path unit (DPU), the TFB2002BI provides a complete 64-bit-wide interface to the Futurebus+. The TFB2002BI provides the necessary control logic for the data path unit to provide a complete interface to the Futurebus+ for a Profile-B-compliant module. It may also be used on I/O or memory modules in a cache-coherent system.

The TFB2002BI is offered in a 208-pin plastic quad flat package (PPM). The TFB2002BI is characterized for operation over the industrial temperature range of -20°C to 85°C
