RT9178-2HCB Features:
The RT9178-2HCB provides an on-chip MIB statistics register to collect, receive, and tran*it statistics for each port. Additionally it provides direct hardware support for the EtherLike MIB, Bridge MIB, MIB II (interfaces) and the first four groups of the RMON MIB. All nine groups of RMON can be supported by using additional capabilities, such as port mirroring/snooping, together with an external microcontroller to process some MIB attributes. The MIB registers can be accessed through the serial management port by an external microcontroller.
RT9178-2HCB(Absolute) Maximum Ratings:
The Intersil RT9178-2HCBRH is a radiation hardened 8-bit input/ output port designed for use with the HS-80C85RH radiation hardened microprocessor. It is manufactured using a self- aligned, junction-isolated EPI-CMOS process and features three-state output buffers and device selection and control logic. A service request ?ip-?op is included for the generation and control of interrupts to the microprocessor. The device can be used in implement many of the peripheral and input/output functions of a microcomputer system. The RT9178-2HCBRH is pinout- and function- compatible with industry-standard 8212 devices.
