H HP E2411C and HP E5344A Intel80486* Preprocessor Interface For use with HP logic analyzers The Hewlett-Packard E2411C preprocessor supports the Intel486DX, DX2, DX4, 486SX, 486SL Enhanced, and 487SX, as well as the OverDrive for the 486DX chip. The preprocessor interface provides an electrical 0.8 in. ______ 20.0 mm is displayed, the data is disassembled and listed in 80486 mnemonics. The disassembler also decodes FPU instructions for target systems that use the Intel486DX and Intel487SX chips. and mechanical connection between your target system and an HP logic analyzer.

Channel-to-channel skew is 1 ns. •HP 1660-series The preprocessor allows you to improve trace readability by controlling the amount of information being sent to the analyzer. For example, you can configure the preprocessor to filter out cache invalidation cycles from the analyzer. For DMA transfers you can configure the preprocessor to send all DMA cycles, to send just one cycle which indicates a DMA transfer occurred, or to send no DMA cycles to the analyzer. Number of Probes Required Five, sixteen-channel probes are required for complete state disassembly. Two additional pods can be used to monitor AHOLD, INTR, RESET, FLUSH#, BREQ, HOLD, A20M#, PLOCK, PWT, ADS#, RDY#, BRDY#, CACHE#, BLEN#, HITM#, HIT#, UP#, BRDYC#, INV, R/S#, PRDY, NMI, INIT, IGNNE#, FERR#, ETRDY#, ETADS#, SMIACT#, SMI#, PCHK#, EWBE#, and WB/WT#. The following types of instructions can be selected to be displayed or suppressed: unexecuted prefetches, jumps, calls/returns, and other instructions. In addition, the following operations can be displayed or suppressed: memory read/writes, I/O read/writes, special cycles, and interrupt acknowledge cycles. Also, FPU instructions are decoded in the display. Termination Adapters Required None. All pods are terminated on the preprocessor. † Emulation Technology, Inc. 2344 Walsh Ave. Bldg F Santa Clara, CA 95051 Ph. 408-982-0660 Fax: 408-982-0664 †† Maximum bus clock rate is 33 MHz 3 HP E5344A CQFP/PQFP Adapter A CQFP/PQFP adapter is available from HP that is designed to support the Intel80486 microprocessor in a 208-pin CQFP/PQFP package. This product includes a PGA transition board (shown in figure 2) that allows an HP E2411C preprocessor with a PGA connector to be plugged directly onto the PGA socket of the transition board. An overview of the HP E5344A physical dimensions is provided in figure 3. For complete dimensions and specifications, refer to the HP CQFP/PQFP probe adapter technical data sheet, pub number 5963-9497E.
