HP 64789B Emulator for the Intel 386EX Embedded Processor

The HP 64789B emulator supports the Intel 80386EX processor with real-time, no wait state emulation to 25 MHz in both real and protected modes. The emulator also fully supports the System Management Mode (SMM) operation. User selectable foreground and background monitors with dual port memory insure maximum transparency in varied operating environments.

The HP 64789B active probe implementation operates between 3.3V and 5V and has long 914 mm (36 inch) cables for easy target system access without sacrificing electrical transparency or clock speed. The probe contains a bond-out version of the microprocessor, emulation monitor, run control circuits and up to 8 Mbytes of emulation overlay memory. Extensive breakpoint capabilities provide considerable flexibility to start and stop program execution at specific locations within very complex code.

Probe Adapter for HP 64789B

HP E3417A Probe adapter for 132 pin PQFP:

The HP E3417A probe adapter connects to 132 PQFP versions of the Intel386 EX processor and converts the signals to the 13x13 PGA pattern required by the emulator probe. The probe adapter snaps on to the device under test (DUT). In addition, the adapter has four clips that slide under the DUT to secure the connection.

Connection between the female PGA pattern found on the adapter transition board and the female PGA interface on the emulator probe is accomplished with a male to male PGA header (HP Part Number 64774-87604) which is shipped with each emulator probe. For pin protection, one or more PGA sockets (HP part number 1200-1920) may be used.

[ Features ]

Emulation Features

Real-time zero wait state operation from emulation or target memory to 25 MHz.
Support 3.3V to 5.5V operation.
Active probe includes 8K of dual port emulation memory and supports up to 8 Mbytes of additional emulation overlay memory.
Demo board with both 132 PQFP and 144 TQFP versions of the 386EX included for easy performance verification.
Full symbolic debugging support for fast, easy development and debugging with HP user interface.
Supports both real and protected modes to facilitate code reuse.
Background and foreground monitors support all run control features and require minimal resources from the target system.
Breakpoints

Unlimited software breakpoints.
Four hardware execution or access breakpoints. Analyzer Features

8K, 64K or 256K analyzer trace buffer supports real-time analysis of address, data and status/control information in conjunction with instruction dequeing of the trace list.
Passive Mode Analysis operation allows emulator probe to simply replace the processor under test which helps isolate system problems from test equipment problems.
