HP E2447AB Motorola 68EC000 Preprocessor Interface

Product Summary

The Motorola 68EC000 preprocessor interface provides an easy way to connect your Motorola 68EC000 microprocessor to a HP logic analyzer. All necessary clocks are passed through the preprocessor to the logic analyzer, ensuring that the data is captured at the correct time.

Product Features

• Instructions that are pre-fetched, but not executed are marked in the trace display.
• Unbuffered timing analysis for all signals is provided.
• When using PLCC versions of the chip, probing points to take parametric measurements are provided.
• Operations displayed:
  • User Data Read/Write
  • User Program Read
  • Supervisor Read/Write
  • Supervisor Program Read
  • Interrupt Acknowledge

Product Specifications

Microprocessor Compatibility
68EC000 69-pin PLCC through 16.7 MHz

Logic Analyzers Supported
HP 1650, 1652, 1654
HP 16510B, 16511B
HP 16554A, 16555A, 16556A

Pods Required
Four pods allow timing measurement of all processor signals.
Note: Each preprocessor has three connectors available for state 
analysis with additional connectors for timing analysis for all 
signals.  For disassembly, three pods must be used.  All signals used 
in disassembly can be double probed for state and timing analysis.

Adapters
All connectors are terminated on the preprocessor; no termination 
adapters are required.  For timing analysis, one termination adapter 
is required per pod.

Adapters available:
PLCC/PGA IC Chip Carrier Socket
PGA/PLCC Adapter

Signal Line Loading
50 kOhms plus 22 pF on USD
100 kOhms plus 18 pF on all other lines
