Operating Characteristics
Microprocessor
Compatibility
Motorola MC68306 microprocessor
Microprocessor
Package
132-pin QFP
The HP E2456A does not support the 144-pin TQFP processor package.
Accessories
Required
HP E3417A generic PGA to 132-pin QFP probe adapter.
Maximum Clock
Speed
16.67 MHz Clockout (8.33 MHz ~AS rate).
Power Requirements 100 mA at +5 Vdc maximum, supplied by the logic analyzer.
Probes Required Seven 16-channel pods are available. Three are required for inverse
assembly with state analysis.
Signal Line Loading Loading when using only pods P1, P3, and P4 is 20 pF in parallel with
100 kOhm on all lines (except 10 pF on EXTAL and XTAL). Connecting
additional pods may increase loading on certain signals.
Environmental
Temperature
Operating
Nonoperating
0 to 55 degrees C (+32 to +131 degrees F)
-40 to +75 degrees C (-40 to +167 degrees F)
Altitude Operating
Nonoperating
4,600 m (15,000 ft)
15,300 m (50,000 ft)
Humidity Up to 90% noncondensing. Avoid sudden, extreme temperature
changes which could cause condensation within the instrument.
