Digital circuitry
Refer to Figure 4-9 for the following discussion on digital circuitry.
The core digital circuitry uses a Motorola 68332 microcontroller (U163) running at
16.78MHz. The memory configuration includes a flash EEPROM (U168) and a RAM (U160).
Flash ROM support allows internal firmware upgrades using either the serial or GPIB port for
downloading new firmware. All calibration constants and the saved setups are stored in a sepa-
rate serial EEPROM (U141).
External communication is provided via GPIB and serial interfaces. A 9914 GPIB IEEE-488
standard interface IC (U167) is used for the GPIB, and a U166 provides the voltage conversion
for the RS-232 port. U164 provides interfacing for the Digital I/O port.
