Clock Ð 32.7 kHz crystal oscillator,

Microprocessor support circuit (Reset Control),

Flash Memory (4 megabytes),

DRAM (4 megabytes)

Static RAM (512 Kbytes, buffered),

System Control ASIC.

Real-time clock/calendar (RTC),

Asynchronous serial communications interface UART (SCC/SMC
ports),

Ethernet SCC 1 (ETHERNET port),

Noninvasive blood pressure interface,

Alarm Light interface

Analog output 10-bit DAC (ECG),

Stereo sound generator, audio amplifier and speaker interface,

Key pad (TRIM KNOB and push-buttons) interface,

Integrated video processing circuit which develops waveform and
text data for display,

High frequency isolation region, DAS interface and power supply
interface.
