Closed loop air control is the primary function of air-conditioning/heating systems in automobiles.
4.15.1 Primary System considerations:
The COP8SAA7 features suited for this application include:
The COP8SAA7 based Closed Loop Temperature control system, shown in Figure 4-22,
performs the following:
• Low component cost
• Low power
• Small physical size
• Low EMI
• 16-bit PWM timer
• Enhanced outputs for LED and LCD display drives
• Additional hardware interrupts
• High-current programmable outputs
• Software trap interrupts
• Schmitt trigger inputs
• MICROWIRE/PLUS
• Measures the user-set potentiometer with a simple R/D converter
• Measures the actual temperature with a successive approximation A/D conversion
• Controls the air mix motor speed with a PWM timer
• Reads the keyboard with standard keyboard scanning routines
• Controls the LED driver, solenoid driver (for A/C) and EEPROM through the MI-
using the PWM timer
CROWIRE/PLUS serial interface.
