MITSUBISHI MICROCOMPUTERS  
3802 Group  
SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER  
Programmable input/output ports ............................................. 56  
DESCRIPTION  
Interrupts .................................................. 16 sources, 16 vectors  
The 3802 group is the 8-bit microcomputer based on the 740 fam-  
Timers ............................................................................. 8 bit 4  
ily core technology.  
Serial I/O1 .................... 8-bit 1 (UART or Clock-synchronized)  
The 3802 group is designed for controlling systems that require  
analog signal processing and include two serial I/O functions, A-D  
converters, and D-A converters.  
Serial I/O2 .................................... 8-bit 1 (Clock-synchronized)  
PWM................................................................................ 8-bit 1  
A-D converter .................................................. 8-bit 8 channels  
The various microcomputers in the 3802 group include variations  
of internal memory size and packaging. For details, refer to the  
section on part numbering.  
D-A converter .................................................. 8-bit 2 channels  
Clock generating circuit ....................... Internal feedback resistor  
(connect to external ceramic resonator or quartz-crystal oscillator)  
For details on availability of microcomputers in the 3802 group, re-  
fer to the section on group expansion.  
Power source voltage ..................................................3.0 to 5.5 V  
(Extended operating temperature version : 4.0 to 5.5 V)  
Power dissipation ............................................................... 32 mW  
FEATURES  
Memory expansion possible  
Basic machine-language instructions....................................... 71  
Operating temperature range .................................... –20 to 85°C  
The minimum instruction execution time ............................ 0.5 µs  
(Extended operating temperature version : –40 to 85°C)  
(at 8 MHz oscillation frequency)  
Memory size  
APPLICATIONS  
Office automation, VCRs, tuners, musical instruments, cameras,  
ROM .................................................................. 8 K to 32 K bytes  
RAM ................................................................. 384 to 1024 bytes  
air conditioners, etc.
