ꢀ2 clock generating circuits  
DESCRIPTION  
(connect to external ceramic resonator or quartz-crystal oscillator)  
ꢀPower source voltage  
The 3822 group is the 8-bit microcomputer based on the 740 fam-  
ily core technology.  
In high-speed mode .................................................. 4.0 to 5.5 V  
In middle-speed mode ............................................... 2.5 to 5.5 V  
(Extended operating temperature version:  
2.0 to 5.5 V, Ta= – 20 to 85°C  
The 3822 group has the LCD drive control circuit, an 8-channel  
A-D converter, and a serial I/O as additional functions.  
The various microcomputers in the 3822 group include variations  
of internal memory size and packaging. For details, refer to the  
section on part numbering.  
3.0 to 5.5 V, Ta= – 40 to – 20°C)  
(One time PROM version: 2.5 to 5.5 V)  
For details on availability of microcomputers in the 3822 group, re-  
fer to the section on group expansion.  
(M version: 2.2 to 5.5 V)  
(H version: 2.0 to 5.5 V)  
In low-speed mode .................................................... 2.5 to 5.5 V
