LC651104N

LC651104N is a kind of single-chip 4-bit microcomputer. It includes an eight-channel, 8-bit A/D converter. The typical applications include audio equipment (tape deck, player, etc), office equipment, communications equipment, car equipment, home appliances as well as circuits so far formed with the standard logic circuits and applications where the number of controls is small.

There are some features of LC651104N as follows. First is CMOS technology for a low-power operation (with instruction-controlled standby function). The second is wide operating voltage range from 2.5 V to 6.0 V. Then is instruction cycle time of 0.92s. Next is on-chip serial I/O port. The fifth is stack level which is 8 levels (common wide interrupt). The sixth is timer which is 4-bit prescaler + 8-bit programmable timer. The seventh is clock oscillation option selectable for your intended system. The eighth is flexible I/O port. The last one is burst pulse (64*cycle time) output function.

What comes next is the absolute maximum ratings of LC651104N at Ta=25, VSS=0 V. The VDD max (maximum supply voltage) is from -0.3 to +7.0 V for VDD pin. The VO (output voltage) is allowable up to voltage generated for OSC2 pin. The VI(1) (input voltage) is from -0.3 to VDD+0.3 V for OSC1 pin. The VI(2) (input voltage) is from -0.3 to VDD+0.3 V for pins TEST, RES, AV+, AV-. The IOP (peak output current) is from -2 to +20 mA for I/O port. The IOA (average output current) is -2 to +20 mA per pin over the period of 100 ms. The Pd max (allowable power dissipation) is 250 mW at Ta=-40 to +85 for DIP package and 150 mW for MFP package. The Topg (operating temperature) is from -40 to +85. The Tstg (storage temperature) is from -55 to +125.
