4-bit single-chip CMOS microcontroller for small-scale control applications
The LC651306A, LC651304A, LC651302A, LC651301A belong to our 4-bit single-chip microcontroller
LC6500 series fabricated using CMOS process technology. They are ideally suited for use in small-scale control
applications. Their basic architecture and instruction set are the same. These microcontrollers include an 8-input
8-bit A/D converter and are appropriate for use in a wide range of applications. That range includes applications
with a small number of control circuits that were previously implemented in standard logic, and applications with
a larger scale such as home appliances, automotive equipment, communications equipment, office equipment,
and audio equipment such as decks and players.
Features
1) CMOS technology for a low-power consumption operation (A standby function that can be invoked under
program control is also provided.)
