SM3513
DESCRIPTION
The SM3513 is a CMOS 4-bit single-chip micro-
computer for databank incorporating data memory
RAM, LCD driver (the output is adjustable in 16
steps for various contrast), key/switch input circuit,
8-bit parallel I/O port, 3 output ports, external mem-
ory control circuit, buzzer circuit and voltage detec-
tor circuit. One of three ports contains special out-
put circuit for infrared (IR) communication. It is easy
to realize timer function by timer signal interrupt
since the oscillator circuit is built-in.
