CMOS IC
LC573904
4-Bit Microcontroller
with 4K-Byte ROM, 120 × 4Bits RAM and LCD Driver
Preliminary
Overview
The LC573904 is a CMOS 4-bit microcontroller that operates on low voltage and very low power consumption. It also
contains 4K-byte ROM, 128 × 4 bits RAM, LCD drivers and melody function.

(4) Input / Output Terminals
- Input ports
: 4 terminals (S-port : 4 terminals)
- Input / Output ports : 8 terminals (P0 port : 4 terminals, P1 port : 4 terminals)
[Notes] When using the P1 port for output, the “L” level hold Tr. of P1 should be OFF.
If P1 port becomes “H” level with “L” level hold Tr. on, it causes the through current from VDD to GND
and increases the current consumption.
- Output ports
: 2 terminals (Buzzer / melody output terminal : 1 terminal,
General output port : 1 terminal)
- LCD segment output ports
: 32 terminals (Possible to use output port by mask option)
- LCD common output ports
: 4 terminals
