GENERAL DESCRIPTION
The MTU410 is a single chip 4-bit microcontroller with LCD drivers. It can drive up to 3 common times or 25
segments, i.e. a 75-segment LCD driver. This 4-bit microcontroller contains a 4-bit parallel processing ALU,
1024 x 15-bit program ROM, 64 x 4-bit data RAM, input/output ports, alarm driver, timer, clock generator,
crystal and RC oscillator circuit, LCD driver and 79 powerful instructions in a single chip. The HALT instruction
can be used to stop all internal operations other than timer, clock generator, crystal/RC oscillator and LCD
driver. Very low current dissipation can be easily achieved by combining 4 kinds of interrupt functions and HALT
instruction to minimize the operation cycle.
