| MYSON TECHNOLOGY FEATURES * * * * * * * * * * * * * * * * * * * MTU410 4-Bit Micro-Controller with LCD Driver, 1K Word Very low current dissipation. Wide operating voltage range. Supports both Ag and Li batteries. Powerful instruction set. 4-level subroutine nesting (including interrupt). 4 event driven interrupts, 2 external and 2 internal. ROM size: 1024 x 15 bits. RAM size: 64 x 4 bits. Input ports: 2 ports/ 8 pins (S and M). Output port: 1 port/ 4 pins (P). Pseudo serial output port (P). Input/output ports: 2 ports/ 8 pins (I/OA and I/OB). Control outputs: ALARM, LIGHT. LCD driver outputs (can drive up to 75 LCD segments). Mask option to select 4 LCD drive modes: static, duplex (1/2 duty 1/2 bias, 1/3 duty 1/2 bias or 1/3 duty 1/3 bias). Mask option permits LCD driver output pins to be used for DC output ports; up to 25 pins are available. Segment PLA circuit permits any layout on LCD panel. Built-in clock generator (crystal or RC). Built-in voltage doubler, halver, tripler. 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. This datasheet contains new product information.
