MTU410 revision 2.7 04/28/1998 1/10 features 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.
