It contains 3K-byte ROM, 52-nibble RAM, 4-bit ALU, 13-level subroutine nesting, 22-stage time base, one 12-bit timer for the kernal function and one high speed counter. EM73P362 also contains 5 interrupt sources, 1 input port, 4 bidirection ports, built-in watch-dog-timer and LCD driver (27x3 to 15x3). Except low-power consumption and high speed, EM73P362 has the STOP mode and IDLE mode operation for power saving function. FEATURES FEATURES FEATURES FEATURES FEATURES • Operation voltage : 1.3V to 1.8V. (clock frequency : 32K Hz) • Clock source : Single clock system for crystal, connect a external resistor or external clock source, available by mask option. • Instruction set : 109 powerful instructions. • Instruction cycle time : Up to 122µs for 32 K Hz. • ROM capacity : 3072 x 8 bits. • RAM capacity : 52 x 4 bits. • Input port : 1 port (4-bit). • Bidirection port : 4 ports (P4, P6, P7, P8) are available by mask option. P4 is a high current port. (P4.0 and TONE available by mask option. P4.1~P4.3 are shared with the input/ output of RFO.) P6, P7 and P8 are shared with SEG15-SEG26. • 12-bit timer : One 12-bit timer is programmable for timer. • High speed counter : The high speed counter includes one 8-bit high speed counter, one 12-bit general counter and a resistor frequency oscillator. It has resistor to frequency oscillation mode, melody mode and auto load timer mode. • Built-in time base counter: 22 stages. • Subrountine nesting : Up to 13 levels. • Interrupt : External interrupt . . . . . . 2 input interrupt sources. Internal interrupt . . . . . . 2 timer overflow interrupts, 1 time base interrupt. • LCD driver : 27x3 to 15x3 dots available by mask option. 1/3, 1/2 and static three kinds of duty (1/2 bias) selectable. The programming method of LCD driver is RAM mapping. • Built-in watch-dog-timer is available by mask option. • Built-in low battery detector. • Power saving function : STOP mode and IDLE mode. • Package type : Chip form 50 pins. QFP 52 pins (CQ). QFP 100 pins (BQ). |
