GENERAL DESCRIPTION

EM73361A is an advanced single chip CMOS 4-bit micro-controller. It contains 3K-byte ROM, 52-nibble RAM,

4-bit ALU, 13-level subroutine nesting, 22-stage time base, two 12-bit timer/counters for the kernel function.

EM73361A also contains 3 interrupt sources, 1 input port, 4 bidirection I/O ports, built-in watch-dog-timer

counter, tone generator and LCD driver (27x3 to 13x3).

Except low-power consumption and high speed, EM73361A also have a sleep mode operation for power saving.

FEATURES

FEATURES

• Operation voltage

: 2.2V to 3.6V(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

: 122µs for 32K Hz.

• ROM capacity

: 3072 X 8 bits.

• RAM capacity

: 52 X 4 bits.

• Input port

: 1 port (P0)(Pull-up and pull-down resistor with wakeup function available by

mask option).

• Bidirection port

: 4 ports (P4, P5, P6, P7) are available by mask option. (each I/O pin is push-pull

and open-drain available by mask option) P4.0 is high current pin (P4.0 and

TONE available by mask option). P4.2~P4.3, P5, P6 and P7 are shared with

SEG26-SEG13 by mask option.

• 12-bit timer/counter

: Two 12-bit timer/counters are programmable for timer mode.

• Low voltage reset (LVR) : Reset at 1.5V, and reset release at 1.8V.

• Tone generator

: There is a built-in tone generator.
