5 / 52 page MITSUBISHI MICROCOMPUTERS 3802 Group SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER 4 PIN DESCRIPTION Pin VCC, VSS CNVSS VREF AVSS RESET XIN XOUT P00–P07 P10–P17 P20–P27 P30/DA1, P31/DA2 P32–P37 P40/INT4, P41/INT0, P42/INT1, P43/INT2 P44/RXD, P45/TXD, P46/SCLK1, P47/SRDY1 P50/SIN2, P51/SOUT2, P52/SCLK2, P53/SRDY2 P54/CNTR0, P55/CNTR1 P56/PWM P57/INT3 P60/AN0– P67/AN7 Function • Apply voltage of 3.0 V–5.5 V to VCC, and 0 V to VSS. (Extended operating temperature version : 4.0 V to 5.5 V) • This pin controls the operation mode of the chip. • Normally connected to VSS. • If this pin is connected to VCC, the internal ROM is inhibited and external memory is accessed. • Reference voltage input pin for A-D and D-A converters • GND input pin for A-D and D-A converters • Connect to VSS. • Reset input pin for active “L” • Input and output signals for the clock generating circuit. • Connect a ceramic resonator or quartz-crystal oscillator between the XIN and XOUT pins to set the oscillation frequency. • If an external clock is used, connect the clock source to the XIN pin and leave the XOUT pin open. • The clock is used as the oscillating source of system clock. • 8 bit CMOS I/O port • I/O direction register allows each pin to be individually programmed as either input or output. • At reset this port is set to input mode. • In modes other than single-chip, these pins are used as address, data, and control bus I/O pins. • CMOS compatible input level • CMOS 3-state output structure • 8-bit CMOS I/O port with the same function as port P0 • CMOS compatible input level • CMOS 3-state output structure • 8-bit CMOS I/O port with the same function as port P0 • CMOS compatible input level • CMOS 3-state output structure • 8-bit CMOS I/O port with the same function as port P0 • CMOS compatible input level • CMOS 3-state output structure Function except a port function • D–A conversion output pins • External interrupt input pin • Serial I/O1 I/O pins • Serial I/O2 I/O pins • Timer X and Timer Y I/O pins • PWM output pin • External interrupt input pin • A-D conversion input pins Name Power source CNVSS Analog reference voltage Analog power source Reset input Clock input Clock output I/O port P0 I/O port P1 I/O port P2 I/O port P3 I/O port P4 I/O port P5 I/O port P6 |
