4 / 45 page SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER 7536 Group MITSUBISHI MICROCOMPUTERS 4 PIN DESCRIPTION Table 1 Pin description Function •Apply voltage of 4.1 to 5.5 V to Vcc, and 0 V to Vss. •Reference voltage input pin for A-D converter •Output pin for pulling up a D- line with 1.5 k Ω external resistor •Chip operating mode control pin, which is always connected to Vss. •Reset input pin for active “L” •Input and output pins for main clock generating circuit •Connect a ceramic resonator or quartz crystal oscillator between the XIN and XOUT pins. •If an external clock is used, connect the clock source to the XIN pin and leave the XOUT pin open. Function expect a port function Name Power source Analog reference voltage USB reference voltage output CNVss Reset input •8-bit I/O port. •I/O direction register allows each pin to be individually pro- grammed as either input or output. •CMOS compatible input level •CMOS 3-state output structure •Whether a built-in pull-up resistor is to be used or not can be determined by program. •7-bit I/O port •I/O direction register allows each pin to be individually pro- grammed as either input or output. •CMOS compatible input level •CMOS 3-state output structure •CMOS/TTL level can be switched for P10, P12, P13. •When using the USB function, input level of ports P10 and P11 becomes USB input level, and output level of them becomes USB output level. •8-bit I/O port having almost the same function as P0 •CMOS compatible input level •CMOS 3-state output structure Pin Vcc, Vss VREF USBVREFOUT CNVss RESET P00–P07 P10/RxD/D- P11/TxD/D+ P12/SCLK P13/SDATA P14/CNTR0 P15, P16 P20/AN0– P27/AN7 P30–P35 P36/INT1 P37/INT0 P40, P41 Clock input Clock output I/O port P0 I/O port P1 I/O port P2 I/O port P3 I/O port P4 XIN XOUT •Whether a built-in pull-up resistor is to be used or not can be determined by program. •2-bit I/O port •I/O direction register allows each pin to be individually programmed as either input or output. •Key-input (key-on wake up interrupt input) pins •Serial I/O1 function pin •Serial I/O2 function pin •Timer X function pin •Input pins for A-D converter •Interrupt input pins •8-bit I/O port •I/O direction register allows each pin to be individually programmed as either input or output. •CMOS compatible input level (CMOS/TTL level can be switched for P36, P37). •CMOS 3-state output structure •P30 to P36 can output a large current for driving LED. |
