7 / 88 page  7540 Group Rev.4.00 Jun 21, 2004 page 7 of 82 REJ03B0011-0400Z PIN DESCRIPTION Table 1 Pin description Function •Apply voltage of 2.2 to 5.5 V to Vcc, and 0 V to Vss. •Reference voltage input pin for A/D converter •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. •For using RC oscillator, short between the XIN and XOUT pins, and connect the capacitor and resistor. •If an external clock is used, connect the clock source to the XIN pin and leave the XOUT pin open. • When the on-chip oscillator is selected as the main clock, connect XIN pin to VSS and leave XOUT open. Function expect a port function Name Power source (Note 1) Analog reference voltage CNVss Reset input Clock input I/O port P0 I/O port P1 Pin Vcc, Vss VREF CNVss RESET XIN P00/CNTR1 P01/TYOUT P02/TZOUT P03/TXOUT P04–P07 Notes 1: VCC = 2.4 to 5.5 V for the extended operating temperature version and the extended operating temperature 125 °C version. 2: P26/AN6 and P27/AN7 do not exist for the 32-pin version, so that Port P2 is a 6-bit I/O port. 3: P35 and P36/INT1 do not exist for the 32-pin version, so that Port P3 is a 6-bit I/O port. • Key-input (key-on wake up interrupt input) pins • Timer Y, timer Z, timer X and timer A function pin •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 de- termined by program. •5-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 and P13 •8-bit I/O port having almost the same function as P0 •CMOS compatible input level •CMOS 3-state output structure •8-bit I/O port P10/RxD1 P11/TxD1 P12/SCLK1/SCLK2 P13/SRDY1/SDATA2 P14/CNTR0 P20/AN0–P27/AN7 P30–P35 P36/INT1 P37/INT0 I/O port P2 (Note 2) I/O port P3 (Note 3) • Serial I/O1 function pin • Serial I/O1 function pin • Serial I/O2 function pin • Timer X function pin • Input pins for A/D converter • Interrupt input pins •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 and P37). •CMOS 3-state output structure •P30 to P36 can output a large current for driving LED. XOUT Clock output •Whether a built-in pull-up resistor is to be used or not can be de- termined by program. |
