2 / 36 page LC87F17C8A www.onsemi.com 2 ■ Ports I/O ports 31 (P00 to P07, P10 to P17, P20 to P24, P30 to P32, P70 to P73, PWM0, PWM1, XT2) USB ports 4 (UAD+, UAD–, UBD+, UBD–) Dedicated oscillator ports 2 (CF1, CF2) Input-only port (also used for the oscillator) 1 (XT1) PLL filter pins 2 (UFILT, AFILT) Reset pin 1 (RES) Debugger-dedicated pin 1 (OWP0) Power supply pins 6 (VSS1 to 3, VDD1 to 3) ■ Timers Timer 0 : 16-bit timer/counter with 2 capture registers Mode 0 : 8-bit timer with an 8-bit programmable prescaler (with two 8-bit capture registers) 2 channels Mode 1 : 8-bit timer with an 8-bit programmable prescaler (with two 8-bit capture registers) + 8-bit counter (with two 8-bit capture registers) Mode 2 : 16-bit timer with an 8-bit programmable prescaler (with two 16-bit capture registers) Mode 3 : 16-bit counter (with two 16-bit capture registers) Timer 1 : 16-bit timer/counter that supports PWM/toggle output Mode 0 : 8-bit timer with an 8-bit prescaler (with toggle output) + 8-bit timer/counter with an 8-bit prescaler (with toggle output) Mode 1 : 8-bit PWM with an 8-bit prescaler 2 channels Mode 2 : 16-bit timer/counter with an 8-bit prescaler (with toggle output) (Toggle output also possible from low-order 8 bits.) Mode 3 : 16-bit timer with an 8-bit prescaler (with toggle output) (Low-order 8 bits can be used as a PWM output.) Timer 4 : 8-bit timer with a 6-bit prescaler Timer 5 : 8-bit timer with a 6-bit prescaler Timer 6 : 8-bit timer with a 6-bit prescaler (with toggle output) Timer 7 : 8-bit timer with a 6-bit prescaler (with toggle output) Base timer <1> The clock can be selected from among a subclock (32.768 kHz crystal oscillator), low-speed RC oscillator clock, system clock, and timer 0 prescaler output. <2> Interrupts programmable in 5 different time schemes. ■ Serial Interfaces SIO0 : Synchronous serial interface <1> LSB first/MSB first selectable <2> Transfer clock cycle : 4/3 to 512/3 tCYC <3> Continuous automatic data transmission (1 to 256 bits can be specified in 1-bit units) (Suspension and resumption of data transfer possible in 1-byte units) SIO1 : 8-bit asynchronous/synchronous serial interface Mode 0 : Synchronous 8-bit serial I/O (2- or 3-wire configuration, 2 to 512 tCYC transfer clock) Mode 1 : Asynchronous serial I/O (half-duplex, 8 data bits, 1 stop bit, 8 to 2048 tCYC baudrate) Mode 2 : Bus mode 1 (start bit, 8 data bits, 2 to 512 tCYC transfer clock) Mode 3 : Bus mode 2 (start detection, 8 data bits, stop detection) SIO4 : Synchronous serial interface <1> LSB first/MSB first selectable <2> Transfer clock cycle : 4/3 to 1020/3 tCYC <3> Continuous automatic data transmission (1 to 8192 bytes can be specified in 1-byte units) (Suspension and resumption of data transmission possible in 1-byte units or in word units) <4> Clock polarity can be selected. <5> CRC16 calculator circuit built- in SMIIC0 : Single-master I2C/8-bit synchronous SIO Mode 0 : Communication in single-master mode. Mode 1 : 8-bit synchronous serial I/O (data MSB first) |
