LC87F2C64A
„SIO
• SIO0: 8-bit synchronous serial interface
1) LSB first/MSB first mode selectable
2) Built-in 8-bit baud rate generator (maximum transfer clock cycle = 4/3 tCYC)
3) Automatic continuous data transmission (1 to 256 bits specifiable in 1 bit units, suspension and resumption of
data transmission possible in 1 byte units)
4) HOLD/X’tal HOLD mode release function by receiving 1-byte (8-bit clock)
• 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 clocks)
Mode 1: Asynchronous serial I/O (half-duplex, 8 data bits, 1 stop bit, 8 to 2048 tCYC baud rates)
Mode 2: Bus mode 1 (start bit, 8 data bits, 2 to 512 TCYC transfer clocks)
Mode 3: Bus mode 2 (start detect, 8 data bits, stop detect)
„UART: 2 channels
• Full duplex
• 7/8/9 bit data bits selectable
• 1 stop bit (2-bit in continuous data transmission)
• Built-in baudrate generator
„Remote Control Receiver Circuit
• Noise rejection function on P73/INT3/T0IN pin (noise rejection filter’s time constant can be selected from 1,
32 or 128 tCYC.)
„AD Converter: 12 bits × 16 channels
• 12 bits/8 bits AD converter resolution selectable
„PWM: 4 channels
• Multi frequency 12-bit PWM
„Clock Output Function
• Output clock with a frequency 1/1, 1/2, 1/4, 1/8, 1/16, 1/32 or 1/64 of the source clock of the system clock.
• Output clock of the sub-clock.
„Buzzer Output
• 2kHz or 4kHz buzzer output can be generated using base timer.
„Watchdog Timer
• Watchdog timer can generate interrupt or system reset.
• Two types of watchdog timers are available:
(1) External RC watchdog timer
(2) Base timer watchdog timer
• Watchdog timer with base timer can select only one period (1, 2, 4 or 8s) by the user option.
Once set the watchdog timer period and start the watchdog timer, the period is not changeable.
