LC87F7DC8A
„High-speed Clock Counter
1) Can count clocks with a maximum clock rate of 20MHz (at a main clock of 10MHz).
2) Can generate output real-time.
„SIO
• SIO0: 8-bit synchronous serial interface
1) LSB first/MSB first mode selectable
2) Built-in 8-bit baudrate 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)
• 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 baudrates)
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)
„UART1
• Full duplex
• 7/8/9 bit data bits selectable
• 1 stop bit (2-bit in continuous data transmission)
• Built-in baudrate generator
„UART2
• Full duplex
• 7/8/9 bit data bits selectable
• 1 stop bit (2-bit in continuous data transmission)
• Built-in baudrate generator
„AD Converter: 12 bits × 15 channels
„PWM: Multi frequency 12-bit PWM × 2 channels
„Remote Control Receiver Circuit1
1) Noise rejection function
(Units of noise rejection filter: about 120μs, when selecting a 32.768kHz crystal oscillator as a clock.)
2) Supporting reception formats with a guide-pulse of half-clock/clock/none.
3) Determines a end of reception by detecting a no-signal periods (No carrier).
(Supports same reception format with a different bit length.)
4) X’tal HOLD mode release function
„Remote Control Receiver Circuit2

2) Supporting reception formats with a guide-pulse of half-clock/clock/none.
3) Determines a end of reception by detecting a no-signal periods (No carrier).
(Supports same reception format with a different bit length.)
4) X’tal HOLD mode release function
„Watchdog Timer
• External RC watchdog timer
• Interrupt and reset signals selectable
„Clock Output Function
1) Able to output selected oscillation clock 1/1, 1/2, 1/4, 1/8, 1/16, 1/32, 1/64 as system clock.
2) Able to output oscillation clock of sub clock.
