LC87F7NC8A
ï® 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.
ï® Serial Interfaces
ï·ï SIO0: 8-bit synchronous serial interface
1) LSB first/MSB first made selectable
2) Built-in 8-bit baudrate generator (maximum transfer clock cycle ï½ 4/3tCYC)
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)
ï·ï 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)
ï® UART1
ï·ï Full duplex
ï·ï 7/8/9 bit data bits selectable
ï·ï 1 stop bit (2 bits in continuous data transmission)
ï·ï Built-in baudrate generator
ï® UART2
ï·ï Full duplex
ï·ï 7/8/9 bit data bits selectable
ï·ï 1 stop bit (2 bits in continuous data transmission)
ï·ï Built-in baudrate generator
ï® AD Converter :ï 12 bits ï´ 15 channels
ï® PWM :ï Multi frequency 12-bit PWM ï´ 2 channels
ï® Infrared Remote Control Receiver Circuit1
1) Noise reduction function (Time constant of noise reduction filter: approx. 120ïs, when selecting a 32.768kHz
crystal oscillator as a reference 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) Xâtal HOLD mode cancellation function
ï® Infrared Remote Control Receiver Circuit2
1) Noise reduction function
(Time constant of noise reduction filter: approx. 120μs, when selecting a 32.768kHz crystal oscillator as a
reference 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) Xâtal HOLD mode cancellation function
ï® Watchdog Timer
1) External RC watchdog timer
2) Interrupt and reset signals selectable
ï® Clock Output Function
1) Can output selected oscillation clock 1/1, 1/2, 1/4, 1/8, 1/16, 1/32, or 1/64 as a system clock.
2) Can output the source oscillation clock for the sub clock.
