LC87F7LC8A
„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 is selectable
2) Built-in 8-bit baudrate generator (maximum transfer clock cycle=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)
• 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)
„UART
1) Full duplex
2) 7/8/9 bit data bits selectable
3) 1 stop bit (2-bit in continuous data transmission)
4) Built-in baudrate generator
„AD Converter
• 8 bits × 15 channels
„PWM
• Multi frequency 12-bit PWM × 2 channels
„Remote Control Receiver Circuit
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
„Watchdog Timer
1) External RC watchdog timer
2) 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.
