LC87F7J32A
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)
UART
• 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/8-bits × 12 channels
• 12 bits/8 bits AD converter resolution selectable
PWM: Multi frequency 12-bit PWM × 2 channels
Infrared Remote Control Receiver Circuit
1) Noise reduction function
(noise filter time constant: Approx. 120μs, when the 32.768kHz crystal oscillator is selected as the reference
voltage source.)
2) Supports data encoding systems such as PPM (Pulse Position Modulation) and Manchester encoding
3) X’tal HOLD mode release function
Watchdog Timer
• External RC watchdog timer
• Basetimer 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.
