Ordering number : ENA0929 LC87F5NC8A CMOS IC FROM 128K byte, RAM 4096 byte on-chip LC87F5NC8A Timers Timer 0: 16-bit timer/counter with a capture register Mode 0: 8-bit timer with an 8-bit programmable prescaler (with an 8-bit capture register) 2 channels Mode 1: 8-bit timer with an 8-bit programmable prescaler (with an 8-bit capture register) + 8-bit counter (with an 8-bit capture register) Mode 2: 16-bit timer with an 8-bit programmable prescaler (with a 16-bit capture register) Mode 3: 16-bit counter (with a 16-bit capture register) Timer 1: 16-bit timer/counter that supports PWM/toggle output Mode 0: 8-bit timer with an 8-bit prescaler (with toggle outputs) + 8-bit timer/counter(with toggle outputs) Mode 1: 8-bit PWM with an 8-bit prescaler 2 channels Mode 2: 16-bit timer/counter with an 8-bit prescaler (with toggle outputs) (toggle outputs also from the lower-order 8-bits) Mode 3: 16-bit timer with an 8-bit prescaler (with toggle outputs) (The lower-order 8 bits can be used as PWM.) Timer 4: 8-bit timer with a 6-bit prescaler Timer 5: 8-bit timer with a 6-bit prescaler Timer 6: 8-bit timer with a 6-bit prescaler (with toggle outputs) Timer 7: 8-bit timer with a 6-bit prescaler (with toggle outputs) Base timer 1) The clock is selectable from the subclock (32.768kHz crystal oscillation), system clock, and timer 0 prescaler output. 2) Interrupts programmable in 5 different time schemes. High-speed Clock Counter 1) Can count clocks with a maximum clock rate of 24MHz (at a main clock of 12MHz). 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) SIO2: 8 bit synchronous serial interface 1) LSB first mode 2) Built-in 8-bit baudrate generator (maximum transfer clock cycle = 4/3 tCYC) 3) Automatic continuous data transmission (1 to 32 bytes) UART: 2 channels Full duplex 7/8/9 bit data bits selectable 1 stop bit (2 bit in continuous transmission mode) Built-in baudrate generator (with baudrates of 16/3 to 8192/3 tCYC) AD Converter: 8 bits 15 channels PWM: Multifrequency 12-bit PWM 4 channels Remote Control Receiver Circuit (sharing pins with P73, INT3, and T0IN) 1) Noise filtering function (noise filter time constant selectable from 1 tCYC, 32 tCYC, and 128 tCYC) 2) The noise filtering function is available for the INT3, T0IN, or T0HCP signal at P73. When P73 is read with an instruction, the signal level at that pin is read regardless of the availability of the noise filtering function. No.A0929-2/25
