Overview
The LC877 Series are 8-bit microcontrollers based on a CPU core that operates with a minimum instruction
cycle time of 100 ns and feature a rich set of peripheral functions. These peripheral functions include 24 to
128 KB of ROM, 2048, or 4096 bytes of RAM, an LCD display controller/driver, a multifunction 16-bit timer
/counter circuit that can be split into 8-bit timers, a 16-bit timer/PWM generator that can be split into 8-bit
timers, four 8-bit timers with built-in prescaler, a clock time base timer, a high-speed clock counter, a system
clock divider function, a synchronous SIO circuit with an automatic transfer function, a synchronous
/asynchronous SIO circuit, an 8-bit A/D converter, a small-signal detection circuit, and a powerful interrupt
system.
■ LCD display controller/driver
(48 segments 4 common signals)
■ Small-signal detection circuit
(for microphone and similar signals)
■ Timers
●
One 16-bit timer/counter with capture register
(can be divided and used as two 8-bit timers)
●
One 16-bit timer/counter with PWM/toggle output function
(can be divided and used as two 8-bit timers)
●
Four 8-bit timers with 6-bit prescaler function
(LC877B series)
●
Clock time base timer
■ High-speed clock counter
This circuit can count up to 20 MHz clock signals when
a 10 MHz main clock frequency is used.
■ Serial interface circuits
●
8-bit synchronous serial interface
●
8-bit synchronous/asynchronous serial interface
■ AD converter
15-input 8-bit A/D converter (LC877B series)
■ Remote controller receiver
(shared function of the P73/INT3/TOIN pin)
■ Watchdog timer
(using external resistor and capacitor components)
■ Interrupts
20 sources/10 vectors (LC877B series)
(Multiple interrupt control with three levels: low level (L),
high level (H), and highest level (X))
■ High-speed multiply and divide instructions
●
16 bits 8 bits (execution time: 5 tCYC)
●
24 bits 16 bits (execution time: 12 tCYC)
●
16 bits ÷ 8 bits (execution time: 8 tCYC)
●
24 bits ÷ 16 bits (execution time: 12 tCYC)
■ System clock divider function
■ Standby functions
●
Halt mode: instruction execution is stopped,
peripheral circuit operation continues
●
Hold mode: instruction execution is stopped,
peripheral circuit operation is stopped
●
Crystal hold mode: instruction execution is stopped,
peripheral circuit operation other than the clock time
base timer is stopped
