LC87F7J32A
Ports
• Normal withstand voltage I/O ports
Ports whose I/O direction can be designated in 1 bit units 15 (P1n, P30 to P31, P70 to P73, XT2)
Ports whose I/O direction can be designated in 4 bit units 8 (P0n)
(When N-channel open drain output is selected, data can be input in bit units.)
• Normal withstand voltage input port
1 (XT1)
• LCD ports
Segment output
24 (S00 to S23)
Common output
4 (COM0 to COM3)
Bias terminals for LCD driver
3 (V1 to V3)
Other functions
Input/output ports
24 (PAn, PBn, PCn,)
Input ports
7 (PLn)
• Dedicated oscillator ports
2 (CF1, CF2)
• Reset pin
1 (RES)
• Power pins
6 (VSS1 to VSS3, VDD1 to VDD3)
LCD Controller
1) Seven display modes are available (static, 1/2, 1/3, 1/4 duty × 1/2, 1/3 bias)
2) Segment output and common output can be switched to general-purpose input/output ports
Timers
• Timer 0: 16-bit timer/counter with two capture registers.
Mode 0: 8-bit timer with an 8-bit programmable prescaler (with two 8-bit capture registers) × 2 channels
Mode 1: 8-bit timer with an 8-bit programmable prescaler (with two 8-bit capture registers)
+ 8-bit counter (with two 8-bit capture registers)
Mode 2: 16-bit timer with an 8-bit programmable prescaler (with two 16-bit capture registers)
Mode 3: 16-bit counter (with two 16-bit capture registers)
• Timer 1: 16-bit timer that supports PWM/toggle outputs
Mode 0: 8-bit timer with an 8-bit prescaler (with toggle outputs)
+ 8-bit timer/counter with an 8-bit prescaler (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 possible 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 output)
• Timer 7: 8-bit timer with a 6-bit prescaler (with toggle output)
• Timer 8: 16-bit timer
Mode 0: 8-bit timer with an 8-bit prescaler × 2 channels (with toggle output)
Mode 1: 16-bit timer with an 8-bit prescaler (with toggle output)
• 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
• Day and time counter
1) Using with a base timer,it can be used as 65000 day + minute + second counter.
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.
