2 / 29 page LC87F7J32A No.A0886-2/29 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. |
