2 / 24 page LC87F72C8A No.6712-2/24 (3) Minimum Bus Cycle Time: 100 ns (10 MHz) Note: The bus cycle time indicates ROM read time. (4) Minimum Instruction Cycle Time: 300 ns (10MHz) (5) Ports - Input/output ports Data direction programmable for each bit individually : 26 (P1n, P30-P35, P70-P73, P8n) Data direction programmable in nibble units : 8 (P0n) (When N-channel open drain output is selected, data can be input in bit units.) - Input ports : 2 (XT1,XT2) - LCD ports Segment output : 48 (S00-S47) Common output : 4 (COM0-COM3) Bias terminals for LCD driver 3 (V1-V3) Other functions Input/output ports : 48(PAn,PBn,PCn,PDn,PEn,PFn) Input ports : 7 (PLn) - Oscillator pins : 2 (CF1,CF2) - Reset pin : 1 (RES) - Power supply : 6 (VSS1-3,VDD1-3) (6) LCD controller - Seven display modes are available (static, 1/2, 1/3, 1/4 duty × 1/2, 1/3 bias) - Segment output and common output can be switched to general purpose input/output ports. (7) Small signal detection (MIC signals etc) - Counts pulses with the level which is greater than a preset value - 2 bit counter (8) Timers - Timer 0: 16 bit timer / counter with capture register Mode 0: 2 channel 8-bit timer with programmable 8 bit prescaler and 8 bit capture register Mode 1: 8 bit timer with 8 bit programmable prescaler and 8 bit capture register + 8 bit Counter with 8-bit capture register Mode 2: 16 bit timer with 8 bit programmable prescaler and 16 bit capture register Mode 3: 16 bit counter with 16 bit capture register - Timer 1: PWM / 16 bit timer with toggle output function Mode 0: 2 channel 8 bit timer (with toggle output) Mode 1: 2 channel 8 bit PWM Mode 2: 16 bit timer (with toggle output) Toggle output from lower 8 bits is also possible. Mode 3: 16 bit timer (with toggle output) Lower order 8 bits can be used as PWM. - Base Timer 1) The clock signal can be selected from any of the following : Sub-clock (32.768kHz crystal oscillator), system clock, and prescaler output from timer 0 2) Interrupts of five different time intervals are possible. |
