2 / 28 page LC87F2C64A No.A1935-2/28 Minimum Instruction Cycle Time • 250ns (12MHz at VDD=3.0 to 5.5V) • 750ns (4MHz at VDD=2.4 to 5.5V) Temperature Range • -30 to +70 degree Celsius Ports • Normal withstand voltage I/O ports Ports I/O direction can be designated in 1-bit units 71 (P0n, P1n, P2n, P30 to P34, P70 to P73, P8n, PAn, PBn, PCn, Pen, XT2, CF2) • Normal withstand voltage input port (Oscillator) 2 (XT1, CF1) • Reset pin 1 (RES) • Power pins 6 (VSS1 to VSS3, VDD1 to VDD3) 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 a 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 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) • Base timer 1) The clock is selectable from the sub-clock (32.768kHz crystal oscillation/slow RC oscillation), system clock, and prescaler output from timer 0. 2) Interrupts are programmable in 5 different time schemes. • Real time clock (RTC) 1) Used with a base timer, it can be used as a century + year + month + day + hour + minute + second counter. 2) Calendar counts up to December 31, 2799 with automatic leap-year calculation. High-speed Clock Counter • Count clocks with a maximum clock rate of 24MHz (when main clock is 12MHz) • Real-time output |
