2 / 21 page LC87F2708A No.A1335-2/21 Minimum Bus Cycle Time Note1 • 100ns (10MHz) VDD=2.7 to 5.5V Note2 Minimum Instruction Cycle Time • 300ns (10MHz) VDD=2.7 to 5.5V Note2 Note1: The bus cycle time here refers to the ROM read speed. Note2: Use this product in a voltage range of 3.0 to 5.5V because the minimum release voltage (PORRL) of the power-on reset (POR) circuit is 2.87V ±0.12V. Ports • I/O ports Ports whose I/O direction can be designated in 1-bit units 11 (P10 to P16, P30 to P33) • Reset pins 1 (RES) • Power pins 2 (VSS1, VDD1) 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 an 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 can provide with 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 output also possible from the lower-order 8 bits) Mode 3: 16-bit timer with an 8-bit prescaler (with toggle outputs) (Lower-order 8 bits may be used as PWM) Serial Interface • SIO7: 8-bit synchronous serial interface 1) LSB first/MSB first mode selectable 2) Built-in 8-bit baudrate generator (maximum transfer clock cycle=4/3 tCYC) High-Speed 12-bit PWM • System clock/high-speed RC oscillation clock (20MHz or 40MHz) operation selectable • Duty/period programmable • Continuous PWM output/specific count PWM output (automatic stop) selectable High-speed Pulse/Period Counter • HCT1: High-speed pulse width/period counter 1 1) System clock/high-speed RC oscillation clock (20MHz or 40MHz) operation selectable 2) H-level width/L-level width/period measurement modes selectable 3) Input triggering noise filter • HCT2: High-speed pulse width/period counter 2 1) System clock/high-speed RC oscillation clock (20MHz or 40MHz) operation selectable 2) Can measure both L-level width and period simultaneously. 3) Input triggering noise filter 4) Input trigger selectable (from 3 signals, i.e., P11/HCT2IN, P31/HCT2IN, and analog comparator output) AD Converter: 12 bits × 7 channels • 12-/8-bits AD converter resolution selectable Analog Comparator • Sends output to the P32/CMPO port (polarity selectable). • Edge detection function (shared with INTC and also allows the selection of the noise filter function) |
