No.A2046-2/30

Minimum Bus Cycle

• 83.3ns (12MHz at VDD=2.7V to 5.5V, Ta=-40°C to +85°C)

• 100ns (10MHz at VDD=2.2V to 5.5V, Ta=-40°C to +85°C)

• 250ns ( 4MHz at VDD=1.8V to 5.5V, Ta=-40°C to +85°C)

Note: The bus cycle time here refers to the ROM read speed.

Minimum Instruction Cycle Time

• 250ns (12MHz at VDD=2.7V to 5.5V, Ta=-40°C to +85°C)

• 300ns (10MHz at VDD=2.2V to 5.5V, Ta=-40°C to +85°C)

• 750ns ( 4MHz at VDD=1.8V to 5.5V, Ta=-40°C to +85°C)

Ports

Ports I/O direction can be designated in 1-bit units

12 (P1n, P20, P21, P70, CF2/XT2)

Ports I/O direction can be designated in 4-bit units

8 (P0n)

• Dedicated oscillator ports/input ports

1 (CF1/XT1)

• Reset pin

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 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)
