88CU74-2

◆ Time base timer

◆ Divider output function

◆ Watchdog timer

• Interrupt source/reset output (programmable)

◆ 8-bit serial interface: 1 channel

• With 8 bytes transmit/receive data buffer

• Internal/External serial clock, and 4/8-bit mode

◆ Serial bus interface

• 8-bit SIO/I2C bus mode

◆ 8-bit successive approximate type AD converter with sample and hold

• Analog inputs: 12 channels conversion time:

μs at 8 MHz (High-speed conversion mode),

μs at 12.5 MHz (Low-speed conversion mode)

◆ Vacuum fluorescent tube driver (Automatic display)

• High breakdown voltage ports (Max 40 V × 37 bits)

• Programmable grid scan output

◆ Dual clock operation

• Single/Dual-clock mode (selection)

◆ Five power saving operating modes

• STOP mode:

Oscillation stops. Battery/Capacitor back-up. Release by stop pin input.

• SLOW mode: Low power consumption operation using low-frequency clock.

• IDLE1 mode: CPU stops, and Peripherals operate using high-frequency clock. Release by

interrupts.

• IDLE2 mode: CPU stops, and Peripherals operate using high-and low-frequency clock. Release

by interrupts.

• SLEEP mode: CPU stops, and Peripherals operate using low-frequency clock. Release by

interrupts.

◆ Wide operating voltage: 2.7 to 5.5 V at 32.8 kHz, 4.5 to 5.5 V at 12.5 MHz/32.8 kHz

◆ Emulation Pod: BM88CU74F0A
