MB91460H Series

Mask ROM and EVA device:

CMOS Hysteresis input pin

Flash device:

CMOS input pin

12 V withstand (for MD [2:0])

CMOS Hysteresis input pin

Pull-up resistor value: 50 kΩ approx.

High-speed oscillation circuit:

• Programmable between oscillation mode

(external crystal or resonator connected

to X0/X1 pins) and

Fast external Clock Input (FCI) mode

(external clock connected to X0 pin)

• Feedback resistor = approx. 2 * 0.5 MΩ.

Feedback resistor is grounded in the center when the

oscillator is disabled or in FCI mode.

Low-speed oscillation circuit:

• Feedback resistor = approx. 2 * 5 MΩ.

Feedback resistor is grounded in the center when the

oscillator is disabled.
