4-Bit Microcontroller With Built-in RC Oscillation Type A/D Converter And LCD Driver ML64P1684-Bit Microcontroller With Built-in RC Oscillation Type A/D Converter And LCD Driver

The ML64P168 is a one-time-programmable ROM-version product, which has one-time PROM (OTP) as internal program memory. On the other hand, the ML64168 is a mask ROM-version product, which has mask ROM as internal program memory. Unlike the mask ROM-version product ML64168 , the ML64P168 cannot be supplied in the form of a chip. The ML64P168 has two operation modes, Microcontroller operation mode and PROM mode. The Microcontroller operation mode is used to operate the ML64P168 like a ML64168 and the PROM mode is used to program or read the PROM. The ML64P168 is a low power 4-bit Microcontroller incorporating the Okis original CPU core nX-4/30. The ML64P168 provides a minimum instruction execution time of 4.3s (@700kHz). The ML64P168 contains 8160-byte program memory, 512-nibble data memory, three 4-bit input-output ports, 4-bit input port, 4-bit output port, 2-channel RC oscillation type A/D converter LCD Driver for up to 120 segments, and buzzer output port.
