ML63326
PRELIMINARY
ML63326
4-Bit Microcontroller with built-in Voice Synthesis and 1024-Dot LCD Drivers
GENERAL DESCRIPTION
The ML63326 is a low power 4-bit microcontroller which incorporates the OKI original CPU core nX-4/250 and
provides a minimum instruction execution time of 1µs (@2MHz).
It contains 24K-word program memory, 1536-nibble data memory, 4-bit input port, four 4-bit output ports,
five 4-bit and 2-bit input-output ports, shift register, LCD driver for up to 1024 segments, and voice synthesis,
including 1 megabit mask ROM for speech data, a 12-bit D/A converter and low-pass filter internally. Speech
ROM size can be expanded externally with further 4 megabits. The ML63326 is suitable for applications such
as games, toys, clocks etc. which use an LCD display and voice synthesis.
FEATURES
