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 1ms (@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

· Rich instruction set

439 instructions

Transfer, rotate, increment, decrement, arithmetic operations, comparison, logic operations, mask

operations, bit operations, ROM table reference, external memory transfer, stack operations, flag

operations, branch, conditional branch, call/return, control.

· Rich selection of addressing modes

Indirect addressing of four data memory types, with current bank register, extra bank register, HL register

and XY register.

Data memory bank internal direct addressing mode.

· Processing speed

Two clocks per machine cycle, with most instructions executed in one machine cycle.

Minimum instruction execution time

: 61ms ( @32.768kHz system clock )

1ms ( @2MHz system clock: 1/2 of high-speed clock )

· Clock generation circuit

Low-speed clock:

: 32.768kHz crystal oscillator,

or 32kHz ±40% (@1MW ±10%), RC oscillator (by mask option)

: 4MHz (max.) crystal oscillator,

High-speed clock:

or 2MHz ±40% (@20kW ±5%) RC oscillator (by software selection)

· Program memory space

24K words

Basic instruction length is 16 bits / 1 word

· Data memory space

1536 nibbles

· External data memory space

64kbyte ( expandable )

· Stack level

Call stack level

: 16 levels
