ML63293  
Preliminary  
4-Bit Microcontroller with Built-in LCD Driver ( 68SEG. ´ 32COM. ) and Melody Circuit  
GENERAL DESCRIPTION  
The ML63293 is a CMOS 4-bit microcontroller with built-in LCD driver and Melody circuit.  
The ML63293 is an M63xxx series mask ROM-version product of OLMS-63K family, which employs  
Oki’s original CPU core nX-4/250.  
The ML63293 contains 64K-word program memory, 3K-nibble data memory, 4-bit input port, 16-bit  
output ports, 24-bit input/output port, LCD driver for up to 2176 segments, and melody circuit.  
The ML63Q290 is the flash EEPROM version of ML63293.  
The ML63Q290 is used to evaluate the software development.  
APPLICATION  
The ML63293 is suitable for applications such as games, toys, watches, etc. which are provided with  
an LCD display and Melody output.  
FEATURES  
·Extensive instruction set  
408 instructions  
Transfer, rotate, increment,/decrement, arithmetic operations, comparison, logic operations,  
mask operations, bit operations, ROM table reference, external memory transfer, stack  
operations, flag operations, jump, conditional branch, call / return, control.  
·Wide variety 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  
2 clocks per machine cycle, with most instructions executed in 1 machine cycle.  
Minimum instruction execution time : 61ms ( @32.768kHz system clock )  
1ms ( @2MHz system clock )  
·Clock generation circuit  
Low-speed clock  
: Crystal oscillation or RC oscillation selected with mask  
option ( 30k to 80kHz )  
High-speed clock  
: Ceramic oscillation or RC oscillation selected with  
software ( 2MHz max. )
