| Semiconductor ML63193 GENERAL DESCRIPTION This version: Feb. 10,1999 Preliminary 4-Bit Microcontroller with Built-in Dot Matrix LCD Driver and Melody Circuit The ML63193 is CMOS 4-bit microcontroller that guarantee operation at 0.9V. With an internal dot matrix LCD driver (64SEG.x 16COM.), this device is well suited for applications having liquid-crystal display (LCD) such as games, toys, watches, remote controllers etc. The ML63193 is masked-ROM device belonging to the M6318x series of the OLMS-63K family with an internal Oki's original CPU core nX-4/250. The ML63Q190 is the flash EEPROM version of ML63193, ML63187 and ML63189B The ML63Q190 is used to evaluate the software development. FEATURES * Extensive instruction set 408 instructions: Transfer, rotate, increment/decrement, arithmetic operations, compare, logic operations, mask operations, bit operations, ROM table reference, stack operations, flag operations, jump, conditional branch, call/return, control * Wide variety of addressing modes Indirect addressing mode for 4 types of data memory 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 : 61s ( @ 32.768kHz system clock ) : 1s ( @ 2MHz system clock ) * Clock generation circuit Low-speed clock: Crystal oscillation or RC oscillation selected with mask option ( 30kHz to 80kHz ) High-speed clock: Ceramic oscillation or RC oscillation selected with software ( 2MHz max. ) * Program memory space 64K words The basic instruction length is 16 bits per word.
