General Description
ML63512A General Description
The ML63512A/63514A is a CMOS 4-bit microcontroller with built-in level detector and operates at 0.9 V (min.).
The ML63512A/63514A is an M6351x series mask ROM-version product of OLMS-63K family, which employs Oki's original CPU core nX-4/250.
The program memory capacity and data memory capacity of the ML63512A differ from those of the ML63514A.
48-pin TQFP and 64-pin TQFP packages are available for the ML63512A and ML63514A.

ML63512A Features
• Rich instruction set 408 instructions Transfer, rotate, increment/decrement, arithmetic operations, comparison, logic operations,mask operations, bit operations, ROM table reference, 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 : 61 ms (@ 32.768 kHz system clock) 1 ms (@ 2 MHz system clock)
• Clock generation circuit Low-speed clock : Crystal oscillation or RC oscillation selected with mask option (30 to 80 kHz) High-speed clock : Ceramic oscillation or RC oscillation selected with software (2 MHz max.)
• Program memory space
• ML63187 : 16K words
