ML63512A/63514A  
4-Bit Microcontroller with Built-in Level Detector, Melody Circuit, and Comparator,  
Operating at 0.9 V (Min.)  
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.  
FEATURES  
• Extensive instruction set  
407 instructions  
Transfer,rotate,increment/decrement,arithmeticoperations,comparison,logicoperations,  
mask operations, bit operations, ROM table reference, stack operations, flag operations,  
jump, conditional branch, call/return, control.  
• Wide variety 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 selectable by  
mask option (30 to 80 kHz)  
High-speed clock  
: Ceramic oscillation or RC oscillation selectable by  
mask option (2 MHz max.)  
• Program memory space  
ML63512A: 4K words  
ML63514A: 8K words  
Basic instruction length is 16 bits/1 word  
• Data memory space  
ML63512A: 128 nibbles  
ML63514A: 256 nibbles  
1/29
