GENERAL DESCRIPTION
The ML63512/63514 is a CMOS 4-bit microcontroller with built-in level detector and operates at
0.9 V (min.).
The ML63512/63514 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 ML63512 differ from those of
the ML63514.
48-pin TQFP and 64-pin TQFP packages are available for the ML63512 and ML63514.
FEATURES
Extensive instruction set
407 instructions
Transfer, rotate, increment/decrement, arithmetic operations, comparison, logic operations,
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.)
For RC oscillation, an external capacitor or internal
capacitor can be selected by mask option.
Program memory space
ML63512: 4K words
ML63514: 8K words
Basic instruction length is 16 bits/1 word
Data memory space
ML63512: 128 nibbles
ML63514: 256 nibbles
