PC MIX value comparison
Memory capacity
CPU operation processing speeds
Note 3) Memory that stores the data used in sequence programs such as file registers and local devices
(with the exception of Basic Model CPU). As a built-in type RAM, the sequence program having a lot
of file registers and local devices stored in standard RAM can run rapidly.
Note 4) The SRAM card and ATA card memory capacity is the value after formatting.
* The PC MIX value is the average number of instructions such as the basic and data processing instructions
executed in 1 µs. A larger value indicates a higher processing speed.

PC MIX value (instruction/µs)
PC MIX value (instruction/µs)
Q series offers some of the highest processing performance on the market today; basic instruction processing time is 34ns and PC MIX
value is 10.3. By Mitsubishi's own “PC-MIX” performance metric, it is about 5 times faster than A2USHCPU-S1 and about 2.7 times faster
than the Q2ASHCPU. The CPU has dramatically increased floating-point operation speeds for PID and other arithmetic functions. The PC-
MIX aims to replicate real-word application performance by executing a mixed instruction set.
To construct small to large scaled systems, the Q
series has a wide variation of CPU modules having 8k
to 252k step program capacities and up to 256k bytes,
large-capacity standard RAMs, to meet the application
requirements from basic sequence control up to
complex multi-discipline applications.
A standard ROM (flash ROM) is built-in to enable
ROM operation without a memory card.
The efficient use of memory space allows the CPU to
contain twice the program of previous Mitsubishi
controllers (AnSHCPU).
Increased Operation Processing Speeds
Program Capacities and Large Standard RAM Capacities
The High-Performance Model QCPU and Process CPU accepts a range of optional memory cards that expand the processor's capacity up
to 32MB. Memory types available are SRAM card (1MB/2MB), flash card (2MB/4MB), or ATA card(8MB/16MB/32MB).
Depending on the memory used, storage for general purpose files such as Adobe™ Acrobat™, or CAD files is possible directly in the CPU,
which allows system documentation to reside directly in the controller. Storage for machine comments and file register data is also possible.
