This CPU module operates at 48 MHz using a 32-bit RISC architecture, executing complex logic and mathematical operations with high efficiency. It provides 128 KB of program memory and 64 KB of data memory, with an additional 256 KB of flash storage for non-volatile program retention. The module also includes 16 KB of battery-backed retentive memory, preserving critical data during power interruptions.
Extensive I/O Expansion Capabilities
This processor supports extensive I/O expansion, accommodating up to 1024 digital points and 256 analog channels through the MICREX-SX backplane. The FPU120S-A10 automatically detects connected modules during power-up, simplifying system configuration and reducing commissioning time. Users can freely mix digital, analog, and specialty modules to tailor the system to specific application requirements.
Communication and Integration Options
The FPU120S-A10 includes an RS-232C port for direct connection to programming software, enabling fast application downloads and online debugging. An additional RS-485 port supports Modbus RTU communication, facilitating integration with HMIs, drives, and remote I/O devices. The module also supports the Fuji SX Bus protocol, ensuring seamless interoperability with other MICREX-SX family components. Moreover, the CPU features a real-time clock for time-stamped events and scheduled tasks.
Physical and Power Specifications
Weighing 0.40 kg and measuring 100 mm x 60 mm x 95 mm, the FPU120S-A10 occupies a single slot in the SPH rack system. This module draws 350 mA from the 5 VDC backplane supply, consuming 4.0 W during normal operation. A replaceable CR2032 lithium battery preserves real-time clock data and retentive memory contents for approximately five years, ensuring reliable operation during power interruptions.
