IC693CPU350-EJ is a revision of the Series 90-30 Model 350 single-slot CPU module. The CPU uses a 25 MHz 80386EX processor, provides fixed 32 KB user program memory and installs in a CPU baseplate. It is intended for Series 90-30 control systems that require higher processing performance, extensive data tables and support for compatible communication option modules.
Processing capacity The 25 MHz 80386EX processor executes Boolean logic at a typical rate of 0.22 ms per 1K. Actual application scan depends on instruction mix, I/O servicing and communications.
Fixed memory structure CPU350 provides 32 KB of fixed user program memory. Its %R, %AI and %AQ capacities are fixed rather than user-configurable as on later higher-memory CPU models.
Communication path The built-in serial function uses the connector on the Series 90-30 power supply and supports SNP/SNP-X slave operation. Other protocols and networks require compatible option modules.
Revision-sensitive replacement The EJ suffix must be checked with the installed firmware, project software, baseplate, power supply and option modules. Preserve the application, hardware configuration and controller data before exchange.
SYSTEM RELATIONSHIP
CPU350 in the Series 90-30 Control Family
CPU340 / CPU341 Earlier 20 MHz choices with lower performance and different memory capacities.
CPU350-EJ 25 MHz processing, fixed 32 KB program memory and one power-supply serial path.
CPU351 / CPU352 Add two extra serial ports; CPU352 also provides hardware floating-point support.
CPU360 and later Higher memory or embedded-network alternatives, subject to project and hardware compatibility.
System relationship: CPU350 occupies a CPU baseplate slot and can manage a system with the CPU baseplate plus as many as seven compatible expansion or remote baseplates. Ethernet, PROFIBUS, FIP, Genius and other network functions depend on separately selected option modules.

PURCHASING FAQ
Five Questions Buyers Ask Before Ordering
What must be matched before replacing IC693CPU350-EJ?
Confirm the complete suffix, firmware, CPU baseplate, power supply capacity, project software, option modules and stored application. The suffix should be treated as part of the hardware identity.
Does IC693CPU350-EJ include an embedded Ethernet port?
No. CPU350 does not contain an embedded Ethernet interface. Ethernet communication requires a compatible Series 90-30 Ethernet option module.
Is the IC693CPU350-EJ 32 KB memory configurable?
No. CPU350 has 32 KB of fixed user program memory. It does not provide the larger configurable memory arrangement used by certain later CPU models.
How should the IC693CPU350-EJ program be protected during replacement?
Back up the application, configuration and required register data before removing the module. Check the battery-backed memory condition and confirm the flash or RAM restore method used by the site.
What should be tested after installing IC693CPU350-EJ?
Verify power and CPU status, RUN/STOP control, I/O update, expansion-base communication, serial communication, option modules, time-of-day operation and the complete machine sequence.
