Backplane Bus Communication Velocity & Firmware Flash Compatibility
The IC695CPE302 utilizes a 1.1 GHz clock execution engine to drive high-speed backplane bus communication velocity across the PACSystems RX3i universal backplane. User application code, register data, and configuration parameters reside in 2 MB battery-backed SRAM, with long-term retention backed by non-volatile Flash memory. Firmware flash compatibility allows real-time operational updates and firmware maintenance from local storage media or network connection points without requiring module removal.
Frequently Asked Questions
Q: What power rail currents are required from the backplane for the IC695CPE302 module?
A: The module draws 1.0 A at +5 VDC, 1.0 A at +3.3 VDC, and 0.5 A at +24 VDC directly from the RX3i backplane power supply.
Q: How is non-volatile memory backup managed on the IC695CPE302 CPU?
A: Active program memory is stored in 2 MB of SRAM with battery backup, while system programs and permanent user configurations are stored in built-in Flash memory.
Q: What serial communications protocols are supported directly by the integrated RS-232 port?
A: The RS-232 serial port supports Modbus RTU Slave, SNP Slave, and general Serial I/O protocols.
Field Installation Guidelines
- Ensure the RX3i rack power supply is completely disconnected prior to inserting or removing the IC695CPE302 CPU module from the baseplate slot.
- Align the module with the card guides in slot 1 of the universal backplane, pressing firmly until the module latches engage with the chassis rail.
- Route RS-232 serial cables and Ethernet cables in grounded metal conduits separated from high-voltage AC lines to prevent signal interference.
- Connect and verify the RAM backup battery on the CPU or power supply module to prevent memory loss during unexpected power outages.
