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

  1. Ensure the RX3i rack power supply is completely disconnected prior to inserting or removing the IC695CPE302 CPU module from the baseplate slot.
  2. 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.
  3. Route RS-232 serial cables and Ethernet cables in grounded metal conduits separated from high-voltage AC lines to prevent signal interference.
  4. Connect and verify the RAM backup battery on the CPU or power supply module to prevent memory loss during unexpected power outages.
