The R2X1N1P1A1T0F is the entry-processor configuration of the RXi2-XP platform, using an Intel Celeron G3902E — a 6th Gen Skylake dual-core processor at 1.6 GHz with a 25W TDP. Paired with 8 GB DDR4, a 128 GB SSD, Windows 10 IoT, and the XP's full-size chassis with 1 PCIe Gen3 x4 slot, it addresses a specific deployment scenario: extreme-temperature edge computing where the application workload is light but the environmental demands are severe.

Why put a Celeron in the largest RXi2 chassis?

The Celeron G3902E in the XP chassis is not about compute performance — it is about thermal margin. At 25W, the Celeron generates the same TDP as the i3-6100E but at roughly half the clock speed, meaning the passive cooling system operates well below its thermal limit even at +70°C ambient. The "F" suffix indicates Windows 10 IoT pre-installed, and the -40°C to +70°C extended temperature rating makes this configuration suitable for outdoor installations — pump station controllers, wellhead RTUs, or remote telemetry gateways — where a Celeron-class CPU is fully adequate for the data aggregation and protocol translation workload, but a standard-temperature IPC would fail on a winter cold start. The PCIe slot remains available for a cellular modem, satellite transceiver, or serial expansion card for legacy Modbus device connectivity. In this deployment model, the XP chassis is not chosen for expansion density — it is chosen for thermal ruggedness.
