Modern spacecraft increasingly requires flexible, reconfigurable payload interfaces that can adapt to multiple sensors, instruments, and mission profile—the AN231E03 Field Programmable Analog Array (FPAA) from Okika Devices offers a powerful, low-power, and space-efficient solution to meet these needs.

The AN231E03 replaces bulky analog front-end circuits with a programmable analog signal path, enabling real-time processing and configuration of analog signals from diverse payloads. It dramatically simplifies hardware design, enhances adaptability, and reduces size, weight, and power (SWaP).

Key Benefits

• Programmable Analog Signal Path: Real-time reconfigurable filters, amplifiers, and signal routing
• Multi-Payload Support: Reuse one interface board across payloads with differing analog requirements
• Low Power Consumption: Ideal for SWaP-constrained smallsats and hosted payloads
• Miniaturization: Replaces dozens of discrete analog components in one chip
• Low Latency: Real-time analog computation eliminates ADC/DSP round-trip delays
• On-Orbit Reconfiguration: Supports in-flight updates via microcontroller or FPGA
• High Precision: Tunable capacitors and low-noise blocks for sensitive instrumentation

Example

Sensors and instruments connect to the AN231E03 FPAA for analog signal conditioning. A microcontroller configures the FPAA and communicates with the spacecraft data bus. This enables plug-and-play analog interfacing and dynamic re-tasking of the same hardware for new missions or experiments.

Applications

• Adaptive science payload platforms
• Multi-mission CubeSats
• RF and signal-processing front ends
• Hosted payload buses with standardized interfaces

Okika’s AN231E03 FPAA provides a generational leap in spacecraft payload interface flexibility and enables a modular, reconfigurable, and compact analog front-end critical for next-generation space systems.
