Modern spacecraft increasingly require flexible, reconfigurable payload interfaces that can adapt to multiple sensors, instruments, and mission profiles. The AN231E04 Field Programmable Analog Array (FPAA) from Okika Devices offers a powerful, and space-efficient solution to meet these needs.
The AN231E04 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.
+ Miniaturization: Replaces dozens of discrete analog components in one chip.
+ Low Latency: Real-time analog computation eliminates ADC/DSP round-trip delays.
+ In-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 AN231E04 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 AN231E04 FPAA provides a generational leap in spacecraft payload interface flexibility. It enables a modular, reconfigurable, and compact analog front-end critical for next-generation space systems.
