Microchip advances space-grade timing with enhanced radiation tolerance and extended temperature performance
The growing New Space market is fuelling demand for smaller, less expensive space hardware to support short-duration missions for applications such as satellite-to-cellular communications, alterna- tive navigation and Earth imaging. Microchip Technology today (13 August) announces it expanded its atomic clock portfolio with the radiation-tolerant Space CSAC-SA65, a Chip Scale Atomic Clock designed to deliver precise timing for space systems.
The device provides a compact, low-power alternative to traditional radiation-hardened timing solutions, helping developers reduce size, weight, power and cost while maintaining accuracy.
Building on the heritage of Microchip’s Space CSAC-SA45, the Space CSAC-SA65 extends radiation tolerance to at least 30 kRad and operates in extended temperature ranges from –40°C to +80°C. Consuming less than 120 mW and occupying less than 17 cc of volume, the device is optimised for size-, weight- and power- constrained satellite designs. Its built-in 1 PPS input and output capabilities support synchronisation for satellite systems, while its atomic stability enables extended operation without continuous reliance on external timing references such as Global Navigation Satellite System (GNSS) signals.
“By enabling one of the lowest power atomic clocks to thrive in extreme conditions, even the smallest CubeSat can now fly with atomic accuracy,” said Randy Brudzinski, corporate vice president of Microchip’s frequency and time systems business unit. “The Space CSAC-SA65 brings atomic-clock performance to applications where size, weight, power and cost are tightly constrained, helping developers maintain synchronisation and timing accuracy even when external timing references are unavailable.”
Manufactured as a Commercial Off-The-Shelf (COTS) product using radiation-tolerant commercial electronic components, the device can offer shorter lead times and lower overall costs compared to traditional space-grade oscillators. Designed for Low Earth Orbit (LEO) missions, the CSAC-SA65 is well suited for applications including satellite timing and frequency control, satellite clock reference, assured positioning, navigation and timing (PNT), and satellite cross-linking.
Microchip offers an extensive portfolio of clock and timing systems, ranging from miniature component oscillators, to small plug-in timing server cards, to multi-rack time scale systems. As a primary contributor to the world’s time, Microchip’s timing solutions are trusted, reliable and resilient.
ROLEC’s technoPLUS: IP-rated Pole-mount Plastic Enclosures for IoT/IIoT and Factory Automation
IoT/IIoT and factory automation are driving demand for ROLEC’s updated pole-mountable technoPLUS (IP 66, IP 67, IP 69K) plastic enclosures. Electronics designers specify them for ‘close-to-the-process’ devices that must survive dust, moisture and regular washdowns.
Compact technoPLUS provides robust protection – allowing industrial electronics to be mounted directly on machine frames, production-line supports, conveyor structures or masts at the heart of the process.
These tough, UV-stable enclosures are ideal for IIoT LoRaWAN, NB-IoT and MQTT edge gateways, cellular telemetry units, industrial data loggers, edge computing nodes, remote PLC communications and wireless sensor concentrators.
Factory automation applications include industrial re- mote I/O stations, machine condition monitoring, wireless industrial networking, automated guided vehicle (AGV) and autonomous mobile robot (AMR) infrastructure, machine vision, distributed PLC systems, factory environmental monitoring and safety technology.
Versatile technoPLUS can be mounted either vertically or horizontally: the unique pole/mast attachment (accessory) is designed for use with plastic or metal straps. ‘Lid closed’ installation protects the electronics and seal when the equipment is being fitted or removed in bad weather or challenging industrial environments. Hinged polypropylene covers hide the lid screws and mounting channels.
The lid is recessed to accommodate a membrane keypad, face plate or product label. Integrated supports hold the lid in place when it is open. Inside the enclosure, there are screw bosses for PCBs, mounting plates (accessory) and terminal rails (accessory).
The enclosures are moulded from ASA (UL 94 HB) in light grey (RAL 7035) with anthracite grey (RAL 7016) cover trims. There are five sizes from 90 x 130 x 70 mm to 170 x 270 x 90 mm.
ROLEC can supply technoPLUS fully customised. Services include CNC machining, painting, engraving, EMC shielding, printing, displays, and assembly of accessories.
