chip scale atomic clock technical

"a Chip Scale Atomic Clock designed to deliver precise timing for space systems"

A chip scale atomic clock is a highly miniaturized atomic timekeeper that fits on a small semiconductor chip and keeps time by measuring atomic vibrations rather than relying on a mechanical or quartz oscillator. Like having a tiny, extremely accurate wristwatch inside a device, it provides precise, stable timing and frequency reference for networks, satellites, and instruments. Investors care because it enables better synchronization, reduces dependence on external GPS timing, and can improve reliability and performance in telecom, finance, defense, and autonomous systems.

cots technical

"Manufactured as a Commercial Off-The-Shelf (COTS) product"

COTS stands for “commercial off‑the‑shelf” and describes ready‑made products or software sold to many customers without custom modification. For investors, COTS adoption signals lower development cost, faster deployment and reduced technical risk compared with bespoke solutions — like buying a prebuilt appliance instead of commissioning a custom one — which can improve margins, speed time to market and affect procurement and revenue predictability.

gnss technical

"external timing references such as Global Navigation Satellite System (GNSS) signals"

GNSS stands for Global Navigation Satellite System, a network of satellites that provide precise location and timing information anywhere on Earth, like a constantly available digital map and clock. It matters to investors because many industries—transportation, agriculture, telecom, finance and defense—rely on this positioning and timing for products, services and critical infrastructure; improvements or disruptions in GNSS can change costs, create new revenue streams, or introduce operational risk.

The Space CSAC-SA65 combines atomic-clock accuracy with built-in 1 PPS disciplining and low-power consumption

CHANDLER, Ariz., Aug. 13, 2026 (GLOBE NEWSWIRE) -- The growing New Space market is fueling demand for smaller, less expensive space hardware to support short-duration missions for applications such as satellite-to-cellular communications, alternative navigation and Earth imaging. Microchip Technology (Nasdaq: MCHP) today 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 optimized for size-, weight- and power-constrained satellite designs. Its built-in 1 PPS input and output capabilities support synchronization 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 synchronization 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. For more information, visit Microchip's Clock and Timing Systems web page.

Development Tools

The CSAC-SA65 is supported by Microchip’s Clockstudio™ software for control and analysis of atomic clocks, as well as a CSAC Developer Kit.
