AT60142H Image

The AT60142H from Microchip Technology is a Rad-Hard CMOS Static RAM (SRAM) with a storage capacity of 512 MB. This SRAM has a read-and-write access time of 15 nsec. It requires an operating voltage of 3.3 V and has a low power consumption of 3.3-650 mW. The SRAM supports TTL-compatible inputs and outputs and is designed based on 0.25 µm radiation hardened process. It is tested up to a Total Dose of 300 krads (Si) and follows MIL-STD-883 standards. This RAM has no single event latch-up below the LET Threshold of 80 MeV/mg/cm2 (at 125 degrees C) and is ideal for applications that require fast computing with low power consumption such as aerospace electronics, portable instruments, or embarked systems.
