AT68166FT-YM25-E-(ENG.-SAMPLES) [Microchip]

The AT68166FT is a 16Mbit SRAM in a hermetic Multi Chip Module (MCM) for space applications. It incorporates four 4Mbit AT60142FT SRAM dice and can be organized as one bank of 512Kx8, two banks of 512Kx16, or four banks of 512Kx8. It features rad-hard capabilities with a latch-up threshold of 80MeV.cm²/mg, Multiple Bit Upset immunity, and total dose tolerance of 300Krads, with fast access time. The MCM packaging reduces PCB area by 50% and weight by 75% compared to four 4Mbit packages. It operates at 3.3V and is 5V tolerant.
