Lifecycle status is Active. No last-time-buy or end-of-life notice. Sourcing through standard independent distribution; quote against an RFQ.
Outside that band, derating or active cooling is required; for industrial or automotive thermal profiles look at the industrial-temperature siblings in the same family.
The memory is organized as 2M words by 18 bits, giving a total of 36 Mbit.
The 667 suffix indicates a higher 667 MHz clock rate. The 633 MHz version runs at a slightly lower peak bandwidth, which may relax PCB timing constraints. Both share the same 2M x 18 organization, supply range, and package.
The supply voltage range is 1.7V to 1.9V, centered on a nominal 1.8V rail.
It comes in a 165-ball FBGA (13x15 mm), surface mount.
