1 Mbit parallel Flash in a ceramic CQCC32 — the 150 ns access time sets the bus margin
The Micron MT28F010-15 is a 1 Mbit (128Kx8) parallel NOR Flash memory with a 150 ns access time, operating from a single 5 V supply. Packaged in a ceramic CQCC32, it is built for environments where a hermetic seal and extended temperature handling matter — avionics, missile guidance, satellite, or downhole instrumentation. The 150 ns access time sets the read-cycle window for the host bus; a slower microcontroller or ASIC interface will meet it comfortably, but a faster pipeline may need wait-state insertion or a lower-access-time part.
Lifecycle and sourcing — active but flagged eol_hot
The MT28F010-15 carries an Active product status, but the lifecycle stage is flagged eol_hot — meaning end-of-life planning is already underway or imminent. For a BOM line that depends on this exact ceramic-packaged Flash, the window for last-time-buy commitments is narrowing. We source and quote this part to order against an RFQ through independent distribution; availability and current pricing are confirmed at quote time. No official successor is listed, so any replacement will require a board redesign or a functionally equivalent ceramic-packaged parallel Flash from another vendor.
What the 150 ns access time means for the bus
The 150 ns access time governs how quickly data appears on the bus after the address is latched and chip enable is asserted. A host controller running at 8 MHz or slower can typically read back-to-back without wait states.
