2Gbit parallel NOR flash in a 64-LBGA footprint
The MT28FW02GBBA1HPC-0AAT is a 2Gbit parallel NOR flash organized as 128M x 16, housed in a 64-LBGA package measuring 11x13 mm. The 0.80 mm ball pitch demands a four-layer PCB for clean fan-out of the address and data buses — two-layer boards will struggle to route the full 16-bit data path without vias under the BGA. The wide range simplifies the power tree in mixed-voltage designs — the flash sits on whichever bus the controller provides, as long as it stays within that window.
That covers under-hood and cabin-mounted ECUs where the enclosure sees 85°C continuous with 105°C peaks during hot-soak. The 105 ns access time and 60 ns write-cycle time hold across the entire temperature band — no speed derating at the high end.
