Obsolete — sourcing for production or repair
For new designs, a pin-compatible or functionally equivalent replacement should be identified.
10 ns access time — bus timing margin
The write cycle time matches the read at 10 ns, so back-to-back operations run at full speed. For a processor running at 66 MHz or slower, the 10 ns part provides healthy timing margin; at 100 MHz it is right at the edge — check the controller's tCO and board trace delay before committing the layout.
16 Mbit in 2M x 8 — memory map fit
Organized as 2M words of 8 bits, this part suits byte-wide data buses common in 8-bit and 16-bit microcontrollers, DSPs, and legacy ASIC interfaces. The 16 Mbit density fits medium-sized code or data buffers — think boot code, lookup tables, or packet buffers in networking gear. The parallel interface uses 21 address lines and 8 data lines; verify that your processor or FPGA has enough GPIO or memory-controller pins before routing.
48-VFBGA (8x9.5 mm) — layout and assembly
The 48-ball VFBGA package measures 8x9.5 mm with a fine-pitch ball array. This footprint demands a multi-layer PCB with microvias or blind vias for fan-out.
Supply and temperature range
Runs from 3.0 V to 3.6 V, making it a 3.3 V nominal part — common for late-2000s system-on-chip and FPGA designs. If your system sees sustained 85°C ambient, derate the supply current per the datasheet's thermal curve; the 48-VFBGA's small footprint limits heat dissipation without airflow.
