256K x 16 asynchronous SRAM with 10 ns access
The CY7C1041GE30-10BVXI is a 4 Mbit asynchronous SRAM organized as 256K words by 16 bits — the x16 data bus matches 16-bit microcontrollers and DSPs that need a single-chip data memory without byte-lane multiplexing. Industrial temperature range (-40°C to 85°C) qualifies the part for factory-floor controllers, outdoor telecom base stations, and automotive infotainment that does not require AEC-Q100 certification.
48-ball VFBGA — footprint and assembly
The 48-VFBGA package (6x8 mm body, 0.75 mm ball pitch) is a fine-pitch BGA that requires a controlled solder-paste stencil and X-ray inspection after reflow — the 0.5 mm ball diameter and 0.25 mm solder-mask-defined pad are standard for 4-layer boards. Because the package is a VFBGA (very fine-pitch BGA), the moisture sensitivity level (MSL) is typically 3 — bake before reflow if the floor life is exceeded, per J-STD-033.
