36Mbit synchronous SRAM — clocked at 250 MHz
The CY7C1440AV25-250BZXIT is a 36Mbit synchronous SRAM organized as 1M x 36, clocked at 250 MHz with a 2.6 ns access time. The 2.375V to 2.625V supply rail requires a clean 2.5V rail — the tolerance is tight enough that a standard ±5% regulator may need adjustment. Industrial temperature range (-40°C to 85°C) qualifies it for outdoor telecom, motor-drive control, and other thermally demanding environments where commercial-grade SRAM would drift out of spec.
Housed in a 165-ball FBGA (15x17 mm) — the 1.0 mm ball pitch is standard for four-layer fan-out; a two-layer board will struggle to escape the inner rows. The tape-and-reel packaging indicates reel quantity for automated pick-and-place. The synchronous SDR interface uses a single clock edge for all address and control signals, simplifying timing closure compared to double-data-rate parts.
Infineon lists the CY7C1440AV25-250BZXIT as Obsolete. Sourcing is through independent distribution — quantities are lot-specific and confirmed at RFQ.
