The 32-bit data bus matches a 32-bit RISC or DSP memory port without external muxing — one read per clock cycle at full speed. Supply range is 3.15 V to 3.6 V, placing it in the 3.3 V nominal logic family. The industrial temperature grade spans -40°C to +125°C, covering engine-bay, outdoor telecom cabinet, and factory-floor ambient conditions without forced cooling. ## Obsolete — last-time-buy window closed; sourced through surplus channels For sustainment programs that cannot respin the board, the part remains available on a quoted-to-order basis. The 100-lead TQFP (14 x 20 mm body, 0.5 mm pitch) is a standard fine-pitch quad flat pack. The 32-bit data bus fans out to the outer rows; the inner rows carry address and control. Supplied in Tape & Reel (TR) — the reel quantity is the standard TQFP-100 carrier. The moisture sensitivity level (MSL) for this package body is typical of 100-TQFP; bake before reflow if the floor-life exposure has been exceeded.","metaTitle":"Infineon CY7C1339G-133AXET 4Mbit SRAM, 133 MHz, 100-TQFP","metaDescription":"Obsolete 4Mbit synchronous SRAM, 128K x 32, 133 MHz clock, 4 ns access, -40 to +125°C.
