It belongs inside an indoor, climate-controlled chassis — office equipment, telecom line cards in a conditioned central office, or benchtop instrumentation. Not suitable for an engine bay, rooftop enclosure, or factory floor without active cooling and environmental sealing.
144-LQFP (20x20 mm body). Surface mount, reflow soldering required.
The 32K x 36 organization provides 32 data bits plus 4 bits typically used for parity or ECC, allowing a 32-bit host to read or write a full word plus integrity check in a single 12 ns cycle. It is common in DSP coefficient storage, wide FIFO buffers, and dual-processor shared memory.
The CY7C057V-12AXCT is supplied in a 144-lead LQFP (20x20 mm body, 0.5 mm pitch), also designated as 144-TQFP (20x20). It is a surface-mount package requiring reflow soldering.
