12 ns asynchronous SRAM — 512K x 16, 3.3 V, industrial temp
The Infineon CY7C1051DV33-12ZSXI is an 8 Mbit asynchronous SRAM organized as 512K words by 16 bits, with a 12 ns access time that sets the bus timing margin for a 16-bit data bus running at typical MCU/MPU clock rates.
Parallel interface and package fit
The parallel memory interface connects directly to the MCU or MPU address and data buses — no serial-to-parallel conversion latency, which matters when the CPU fetches instructions or data in back-to-back cycles. Housed in a 44-TSOP II package (0.400-inch body width, 10.16 mm), the surface-mount footprint suits standard reflow assembly.
