8Mbit asynchronous SRAM for buffer and scratchpad
The CY7C1051DV33-12ZSXIT is an 8Mbit asynchronous SRAM organized as 512K x 16 bits, with a 12 ns access time that sets the read-cycle floor for the bus timing budget.
Infineon lists the CY7C1051DV33-12ZSXIT as Obsolete. Confirm the package (44-TSOP II, 0.400-inch body width) and the 512K x 16 organization match your board before committing.
12 ns access and 16-bit bus for timing closure
The 12 ns access time and 12 ns write cycle time mean the SRAM can keep pace with a bus clocked at the access-time reciprocal without wait states, assuming the controller's output-hold timing has margin. The 16-bit wide data bus connects directly to a 16-bit MCU or DSP without byte-lane muxing.
