Product details

The CY7C1059DV33-12ZSXQ is an 8Mbit asynchronous SRAM from Infineon (formerly Cypress), organized as 1M x 8 and accessed through a parallel interface. Its 12 ns access time and matching 12 ns write cycle let it keep pace with moderate-speed microcontrollers and FPGAs without inserting wait states — useful for cache buffers, scratchpad memory, or data acquisition staging in industrial control and telecom equipment.

Supply and temperature — industrial range, 3.3 V rail

The 44-TSOP II package (0.400" body width, 10.16 mm) is a common footprint for mid-density asynchronous SRAMs, so PCB layout reuse across second-source candidates is straightforward.

Obsolete — no official successor listed

Infineon lists the CY7C1059DV33-12ZSXQ as Obsolete. No direct replacement order code is published in the lifecycle record, so buyers looking to fill a BOM line will need to source from independent distribution or qualified surplus stock.

Sourcing reality for a discontinued SRAM

Because this is an Obsolete part with no declared successor, new-design use is not recommended. For production support, the independent channel is the primary source.

Frequently asked questions

Is CY7C1059DV33-12ZSXQ obsolete?

Yes, Infineon lists the CY7C1059DV33-12ZSXQ as Obsolete. No official replacement order code has been published.

What is the replacement for CY7C1059DV33-12ZSXQ?

Infineon has not published an official successor for the CY7C1059DV33-12ZSXQ. For a pin-compatible alternative, look at other 44-TSOP II asynchronous SRAMs in the 8Mbit / 12 ns class from vendors like ISSI or Alliance Memory — verify the footprint and timing match your layout.

Is CY7C1059DV33-12ZSXQ same as CY7C1059DV33-12ZSXI?

The suffix difference typically indicates packaging or shipping medium variant. Both share the same base product number CY7C1059 and 44-TSOP II package. Confirm the exact specifications in the respective datasheets — the 'XQ' suffix on this part denotes Tube packaging.
