Frequently asked questions
Can I substitute a CY7C1011DV33 or CY7C1021DV33 for the CY7C0851AV-133AI?
No — the peers are single-port asynchronous SRAMs with different memory organization (128K × 16 and 64K × 16 versus this part's 64K × 36 dual-port synchronous interface). They are not pin-compatible, and the dual-port simultaneous access capability has no equivalent in those parts.
What package does the CY7C0851AV-133AI use, and is it reworkable?
The listed package is 176-LQFP (176-TQFP, 24×24 mm) in Bulk format. The 176-pin TQFP is a reworkable pad footprint, though the 24 mm body size means thermal mass is significant — hot-air rework is preferred over convective reflow touch-up.
What temperature grade and supply voltage does it carry?
Industrial -40 to 85 °C operating range on a 3.135–3.465 V supply. The narrow 3.3 V tolerance band is worth checking against the board's LDO regulation under dynamic load.
