It is a volatile memory, parallel interface, and operates from a single 3V to 3.6V supply. ## 20 ns access time and bus timing The 20 ns access time sets the read-cycle ceiling for the bus. When the host controller's address-to-data setup requirement is, say, 15 ns, this part leaves 5 ns of margin before the controller samples the data. That margin shrinks with temperature and supply droop, so the buyer should confirm the worst-case timing budget against the controller datasheet — especially if the board runs at the upper temperature limit. ## Package and footprint check The part is supplied in a 44-TSOP II package (0.400-inch body width, 10.16 mm wide, 0.8 mm lead pitch). This is a legacy JEDEC MO-142 footprint — common on 1990s–2000s board designs. If you are retrofitting an existing board, verify that the land pattern matches the TSOP II variation; the 44-TSOP II is not pin-compatible with the older 44-TSOP I (0.5 mm pitch). The package is delivered in trays. The base product number is CY7C1041, and the suffix encodes the voltage (CV33 = 3.3V), speed (20 = 20 ns), package (ZS = 44-TSOP II), and temperature range (XA = industrial).","metaTitle":"CY7C1041CV33-20ZSXA 4Mbit Async SRAM – 20 ns, 44-TSOP II","metaDescription":"Infineon CY7C1041CV33-20ZSXA 4Mbit asynchronous SRAM, 256K x 16, 20 ns access, 3V–3.6V, -40°C to 85°C, 44-TSOP II.
