8 ns asynchronous SRAM — bus timing headroom for the system architect
The Cypress CY7C1041CV33-8ZSXI is a 4Mbit asynchronous SRAM organized as 256K x 16 bits. Its 8 ns access time means the data appears on the bus within 8 ns of the address being valid — fast enough to interface with a 100 MHz-class processor without wait states, assuming typical board delays. The parallel interface is straightforward to hook up to any MCU or FPGA with a memory controller, no configuration needed.
Package and footprint — 44-TSOP II
The device comes in a 44-TSOP II package, a standard surface-mount footprint measuring 10.16 mm body width. It ships in a tray. The mounting type is Surface Mount. For a layout engineer, the 44-TSOP II is a common pinout for 256K x 16 asynchronous SRAMs, so a board designed for this part can often accept a drop-in alternate from another vendor — but always check the pin 1 orientation and any NC pins against the target alternate's datasheet.
