What the 60 ns access time means on the bench
The Infineon S29JL064J60TFI000 is a 64 Mbit parallel NOR flash in the JL-J series, organized as 8M x 8 or 4M x 16. The 60 ns access time means the part can deliver data within 60 ns of the address being stable — fast enough for most legacy 8- or 16-bit microcontroller buses without inserting wait states at typical clock speeds up to around 16 MHz. If your controller runs faster than that, you will need to account for the access time in the bus timing budget.
Housed in a 48-TFSOP (0.724", 18.40 mm width) surface-mount package, the S29JL064J60TFI000 is supplied in a tray. The 48-TSOP footprint is a standard parallel NOR flash layout — if your board already has a footprint for a 48-pin TSOP with 0.5 mm pitch, this part drops in without a layout change.
