32 Mbit parallel NOR flash with 70 ns access
The S29JL032J70BHI320 is a 32 Mbit parallel NOR flash from Infineon's JL-J series, organized as 4M x 8 or 2M x 16 via byte-mode selection. The 70 ns access time means the processor reads the first word within one bus cycle at typical 3.3 V — no wait states for most 50–66 MHz bus controllers. NOR flash architecture supports execute-in-place (XIP) — the CPU fetches instructions directly from the flash without copying code to RAM first, saving the SRAM budget for data buffers.
Supply, temperature, and package for board integration
Housed in a 48-ball VFBGA (8.15 x 6.15 mm body, 0.80 mm ball pitch). Store the tray in a dry cabinet — the MSL level is not stated here, but BGA NOR flash typically ships at MSL 3, meaning a 168-hour floor life after the moisture barrier bag is opened.
