Active 64Mbit parallel NOR flash for embedded code storage
The S29GL064S70BHI030 is an active-production 64Mbit parallel NOR flash from Infineon's GL-S series, organized as 8M x 8 or 4M x 16.
70 ns access, 2.7-3.6 V supply, parallel interface
The 70 ns access time sets the random-read ceiling — the host controller's wait-state configuration must accommodate this to avoid bus contention. The parallel memory interface uses a standard address/data multiplexed bus — no serial protocol overhead, which matters when the MCU's external bus controller expects a direct-mapped NOR footprint. Write-cycle time per word or page is 60 ns, matching the read speed for symmetric bus timing. Packaged in a 48-VFBGA with a 8.15 x 6.15 mm body, the footprint requires a 0.80 mm ball pitch — the PCB escape routing needs a via-in-pad or microvia layer stack to fan out the inner rows. Supplied in tray format, not tape-and-reel, so the pick-and-place feeder setup differs from reel-fed parts.
Industrial temp grade and RoHS3 compliance
The RoHS3 compliance covers the EU RoHS exemption list as of the latest revision — no additional substance restrictions beyond the standard 10 substances. Lifecycle status is Active — the manufacturer continues to support new designs and volume production.
