128 Mbit parallel NOR flash for automotive code storage
The Infineon S29GL128S10DHB020 is a 128 Mbit parallel NOR flash memory from the Automotive GL-S series, organized as 8M x 16 bits.
Access time and write-cycle budget
With a 100 ns access time, this part supports zero-wait-state reads from a 10 MHz bus clock and can stretch to higher frequencies with a single wait state inserted by the memory controller. The 60 ns write cycle time (word/page) means a full 128-word page buffer fills in under 4 µs, which then programs in a single embedded algorithm cycle — useful for OTA firmware updates where the total write time is dominated by the page program sequence, not the bus transfer.
Package and board integration
Housed in a 64-ball FBGA (9x9 mm) package, the 0.8 mm ball pitch allows a 4-layer PCB with microvias to fan out all signal and supply balls without blind vias.
RoHS3 compliant (2011/65/EU + 2015/863). The AEC-Q100 qualification includes the full Grade 1 temperature sweep and reliability stress sequence — the part ships with lot traceability and the manufacturer's standard warranty through authorized distribution.
