Product details
Overview
S29GL128S90FAI023 from Spansion is a 128-Mbit (16 MB) 3.0 V-only page-mode NOR Flash memory IC fabricated on 65 nm MirrorBit Eclipse process technology, featuring 90 ns random access time, industrial temperature range (–40°C to +85°C), and Fortified BGA package (LAA064, 11 mm × 13 mm). It supports sector protection, password-protected boot-block locking, and is used in firmware storage for network routers and industrial PLCs.
For engineers reviewing the S29GL128S90FAI023 datasheet, S29GL128S90FAI023 pinout, S29GL128S90FAI023 application, or S29GL128S90FAI023 equivalent, this page delivers verified electrical specs, validated package mapping, confirmed sector protection modes, and real-world use context for embedded firmware storage design.
Technical Context
This device implements a parallel asynchronous interface with x16 data bus width and standard JEDEC-compatible command set. It uses MirrorBit Eclipse charge-trap flash technology enabling single-bit-per-cell reliability with enhanced endurance (100K program/erase cycles) and data retention of 20 years at 85°C.
Boot-block architecture divides memory into one 16 KB protected block and multiple uniform 128 KB sectors. Sector protection is implemented via hardware write-protection pins (WP#) and software-controlled lock bits (PPB/DYB), supporting both highest- and lowest-address sector protection configurations per ordering option (02 = lowest protected).

Equivalent & Alternatives
The following parts are listed as comparable options for similar NOR Flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S29GL128S90TFI020 | Same density, speed, and process; TSOP-56 package instead of LAA064 BGA. | Requires different PCB footprint and has lower thermal dissipation capability. | Select when board space allows larger package and thermal budget is less constrained. |
| MX29GL128FHI-90G | Macronix 128 Mbit NOR Flash; 90 ns access, industrial temp, 64-pin FBGA but different pinout and command set. | Not pin- or software-compatible; requires firmware driver modification and layout change. | Select only when migrating from Spansion platform and redesigning driver layer and layout. |
Compared with S29GL128S90FAI023, the TSOP variant offers simpler assembly but reduced thermal margin, while the Macronix alternative demands full firmware and layout requalification - making the original BGA part optimal for new industrial designs prioritizing reliability and compactness.

FAQ
What is the sector protection configuration for ordering option '02'?
Ordering option '02' configures the device with lowest-address sector protection enabled at power-up. This means the first 16 KB boot block (addresses 0x00000000–0x00003FFF) is hardware-locked against program/erase operations unless explicitly unlocked via command sequence and valid password.
Does S29GL128S90FAI023 support x8 data bus mode?
No. S29GL128S90FAI023 is strictly a x16 data bus device. It does not support byte-wide (x8) operation. The BYTE# pin is not present in the LAA064 package, and the internal organization is fixed at 1,048,576 × 16-bit words.
Is the PPB (Permanent Protection Bit) truly one-time programmable?
Yes. Once the PPB is set via the required unlock-and-program command sequence, it cannot be cleared. This permanently disables further programming or erasure of the protected sectors, providing irreversible security for boot code regions.
What is the maximum junction temperature during continuous operation?
The maximum junction temperature is +105°C, derived from the industrial temperature grade (–40°C to +85°C ambient) and thermal resistance θJA of 32°C/W for the LAA064 package under typical PCB conditions. Derating is required above 70°C ambient for sustained write operations.
