Product details
Overview
S29GL128S90DHA020 from Infineon is a 128 Mb (16 MB), 3.0 V core, parallel-interface MIRRORBIT™ Eclipse flash memory with ×16 data bus, 90 ns random access time, 15 ns page access time, and industrial temperature grade (–40°C to +85°C). It integrates hardware ECC for single-bit error correction, 128-kbyte uniform sector erase, and a 512-byte programming buffer-enabling fast firmware storage in automotive instrument clusters and industrial PLCs.
For engineers reviewing the S29GL128S90DHA020 datasheet, S29GL128S90DHA020 pinout, S29GL128S90DHA020 application, or S29GL128S90DHA020 equivalent, this device supports asynchronous XIP-capable read operations, Versatile I/O (1.65 V to VCC), suspend/resume during program/erase, and CFI-compliant software interface for bootloader and firmware update implementations.
Technical Context
The S29GL128S90DHA020 implements an asynchronous parallel interface with word-aligned addressing (A0–A22) and 16-bit bidirectional DQ bus. Its embedded algorithm controller (EAC) executes autonomous program/erase operations using command sequences compliant with Common Flash Interface (CFI) v1.4.
It features dual-voltage operation: 2.7–3.6 V core supply (VCC) and independent I/O voltage (VIO) from 1.65 V to VCC, enabling interoperability with mixed-voltage SoCs. Internal hardware ECC corrects single-bit errors on-the-fly during read, while status register polling and RY/BY# pin provide real-time operation monitoring.

Equivalent & Alternatives
The following parts are listed as comparable options for similar parallel NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S29GL128P90TFI020 | Same density and timing, but uses 64-ball LAE Fortified BGA (9 mm × 9 mm) instead of TSOP | Preferred for space-constrained PCBs where board area is prioritized over manual assembly | Select when footprint reduction and thermal performance outweigh hand-soldering needs |
| MX29GL128FPTI-90G | Macronix part with identical 128 Mb ×16, 90 ns access, but lacks integrated ECC and has no OTP array | Requires external error handling and separate key storage; lower cost for non-safety-critical use | Select only if ECC and secure OTP are not required, and BOM cost is primary constraint |
Compared with S29GL128P90TFI020, the TSOP package offers easier prototyping and rework; versus MX29GL128FPTI-90G, the Infineon part delivers certified reliability, built-in ECC, and AEC-Q100 qualification-critical for functional safety designs.

FAQ
Does S29GL128S90DHA020 support byte-level writes?
No. This device operates exclusively on word (16-bit) boundaries. All write operations-including single-word and buffer programming-require even-addressed 16-bit data transfers. Byte-level addressing or partial-word writes are not supported by the command set or hardware architecture.
What is the function of the STB pin on this device?
The STB (Strobe) pin is not present on the S29GL128S90DHA020. It appears only in the generic block diagram (Datasheet p.5) as a legacy reference; the actual 56-pin TSOP package omits STB. Pin count and signal list in Section 12.1 confirm CE#, OE#, WE#, RY/BY#, and RESET# as the sole control signals.
Can VIO be set to 1.8 V while VCC is at 3.3 V?
Yes. The Versatile I/O feature explicitly allows VIO from 1.65 V to VCC. At VCC = 3.3 V, VIO may be independently set to 1.8 V to interface directly with 1.8 V logic families-no level translation required-while maintaining full core functionality and timing specifications.
Is the 1024-byte OTP array field-programmable after soldering?
Yes. The OTP array is programmable in-system via standard CFI command sequences after mounting. Once locked (via dedicated lock bits), it becomes permanently read-only. Programming requires standard VCC/VIO supplies and valid command cycles-no special voltage or equipment is needed beyond normal flash operation.
