Infineon Technologies S29GL256S10FHIV10

Overview

S29GL256S10FHIV10 from Infineon is a 256 Mb (32 MB) parallel NOR flash memory IC with 16-bit data bus, fabricated on 65 nm MIRRORBIT™ Eclipse process. It operates from a single 2.7–3.6 V supply, delivers 90 ns random access time and 15 ns page access time, and integrates hardware ECC for single-bit error correction. It is used in boot code storage for industrial microcontrollers requiring fast XIP execution and reliable non-volatile firmware retention.

For engineers reviewing the S29GL256S10FHIV10 datasheet, S29GL256S10FHIV10 pinout, S29GL256S10FHIV10 application, or S29GL256S10FHIV10 equivalent, key selection criteria include its 128 kB uniform sector erase granularity, 512-byte programming buffer throughput (1.5 MBps), Versatile I/O support (1.65–3.6 V), and AEC-Q100 Grade 2 qualification (–40°C to +105°C).

Technical Context

This device implements an asynchronous parallel interface with word-aligned addressing (A0–A23), supporting both standard read and 32-byte page-mode reads. Its embedded algorithm controller (EAC) manages autonomous program/erase operations, status reporting via RY/BY# pin or status register, and suspend/resume capability during active operations.

The internal architecture includes separate secure silicon region (1024-byte OTP with dual lockable sectors), advanced sector protection (volatile/non-volatile), and CFI-compliant parameter table for host software identification. ECC logic operates transparently during read cycles without CPU intervention.

FAQ

Is S29GL256S10FHIV10 pin-compatible with earlier S29GL256N or S29GL256P variants?

No. While functionally similar, S29GL256S introduces updated command set enhancements, revised timing parameters (e.g., tPACC = 15 ns vs. 25 ns), and added features like enhanced OTP locking. Pinout remains identical for same package type (e.g., 56-pin TSOP), but firmware must be validated against the S revision command table and timing specifications.

Does the hardware ECC correct errors during program or erase operations?

No. Hardware ECC operates exclusively during read operations to detect and correct single-bit errors in retrieved data. It does not apply to programming or erasing - those operations rely on internal verify algorithms and status flag reporting (e.g., P/E failure bits in status register) rather than ECC correction.

Can the Versatile I/O feature support mixed-voltage operation where VCC = 3.3 V and VIO = 1.8 V simultaneously?

Yes. The device explicitly supports independent VCC (2.7–3.6 V) and VIO (1.65–3.6 V) supplies. With VCC = 3.3 V and VIO = 1.8 V, input thresholds adapt to 1.8 V logic levels while core logic runs at 3.3 V, enabling direct interface with 1.8 V FPGAs or application processors without external level shifters.

What happens to the RY/BY# pin during a suspended erase operation?

During suspension, RY/BY# transitions high to indicate readiness for read commands, but the internal erase operation remains paused. After resuming, RY/BY# goes low again until completion. This behavior enables time-critical reads (e.g., sensor polling) without aborting or restarting the erase cycle - confirmed in Section 5.5 of the datasheet.
