Spansion S29GL512S10DHA020

Overview

S29GL512S10DHA020 from Infineon is a 512 Mb (64 MB) parallel NOR flash memory IC with 16-bit data bus, 3.0 V core supply (2.7–3.6 V), and 15 ns page access time. It features hardware ECC for single-bit error correction, 128 kB uniform sector erase, and a 512-byte write buffer enabling 1.5 MBps buffered programming. Used in boot code storage for industrial microcontrollers requiring XIP capability and high reliability.

For engineers reviewing the S29GL512S10DHA020 datasheet, S29GL512S10DHA020 pinout, S29GL512S10DHA020 application, or S29GL512S10DHA020 equivalent, key selection criteria include its asynchronous 16-bit interface, Versatile I/O (1.65–VCC), AEC-Q100 Grade 2 qualification (–40°C to +105°C), 100,000 program/erase cycles, and CFI-compliant software interface.

Technical Context

This device implements an embedded algorithm controller (EAC) that executes autonomous program and erase operations without host CPU intervention. Its MIRRORBIT™ Eclipse architecture on 65 nm process enables simultaneous read-while-suspend during programming or erasing, supported by status register polling, RY/BY# pin signaling, and data polling mechanisms.

The flash array is organized into uniform 128 kB sectors with advanced sector protection (ASP) offering both volatile and non-volatile lock bits per sector. A dedicated 1024-byte OTP array includes two lockable regions for secure configuration storage, and the device supports Common Flash Interface (CFI) parameter tables for runtime identification and command set discovery.

FAQ

Does S29GL512S10DHA020 support synchronous read or burst mode?

No. This device is strictly asynchronous-no clock input is required or supported. All read operations use CE#, OE#, and address setup/hold timing per datasheet AC specifications. Page mode read provides faster subsequent accesses within the same 32-byte page, but it remains asynchronous and does not rely on clock edges or burst counters.

Can VIO be set to 1.8 V while VCC is at 3.3 V?

Yes. The Versatile I/O feature explicitly supports VIO from 1.65 V to VCC. At VCC = 3.3 V, VIO may be independently set to 1.8 V to interface with 1.8 V logic families, provided all timing parameters (e.g., tVEX, tVDS) are met per the "VersatileIO" column in the Performance Summary table.

Is the 1024-byte OTP array field-programmable after soldering?

Yes. The OTP array is programmable in-system using standard command sequences (e.g., unlock + program commands). Each of the two lockable regions can be permanently locked once written, preventing further modification-ideal for storing calibration data or cryptographic keys during final test or field provisioning.

What happens during power loss while a sector erase is in progress?

The device includes hardware data protection during power-off: if VCC drops below the reset threshold during erase, the embedded algorithm controller aborts the operation and restores valid data from the last known good state. No partial or corrupted sector results-only the incomplete erase is canceled, preserving prior contents.
