Infineon Technologies S29GL256S10TFB010

Overview

S29GL256S10TFB010 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 and 15 ns page access, and integrates hardware ECC for single-bit error correction-enabling reliable code storage in automotive instrument clusters and industrial HMI boot memory.

For engineers reviewing the S29GL256S10TFB010 datasheet, S29GL256S10TFB010 pinout, S29GL256S10TFB010 application, or S29GL256S10TFB010 equivalent, key selection criteria include its 128 kB uniform sector erase granularity, 512-byte write buffer throughput (1.5 MBps), Versatile I/O support (1.65 V to VCC), 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), supports page-mode reads within 32-byte aligned pages, and uses embedded algorithms for sector erase and buffered programming. Its internal state machine handles command execution without external timing control.

The integrated ECC engine operates transparently during read cycles, correcting single-bit errors in real time using dedicated syndrome logic and spare bytes per sector. Sector protection includes both volatile (lock bits) and non-volatile (ASP register) methods, plus a separate 1024-byte OTP array with dual lockable regions.

FAQ

What is the minimum VIO voltage supported by S29GL256S10TFB010?

The device supports VIO from 1.65 V to VCC, enabling direct interface with 1.8 V host processors without level shifters. This Versatile I/O feature is confirmed in the datasheet Section 1.2 and Table 2-1, and applies across all operating temperatures and densities in the GL-S family.

Does S29GL256S10TFB010 require external ECC circuitry?

No. It includes an integrated hardware ECC engine that automatically detects and corrects single-bit errors during read operations using spare bytes per sector. The ECC logic is transparent to the host and requires no software intervention or external components, as specified in Section 5.3 and Table 5-1 of the datasheet.

Can S29GL256S10TFB010 be used in AEC-Q100 Grade 2 automotive applications?

Yes. The "TFB010" suffix denotes AEC-Q100 Grade 2 qualification (–40°C to +105°C), validated per the standard's stress test requirements. This is explicitly stated in the "Temperature range / grade" section of the datasheet and confirmed in the ordering information table (Section 13.3).

What package type does S29GL256S10TFB010 use?

S29GL256S10TFB010 uses a 64-ball LAE Fortified BGA package (9 mm × 9 mm, 0.8 mm pitch), as defined in Section 12.2 of the datasheet. This package offers improved thermal performance and board-level reliability compared to TSOP variants, especially under thermal cycling conditions.
