Infineon Technologies S29GL01GS11DHB010

Overview

S29GL01GS11DHB010 from Infineon is a 1 Gb (128 MB) parallel NOR flash memory IC with 16-bit data bus, 65 nm MIRRORBIT™ Eclipse process, 3.0 V core supply (2.7–3.6 V), and industrial temperature grade (–40°C to +85°C). It delivers 90 ns random access time, 15 ns page access time, and integrated hardware ECC for single-bit error correction - deployed in boot code storage for industrial HMIs and network edge routers.

For engineers reviewing the S29GL01GS11DHB010 datasheet, S29GL01GS11DHB010 pinout, S29GL01GS11DHB010 application, or S29GL01GS11DHB010 equivalent, key selection criteria include asynchronous 16-bit parallel interface timing, sector-level erase granularity (128 kB), OTP array security, Versatile I/O voltage range (1.65–3.6 V), and AEC-Q100 Grade 3 qualification support.

Technical Context

This device implements an embedded algorithm controller (EAC) that executes autonomous program/erase operations without host CPU intervention. It supports three status monitoring methods - status register polling, data polling, and RY/BY# pin assertion - enabling deterministic timing control in real-time boot sequences.

The flash array is organized into uniform 128-kbyte sectors with advanced sector protection (ASP), supporting both volatile and non-volatile lock modes per sector. The 1024-byte OTP array includes two independently lockable regions for secure device configuration and cryptographic key storage.

FAQ

What is the minimum VIO voltage supported for reliable operation?

The S29GL01GS11DHB010 supports VIO down to 1.65 V across its full industrial temperature range. At this voltage, all timing parameters remain within specification, including tACC (90 ns max) and tPACC (15 ns max), provided VCC is maintained between 2.7 V and 3.6 V. This enables direct interfacing with 1.8 V logic families without level shifters.

Does this device require an external VPP supply for programming or erasing?

No. The S29GL01GS11DHB010 integrates on-chip charge pumps for programming and erase voltages. Only VCC (2.7–3.6 V) and VIO (1.65–3.6 V) supplies are required. This eliminates external high-voltage generation circuitry and simplifies power design for embedded systems with strict BOM constraints.

How is the 1024-byte OTP array accessed and secured?

The OTP array resides at a dedicated address range (0x0000_0000–0x0000_03FF) and is accessed using standard CFI-compliant commands. Each of its two 512-byte regions can be permanently locked via dedicated lock bits in the status register - once locked, no further writes or erases are possible, even after power cycle or reset.

Can sector protection be configured dynamically during runtime?

Yes. Advanced Sector Protection (ASP) supports both volatile (cleared on power cycle) and non-volatile (persistent) lock modes per sector. Volatile locks are set via command sequences and provide temporary protection during firmware updates; non-volatile locks require explicit unlock commands and persist through power cycles for permanent boot sector protection.
