Product details

Overview

S29GL256S11DHV020 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-used in boot code storage and firmware update storage in industrial controllers.

For engineers reviewing the S29GL256S11DHV020 datasheet, S29GL256S11DHV020 pinout, S29GL256S11DHV020 application, or S29GL256S11DHV020 equivalent, key selection criteria include its 128 kB uniform sector erase granularity, 512-byte write buffer throughput (1.5 MBps), Versatile I/O support (1.65–3.6 V), OTP array, and AEC-Q100 Grade 2 qualification.

Technical Context

This device implements an asynchronous parallel interface with word-aligned addressing (A0–A23), supporting both standard and page-mode reads. Its embedded algorithm controller handles program/erase operations autonomously, with suspend/resume capability and status reporting via status register, data polling, or RY/BY# pin.

The architecture includes dedicated sectors with Advanced Sector Protection (volatile/non-volatile lock), a 1024-byte one-time-programmable (OTP) array split into two lockable regions, and Common Flash Interface (CFI) compliance for host software identification and configuration.

Equivalent & Alternatives

The following parts are listed as comparable options for similar parallel NOR flash memory applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
S29GL256P11DHV020	Same density and package, but uses older 90 nm process; slower 110 ns random access	Lacks Versatile I/O (fixed VIO = VCC); incompatible with mixed-voltage designs	Select only if legacy compatibility or cost sensitivity outweighs performance and flexibility needs
MX29GL256FHI-90G	Micron part with 90 ns access, no integrated ECC; requires external error handling	Supports same TSOP/BGA packages but lacks OTP array and ASP granularity	Prefer when board space permits external ECC logic and firmware does not require secure OTP storage

Compared with S29GL256P11DHV020 and MX29GL256FHI-90G, the S29GL256S11DHV020 uniquely combines 65 nm efficiency, hardware ECC, Versatile I/O, and dual-lock OTP-making it optimal for new designs demanding reliability, security, and voltage flexibility.

FAQ

What temperature grades are available for S29GL256S11DHV020?

This part is offered in Industrial Plus (–40°C to +105°C) and Automotive AEC-Q100 Grade 2 (–40°C to +105°C) variants. The "H" in the ordering code denotes the +105°C rating, and "V" indicates VBU BGA packaging. Both grades share identical electrical specs and timing performance.

Does S29GL256S11DHV020 support burst or synchronous read modes?

No-it is strictly asynchronous and does not support clocked or burst read protocols. All read operations are initiated by CE#, OE#, and address setup; timing is governed by tACC, tPACC, and tOE specifications. Page-mode reads accelerate intra-page access but remain asynchronous.

Can the OTP array be reprogrammed after locking?

No. Once either of the two OTP regions is permanently locked via the appropriate CFI command sequence, its contents become read-only and irreversible. Unlocking is not supported-even with hardware reset or power cycle-ensuring cryptographic key or calibration data immutability.

How is sector protection configured on this device?

Sector protection is managed through Advanced Sector Protection (ASP), supporting both volatile (cleared on power cycle) and non-volatile (persistent) lock bits per 128 kB sector. Configuration uses standard CFI commands and can be controlled via status register writes or hardware WP# pin assertion, enabling flexible field-update policies.
