Product details

Overview

S29GL032N11FFIS32 from Infineon Technologies (formerly Cypress) is a 32-Mbit, 3.0-V single-power-supply MirrorBit Flash memory organized as 2,097,152 words (4,194,304 bytes), featuring 64 KB uniform sectors (64 sectors total), 90 ns access time, and 100,000 erase cycles per sector. It operates with VIO from 1.65 V to VCC and supports 16-bit or byte-wide (via BYTE#) data bus configuration in embedded boot code and firmware storage applications.

For engineers reviewing the S29GL032N11FFIS32 datasheet, S29GL032N11FFIS32 pinout, S29GL032N11FFIS32 application, or S29GL032N11FFIS32 equivalent, key selection criteria include JEDEC-compliant command set, Secured Silicon Sector with factory-programmed 128-word ESN, Advanced Sector Protection (Persistent and Password modes), CFI compliance, and support for Program/Erase Suspend & Resume functionality.

Technical Context

This device implements a 110 nm MirrorBit floating-gate architecture enabling simultaneous hot-hole erase and hot-electron programming across full sectors. Its VersatileI/O™ control decouples I/O voltage (VIO) from core supply (VCC), allowing interface compatibility with 1.8 V or 3.3 V host logic while maintaining 3.0 V internal operation.

The command-set architecture supports CFI interrogation, Autoselect mode for device identification, and hardware-accelerated programming via WP#/ACC input. Erase and program operations are status-monitored via DQ7 polling, DQ6/DQ2 toggling, or RY/BY# output - all fully compliant with JEDEC Standard JESD21-C.

Key Specifications

Equivalent & Alternatives

The following parts are listed as comparable options for similar Flash memory applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
S29GL032N10TFI020	Same die, 48-pin TSOP package (not BGA); 110 ns access time at VIO = 1.65–3.6 V.	Lacks fine-pitch BGA footprint; suited for through-hole or legacy PCB layouts.	Select when board space permits TSOP and lower-speed access suffices for cost-sensitive designs.
MX29GL320EHTI-90G	Macleod Semiconductor part; 90 ns access, same density, but no Secured Silicon Sector or Password Protection.	Supports basic firmware storage only - not suitable for secure boot or tamper-evident applications.	Choose only if security features are unnecessary and JEDEC command compatibility is sufficient.

Compared with S29GL032N11FFIS32, the TSOP variant trades BGA miniaturization and speed for ease of assembly, while the Macleod alternative omits critical security IP - making the Infineon part uniquely qualified for certified embedded systems requiring traceable, locked identity and protected firmware.

FAQ

What is the function of the WP#/ACC pin on S29GL032N11FFIS32?

The WP#/ACC pin serves dual roles: when driven low, it hardware-protects the first or last sector regardless of software protection settings; when driven high with elevated voltage (VHH ≈ 11.5 V), it enables accelerated programming for faster factory throughput. This pin is electrically isolated from VCC and requires external voltage control during ACC mode.

Does S29GL032N11FFIS32 support both x8 and x16 data bus widths?

Yes - the BYTE# input selects bus width: logic low configures the device for 16-bit operation (DQ0–DQ15 active), while logic high enables 8-bit mode (DQ0–DQ7 only), with DQ15 repurposed as A-1. This flexibility allows direct interfacing with either 8-bit or 16-bit microcontrollers without external glue logic.

How is the Secured Silicon Sector protected and accessed?

The Secured Silicon Sector is a dedicated 128-word (256-byte) region pre-programmed with a unique 8-word Electronic Serial Number at the factory. Access requires executing the Enter Secured Silicon Sector command sequence (0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00); once locked, no further writes are possible - even under VCC brownout or reset conditions.

Can S29GL032N11FFIS32 be used in systems requiring CFI-compliant auto-detection?

Yes - the device fully implements the Common Flash Interface (CFI) specification. By issuing the CFI Query command (0x98), the host reads a standardized 512-byte parameter table from address 0x0055, enabling automatic identification of geometry, command sets, and timing parameters - essential for generic flash drivers in Linux or RTOS environments.
