Product details
Overview
S29GL032N11FFIV22 from Infineon Technologies (formerly Cypress) is a 32-Mbit, 16-bit-wide single-power-supply MirrorBit Flash memory IC organized as 2,097,152 words (4,194,304 bytes), featuring 90 ns access time, 25 ns page read time, and uniform sector architecture with sixty-four 32 Kword (64 KB) sectors. It operates from a single 3.0 V supply (2.7–3.6 V), supports JEDEC-compliant command set, and is used for boot code storage and firmware updates in embedded industrial controllers.
For engineers reviewing the S29GL032N11FFIV22 datasheet, S29GL032N11FFIV22 pinout, S29GL032N11FFIV22 application, or S29GL032N11FFIV22 equivalent, key selection criteria include sector protection mode (Persistent/Password), VIO voltage flexibility (1.65–3.6 V), Ready/Busy# status signaling, CFI compliance for host auto-configuration, and TSOP-48 package compatibility with legacy board layouts.
Technical Context
This device implements a synchronous command-based Flash architecture with hardware reset (RESET#), dedicated Ready/Busy# output, and dual-mode write protection via WP#/ACC input. Its 110 nm MirrorBit process enables hot-hole erase and hot-electron programming, supporting up to 100,000 erase cycles per sector and 20-year data retention.
The flexible I/O control uses VIO to define all input thresholds and output levels, enabling interoperability with mixed-voltage systems. Sector erase architecture isolates operations to individual 64 KB blocks, while Unlock Bypass mode reduces multi-word programming overhead to two write cycles instead of four.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 32 Mbit (2,097,152 × 16-bit words); sufficient for full bootloader + application firmware in space-constrained embedded designs |
| Access Time | 90 ns at VCC = 2.7–3.6 V; meets real-time boot latency requirements for industrial PLCs and motor drives |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S29GL032N10TFIV20 | 100 ns access time (vs. 90 ns); same 48-pin TSOP package and command set | Lower performance margin acceptable in non-real-time boot paths (e.g., set-top boxes) | Select when cost sensitivity outweighs 10 ns latency requirement and thermal derating is not critical |
| MX29GL32EHXFI-90G | Macronix part with identical density, 90 ns speed, and TSOP-48; lacks Secured Silicon Sector and Password Protection | Used where basic firmware storage suffices without cryptographic identity or anti-tamper features | Choose for price-driven consumer applications where advanced security features are unnecessary |
Compared with S29GL032N11FFIV22, the S29GL032N10TFIV20 trades 10 ns speed for lower cost in less timing-critical systems, while the MX29GL32EHXFI-90G omits security features but offers broader distributor availability and simpler qualification.

FAQ
Is S29GL032N11FFIV22 pin-compatible with earlier Cypress S29GL032N variants?
Yes-this part retains identical 48-pin TSOP footprint, signal mapping, and electrical timing as legacy Cypress S29GL032N devices. The "FFIV22" suffix denotes Infineon's post-acquisition manufacturing revision with no functional or mechanical changes. All CE#, OE#, WE#, and RESET# timing parameters match Rev. *B datasheet specifications exactly.
Does S29GL032N11FFIV22 support 8-bit data bus operation?
Yes-asserting BYTE# low configures DQ0–DQ7 as an 8-bit data bus while DQ8–DQ15 become high-impedance. Address lines remain fully functional, and all command sequences operate identically. This mode is verified in Section 8.1 of the datasheet and supports legacy 8-bit microcontrollers without external glue logic.
What is the purpose of the WP#/ACC pin beyond write protection?
When driven to VHH (approximately 9–12 V), WP#/ACC activates accelerated programming mode, reducing single-word programming time by ~30% and improving throughput during high-volume system manufacturing. This function is disabled in standard 3.0 V operation and requires external voltage generation circuitry only in production test environments.
How does the Secured Silicon Sector differ from standard flash sectors?
The Secured Silicon Sector is a dedicated 256-byte region (128 words) that can be permanently locked at factory or by user command. Once locked, no further writes or erases are possible-even with valid passwords or unlock sequences. It is electrically isolated from main array erase algorithms and retains data independently, making it suitable for storing immutable device IDs or root keys.
