Product details
Overview
S29GL032N11TFIV20 from Infineon Technologies (formerly Cypress) is a 32-Mbit, 16-bit-wide single-power-supply MirrorBit Flash memory 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 industrial control systems.
For engineers reviewing the S29GL032N11TFIV20 datasheet, S29GL032N11TFIV20 pinout, S29GL032N11TFIV20 application, or S29GL032N11TFIV20 equivalent, key selection criteria include uniform sector erase capability, Secured Silicon Sector with factory-programmed 128-word ESN, CFI compliance for host auto-configuration, and hardware reset (RESET#) support for system boot recovery.
Technical Context
This device implements a 110 nm MirrorBit floating-gate NOR Flash architecture with hot-hole assisted erase and hot-electron injection programming. It uses separate CE#, WE#, and OE# controls, supports byte/word configuration via BYTE# input, and features VersatileI/O™ where all signal levels are referenced to VIO (1.65–3.6 V).
Command execution is latch-based: addresses and data for program/erase operations are internally latched during standard microprocessor write cycles. Status monitoring relies on DQ7 polling, DQ6 toggle bits, or RY/BY# output - no external timing dependencies required for operation completion detection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory density | 32 Mbit (2,097,152 × 16-bit words); enables compact firmware storage without external address multiplexing |
| Access time | 90 ns at VCC = 2.7–3.6 V; meets real-time boot latency requirements in deterministic embedded systems |
| Page read time | 25 ns for 8-word buffer; reduces instruction fetch overhead during sequential code execution |
| Erase endurance | 100,000 cycles per sector; supports field firmware update cycles over 10+ years of operation |
| Data retention | 20 years at 125°C; qualified for extended-life industrial and automotive under-hood applications |
| Supply voltage | Single 3.0 V supply (2.7–3.6 V); eliminates need for dual-rail power design in host MCU subsystems |
| Secured Silicon Sector | 128-word (256-byte) factory-lockable region with 8-word ESN; provides immutable device identity for secure boot validation |
Pinout & Package
Package: 48-pin TSOP (Type I, standard thin small outline package), 12 × 20 mm body, lead pitch 0.5 mm. Pin compatibility maintained across S29GL-N family for drop-in replacement within same package variant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A20 | Address inputs | 21-bit address bus supporting full 32 Mbit addressing; A-1 (DQ15/A-1) functions as LSB address in word mode |
| DQ0–DQ15 | Data/address bidirectional I/O | 16-bit data bus; DQ15 doubles as A-1 in word mode; supports byte access when BYTE# = low |
| CE# | Chip enable | Active-low chip select; device enters standby when CE# high, enabling multi-device memory mapping |
| WE# | Write enable | Controls write strobe timing; latches command sequences and data during programming/erase setup |
| OE# | Output enable | Enables output drivers during read; allows shared bus operation with other peripherals |
| RESET# | Hardware reset | Aborts ongoing operation and returns device to read mode; synchronizes boot firmware access after power-up |
| RY/BY# | Ready/Busy indicator | Open-drain active-low output signaling program/erase completion; eliminates software polling overhead |
| WP#/ACC | Write protect / accelerate | Protects first/last sector when low; applies high-voltage ACC during programming to reduce cycle time by ~30% |
Key Features
| Feature | Design Value |
|---|---|
| CFI compliance | Enables automatic flash detection and parameter loading by host BIOS/bootloader without hard-coded timing tables |
| Program Suspend/Resume | Allows interrupting a sector program to read boot code from another sector - critical for fail-safe firmware updates |
| Erase Suspend/Resume | Permits pausing bulk erase to service real-time interrupts or validate partial firmware writes before continuation |
| Advanced Sector Protection | Combines persistent lock bits and password-based protection to prevent unauthorized firmware modification in deployed systems |
| Secured Silicon Sector | Factory-programmed 128-word region with permanent lock; stores cryptographic keys or unique identifiers resistant to field reprogramming |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NOR Flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S29GL032N10TFIV20 | 110 ns access time (vs. 90 ns); identical sector architecture and command set | Lower performance grade suitable for non-real-time firmware storage where <90 ns latency not required | Select for cost-sensitive designs with relaxed boot timing budgets |
| MX29GL32EHXFI-90G | Same 32 Mbit density, 90 ns access, but uses Macronix's MXSMIO interface instead of JEDEC CFI | Requires modified bootloader support; lacks Secured Silicon Sector and factory ESN | Choose only if existing design already uses MXSMIO ecosystem and secure identity is not required |
Compared with S29GL032N11TFIV20, the -10 variant trades speed for lower cost in static firmware roles, while the MX29GL32EHXFI-90G requires firmware-level interface changes and forfeits hardware-based device identity - making the Infineon part preferred for secure, timing-critical, or CFI-dependent systems.

FAQ
Is S29GL032N11TFIV20 pin-compatible with earlier S29GL032N variants in TSOP-48?
Yes - all S29GL032N TSOP-48 variants (including models ending in 'V20') share identical pinout, electrical characteristics, and command set. The '11' denotes 90 ns access speed, and 'V20' specifies the 48-pin TSOP package with lead-free finish and industrial temperature range (–40°C to +85°C). No PCB redesign is needed for migration.
Does this device support 8-bit data bus operation?
Yes - when BYTE# is driven low, the device operates in x8 mode using DQ0–DQ7 only, with A0–A20 interpreted as byte-addressed locations. This enables compatibility with 8-bit microcontrollers without external data bus demultiplexing, while retaining full 32 Mbit capacity through extended addressing.
What is the function of the WP#/ACC pin beyond write protection?
When a 5.5 V ±0.3 V voltage is applied to WP#/ACC during programming, it activates accelerated programming mode, reducing individual word program time by approximately 30%. This feature is intended for high-throughput manufacturing but remains functional in-field for rapid firmware patching where timing margins allow.
How is the Secured Silicon Sector protected from accidental overwrite?
The Secured Silicon Sector is locked permanently via fuse-based PPB (Persistent Protection Bit) programming. Once the PPB is set, no command sequence - including chip erase - can modify the 128-word region. Factory programming of the 8-word Electronic Serial Number occurs before PPB lock, ensuring immutable device identity throughout product life.
