Product details
Overview
S29GL032N11DFIV22 from Infineon Technologies (formerly Cypress) is a 32-Mbit, 16-bit-wide single-power-supply MirrorBit Flash memory IC with uniform sector architecture (64 × 64 KB sectors), 90 ns access time, and Secured Silicon Sector for factory-programmed 128-word electronic serial number. It operates from a single 3.0 V supply (2.7–3.6 V), supports JEDEC-compliant command set, and is used in embedded boot code storage for industrial controllers and network edge devices.
For engineers reviewing the S29GL032N11DFIV22 datasheet, S29GL032N11DFIV22 pinout, S29GL032N11DFIV22 application, or S29GL032N11DFIV22 equivalent, key selection criteria include uniform 64 KB sector erase granularity, VIO-referenced VersatileI/O™ (1.65–3.6 V), CFI compliance for host auto-configuration, and hardware write protection via WP#/ACC pin.
Technical Context
This device implements a 110 nm MirrorBit floating-gate NAND-like cell architecture enabling high-density, single-VCC flash operation. It uses hot-electron injection for programming and hot-hole assisted erase per sector, with full command-set compatibility to JEDEC JESD21-C and JESD22-A117 standards.
Internal state control logic manages autonomous erase/program cycles, while DQ7 data polling and RY/BY# output provide real-time status feedback. The Secured Silicon Sector is permanently locked post-factory and accessible only via dedicated unlock sequence, supporting secure firmware identity binding.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory density | 32 Mbit (2,097,152 words × 16-bit) |
| Access time | 90 ns at VCC = 2.7–3.6 V - determines minimum read cycle timing in microcontroller boot fetch |
| Sector architecture | 64 uniform 32 Kword (64 KB) sectors - enables deterministic erase scheduling without boot-sector exceptions |
| Write buffer size | 16-word (32-byte) page buffer - reduces multi-word programming overhead by batching writes |
| Data retention | 20 years typical - validated under JEDEC JESD22-A117, critical for unattended field deployments |
| Erase endurance | 100,000 cycles per sector - supports firmware update logging in industrial gateways |
| VIO range | 1.65–3.6 V - allows I/O voltage scaling independent of VCC for mixed-voltage SoC interfacing |
Pinout & Package
Package: 48-pin TSOP (Type I, standard thin small outline package, 12 × 20 mm body, 0.5 mm pitch).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A21 | Address inputs | 22-bit address bus supporting full 32 Mbit addressing; A-1 multiplexed with DQ15 in byte mode |
| DQ0–DQ15 | Data I/O | 16-bit bidirectional data bus; DQ15 functions as A-1 when BYTE# = low for 8-bit mode |
| CE#, OE#, WE# | Chip/Output/Write enable | Independent active-low controls allow interleaved read/write operations without bus contention |
| WP#/ACC | Write protect / accelerate | Logic-low asserts hardware sector lock; high-voltage input enables accelerated programming during production |
| RY/BY# | Ready/Busy output | Open-drain signal indicates active erase/program cycle completion - eliminates need for polling overhead |
| RESET# | Hardware reset | Asynchronous active-low input that terminates all operations and returns device to read mode - synchronizes boot firmware reload |
Key Features
| Feature | Design Value |
|---|---|
| Secured Silicon Sector | 128-word (256-byte) factory-programmed, permanently locked region containing unique electronic serial number for secure device identity |
| Program/Erase Suspend | Allows host to interrupt ongoing program/erase in one sector to read/program another - enables real-time firmware patching without halting system operation |
| CFI compliance | Enables automatic detection of device geometry, timing, and command set by host BIOS/bootloader - eliminates hard-coded flash initialization |
| Unlock Bypass mode | Reduces multi-word programming command overhead from 4 to 2 write cycles - improves firmware update throughput by ~30% |
| VersatileI/O™ control | VIO pin sets input threshold and output drive level independently of VCC - ensures reliable interface with 1.8 V or 3.3 V host logic |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S29GL032N90TFIV20 | Same die, 90 ns speed grade but in 48-ball fine-pitch BGA (VBK048) package - no TSOP footprint compatibility | Targeted for space-constrained PCBs where board area > thermal management priority | Select when layout requires BGA miniaturization and reflow profile supports 260°C peak temperature |
| MX29GL32EHXFI-90G | Macronix 32 Mbit flash with 90 ns access, identical TSOP-48 pinout, but lacks Secured Silicon Sector and CFI compliance | Suitable for cost-sensitive consumer electronics where secure identity and auto-detection are not required | Choose only if electronic serial number and host-agnostic initialization are unnecessary |
Compared with S29GL032N11DFIV22, the BGA variant offers identical functionality in smaller form factor but requires different layout and assembly; the Macronix alternative trades security and interoperability features for lower unit cost in non-critical applications.

FAQ
What is the function of the WP#/ACC pin on S29GL032N11DFIV22?
The WP#/ACC pin serves dual roles: when held low, it hardware-protects the first or last sector against accidental erase/program; when driven to 5.5 V (±0.3 V), it activates accelerated programming mode for faster factory throughput. Its behavior is defined in the datasheet's Section 8.16 and does not require external circuitry beyond a pull-up resistor for normal operation.
Does S29GL032N11DFIV22 support 8-bit data bus operation?
Yes - when the BYTE# pin is asserted low, the device operates in 8-bit mode: DQ0–DQ7 become the data bus, and DQ15 functions as A-1 for extended addressing. This mode is fully supported per Section 8.1 of the datasheet and maintains all timing specifications including 90 ns access time under valid VCC/VIO conditions.
How is the Secured Silicon Sector accessed and protected?
The Secured Silicon Sector is accessed only after issuing the dedicated Enter Secured Silicon Sector command sequence (six specific address/data writes). Once programmed and locked (via PPB lock bit), it becomes permanently read-only - no erase or program commands affect it. Factory programming of the 128-word ESN occurs before shipment and cannot be altered in the field.
What is the maximum operating temperature range for this part?
S29GL032N11DFIV22 is rated for industrial temperature range: –40°C to +85°C ambient. This is specified in Section 12 (Operating Ranges) of the datasheet and validated per JEDEC JESD22-A104 for temperature cycling and JESD22-A108 for high-temperature operating life.
