Product details
Overview
S29GL032N90FFIS42 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-compatible command set, and is used for boot code storage and firmware updates in industrial control systems.
For engineers reviewing the S29GL032N90FFIS42 datasheet, S29GL032N90FFIS42 pinout, S29GL032N90FFIS42 application, or S29GL032N90FFIS42 equivalent, key selection criteria include uniform-sector erase flexibility, Secured Silicon Sector with factory-programmed 128-word ESN, CFI compliance for host auto-configuration, and hardware-accelerated programming via WP#/ACC input.
Technical Context
This device implements a NOR Flash architecture with hot-electron injection programming and hot-hole assisted sector erase. It uses an 110 nm MirrorBit process and features VersatileI/O™ control where all I/O voltage levels are referenced to VIO (1.65–3.6 V), independent of VCC.
It supports full command-set compatibility with JEDEC JESD21-C, including Autoselect, CFI query, Program Suspend/Resume, and Erase Suspend/Resume. Sector protection includes Persistent Sector Protection (PPB lock bit) and Password Sector Protection requiring 16-byte authentication before write/erase access.
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 microcontroller-based systems. |
| Page Read Time | 25 ns; supports high-throughput sequential instruction fetch from 8-word buffer. |
| Erase Endurance | 100,000 cycles per sector; ensures long-term field reliability for field-upgradable firmware. |
| Data Retention | 20 years typical; guarantees data integrity over product lifecycle without refresh. |
| Supply Voltage | VCC = 2.7–3.6 V, VIO = 1.65–3.6 V; allows flexible I/O interfacing with 1.8 V or 3.3 V controllers. |
| Standby Current | 1 µA typical; minimizes power draw in always-on embedded systems during idle states. |
Pinout & Package
Package: 48-pin TSOP (Type 1, standard thin small outline package, 12 × 20 mm body). Pinout validated per Infineon document 001-98525 Rev. *B, Figure 1 (S29GL032N Models 03/04).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A21 | Address inputs | 22-bit address bus supporting full 32 Mbit addressing; A-1 (DQ15/A-1) serves dual function as MSB address or data bit. |
| DQ0–DQ15 | Data I/O bus | 16-bit bidirectional data path; DQ15 doubles as A-1 for extended addressing in word mode. |
| CE# | Chip enable | Active-low chip select; enables device for read/write operations only when asserted. |
| OE# | Output enable | Active-low control for output buffer; decouples data bus during address setup or standby. |
| WE# | Write enable | Active-low strobe for latching commands, addresses, and data during programming/erase sequences. |
| WP#/ACC | Write protect / accelerate | Low = hardware sector protection (first/last sector); high + VHH = accelerated programming for production throughput. |
| RY/BY# | Ready/Busy indicator | Open-drain active-low output signaling completion of internal program/erase cycles. |
| RESET# | Hardware reset | Active-low asynchronous reset terminating any ongoing operation and returning device to read mode. |
| BYTE# | Bus width select | High = 16-bit mode; low = 8-bit mode (DQ0–DQ7 only active); enables compatibility with narrow-data hosts. |
| VIO | I/O voltage reference | Defines logic thresholds for all address, control, and data pins; enables mixed-voltage system interfacing. |
Key Features
| Feature | Design Value |
|---|---|
| Secured Silicon Sector | 128-word (256-byte) factory-locked region with 8-word ESN; provides immutable device identity for secure boot and anti-cloning. |
| CFI Compliance | JEDEC-standard Common Flash Interface; enables automatic detection and configuration by host BIOS/firmware without hard-coded parameters. |
| Program Suspend/Resume | Allows interrupting active programming to read other sectors; critical for real-time OS environments requiring concurrent code/data access. |
| Advanced Sector Protection | Persistent (PPB lock bit) and Password modes; prevents unauthorized firmware modification while allowing selective reprogramming in field-deployed units. |
| Unlock Bypass Mode | Reduces multi-word programming overhead from 4 to 2 write cycles per word; improves flash update speed in manufacturing and OTA workflows. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NOR Flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S29GL032N90TFIR20 | Same die, 48-ball fine-pitch BGA (VBK048) package; no TSOP pins; 110 ns access at VIO = 1.65–3.6 V. | Used in space-constrained PCBs where board area is prioritized over manual reworkability. | Select when footprint density > thermal dissipation; requires BGA reflow capability and X-ray inspection. |
| MX29GL320EHTI-90G | Micron 32 Mbit NOR Flash; 90 ns access; JEDEC-compatible but lacks Secured Silicon Sector and Password Protection. | Lower-security industrial gateways where firmware authenticity is managed externally. | Choose for cost-sensitive designs without cryptographic binding needs; verify CFI descriptor compatibility. |
Compared with S29GL032N90FFIS42, the BGA variant trades serviceability for miniaturization, while the Micron alternative reduces security features to lower BOM cost-neither offers identical secured identity or persistent protection capabilities.

FAQ
What is the function of the BYTE# pin on S29GL032N90FFIS42?
The BYTE# pin selects data bus width: when high, the device operates in full 16-bit mode (DQ0–DQ15 active); when low, it operates in 8-bit mode (DQ0–DQ7 only), enabling compatibility with microcontrollers or SoCs that lack a full 16-bit external bus. This pin does not affect address or control signals.
Does S29GL032N90FFIS42 support both uniform and boot sector architectures?
No - S29GL032N90FFIS42 is a uniform sector model with sixty-four 32 Kword (64 KB) sectors. Boot sector variants (e.g., S29GL032NxxxB) include eight 4 Kword boot sectors plus sixty-three main sectors; this part number's suffix "S42" and ordering guide confirm uniform configuration.
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 (ESN) at the factory. Access requires a specific unlock command sequence (0xAA, 0x55, 0x80, 0xAA, 0x55, 0x10); once locked, no further writes or erases are possible, ensuring permanent device identification.
Can S29GL032N90FFIS42 be used with a 1.8 V I/O controller?
Yes - by setting VIO = 1.65–1.95 V, all input thresholds and output drive levels conform to 1.8 V logic standards, while VCC remains at 3.0 V (2.7–3.6 V) for core Flash operation. This dual-voltage capability is enabled by VersatileI/O™ and verified in AC characteristics Table 15 of datasheet 001-98525 Rev. *B.
