Product details
Overview
S29GL032N90FFI042 from Infineon Technologies (formerly Cypress) is a 32-Mbit, 16-bit-wide single-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 100,000 erase cycles per sector. 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 S29GL032N90FFI042 datasheet, S29GL032N90FFI042 pinout, S29GL032N90FFI042 application, or S29GL032N90FFI042 equivalent, key selection criteria include uniform 64 KB sector architecture, Secured Silicon Sector with factory-programmed 16-byte ESN, VIO-referenced VersatileI/O™, CFI compliance, and hardware reset (RESET#) with RY/BY# status signaling.
Technical Context
This device implements a NOR Flash architecture with hot-electron injection programming and hot-hole assisted erase. Its command-set compatibility with JEDEC JESD21-C ensures interoperability with legacy host controllers, while the 110 nm MirrorBit process enables high density and reliability without charge-trap degradation mechanisms.
The flexible sector layout-64 uniform 32 Kword (64 KB) sectors-supports independent erase/program operations per sector. The Secured Silicon Sector (128-word/256-byte) is permanently locked via command sequence and provides tamper-resistant storage for serial numbers or cryptographic keys.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 32 Mbit (2,097,152 × 16-bit words); enables full boot image storage for mid-tier microcontrollers. |
| Access Time | 90 ns at VCC = 2.7–3.6 V; meets real-time boot latency requirements in industrial PLCs. |
| Page Read Time | 25 ns; supports burst reads of up to 8 words from internal buffer, reducing instruction fetch overhead. |
| Erase Endurance | 100,000 cycles per sector; qualifies for field-updatable firmware in devices with 5+ year service life. |
| Data Retention | 20 years at +85°C; validated for use in extended-temperature industrial environments. |
| VIO Range | 1.65–3.6 V; allows I/O voltage scaling to match host processor logic levels independently of VCC. |
| Standby Current | 1 µA typical; enables low-power sleep modes in battery-backed embedded systems. |
Pinout & Package
Package: 48-pin TSOP (Type I, standard thin small outline package), 12 × 20 mm body, lead pitch 0.5 mm. Pin-compatible with JEDEC MO-142AC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A21 | Address Inputs | 22-bit address bus supporting full 32 Mbit addressing; A-1 (DQ15/A-1) multiplexed for byte/word mode selection. |
| DQ0–DQ15 | Data/Address Bus | 16-bit bidirectional data bus; DQ15 doubles as A-1 for byte-mode configuration when BYTE# = LOW. |
| CE#, OE#, WE# | Chip/Output/Write Enable | Independent control lines enable concurrent access arbitration and eliminate bus contention during read/write. |
| RESET# | Hardware Reset Input | Asynchronous active-low signal that terminates ongoing erase/program and restores device to read mode. |
| RY/BY# | Ready/Busy Output | Open-drain status flag indicating active programming/erase; eliminates need for polling DQ7/DQ6 in time-critical systems. |
| WP#/ACC | Write Protect / Accelerated Program | Logic-low on WP# protects first/last sector; high-voltage ACC mode reduces program time by ~30% in production test. |
Key Features
| Feature | Design Value |
|---|---|
| Secured Silicon Sector | 256-byte factory-lockable region with 16-byte ESN; prevents cloning or unauthorized firmware extraction. |
| Password Sector Protection | Three-tier password mechanism requiring valid 16-byte key before unlocking protected sectors for reprogramming. |
| Program/Erase Suspend | Allows host to interrupt active programming/erasing to service higher-priority reads from other sectors. |
| CFI Compliance | Standardized parameter tables accessible via command sequence; enables automatic flash driver detection in U-Boot/Linux BSPs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NOR Flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S29GL032N90TFI020 | Same die, 48-ball fine-pitch BGA (VBK048) package; no TSOP pins; 1.65–3.6 V VIO range identical. | Used where board space constraints require BGA mounting and automated optical inspection is available. | Select when PCB layout favors compact BGA footprint and thermal profile permits reflow-compatible handling. |
| MX29GL320EHTI-90G | 32 Mbit, 90 ns, but uses 1.8 V core + 3.3 V I/O; lacks Secured Silicon Sector and Password Protection features. | Applicable in cost-sensitive consumer electronics where security features are not required. | Choose only if security and long-term data integrity are secondary to BOM cost reduction. |
Compared with S29GL032N90FFI042, the TSOP-packaged alternative offers identical functionality in a through-hole compatible form factor, while the Macronix part trades security and endurance for lower voltage operation and reduced feature set-making it unsuitable for certified industrial or medical deployments.

FAQ
What is the function of the WP#/ACC pin on S29GL032N90FFI042?
The WP#/ACC pin serves dual functions: when held LOW, it hardware-protects the first or last sector against accidental writes or erases; when driven to VCC + 0.5 V (typically 3.6–4.2 V), it activates accelerated programming mode, reducing single-word program time by approximately 30%. This dual-role pin is electrically isolated from VCC and requires external voltage boosting circuitry for ACC operation.
Does S29GL032N90FFI042 support byte-wide data access?
Yes, S29GL032N90FFI042 supports both 16-bit and 8-bit data bus configurations. When BYTE# is asserted LOW, the device operates in 8-bit mode using DQ0–DQ7 as the data bus, with DQ15 functioning as A-1 to select upper/lower byte addressing. This mode maintains full command-set compatibility and preserves all protection and suspend features.
How is the Secured Silicon Sector programmed and locked?
The Secured Silicon Sector (128 words / 256 bytes) is programmed using standard unlock-bypass command sequences, then permanently locked via the Persistent Protection Bit (PPB). Once PPB is set, no further writes or erases are possible-even with valid passwords or ACC voltage. Factory programming of the 16-byte Electronic Serial Number occurs during wafer sort and is verified before shipment.
Can S29GL032N90FFI042 be used in place of older S29GL032P models?
No-S29GL032N90FFI042 is not a drop-in replacement for S29GL032P. The 'N' suffix denotes MirrorBit technology with enhanced sector protection, CFI compliance, and VIO-referenced I/O, whereas 'P' models use older floating-gate architecture, lack Secured Silicon Sector, and have different AC timing and command set behavior. Migration requires firmware driver updates and validation of RESET# and RY/BY# timing margins.
