Product details
Overview
S29GL032N90TFI033 from Infineon Technologies (formerly Cypress) is a 32 Mbit (4,194,304-byte), 16-bit-wide single-supply MirrorBit Flash memory IC with 90 ns access time, uniform sector architecture (64 × 64 KB sectors), and Secured Silicon Sector for factory- or customer-programmed 256-byte electronic serial number. It operates from 2.7–3.6 V VCC and 1.65–3.6 V VIO, and is used in embedded boot code storage for industrial controllers requiring deterministic read timing and hardware write protection.
For engineers reviewing the S29GL032N90TFI033 datasheet, S29GL032N90TFI033 pinout, S29GL032N90TFI033 application, or S29GL032N90TFI033 equivalent, key selection criteria include JEDEC-compliant command set, 100,000 erase cycles per sector, CFI compliance for host auto-detection, and dual-voltage I/O control via VIO pin - all critical for legacy system upgrades and long-lifecycle industrial firmware storage.
Technical Context
This device implements a synchronous command-register-based interface with hardware reset (RESET#), ready/busy status (RY/BY#), and programmable sector protection. Its 110 nm MirrorBit process enables hot-hole erase and hot-electron programming, supporting both page read (8-word buffer, 25 ns) and buffered write (16-word buffer) operations.
The architecture separates chip enable (CE#), output enable (OE#), and write enable (WE#) controls, enabling concurrent read/program/erase suspend-resume functionality. VIO pin sets all I/O voltage thresholds independently of VCC, allowing interoperability with 1.8 V or 3.3 V logic domains while maintaining full 3.0 V core operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 32 Mbit (4,194,304 bytes), organized as 2,097,152 × 16-bit words |
| Access Time | 90 ns at VCC = 2.7–3.6 V and VIO = 2.7–3.6 V - ensures deterministic boot latency in real-time systems |
| Sector Architecture | 64 uniform 64 KB sectors - simplifies firmware partitioning and OTA update management |
| Erase Endurance | 100,000 cycles per sector - supports field firmware updates over 10+ years in deployed equipment |
| Data Retention | 20 years at 125°C - validated for automotive under-hood and industrial high-temp environments |
| I/O Voltage Range | VIO = 1.65–3.6 V - enables direct interfacing with 1.8 V microcontrollers without level shifters |
| Power Consumption | 1 µA standby current - essential for battery-backed or energy-harvested edge nodes |
Pinout & Package
Package: 48-pin TSOP (Type I, standard thin small outline package), body size 12 mm × 20 mm, lead pitch 0.5 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A20 | Address inputs | 21-bit address bus supporting full 32 Mbit addressing; A-1 used for DQ15/A-1 multiplexing in x16 mode |
| DQ0–DQ15 | Data I/O bidirectional bus | 16-bit data path; DQ15 doubles as A-1 for x16 configuration; supports BYTE#-controlled x8/x16 mode |
| CE#, OE#, WE# | Chip, output, and write enable controls | Independent gating enables precise timing control for burst reads and non-blocking writes |
| WP#/ACC | Write protect / accelerated program input | Low-active WP# protects first/last sector; high-voltage ACC mode reduces programming time during production |
| RY/BY# | Ready/Busy output | Open-drain active-low signal indicating ongoing program/erase - eliminates need for polling in interrupt-driven systems |
| RESET# | Hardware reset input | Asynchronous reset terminates all operations and restores device to known state - critical for safe boot recovery |
| VIO | I/O supply reference | Sets input threshold and output drive levels independently of VCC - enables mixed-voltage system integration |
Key Features
| Feature | Design Value |
|---|---|
| Secured Silicon Sector | 256-byte factory- or user-lockable region with 16-byte electronic serial number - enables secure device identity binding in IoT gateways |
| Program/Erase Suspend-Resume | Allows reading other sectors during active program/erase - enables real-time logging while updating firmware partitions |
| CFI Compliance | Standardized query table allows host BIOS or bootloader to auto-identify device geometry and command set - eliminates hard-coded flash drivers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S29GL032N90TFI020 | Same die, 48-pin TSOP but with 020 speed grade (110 ns access at VIO = 1.65–3.6 V) | Lower performance margin; suitable only where 90 ns timing is not required | Select when cost sensitivity outweighs boot-time latency constraints |
| MX29GL32EHXFI-90G | Micron 32 Mbit Flash with identical 48-pin TSOP-48 pinout and 90 ns access, but no Secured Silicon Sector or VIO pin | Lacks electronic serial number and mixed-voltage I/O support - requires external level shifting for 1.8 V hosts | Choose only if Secured Silicon and VIO flexibility are not needed and Micron supply chain alignment is preferred |
Compared with S29GL032N90TFI033, the 020 variant trades access speed for cost in non-latency-critical applications, while the MX29GL32EHXFI-90G sacrifices security and voltage flexibility for broader distributor availability - making the 033 optimal for new designs requiring secure, mixed-voltage boot storage.

FAQ
Is S29GL032N90TFI033 pin-compatible with older S29GL032N variants?
Yes - the "033" suffix denotes the 90 ns speed grade in 48-pin TSOP packaging with VIO support, and maintains identical pinout and command set with prior S29GL032N revisions. All control, address, and data pins match the JEDEC-standard 48-pin TSOP footprint defined in the original Cypress datasheet 001-98525 Rev. *B.
Does this device require external high-voltage circuitry for programming?
No - S29GL032N90TFI033 uses single 3.0 V supply for all operations. The WP#/ACC pin accepts elevated voltage (typically 5.5 V) only to activate accelerated programming mode during manufacturing; standard 3.0 V programming is fully functional and does not require external HV generation.
Can the Secured Silicon Sector be reprogrammed after factory locking?
No - once the Secured Silicon Sector is permanently locked (via command sequence), it becomes read-only and cannot be erased or rewritten. The 16-byte electronic serial number is programmed at factory or by the customer before final lock, and remains immutable thereafter.
What is the role of the VIO pin in system design?
VIO sets input voltage thresholds and output drive strength for all address, control, and data pins independently of VCC. When interfaced with a 1.8 V microcontroller, VIO = 1.8 V ensures correct logic recognition and clean signal edges - eliminating level shifters while maintaining full 3.0 V core operation for reliable flash endurance.
