Product details
Overview
S29GL032N90TFA020 from Infineon Technologies (formerly Cypress) is a 32-Mbit, 16-bit-wide single-power-supply MirrorBit Flash memory IC with 90 ns access time, 64 KB uniform sector architecture, and Secured Silicon Sector for factory-programmed 16-byte 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 S29GL032N90TFA020 datasheet, S29GL032N90TFA020 pinout, S29GL032N90TFA020 application, or S29GL032N90TFA020 equivalent, key selection criteria include uniform 64 KB sector count (64 sectors), VIO-supported VersatileI/O™ (1.65–3.6 V), 100,000 erase cycles per sector, 20-year data retention, and hardware write protection via WP#/ACC pin.
Technical Context
This device implements a NOR Flash architecture with hot-electron programming and hot-hole assisted erase, enabling byte/word-level random read and sector-level erase. Its command register interface accepts standard microprocessor write timing sequences to initiate program, erase, suspend/resume, and protection operations without external high-voltage generators.
The Secured Silicon Sector provides a dedicated 256-byte region with factory- or customer-lockable content, while Advanced Sector Protection includes both Persistent Sector Protection (non-volatile lock bits) and Password Sector Protection requiring valid 8-word password entry before modification of protected sectors.
Key Specifications

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 industrial temperature grade (–40°C to +85°C) vs. commercial (0°C to +70°C) | Required for extended-temperature deployments where ambient exceeds 70°C | Select when operating environment exceeds commercial temperature range; identical pinout and command set |
| MX29GL320EBTI-90G | 32 Mbit, 90 ns, 48-pin TSOP but Macronix device with different CFI query structure and no Secured Silicon Sector | Lacks factory-programmed serial number and persistent password protection | Choose only if Secured Silicon and Advanced Sector Protection features are not required; verify CFI descriptor compatibility in host bootloader |
Compared with S29GL032N90TFA020, the S29GL032N90TFI020 extends thermal reliability without functional change, while MX29GL320EBTI-90G sacrifices security features for cost-sensitive applications where device identity and sector locking are unnecessary.

FAQ
What is the function of the WP#/ACC pin on S29GL032N90TFA020?
The WP#/ACC pin serves dual roles: when held low, it hardware-protects the first or last sector regardless of software protection settings; when driven to 5.5 V (±0.5 V), it enables accelerated programming for higher throughput in manufacturing. This dual functionality is confirmed in the datasheet's Section 8.16 and requires no external circuitry beyond a voltage translator for ACC mode.
Does S29GL032N90TFA020 support 8-bit data bus operation?
No, S29GL032N90TFA020 is a 16-bit-only device. Unlike some variants in the S29GL032N family (e.g., models with BYTE# pin), this specific part number lacks the BYTE# input and does not support 8-bit data bus configuration. The datasheet explicitly states "16-bit wide data bus only" for this ordering option.
How is the Secured Silicon Sector programmed and locked?
The Secured Silicon Sector is pre-programmed with a unique 16-byte electronic serial number at the factory and can be permanently locked using the Secured Silicon Sector Lock command (0x20). Once locked, no further writes or erases are possible in that 256-byte region. The lock operation is irreversible and verified by reading status register bit SR[7].
Can S29GL032N90TFA020 be used with a 1.8 V I/O interface?
Yes, provided VIO is supplied at 1.8 V (within 1.65–3.6 V range) and all control/data signals meet VIH/VIL thresholds defined for that VIO level. The device's VersatileI/O™ architecture decouples I/O voltage from VCC (3.0 V), enabling direct interfacing with 1.8 V FPGAs or ASICs without level shifters, as confirmed in Section 3.2 of the datasheet.
