Infineon Technologies S29GL032N90FFIS13

Overview

S29GL032N90FFIS13 from Infineon Technologies (formerly Cypress) is a 32-Mbit, 16-bit wide single-power-supply MirrorBit Flash memory IC with 90 ns access time, organized as 2,097,152 words (4,194,304 bytes), factory-erased and supporting uniform sector architecture (64 × 64 KB sectors). It operates from a single 3.0 V supply (2.7–3.6 V), features Secured Silicon Sector with 128-word ESN, and is used in embedded boot code storage for industrial controllers and network edge devices.

For engineers reviewing the S29GL032N90FFIS13 datasheet, S29GL032N90FFIS13 pinout, S29GL032N90FFIS13 application, or S29GL032N90FFIS13 equivalent, key selection criteria include JEDEC-compliant command set, 100,000 erase cycles per sector, CFI compliance for host auto-configuration, and hardware write protection via WP#/ACC and RESET# pins.

Technical Context

This device implements a NOR Flash architecture with hot-electron injection programming and hot-hole assisted erase, enabling byte/word-level random read and sector-level erase. Its VersatileI/O™ control uses VIO (1.65–3.6 V) to independently set input/output voltage levels, decoupling interface logic from core VCC.

The command-based operation supports Program Suspend/Resume and Erase Suspend/Resume, allowing concurrent read access during active programming or erasure of other sectors. Status reporting is implemented via DQ7 Data# Polling, DQ6/DQ2 toggle bits, and RY/BY# output - all fully compliant with JEDEC Standard JESD21-C.

FAQ

What is the function of the WP#/ACC pin on S29GL032N90FFIS13?

The WP#/ACC pin serves dual roles: when pulled low, it hardware-protects the first or last sector against accidental erase or program; when driven high with an elevated voltage (VHH ≈ 11.5 V), it accelerates internal programming timing for faster production throughput. This dual functionality eliminates need for external voltage switching circuitry in manufacturing test fixtures.

Does S29GL032N90FFIS13 support 8-bit data bus operation?

Yes - when the BYTE# pin is asserted high, the device operates in 8-bit mode using only DQ0–DQ7; DQ8–DQ15 become high-impedance. This mode maintains full command compatibility and preserves all protection and suspend features, enabling reuse of 8-bit microcontroller interfaces without redesign.

How is the Secured Silicon Sector programmed and locked?

The Secured Silicon Sector is pre-programmed at the factory with a unique 8-word (16-byte) Electronic Serial Number and can be permanently locked via command sequence (0x60 → 0xD0). Once locked, no further writes or erases are possible in that 256-byte region - even with VPP applied - ensuring immutable device identity for anti-counterfeiting and traceability.

Can S29GL032N90FFIS13 be used in systems with mixed 1.8 V and 3.3 V logic?

Yes - by setting VIO = 1.8 V and VCC = 3.3 V, the device accepts 1.8 V logic levels on all address, control, and data pins while maintaining full 3.3 V core operation. This eliminates external level shifters in heterogeneous SoC designs, reducing BOM count and signal integrity risk.
