Product details
Overview
S29GL032N90DFI020 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-programmed 128-word 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-based sector protection.
For engineers reviewing the S29GL032N90DFI020 datasheet, S29GL032N90DFI020 pinout, S29GL032N90DFI020 application, or S29GL032N90DFI020 equivalent, key selection criteria include JEDEC-compliant command set compatibility, 100,000 erase cycles per sector, CFI interface support, hardware reset (RESET#) and ready/busy (RY/BY#) signaling, and dual-voltage I/O control via VIO.
Technical Context
This device implements a NOR Flash architecture with hot-electron injection programming and hot-hole assisted erase, enabling byte/word-level random access and sector-level erasure without disturbing adjacent sectors. Its command register-based control logic accepts standard microprocessor write cycles to initiate read, program, or erase operations, with status reported via DQ7 polling, DQ6 toggle bits, or RY/BY# output.
The Advanced Sector Protection system supports both Persistent Sector Protection (lock-bit controlled) and Password Sector Protection (16-byte password required), while the Secured Silicon Sector provides a permanently locked 256-byte region accessible only through dedicated unlock sequences. The WP#/ACC pin enables accelerated programming when driven high and protects first/last sector regardless of software protection state.
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 |

Pinout & Package
Package: 48-pin TSOP (Standard Thin Small Outline Package), 12 × 20 mm body, JEDEC MO-142AC compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| CE#, OE#, WE# | Chip, output, write enable | Independent active-low controls allow interleaved read/write operations and partial array access |
| RESET# | Hardware reset | Asynchronous active-low input that terminates ongoing erase/program and restores device to read mode |
| RY/BY# | Ready/Busy indicator | Open-drain output signals active programming/erase; used for hardware flow control without polling |
| WP#/ACC | Write protect / accelerate | Low = sector protection; high = accelerated programming via internal charge pump - critical for production line throughput |
| VIO | I/O voltage reference | Sets input threshold and output drive strength independently of VCC - enables mixed-voltage system interfacing |
Key Features
| Feature | Design Value |
|---|---|
| Secured Silicon Sector | 256-byte factory-locked region with 16-byte electronic serial number - enables secure device authentication and anti-cloning |

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-ball fine-pitch BGA (VBK048) package instead of 48-pin TSOP; identical timing and command set | Required for space-constrained PCB layouts where TSOP footprint is prohibitive | Select when board area is constrained and reflow-compatible BGA assembly is available |
| MX29GL32EHXFI-90G | 32 Mbit NOR Flash with 90 ns access, but uses Macronix's MX29GL architecture; no Secured Silicon Sector or Password Protection | Lacks factory-programmed serial number and password-based sector lock - unsuitable for secure boot or anti-counterfeiting | Choose only for cost-sensitive, non-security-critical applications where CFI compatibility suffices |
Compared with S29GL032N90TFI020, the TSOP variant offers easier prototyping and socket-based testing; versus MX29GL32EHXFI-90G, it delivers certified security features essential for regulated medical and automotive use - not just raw capacity equivalence.

FAQ
What is the function of the VIO pin on S29GL032N90DFI020?
The VIO pin sets the input voltage thresholds and output drive strength for all address, control, and data pins independently of VCC. With VIO ranging from 1.65 V to 3.6 V, it enables direct interfacing to 1.8 V or 3.3 V host processors without level shifters, maintaining signal integrity across mixed-voltage designs.
Does S29GL032N90DFI020 support byte-wide data access?
Yes - when the BYTE# pin is asserted low, the device operates in 8-bit mode using DQ0–DQ7 only, with DQ15 functioning as A-1. This allows compatibility with 8-bit microcontrollers and reduces bus routing complexity on cost-sensitive designs without sacrificing memory density.
How is the Secured Silicon Sector protected from unauthorized access?
Access requires a two-step unlock sequence: first writing 0xAA to address 0x555, then 0x55 to address 0x2AA. Once unlocked, the 256-byte sector can be read; however, factory-programmed content cannot be modified, and the sector remains permanently locked after initial configuration - preventing tampering even with physical debugger access.
Can S29GL032N90DFI020 be used in place of older S29GL032P models?
No - the S29GL032N uses MirrorBit technology on 110 nm process with different command timing and VIO dependency, whereas S29GL032P is based on older floating-gate architecture. Pinout is compatible, but software must be updated to support new status bit behavior (DQ6/DQ2 toggle), CFI query structure, and unlock bypass commands.
