Product details
Overview
S29GL032N90FFI013 from Infineon Technologies (formerly Cypress) is a 32 Mbit (4,194,304-byte), 16-bit-wide single-supply MirrorBit Flash memory with 90 ns access time, uniform sector architecture (64 × 64 KB sectors), and Secured Silicon Sector for factory-programmed 16-byte electronic serial number. It operates from 2.7–3.6 V VCC and 1.65–3.6 V VIO, and is used in industrial control firmware storage where deterministic boot code integrity and long-term data retention are required.
For engineers reviewing the S29GL032N90FFI013 datasheet, S29GL032N90FFI013 pinout, S29GL032N90FFI013 application, or S29GL032N90FFI013 equivalent, key selection criteria include JEDEC-compliant command set compatibility, hardware reset (RESET#) and ready/busy (RY/BY#) signaling, 100,000 erase cycles per sector, and support for program/erase suspend-resume operations in embedded boot memory systems.
Technical Context
This device implements a 110 nm MirrorBit floating-gate NOR architecture with hot-hole assisted erase and hot-electron injection programming. It features separate CE#, WE#, and OE# controls, supports both word- and byte-access modes via BYTE# input, and uses VIO-referenced I/O voltage scaling for flexible interfacing with 1.65–3.6 V logic domains.
The flash integrates CFI (Common Flash Interface) for automatic device identification, Advanced Sector Protection with persistent and password-based locking, and hardware-level write protection via WP#/ACC. Erase and program status is reported through DQ7 polling, DQ6/DQ2 toggle bits, and RY/BY# output-enabling concurrent host read operations during background flash operations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 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 - enables direct CPU bus interface without wait states in 33 MHz bus systems |
| Erase Endurance | 100,000 cycles per sector - supports field firmware updates over 10+ years in industrial logging applications |
| Data Retention | 20 years typical - ensures boot code integrity across product lifecycle without refresh |
| Supply Voltage | VCC = 2.7–3.6 V; VIO = 1.65–3.6 V - allows interoperability with mixed-voltage SoC interfaces (e.g., 1.8 V I/O, 3.3 V core) |
| Page Read Buffer | 8-word (16-byte) buffer with 25 ns page access - reduces sequential read latency by >60% vs. random access |
| Write Buffer | 16-word (32-byte) buffer - cuts multi-word programming time by minimizing command overhead per write burst |
Pinout & Package
Package: 48-pin TSOP (Type I, standard thin small outline package, 12 × 20 mm body, 0.5 mm pitch). Pinout validated per Cypress/Infineon Document 001-98525 Rev. *B, Figure 1 (S29GL032N Models 03/04).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A20 | Address inputs | 21-bit address bus supporting full 32 Mbit addressing; A-1 used as DQ15 in x16 mode |
| DQ0–DQ15 | Data I/O bidirectional bus | 16-bit parallel interface; DQ15 doubles as A-1 for x8/x16 configuration detection |
| CE# | Chip enable (active low) | Primary device select; must be asserted before WE# or OE# to initiate valid cycle |
| WE# | Write enable (active low) | Controls write latching; combined with CE# and OE# to define read/write/standby states |
| OE# | Output enable (active low) | Enables data output drivers only; does not affect internal state or timing of writes/erases |
| RESET# | Hardware reset (active low) | Aborts all operations and returns device to read array state; tied to system reset for safe boot recovery |
| RY/BY# | Ready/Busy output (active low) | Open-drain signal indicating active program/erase; used for hardware handshaking instead of polling |
| WP#/ACC | Write protect / accelerate input | Low = protects first/last sector; high + VHH = enables accelerated programming for production throughput |
| BYTE# | Bus width select | Low = x16 mode; high = x8 mode (DQ0–DQ7 only active); enables shared PCB layout across density variants |
| VIO | I/O supply reference | Sets input threshold and output drive level independently from VCC - critical for mixed-voltage designs |
Key Features
| Feature | Design Value |
|---|---|
| Secured Silicon Sector | 128-word (256-byte) factory-locked region with 8-word (16-byte) electronic serial number - provides immutable device identity for secure boot and traceability |
| Program/Erase Suspend-Resume | Allows host to interrupt ongoing program/erase in one sector to read/program another - enables real-time firmware patching without halting system operation |
| CFI Compliance | Standardized query table at address 0x55 × 0x55 enables automatic detection and configuration by bootloader or OS flash driver - eliminates hard-coded timing assumptions |
| Unlock Bypass Mode | Reduces multi-word programming from 4-cycle to 2-cycle command sequence - cuts firmware update time by ~40% in high-volume manufacturing |
| Hardware Data Protection | On-chip VCC detector disables writes during brown-out or power ramp-up - prevents corruption during unstable supply conditions |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NOR flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S29GL032N90TFI010 | Same die, 48-ball fine-pitch BGA (VBK048) package instead of 48-pin TSOP; identical timing, voltage, and command set | Used where board space is constrained and automated BGA reflow is available; no change to firmware or timing design | Select for compact, high-density layouts; requires PCB redesign but retains full software compatibility |
| MX29GL32EHXFI-90G | Micron 32 Mbit NOR flash; 90 ns access, 1.8/3.3 V dual I/O supply; JEDEC-compatible but lacks Secured Silicon Sector and CFI query table | Suitable for cost-sensitive consumer applications where electronic serial number and auto-detection are not required | Choose when Secured Silicon and CFI are unnecessary and BOM cost reduction is prioritized over long-term traceability |
Compared with S29GL032N90FFI013, the TSOP-packaged alternative maintains identical electrical behavior and firmware compatibility, while the Micron part trades security and configurability for lower unit cost and simplified qualification-making it viable only where device identity and bootloader flexibility are noncritical.

FAQ
Does S29GL032N90FFI013 support both x8 and x16 data bus widths?
Yes. The BYTE# input selects bus width: logic low enables full 16-bit operation (DQ0–DQ15 active), while logic high configures x8 mode (DQ0–DQ7 only). In x8 mode, A-1 is not used, and DQ15 functions solely as data. This dual-mode capability allows shared PCB footprint across different host processor interfaces without redesign.
What is the function of the WP#/ACC pin, and how does it differ from standard write protection?
WP#/ACC serves two roles: when pulled low, it permanently protects the first or last sector regardless of software protection settings; when driven high with elevated voltage (VHH ≈ 11.5 V), it accelerates programming for faster factory throughput. Unlike passive WP pins, this dual-function pin provides both fail-safe hardware protection and production optimization in a single terminal.
Can the Secured Silicon Sector be reprogrammed after factory locking?
No. Once locked-either at factory or by customer command-the 128-word Secured Silicon Sector becomes permanently read-only. The 16-byte electronic serial number is written during final test and cannot be altered, erased, or overwritten. This immutability is enforced by on-die fuse logic and is independent of software sector protection mechanisms.
How does the Ready/Busy# (RY/BY#) signal interact with DQ7 polling during erase operations?
RY/BY# and DQ7 polling are functionally redundant but electrically distinct status methods: RY/BY# is an open-drain hardware signal that goes high when idle and low during active program/erase; DQ7 toggles during operation and stabilizes when complete. Using RY/BY# avoids bus contention and eliminates need for continuous DQ7 reads, improving system efficiency in interrupt-driven architectures.
