Product details
Overview
S29GL032N90FFI033 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 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 and network edge devices.
For engineers reviewing the S29GL032N90FFI033 datasheet, S29GL032N90FFI033 pinout, S29GL032N90FFI033 application, or S29GL032N90FFI033 equivalent, key selection criteria include JEDEC-compliant command set, hardware reset (RESET#) and ready/busy (RY/BY#) signaling, 100,000 erase cycles per sector, CFI compliance for host auto-configuration, and WP#/ACC-enabled accelerated programming in production environments.
Technical Context
This device implements a synchronous command-set interface compatible with JEDEC JESD21C, supporting sector erase, chip erase, and page programming via write sequences latched internally. Its 110 nm MirrorBit process enables hot-hole erase and hot-electron program mechanisms, delivering 20-year data retention and 1 µA standby current.
The architecture includes dedicated control logic for Program Suspend/Resume and Erase Suspend/Resume, allowing concurrent read operations during active programming or erasure of other sectors. The Secured Silicon Sector (128-word/256-byte) is permanently locked at factory or by user command and accessible only via defined unlock sequences.
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 max at VCC = 2.7–3.6 V - ensures compatibility with 11 MHz bus timing in legacy microcontroller boot interfaces |
| Erase Endurance | 100,000 cycles per sector - supports field firmware updates over 10+ years in industrial gateways |
| Data Retention | 20 years typical at 125°C - validated for automotive under-hood and telecom base station applications |
| Supply Voltage | VCC = 2.7–3.6 V; VIO = 1.65–3.6 V - enables direct interfacing with 1.8 V or 3.3 V I/O domains without level shifters |
| Page Read Buffer | 8-word (16-byte) buffer - reduces sequential read latency in boot loader execution paths |
| Write Buffer | 16-word (32-byte) buffer - cuts multi-word programming time by >40% vs. byte-by-byte writes |
Pinout & Package
Package: 48-pin TSOP (Type I, standard thin small outline package), 12 × 20 mm body, lead pitch 0.5 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A21 | Address inputs | 22-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#, OE#, WE# | Chip, output, and write enable controls | Independent gating enables interleaved access and low-power partial activation |
| RESET# | Hardware reset input | Asynchronous active-low signal that terminates ongoing erase/program and restores read mode |
| RY/BY# | Ready/Busy output | Open-drain status flag indicating internal operation completion; used for polling-free interrupt-driven firmware |
| WP#/ACC | Write protect / accelerate programming input | Low = sector protection; high + VHH = accelerated programming (factory throughput mode) |
| BYTE# | Bus width select | High = x16 mode; low = x8 mode with DQ0–DQ7 only active |
| VIO | I/O voltage reference | Determines all input thresholds and output drive levels - decouples core logic voltage from interface voltage |
Key Features
| Feature | Design Value |
|---|---|
| Secured Silicon Sector | 128-word (256-byte) factory-lockable region with 8-word ESN - enables secure device identity binding for firmware authentication |
| CFI Compliance | JEDEC-standard Common Flash Interface - allows runtime detection of geometry, timing, and protection features by bootloader without hard-coded assumptions |
| Program Suspend/Resume | Pause active programming to read any other sector - critical for real-time OS where boot code must remain readable during firmware update |
| Advanced Sector Protection | Persistent and Password-based modes - prevents accidental or malicious overwrite of boot sectors without explicit unlock sequence or valid password |
| Unlock Bypass Mode | Two-cycle instead of four-cycle command sequence - reduces overhead in high-volume system programming by ~50% per word |
Applications
| Industrial PLC Firmware Storage | Telecom Edge Router Boot Memory |
|---|---|
Use Scenario: Storing boot loader and FPGA configuration bitstreams in programmable logic controllers operating in -40°C to +85°C environments.

IC Role / Device Role / Timing Role: Low-power non-volatile storage accessed during cold start; standby current <1 µA extends battery life. Use Value: 1.65–3.6 V VIO range allows direct connection to 1.8 V MCU I/O, eliminating level-shifter BOM cost and PCB area. |
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; no TSOP pins | Requires BGA reflow assembly; unsuitable for through-hole or socketed designs | Select for space-constrained PCBs where 8.15 × 6.15 mm footprint is mandatory |
| MX29GL32EHXFI-90G | Macronix 32 Mbit Flash; 90 ns access, but uses different command set and lacks Secured Silicon Sector | No factory-programmed ESN; password protection requires external management | Select only when CFI compatibility and secure identity are not required; verify bootloader command mapping |
Compared with S29GL032N90FFI033, the TSOP-packaged alternative offers identical functionality in legacy-compatible form factor, while the Macronix part trades security and JEDEC alignment for lower unit cost - making it viable only in cost-sensitive, non-secure applications.

FAQ
What is the function of the WP#/ACC pin on S29GL032N90FFI033?
The WP#/ACC pin serves dual roles: when driven low, it hardware-protects the first or last sector regardless of software protection settings; when driven high with elevated voltage (VHH ≈ 11.5 V), it enables accelerated programming for faster factory throughput. This dual-mode operation is confirmed in the datasheet's Section 8.16 and Figure 1 pin diagram.
Does S29GL032N90FFI033 support x8 data bus mode?
Yes - the BYTE# input selects bus width: logic high enables x16 mode (DQ0–DQ15 active); logic low configures x8 mode (DQ0–DQ7 only). In x8 mode, DQ15 functions as A-1 for address extension, and the device presents 4,194,304 × 8-bit organization. This is specified in Section 8.1 and Figure 1.
How does the Secured Silicon Sector differ from standard sectors?
The Secured Silicon Sector is a dedicated 128-word (256-byte) region pre-programmed with an 8-word electronic serial number at factory. Once locked via command sequence, it becomes permanently read-only and immune to erase or program commands - unlike standard sectors, which remain fully reprogrammable. Details are in Section 8.15.
Can S29GL032N90FFI033 be used with a 1.8 V I/O interface?
Yes - the VIO pin accepts 1.65–3.6 V, so applying 1.8 V to VIO sets all input thresholds and output drive levels for 1.8 V logic compatibility. VCC remains at 2.7–3.6 V for core operation. This VersatileI/O™ feature eliminates external level shifters and is verified in Section 1.2 and Table 15.1 AC characteristics.
