Product details
Overview
S29GL032N90FFIS20 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 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 industrial control firmware storage where deterministic boot code integrity and long-term data retention are required.
For engineers reviewing the S29GL032N90FFIS20 datasheet, S29GL032N90FFIS20 pinout, S29GL032N90FFIS20 application, or S29GL032N90FFIS20 equivalent, key selection criteria include JEDEC-compliant command set compatibility, hardware write protection via WP#/ACC, CFI compliance for host auto-configuration, and support for program/erase suspend-resume operations in embedded boot memory systems.
Technical Context
This device implements a 110 nm MirrorBit floating-gate NAND-like cell architecture enabling single-power 3.0 V operation with hot-electron programming and hot-hole assisted erase. It features dual voltage domains: VCC powers core logic and array, while VIO independently sets I/O buffer thresholds (1.65–3.6 V), allowing interoperability with 1.8 V or 3.3 V host buses.
The memory is organized as 64 uniform 64 KB sectors (2,097,152 words), supports byte/word configuration via BYTE# input, and includes dedicated hardware signals-RY/BY#, RESET#, and WP#/ACC-for real-time operation monitoring, system reset synchronization, and accelerated factory programming with sector-level write lock enforcement.
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 max at VCC = 2.7–3.6 V - enables direct execution from flash in 25 MHz bus systems |
| Page read time | 25 ns - supports high-throughput sequential reads using 8-word internal buffer |
| Erase endurance | 100,000 cycles per sector - validated for firmware update partitions in field-deployed equipment |
| Data retention | 20 years typical at 125°C - meets extended-life requirements for automotive and industrial control modules |
| VIO range | 1.65–3.6 V - allows direct interface to 1.8 V microcontrollers without level shifters |
| Supply voltage | Single 2.7–3.6 V VCC - eliminates need for auxiliary voltage rails in space-constrained designs |
Pinout & Package
Package: 48-pin TSOP (Type 1, standard thin small outline package), lead pitch 0.5 mm, body size 12 × 20 mm. Pinout conforms to JEDEC MO-142AC standard for 48-pin Flash devices.
| 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 | 16-bit bidirectional data bus; DQ15 doubles as A-1 for x8/x16 configuration detection |
| CE#, OE#, WE# | Chip, output, write enable controls | Independent gating enables interleaved read/write and partial-memory access without full chip select |
| WP#/ACC | Write protect / accelerated program input | Low-active hardware lock for first/last sector; high-voltage mode reduces programming time during production |
| RY/BY# | Ready/Busy output | Open-drain active-low signal indicating ongoing program/erase - enables non-polling interrupt-driven host control |
| RESET# | Hardware reset input | Asynchronous active-low reset that terminates all operations and restores command interface state |
| BYTE# | Bus width configuration | High = x16 mode; low = x8 mode with DQ0–DQ7 only active - supports legacy 8-bit host interfaces |
| VIO | I/O voltage reference | Sets input threshold and output drive strength independently of VCC - critical for mixed-voltage system integration |
Key Features
| Feature | Design Value |
|---|---|
| Secured Silicon Sector | 128-word (256-byte) factory-locked region with 8-word electronic serial number - provides immutable device identity for secure boot and anti-cloning |
| Program/Erase Suspend-Resume | Allows host to pause active programming or erasing to service higher-priority reads - essential for real-time OS environments |
| CFI compliance | Enables automatic detection of device geometry, timing, and command set by host bootloader - eliminates hard-coded flash parameters |
| Unlock Bypass mode | Reduces multi-word programming overhead from 4 to 2 write cycles - improves firmware update throughput by ~35% |
| Persistent Sector Protection | Non-volatile lock bits disable program/erase in selected sectors without requiring external voltage - replaces obsolete 12 V protection schemes |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S29GL032N90TFIR20 | Same die, 48-ball fine-pitch BGA (VBK048) package; no TSOP pins | Used in high-density PCBs where board area is constrained and reflow assembly is standard | Select when footprint miniaturization and thermal performance outweigh hand-solderability needs |
| MX29GL320EBTI-90G | 32 Mbit, 90 ns, but uses 1.8 V core + 3.3 V I/O; different command set; no Secured Silicon Sector | Targets low-power portable systems; lacks factory-locked serial ID and persistent protection bits | Choose only if VCC < 2.7 V operation is mandatory and security features are not required |
Compared with S29GL032N90FFIS20, the TSOP-packaged alternative offers identical functionality in a through-hole-compatible form factor, while the MX29GL320E variant trades security and voltage flexibility for lower active current - making it unsuitable for industrial boot applications requiring long-term data integrity and tamper resistance.

FAQ
What is the function of the VIO pin on S29GL032N90FFIS20?
VIO sets the input threshold voltage and output drive strength for all address, control, and data pins independently of VCC. It accepts 1.65–3.6 V, enabling direct interfacing with 1.8 V or 3.3 V host processors without external level shifters. This dual-voltage capability simplifies mixed-signal system design and reduces BOM count.
Does S29GL032N90FFIS20 support both x8 and x16 data bus widths?
Yes. When BYTE# is driven low, the device operates in x8 mode with DQ0–DQ7 active; when BYTE# is high, it operates in x16 mode with DQ0–DQ15 active. The A-1 address bit is multiplexed onto DQ15 in x16 mode, allowing automatic bus-width detection by the host during initialization.
How does the Secured Silicon Sector differ from standard flash sectors?
The Secured Silicon Sector is a dedicated 128-word (256-byte) region pre-programmed with a unique 8-word electronic serial number at the factory. Once locked, it cannot be erased or rewritten - even with full device erase commands. It is accessed via a specific command sequence and provides immutable device identification for secure boot and anti-counterfeiting.
Can S29GL032N90FFIS20 be used in systems requiring -40°C to +105°C operation?
Yes. The S29GL032N90FFIS20 is rated for industrial temperature range (-40°C to +85°C) and extended temperature range (-40°C to +105°C) per ordering option. The "I" in the part number suffix (e.g., IS20) denotes industrial grade; the "S20" suffix confirms 105°C maximum junction temperature rating and qualification per AEC-Q100 stress tests for automotive use cases.
