Product details
Overview
S29GL032N11FFIS40 from Infineon Technologies (formerly Cypress) is a 32-Mbit (4,194,304-byte), 16-bit-wide single-supply MirrorBit Flash memory IC with uniform sector architecture (64 × 64 KB sectors), 90 ns access time, and 100,000 erase cycles per sector - deployed in industrial control firmware storage and boot code retention applications.
For engineers reviewing the S29GL032N11FFIS40 datasheet, S29GL032N11FFIS40 pinout, S29GL032N11FFIS40 application, or S29GL032N11FFIS40 equivalent, key selection criteria include VIO-supported VersatileI/O™ operation (1.65–3.6 V), CFI compliance for host auto-configuration, Secured Silicon Sector with factory-programmed 16-byte ESN, and hardware write protection via WP#/ACC pin.
Technical Context
This device implements a JEDEC-standard command-set-compatible Flash memory core using 110 nm MirrorBit process technology, supporting both byte (via BYTE#) and word-level access. It features dual status reporting via DQ7 Data# Polling and DQ6 Toggle Bit I, plus RY/BY# hardware signaling for program/erase completion detection.
The architecture includes dedicated erase voltage and programming voltage generators, on-chip timers, and a state controller that latches addresses/data during internal operations. Sector erase granularity enables selective reprogramming without disturbing adjacent firmware regions, while persistent and password-based sector protection mechanisms enforce secure boot partitioning.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 32 Mbit (4,194,304 bytes), organized as 2,097,152 × 16-bit words - supports full firmware image storage for mid-complexity microcontrollers. |
| Access Time | 90 ns at VCC = 2.7–3.6 V and VIO = 2.7–3.6 V - enables direct interface with legacy 80 MHz bus systems without wait states. |
| Erase Endurance | 100,000 cycles per sector - ensures field-upgradable firmware partitions retain reliability over 10+ years of maintenance cycles. |
| Data Retention | 20 years at 125 °C - validated for automotive under-hood and industrial high-temperature deployment. |
| Supply Voltage | Single 3.0 V supply (VCC = 2.7–3.6 V); VIO independently configurable 1.65–3.6 V - decouples I/O logic level from core voltage for mixed-signal SoC interfacing. |
| Page Read Buffer | 8-word (16-byte) page read buffer with 25 ns page access - accelerates sequential instruction fetch in boot ROM mode. |
| Write Buffer | 16-word (32-byte) write buffer - reduces multi-word programming overhead by batching writes before internal commit. |
Pinout & Package
Package: 48-ball fine-pitch BGA (VBK048, 8.15 × 6.15 mm, 0.8 mm pitch). Ball grid layout conforms to JEDEC MO-245AC standard.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A20 | Address Inputs | 21-bit address bus supporting full 32 Mbit addressing; A-1 used as DQ15 multiplex in x16 mode. |
| DQ0–DQ15 | Data/Address Multiplexed I/O | 16-bit bidirectional data bus; DQ15 doubles as A-1 in x16 configuration - enables compact address decoding. |
| CE#, OE#, WE# | Chip/Output/Write Enable Controls | Independent active-low enables allow interleaved read/write arbitration and partial memory mapping in multi-device systems. |
| WP#/ACC | Write Protect / Accelerated Program Input | Hardware lock for first/last sector; when driven high with 5.5 V, enables accelerated programming for production throughput. |
| RY/BY# | Ready/Busy Output | Open-drain status signal indicating active program/erase - eliminates need for software polling in real-time systems. |
| RESET# | Hardware Reset Input | Asynchronous reset terminates ongoing operations and restores device to known state - critical for safe boot recovery. |
| BYTE# | Bus Width Select | Configures x16 or x8 data interface; enables compatibility with 8-bit microcontrollers without external demux logic. |
| VIO | I/O Supply Reference | Defines input threshold and output drive level independently of VCC - supports mixed-voltage system integration. |
Key Features
| Feature | Design Value |
|---|---|
| Secured Silicon Sector | 128-word (256-byte) factory-locked region with 16-byte electronic serial number - provides immutable device identity for secure boot chain binding. |
| Advanced Sector Protection | Persistent and Password Sector Protection modes - enforce read/write lockdown of boot sectors independent of power cycle or reset events. |
| Program/Erase Suspend | Pause active programming or erasing to service higher-priority reads from other sectors - enables real-time firmware updates without system stall. |
| CFI Compliance | JEDEC JESD68-defined Common Flash Interface - allows host BIOS or bootloader to auto-detect geometry, timing, and command set without hard-coded assumptions. |
| VersatileI/O™ Control | VIO pin sets all input thresholds and output levels - simplifies interface design across 1.8 V, 2.5 V, and 3.3 V host logic families. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S29GL032N10TFI010 | Same die, 48-pin TSOP package (vs. 48-ball BGA); 110 ns access time (vs. 90 ns); no VIO pin - fixed 3.0 V I/O logic. | Limited to PCBs with TSOP footprint and lower-speed buses; lacks VIO flexibility for mixed-voltage designs. | Select when board layout constraints prohibit BGA or when cost-sensitive consumer applications tolerate slower access. |
| MX29GL320EBTI-90G | 32 Mbit, 90 ns, 48-pin TSOP; Macronix part with identical JEDEC command set but no Secured Silicon Sector or Password Protection. | Cannot support secure boot chains requiring factory-locked identity or password-gated sector writes. | Choose for non-security-critical applications where CFI compatibility and basic sector erase suffice, and TSOP mounting is preferred. |
Compared with S29GL032N11FFIS40, the TSOP alternatives trade package flexibility and security features for simpler assembly or lower unit cost - whereas the Infineon part delivers BGA space savings, VIO-driven interoperability, and hardware-enforced firmware integrity essential for certified industrial and automotive systems.

FAQ
What is the function of the VIO pin on S29GL032N11FFIS40?
The VIO pin defines input voltage thresholds and output drive levels for all address, control, and data signals - enabling operation with 1.65–3.6 V I/O logic independently of the 2.7–3.6 V VCC supply. This allows seamless interfacing with 1.8 V, 2.5 V, or 3.3 V host processors without level shifters.
Does S29GL032N11FFIS40 support byte-level writes?
No - it supports only word-level (16-bit) writes in x16 mode or byte-level access only via BYTE#-enabled x8 mode, where DQ0–DQ7 carry data and DQ8–DQ15 are unused. True byte programming is not supported; minimum write granularity remains one word (2 bytes) in x16 configuration.
How is the Secured Silicon Sector protected after factory programming?
Once programmed and locked, the 128-word Secured Silicon Sector becomes permanently read-only - no command sequence, voltage condition, or reset event can unlock or rewrite its contents. The 16-byte electronic serial number is factory-laser-fused and accessible only via defined command sequences, ensuring tamper-resistant device identification.
Can S29GL032N11FFIS40 be used in place of older S29GL032P devices?
No - the S29GL032N uses MirrorBit technology and a different command set than the floating-gate-based S29GL032P. Although density and pinout may appear similar, differences in erase algorithms, status reporting (DQ6/DQ7 behavior), and CFI structure prevent drop-in replacement without firmware revision and validation.
