Product details
Overview
S29GL032N90TFI023 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- or customer-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 S29GL032N90TFI023 datasheet, S29GL032N90TFI023 pinout, S29GL032N90TFI023 application, or S29GL032N90TFI023 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 NOR Flash architecture with hot-hole erase and hot-electron programming. It features separate CE#, WE#, and OE# controls, supports both word and byte configuration via BYTE# input, and uses VIO to define all I/O voltage thresholds - enabling interoperability with mixed-voltage host systems.
The Secured Silicon Sector provides 256-byte factory-lockable space with permanent read-only access after programming. Advanced Sector Protection includes Persistent Sector Protection (PPB-based) and Password Sector Protection, both implemented in hardware without external controllers or firmware dependencies.
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 and VIO = 2.7–3.6 V - enables direct CPU bus interfacing without wait states in 33 MHz bus systems |
| Erase endurance | 100,000 cycles per sector - supports field firmware updates over product lifetime in industrial gateways |
| Data retention | 20 years typical at 125 °C - validated for automotive under-hood and industrial high-temp storage |
| 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 eliminating per-word command overhead |
| Standby current | 1 µA typical - meets low-power requirements for battery-backed firmware storage in edge sensors |
Pinout & Package
Package: 48-pin TSOP (Type I, standard thin small outline package, 12 × 20 mm body).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A21 | Address inputs | 22-bit address bus supporting full 4 MB addressing; A-1 (DQ15/A-1) multiplexed for byte/word mode selection |
| DQ0–DQ15 | Data I/O bidirectional bus | 16-bit data path; DQ15 functions as A-1 in byte mode when BYTE# = low |
| CE# | Chip enable | Active-low chip select; device enters standby when CE# high and addresses stable |
| WE# | Write enable | Controls write latching; initiates command execution or data programming on falling edge |
| OE# | Output enable | Enables output drivers during read; does not affect internal state or timing of erase/program |
| WP#/ACC | Write protect / accelerated program | Low = hardware sector lock (first/last sector); high + VHH = 2× faster programming in production |
| RY/BY# | Ready/Busy indicator | Open-drain active-low output signaling completion of program/erase without polling |
| RESET# | Hardware reset | Aborts ongoing operation and returns device to read mode; tied to system reset for boot recovery |
Key Features
| Feature | Design Value |
|---|---|
| Secured Silicon Sector | 256-byte factory- or user-lockable region with 16-byte ESN - enables secure device identity binding in IoT node provisioning |
| VersatileI/O™ Control | VIO pin sets all I/O thresholds (1.65–3.6 V) - eliminates level shifters when interfacing with 1.8 V or 3.3 V microcontrollers |
| Program/Erase Suspend-Resume | Pause active programming or erasing to service higher-priority reads - essential for real-time boot loaders accessing multiple firmware partitions |
| CFI Compliance | Standardized query table at 0x0055, 0x0055, 0x00AA - allows generic flash driver initialization without part-specific code |
| Unlock Bypass Mode | Two-cycle instead of four-cycle command sequence for multi-word writes - reduces firmware update time by ~35% in host-controlled reprogramming |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S29GL032N11TFI020 | 110 ns access time; same 32 Mbit density, uniform sector, and package; lower speed grade | Acceptable where CPU bus runs ≤25 MHz or wait states are tolerable | Select for cost-sensitive designs with relaxed timing budgets and identical feature set |
| MX29GL320EBTI-90G | Macronix 32 Mbit NOR Flash; 90 ns access; 48-pin TSOP; JEDEC-compatible but no Secured Silicon Sector | Lacks factory-programmable ESN and persistent password protection | Choose when advanced security features are unnecessary and second-source qualification is required |

FAQ
What is the function of the WP#/ACC pin on S29GL032N90TFI023?
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 an accelerated voltage (VHH ≈ 11.5 V), it enables faster programming for production throughput. This pin is electrically isolated from VCC and requires external voltage generation only during accelerated programming - not during normal operation.
Does S29GL032N90TFI023 support byte-wide data access?
Yes - the device supports 8-bit data access using the BYTE# input. When BYTE# is low, DQ0–DQ7 operate as an 8-bit data bus while DQ8–DQ15 are tri-stated; when BYTE# is high, the full 16-bit bus is active. This mode is fully compatible with x8/x16 microcontroller buses and requires no external glue logic.
