Product details
Overview
S29GL032N90TFA023 from Cypress Semiconductor is a 32-Mbit (4,194,304-byte), 16-bit wide, single-supply 3.0 V MirrorBit Flash memory with 90 ns access time, uniform sector architecture (64 × 64 KB sectors), and Secured Silicon Sector for factory-programmed 256-byte electronic serial number. It operates in embedded boot code storage applications requiring fast page read (25 ns), low standby current (1 µA), and hardware reset (RESET#) support.
For engineers reviewing the S29GL032N90TFA023 datasheet, S29GL032N90TFA023 pinout, S29GL032N90TFA023 application, or S29GL032N90TFA023 equivalent, key selection criteria include JEDEC-compliant command set, VIO-referenced I/O (1.65–3.6 V), CFI compliance for host auto-identification, and hardware write protection via WP#/ACC pin.
Technical Context
This device implements a 110 nm MirrorBit floating-gate NOR architecture with hot-hole erase and hot-electron programming. It supports byte/word configuration via BYTE# input and uses separate CE#, OE#, and WE# controls for precise bus timing.
Its command-set compatibility with JEDEC JESD21-C ensures interoperability with legacy flash controllers. The Secured Silicon Sector is permanently locked post-factory and accessible only via dedicated unlock/enter commands-no reprogramming allowed after lock.
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 and VIO = 2.7–3.6 V - defines minimum clock period for synchronous read cycles |
| Page Read Time | 25 ns - enables burst reads of up to 8 words (16 bytes) without address re-latching |
| Write Buffer Size | 16-word (32-byte) buffer - reduces multi-word programming overhead by batching writes |
| Endurance | 100,000 erase/program cycles per sector - specifies maximum field rewrites before wear-out |
| Data Retention | 20 years at 125 °C - guaranteed data integrity under industrial temperature stress |
| Standby Current | 1 µA typical - enables ultra-low-power hold state during system sleep modes |
Pinout & Package
Package: 48-pin TSOP (Type 1, standard thin small outline package, 12 × 20 mm body, 0.5 mm pitch).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A21 | Address Inputs | 22-bit address bus supporting full 4 MB addressing space; A-1 used as DQ15 in x16 mode |
| DQ0–DQ15 | Data I/O | 16-bit bidirectional data bus; DQ15 doubles as A-1 in x16 configuration per JEDEC standard |
| CE# | Chip Enable | Active-low chip select; device enters standby when deasserted and no other control active |
| OE# | Output Enable | Active-low read strobe; controls output drivers independently of CE# for multiplexed bus sharing |
| WE# | Write Enable | Active-low write strobe; latches command/data on rising edge for internal state machine transition |
| WP#/ACC | Write Protect / Accelerated Program | Low = hardware sector protection (first/last sector); high + VHH = accelerated programming for production throughput |
| RESET# | Hardware Reset | Active-low asynchronous reset; terminates all operations and returns device to read array state |
| RY/BY# | Ready/Busy Output | Open-drain status flag; low = device busy (erase/program in progress), high = ready for next command |
| BYTE# | Bus Width Select | Low = x16 mode (16-bit data path); high = x8 mode (DQ0–DQ7 only active, DQ8–DQ15 ignored) |
| VIO | I/O Supply Reference | Input voltage reference (1.65–3.6 V) setting logic thresholds for all address/control/data pins - decouples I/O from core VCC |
Key Features
| Feature | Design Value |
|---|---|
| Secured Silicon Sector | 256-byte factory-programmable region with permanent lock - provides immutable device identity for secure boot or licensing |
| CFI Compliance | JEDEC-standard Common Flash Interface - enables automatic detection and parameter negotiation by host bootloader firmware |
| Program/Erase Suspend | Allows interrupting active program/erase to service higher-priority reads from other sectors - critical for real-time OS coexistence |
| Unlock Bypass Mode | Reduces multi-word programming from 4-cycle to 2-cycle command sequence - cuts firmware update latency by ~50% |
| Persistent Sector Protection | Non-volatile lock bits disable program/erase in selected sectors without external voltage - eliminates need for 12-V protection circuitry |

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; identical timing and command set | Requires PCB redesign for BGA layout and reflow profile; better thermal dissipation in dense layouts | Select for space-constrained designs where TSOP footprint is prohibitive and automated optical inspection is available. |
| MX29GL32EHXFI-90G | Macronix 32 Mb NOR Flash; 90 ns access, but uses different command set (non-JEDEC) and lacks Secured Silicon Sector | No factory-programmed serial number; requires software-based security implementation for secure boot | Select only if CFI compliance and hardware-secured identity are not required, and firmware can accommodate vendor-specific commands. |
Compared with S29GL032N90TFA023, the TSOP-packaged S29GL032N90TFI020 offers identical functionality in a smaller footprint but demands BGA assembly capability, while the MX29GL32EHXFI-90G sacrifices JEDEC compatibility and hardware security for lower unit cost in non-secure applications.

FAQ
What is the function of the VIO pin on S29GL032N90TFA023?
The VIO pin sets the input voltage reference for all address, control, and data I/O pins, enabling operation across 1.65–3.6 V independent of the core VCC supply (2.7–3.6 V). This allows direct interfacing with 1.8 V or 3.3 V logic without level shifters, and determines logic thresholds for CE#, OE#, WE#, and DQ signals.
Does S29GL032N90TFA023 support both x8 and x16 data bus widths?
Yes - the BYTE# pin selects bus width: asserted low enables full 16-bit mode (DQ0–DQ15 active), while high configures x8 mode (only DQ0–DQ7 used, DQ8–DQ15 tri-stated). This flexibility supports migration between 8-bit and 16-bit microcontroller interfaces without changing the memory device.
How is the Secured Silicon Sector protected from modification?
The Secured Silicon Sector is permanently locked at the factory or by the customer using a dedicated command sequence; once locked, no further programming or erasure is possible. Access requires an unlock command followed by a specific entry sequence, but the lock itself is irreversible - ensuring the 256-byte electronic serial number remains tamper-proof throughout device life.
Can S29GL032N90TFA023 be used in place of older AMD/Spansion S29GLxxx devices?
Yes - it maintains full pin and command compatibility with legacy Spansion S29GL032N variants (e.g., S29GL032N90TFI020, S29GL032N90TFI010), including identical TSOP-48 footprint, JEDEC command set, and timing parameters. No firmware or hardware changes are needed for drop-in replacement in existing designs.
