Product details
Overview
S29GL128N11TFI020 from Cypress Semiconductor is a 128 Mbit (16 MB), 3.0 V single-power-supply NOR Flash memory using 110 nm MirrorBit technology, organized as 8,388,608 words × 16 bits, with 90 ns access time, 25 ns page read time, and 100,000 erase cycles per sector. It operates in TSOP-56 package with VIO support from 1.65 V to VCC and features Secured Silicon Sector for electronic serial number storage.
For engineers reviewing the S29GL128N11TFI020 datasheet, S29GL128N11TFI020 pinout, S29GL128N11TFI020 application, or S29GL128N11TFI020 equivalent, key selection criteria include JEDEC-compliant command set, hardware reset (RESET#) and ready/busy (RY/BY#) signaling, flexible sector protection modes, CFI compliance, and 1.65–3.6 V VIO voltage range compatibility.
Technical Context
This device implements a parallel-interface NOR Flash architecture with separate CE#, OE#, and WE# controls, enabling standard microprocessor bus interfacing. Its sector erase model supports independent 64 Kword (128 KB) sector erasure across 128 sectors, and its Enhanced VersatileI/O™ control allows dynamic I/O voltage level adaptation via the VIO pin.
The internal state machine handles all programming and erase operations via command sequences, with status monitored through DQ7 polling, DQ6 toggle bits, or RY/BY# output. Hardware data protection includes low-VCC detection, persistent sector lock, password-based sector protection, and WP#/ACC-accelerated programming for production throughput.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 128 Mbit (8,388,608 × 16-bit words), enabling boot code and firmware storage in resource-constrained embedded systems. |
| Access Time | 90 ns (at VCC = 3.0–3.6 V, VIO = 3.0–3.6 V), supporting high-speed CPU fetch cycles without wait states. |
| Page Read Time | 25 ns, allowing rapid sequential reads from the 8-word page buffer to accelerate firmware execution. |
| Erase Endurance | 100,000 cycles per sector, ensuring long-term field reliability for infrequently updated configuration or calibration data. |
| Data Retention | 20 years (typical), maintaining integrity of stored boot images and security keys over product lifetime. |
| VIO Range | 1.65 V to VCC, permitting interoperability with both 1.8 V and 3.3 V host logic without level shifters. |
| Supply Voltage | 2.7–3.6 V VCC, compatible with standard 3 V system rails and tolerant of brown-out conditions. |
Pinout & Package
Package: 56-pin TSOP (Thin Small Outline Package), lead-free and RoHS-compliant, with standard JEDEC MO-142AC footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A22 | Address Inputs | 23-bit address bus supporting full 128 Mbit addressing (A22 = MSB); BYTE# enables 8-bit mode. |
| DQ0–DQ15 | Data I/O | 16-bit bidirectional data bus; functions as 8-bit when BYTE# = LOW, reducing bus width for legacy controllers. |
| CE# | Chip Enable | Active-low chip select; device enters standby when deasserted, reducing current to 1 µA typical. |
| OE# | Output Enable | Active-low output gate; controls data bus drivers during read operations only. |
| WE# | Write Enable | Active-low write strobe; latches addresses/data for command execution and programming/erase initiation. |
| RESET# | Hardware Reset | Active-low asynchronous reset; terminates ongoing operations and returns device to read mode for safe reboot. |
| RY/BY# | Ready/Busy Output | Open-drain status signal indicating active program/erase; used for hardware flow control without polling. |
| WP#/ACC | Write Protect / Accelerate | Low = sector protection; high + VCC = accelerated programming (shorter pulse width, higher current). |
| VIO | I/O Voltage Reference | Defines input threshold and output drive levels for all address/control/data pins; decouples I/O from core VCC. |
Key Features
| Feature | Design Value |
|---|---|
| Secured Silicon Sector | 128-word (256-byte) factory-lockable region storing unique 8-word electronic serial number for device authentication. |
| Program/Erase Suspend | Allows interruption of active program or erase to service real-time read requests from other sectors-critical for multitasking firmware. |
| CFI Compliance | Enables automatic identification and configuration by host BIOS/bootloader without hard-coded timing or geometry assumptions. |
| Password Sector Protection | 64-bit user-defined password required to unlock protected sectors, preventing unauthorized firmware modification or reverse engineering. |
| Enhanced VersatileI/O™ | VIO pin dynamically sets I/O voltage thresholds, eliminating external level shifters when interfacing with mixed-voltage SoCs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NOR Flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S29GL128S11TFI020 | Successor part using 90 nm process; 85 ns access time; supports deeper sleep mode (0.5 µA standby). | Same pinout and command set; requires no PCB change but offers improved power efficiency in battery-backed systems. | Select for new designs requiring extended lifecycle support and lower static power. |
| MX29GL128FHI-90G | Macronix equivalent; 90 ns access; identical TSOP-56 package; supports CFI but lacks Secured Silicon Sector. | Drop-in replacement for basic boot storage; missing electronic serial number and password protection features. | Select when cost sensitivity outweighs secure identity and firmware anti-tamper requirements. |
Compared with S29GL128N11TFI020, the S29GL128S11TFI020 delivers measurable power and timing improvements while maintaining full compatibility, whereas the MX29GL128FHI-90G trades security features for cost reduction in non-secure applications.

FAQ
Is S29GL128N11TFI020 still in production?
No - Cypress discontinued the S29GL128N family in 2016 and explicitly states "Not Recommended for New Design." However, Aetrix Electronics maintains limited legacy inventory sourced from authorized channels with full traceability and extended lifecycle support for existing production programs.
Can S29GL128N11TFI020 be used with a 1.8 V I/O interface?
Yes - the VIO pin accepts 1.65 V to VCC, so applying 1.8 V to VIO configures all inputs and outputs to 1.8 V logic levels, enabling direct connection to 1.8 V SoCs without level-shifting circuitry, provided VCC remains within 2.7–3.6 V.
What is the function of the WP#/ACC pin during normal operation?
When held LOW, WP#/ACC protects the first or last sector from accidental writes or erases. When driven HIGH with VCC applied, it enables accelerated programming mode, reducing pulse width and increasing current to cut programming time by ~30% - primarily used in manufacturing test and burn-in.
Does S29GL128N11TFI020 support execute-in-place (XIP) operation?
Yes - its 90 ns random access time and parallel interface allow direct CPU instruction fetch from flash memory without copying to RAM, enabling XIP boot architectures common in ARM Cortex-M and PowerPC-based embedded systems.
