Product details
Overview
S29GL512P11TFIV20 from Cypress Semiconductor (acquired by Infineon) is a 512 Mbit (64 MB), 3.0 V-only, page-mode NOR Flash memory fabricated on 90 nm MirrorBit process technology. It delivers 100 ns random access time and 25 ns page access time, features a 32-word/64-byte write buffer, uniform 64 Kword sectors (512 total), and supports CFI for host compatibility - deployed in industrial control firmware storage and boot code retention.
For engineers reviewing the S29GL512P11TFIV20 datasheet, S29GL512P11TFIV20 pinout, S29GL512P11TFIV20 application, or S29GL512P11TFIV20 equivalent, key selection criteria include sector erase endurance (100,000 cycles), Secured Silicon Sector with factory-programmable ESN, VersatileI/O™ voltage flexibility (VIO = 1.65–VCC), and hardware reset (RESET#) with Ready/Busy# status signaling.
Technical Context
This device implements a synchronous command-set architecture with autoselect, program suspend/resume, and dual protection methods (Persistent Lock Bits and Password). Its VersatileI/O™ interface decouples I/O voltage (VIO) from core supply (VCC), enabling interoperability with 1.8 V, 2.5 V, or 3.3 V logic domains while maintaining full 3.0 V operation for programming and erasing.
The memory array is organized into 512 uniform 64 Kword (128 Kbyte) sectors. Each sector supports independent erase, and the Secured Silicon Sector provides a dedicated 128-word (256-byte) region with lockable 8-word electronic serial number - accessible only via specific unlock sequences and protected against accidental overwrite.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 512 Mbit (64 MB) - supports full firmware images for mid-complexity embedded systems without external expansion. |
| Access Time | 100 ns random / 25 ns page - enables direct XIP (eXecute-In-Place) execution of boot code from flash with minimal latency penalty. |
| Write Buffer Size | 32 words (64 bytes) - reduces effective multi-word programming time by >70% vs. single-word writes, accelerating field firmware updates. |
| Sector Count & Size | 512 × 64 Kword (128 Kbyte) sectors - allows fine-grained firmware partitioning (e.g., separate bootloader, app, config sectors) with independent protection. |
| Erase Endurance | 100,000 cycles per sector - qualifies for industrial applications requiring frequent field-upgradable configuration or logging data. |
| Data Retention | 20 years typical - ensures long-term reliability in unpowered storage for medical, energy, or infrastructure equipment. |
| Supply Voltage | VCC = 2.7–3.6 V; VIO = 1.65–VCC - supports mixed-voltage system integration without level shifters for address/data/control lines. |
Pinout & Package
Package: 56-pin TSOP (Standard Thin Small Outline Package, TSO56), lead-free (Pb-free), industrial temperature range (–40°C to +85°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A24–A0 | Address Inputs | 25-bit address bus (A24–A0); A24 is MSB for 512 Mbit addressing up to 64 MB space. |
| DQ15–DQ0 | Data I/O (Word Mode) | 16-bit bidirectional data bus; DQ15/A-1 serves as LSB address in byte mode when BYTE# = VIL. |
| CE#, OE#, WE# | Chip/Output/Write Enable | Standard asynchronous NOR interface controls - enables standard microcontroller or FPGA memory-mapped access. |
| RY/BY# | Ready/Busy Output | Active-low open-drain signal indicating active program/erase; used for polling or interrupt-driven status monitoring. |
| RESET# | Hardware Reset Input | Asynchronous reset that terminates ongoing operations and returns device to read mode - critical for safe power-cycle recovery. |
| WP#/ACC | Write Protect / Acceleration | VIL = protects top/bottom sector; VHH = enables accelerated programming and auto-unlock bypass - used in production line programming. |
| VIO | Versatile I/O Supply | Independent I/O voltage reference (1.65–VCC); sets input thresholds and output drive strength - eliminates need for external level shifters. |
Key Features
| Feature | Design Value |
|---|---|
| Secured Silicon Sector | 128-word (256-byte) factory- or customer-lockable region containing programmable 8-word ESN - enables secure device identification and anti-cloning in OEM deployments. |
| Advanced Sector Protection | Persistent lock bits + password method - allows permanent or dynamic sector locking without volatile registers, meeting industrial security requirements. |
| Write Buffer Programming | 32-word burst programming reduces average write time to 15 µs/word (VCC) or 13.5 µs/word (VHH) - cuts firmware update duration by >4× vs. legacy single-word algorithms. |
| Uniform Sector Architecture | All 512 sectors are identical 64 Kword size - simplifies software driver development and avoids complex sector mapping logic in bootloader code. |
| CFI Compliance | Common Flash Interface v1.3 support - enables automatic detection and configuration by standard flash drivers (e.g., U-Boot, Linux MTD) without vendor-specific code. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NOR Flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S29GL512S11TFIV20 | Same density and package, but uses 65 nm Eclipse MirrorBit process; slightly lower standby current (0.5 µA vs. 1 µA) and faster 90 ns random access. | Preferred where ultra-low power sleep mode or marginally higher speed is required; not drop-in due to timing and command set differences. | Select only if migrating to newer Spansion/Infineon generation with updated firmware validation. |
| MX29GL512FHI-11G | Macronix 512 Mbit NOR Flash; same TSOP-56 package, 110 ns access, but lacks Secured Silicon Sector and VersatileI/O™ - fixed 3.3 V I/O. | Suitable for cost-sensitive designs without security or mixed-voltage needs; requires external level shifting if interfacing with sub-3.3 V logic. | Choose when ESN, sector locking, or VIO flexibility are not required - lowers BOM and qualification effort. |

FAQ
What is the function of the VIO pin on the S29GL512P11TFIV20?
The VIO pin sets the input voltage threshold and output drive strength for all address, control, and data signals. It operates independently from VCC and accepts 1.65 V to VCC, enabling direct interface with 1.8 V, 2.5 V, or 3.3 V logic without external level shifters - a key enabler for mixed-voltage system design.
Does the S29GL512P11TFIV20 support hardware reset during active programming?
Yes. The RESET# input is asynchronous and forces immediate termination of any ongoing program or erase operation, returning the device to read mode. This ensures safe recovery from power faults or watchdog timeouts without risking memory corruption - confirmed in Section 9.3 of the datasheet.
How many sectors does the S29GL512P11TFIV20 have, and what is their size?
The device contains exactly 512 uniform sectors, each sized at 64 Kwords (128 Kbytes). This architecture is explicitly defined in the "Uniform Sector Architecture" section and verified in the ordering information table - enabling predictable firmware layout and simplified driver implementation.
Can the Secured Silicon Sector be programmed after initial factory setup?
Yes. While factory-programmed ESN is common, the Secured Silicon Sector is fully customer-programmable and lockable via documented command sequences. Once locked using the Persistent Protection Bit Lock Bit, further writes are permanently disabled - providing flexible yet irreversible security deployment.
