Product details
Overview
S29GL256P10TFI010 from Cypress Semiconductor is a 256 Mbit (32 MB) single-voltage 3.0 V page-mode NOR Flash memory fabricated on 90 nm MirrorBit process technology, featuring 256 uniform 128 Kbyte sectors, 25 ns page access time, and 100 ns random access time under regulated VCC. It supports VersatileI/O™ with VIO range 1.65–VCC, 32-word write buffer, and Secured Silicon Sector with factory-programmable 256-byte serial ID - deployed in industrial-grade embedded controllers requiring nonvolatile code storage and field firmware updates.
For engineers reviewing the S29GL256P10TFI010 datasheet, S29GL256P10TFI010 pinout, S29GL256P10TFI010 application, or S29GL256P10TFI010 equivalent, key selection criteria include sector erase endurance (100,000 cycles), data retention (20 years), WP#/ACC acceleration support, CFI compliance, and TSOP-56 industrial temperature operation (–40°C to +85°C).
Technical Context
This device implements a synchronous/asynchronous hybrid interface with dedicated CE#, OE#, and WE# controls, enabling direct microprocessor bus interfacing without glue logic. Its architecture integrates an on-chip state machine for embedded program/erase algorithms, suspend/resume capability, and dual protection modes (Persistent Lock Bits and Password-based Advanced Sector Protection).
The 56-pin TSOP package supports byte/word configuration via BYTE# input, while VIO voltage independently sets I/O logic levels - decoupling interface signaling from core VCC supply. The RY/BY# output provides real-time status of active programming or erasing operations, and RESET# enables hardware-initiated recovery to read mode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 256 Mbit (32 MB), organized as 256 × 128 Kbyte uniform sectors - enables modular firmware partitioning and OTA update resilience. |
| Access Time | 25 ns page access / 100 ns random access (regulated VCC = 3.0–3.6 V) - meets timing requirements for 10 MHz+ CPU bus interfaces. |
| Write Buffer | 32-word (64-byte) buffer - reduces multi-word programming overhead by >75% vs. single-word writes. |
| Erase Endurance | 100,000 cycles per sector - supports frequent field firmware reprogramming in industrial gateways and PLCs. |
| Data Retention | 20 years at +85°C - ensures long-term reliability in unattended embedded deployments. |

Pinout & Package
Package: 56-pin Thin Small Outline Package (TSOP), standard pinout (TSO56), lead-free (Pb-free), industrial temperature grade.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A23–A0 | Address Inputs | 24-bit address bus (A23–A0) selects 128 Kbyte sector and internal word location; A23 = MSB for 256 Mbit density. |
| DQ15–DQ0 | Data I/O (Word Mode) | 16-bit bidirectional data bus; operates in word mode when BYTE# = VIH - matches 16-bit microcontroller data paths. |
| DQ15/A-1 | Multi-function Pin | In word mode: DQ15; in byte mode (BYTE# = VIL): A-1 (LSB address) - enables flexible 8/16-bit system integration. |
| CE#, OE#, WE# | Chip/Output/Write Enable | Standard asynchronous SRAM-like control signals - allows drop-in replacement in existing memory-mapped designs. |
| WP#/ACC | Write Protect / Acceleration | At VIL: locks top/bottom sector; at VHH: enables unlock bypass mode for accelerated programming during production test. |
| RY/BY# | Ready/Busy Output | Active-low open-drain signal indicates ongoing program/erase - eliminates need for polling or timer-based delay loops. |
| RESET# | Hardware Reset | Asynchronous active-low input forces device into read array mode - critical for safe recovery after power-up or fault conditions. |
Key Features
| Feature | Design Value |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S29GL256S10TFI010 | Successor generation using 65 nm Eclipse MirrorBit process; 15% lower active current (42 mA vs. 50 mA), same 256 Mbit density and TSOP-56 package. | Higher energy efficiency in battery-backed or thermally constrained designs; identical command set and pinout. | Select when optimizing for power-sensitive portable or sealed industrial enclosures. |
| MX29GL256FHT2I-90G | Macronix 256 Mbit 3 V NOR Flash; 90 ns access time, 64-ball BGA only (no TSOP option); lacks VersatileI/O and Secured Silicon Sector. | Requires PCB redesign for BGA; no factory-programmable serial ID or VIO flexibility - limits secure boot and mixed-voltage use. | Select only if BGA footprint is mandatory and security/VIO features are unnecessary. |
Compared with S29GL256P10TFI010, the S29GL256S10TFI010 offers measurable power reduction without sacrificing compatibility, while the MX29GL256FHT2I-90G trades feature depth for cost and density parity - making the original optimal for industrial TSOP-based designs needing security and interface flexibility.

FAQ
What is the function of the VIO pin on S29GL256P10TFI010?
The VIO pin sets the voltage threshold for all input and output logic levels (address, control, and DQ signals), independent of VCC. With VIO ranging from 1.65 V to VCC, it enables direct interfacing with 1.8 V, 2.5 V, or 3.3 V host processors without external level shifters - a key enabler for mixed-voltage system designs.
Does S29GL256P10TFI010 support hardware write protection of specific sectors?
Yes. The WP#/ACC pin provides hardware-level protection: when held at VIL, it permanently locks either the highest or lowest 128 Kbyte sector (configurable at order time as "01" or "02"). This protection remains active even after power cycles and cannot be overridden by software commands - ensuring critical boot code or calibration data remains immutable.
Can S29GL256P10TFI010 be used in byte-mode configurations?
Yes. When the BYTE# pin is driven low (VIL), the device enters byte mode: DQ0–DQ7 become active data lines, and DQ15/A-1 functions as the LSB address input (A-1). This allows seamless integration with 8-bit microcontrollers or legacy systems requiring narrow data bus widths without external multiplexing.
What is the purpose of the Secured Silicon Sector in this Flash device?
The Secured Silicon Sector is a dedicated 256-byte memory region that can be factory-programmed with a unique 16-byte Electronic Serial Number and permanently locked. Once secured, its contents cannot be erased or rewritten - providing cryptographically verifiable device identity for secure boot, licensing, and anti-counterfeiting in regulated applications like medical and industrial control systems.
