Product details

Overview

S29GL128P10TFI023 from Cypress Semiconductor is a 128 Mbit (16 MB), single-supply 3.0 V page-mode Flash memory IC fabricated on 90 nm MirrorBit process technology, featuring 25 ns page access time, 90 ns random access time, uniform 64 Kword sectors (128 total), and 100,000 erase cycles per sector - deployed in industrial embedded systems for firmware storage and boot code execution.

For engineers reviewing the S29GL128P10TFI023 datasheet, S29GL128P10TFI023 pinout, S29GL128P10TFI023 application, or S29GL128P10TFI023 equivalent, key selection criteria include VersatileI/O™ voltage flexibility (VIO = 1.65–VCC), write buffer programming efficiency (64-byte burst), secured silicon sector with electronic serial number, and TSOP-56 industrial-temperature packaging.

Technical Context

This device implements a synchronous/non-volatile memory architecture with dedicated command register, state control logic, and embedded erase/program algorithms. It supports CFI-compliant identification, multiple protection modes (persistent lock bits and password), and hardware reset (RESET#) with Ready/Busy# status signaling.

The memory array is organized into 128 uniform sectors of 64 Kwords (128 Kbytes) each, with byte/word configuration selectable via BYTE# input. VersatileI/O™ decouples I/O voltage (VIO) from core supply (VCC), enabling interoperability with mixed-voltage host systems while maintaining full 2.7–3.6 V operating range.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory Density	128 Mbit (16 MB) - supports full boot image storage for mid-tier microcontrollers.
Page Access Time	25 ns - enables high-speed sequential instruction fetch during boot or firmware update.
Random Access Time	90 ns (Regulated VCC) - meets timing requirements for direct execution from flash in XIP configurations.
Write Buffer Size	64 bytes - reduces effective programming time by batching up to 32 words per command sequence.
Sector Erase Time	0.5 s per 64 Kword sector - predictable, bounded erase latency for field firmware updates.
Data Retention	20 years typical - ensures long-term reliability in unattended industrial deployments.
Endurance	100,000 erase cycles per sector - supports frequent over-the-air (OTA) update cycles in edge devices.

Equivalent & Alternatives

The following parts are listed as comparable options for similar page-mode parallel Flash memory applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
S29GL128S10TFI020	Successor generation using 65 nm Eclipse process; 110 ns random access; lower standby current (100 nA vs. 1 µA).	Requires updated timing margins and may lack identical CFI query responses; not drop-in compatible due to command set extensions.	Select when lowest power and newer process node are prioritized over legacy design reuse.
MX29GL128FHT2I-90G	Macronix equivalent; same 128 Mbit density, TSOP-56, 90 ns speed grade; no VersatileI/O™ or secured silicon sector.	Lacks VIO flexibility and hardware-based serial number - requires external security layer for authentication.	Select when cost sensitivity outweighs advanced protection features and mixed-voltage interface needs.

Compared with S29GL128S10TFI020, this part offers proven maturity and broader ecosystem support; compared with MX29GL128FHT2I-90G, it delivers integrated security and voltage-flexible interfacing at modest premium - making it optimal for industrial firmware integrity and long-lifecycle designs.

FAQ

What is the function of the VIO pin on S29GL128P10TFI023?

The VIO pin sets the voltage level for all input thresholds and output drive levels, independent of VCC. It accepts 1.65 V to VCC, allowing the device to interface directly with 1.8 V or 3.3 V host processors without level shifters - a key enabler for mixed-voltage system designs.

Does S29GL128P10TFI023 support hardware write protection for specific sectors?

Yes - the WP#/ACC pin provides hardware-level protection for the highest or lowest 64 Kword sector depending on model configuration (R1/R2/V1/V2). When pulled low, it disables program/erase in those sectors regardless of software protection settings, offering fail-safe boot-sector safeguarding.

How does the Secured Silicon Sector enhance device authentication?

The Secured Silicon Sector contains a 128-byte region with an 8-word (16-byte) factory-programmable electronic serial number. Once locked, this region becomes permanently read-only and tamper-resistant - enabling unique device identification and cryptographic key binding in secure boot implementations.

Can S29GL128P10TFI023 be used in systems requiring zero-power data retention during extended storage?

Yes - the device guarantees 20 years of data retention at +85°C and indefinite retention at lower temperatures. Its 90 nm MirrorBit architecture minimizes charge leakage, and the 1 µA standby current ensures minimal battery drain in always-on backup power scenarios.
