Product details

Overview

S29GL256N10FAI012 from Cypress Semiconductor is a 256 Mbit (33,554,432-byte), 16-bit wide, single-supply 3.0 V Page Flash memory manufactured on 110 nm MirrorBit process technology. It features 256 × 128 Kbyte sectors, 90 ns access time at regulated 3.0–3.6 V VCC/VIO, 1 µA standby current, and JEDEC-compliant command set for embedded boot code storage in industrial control systems.

For engineers reviewing the S29GL256N10FAI012 datasheet, S29GL256N10FAI012 pinout, S29GL256N10FAI012 application, or S29GL256N10FAI012 equivalent, key selection criteria include sector erase flexibility, Secured Silicon Sector with 128-word ESN, Enhanced VersatileI/O™ voltage adaptability (1.65–3.6 V), and hardware reset (RESET#) support for reliable system boot recovery.

Technical Context

This device implements a parallel NOR flash architecture with separate CE#, OE#, and WE# controls, enabling true random-access read and page-based program/sector-erase operations. Its command-set compatibility with JEDEC JESD21-C ensures interoperability with legacy host controllers without firmware modification.

The 110 nm MirrorBit cell structure enables hot-hole erase and hot-electron programming, delivering 100,000 erase cycles per sector and 20-year data retention. The VIO pin dynamically sets input/output voltage thresholds, allowing seamless integration into both 1.8 V and 3.0 V I/O domains while maintaining full 3.0 V core operation.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory Density	256 Mbit (16,777,216 words × 16 bits), organized as 256 × 128 Kbyte sectors - supports modular firmware partitioning and field-upgradable code regions.
Access Time	90 ns (VCC/VIO = 3.0–3.6 V, regulated) - enables direct execution of boot code from flash on microcontrollers with ≤11 MHz bus timing.
Page Read Buffer	8-word / 16-byte - reduces sequential read latency by prefetching adjacent data during burst accesses.
Write Buffer Size	16-word / 32-byte - cuts multi-word programming time by batching writes and minimizing command overhead.
Standby Current	1 µA typical - meets ultra-low-power requirements for battery-backed industrial monitoring nodes during sleep mode.
Erase Endurance	100,000 cycles per sector - supports frequent configuration updates in programmable logic controllers without wear leveling.
Data Retention	20 years typical - ensures long-term reliability for firmware stored in unattended infrastructure equipment.

Pinout & Package

Package: 56-pin TSOP (Standard Thin Small Outline Package), RoHS-compliant, lead-free, surface-mount.

Pin/Terminal	Circuit Role	Design Meaning
A0–A23	Address Inputs	24-bit address bus supporting full 256 Mbit addressing; A23 is valid (unlike S29GL128N).
DQ0–DQ15	Data I/O	16-bit bidirectional data bus; BYTE# pin enables 8-bit mode for legacy 8-bit microcontroller interfaces.
CE#	Chip Enable	Active-low chip select; enables device decoding in multi-chip memory maps with independent chip selection.
OE#	Output Enable	Active-low output gate; allows shared data bus operation with other peripherals without tristate conflicts.
WE#	Write Enable	Active-low write strobe; latches addresses and data for command execution and programming cycles.
WP#/ACC	Write Protect / Accelerated Program	Low = hardware sector protection (first/last sector); high = accelerated programming via elevated internal current.
RY/BY#	Ready/Busy Output	Open-drain active-low status signal indicating ongoing program/erase; eliminates need for polling DQ lines.
RESET#	Hardware Reset	Active-low asynchronous reset; terminates any operation and restores device to known state for safe boot recovery.
VIO	I/O Voltage Reference	Defines logic threshold for all address/control/data pins (1.65–3.6 V); decouples I/O domain from core VCC.

Key Features

Feature	Design Value
Secured Silicon Sector	128-word (256-byte) factory- or customer-lockable region with 8-word electronic serial number - enables secure device identification and immutable bootloader storage.
Program/Erase Suspend	Pause active program/erase in one sector to read/program another - supports real-time interrupt handling during firmware updates without data corruption.
Password Sector Protection	64-bit user-defined password required to unlock protected sectors - prevents unauthorized firmware modification in deployed field devices.
CFI Compliance	Common Flash Interface compliant - allows automatic detection and configuration by BIOS/bootloader without hard-coded timing or geometry tables.
Enhanced VersatileI/O™	VIO pin configures all I/O thresholds dynamically - eliminates level-shifters when interfacing with mixed-voltage SoCs (e.g., 1.8 V CPU + 3.0 V flash).

Equivalent & Alternatives

The following parts are listed as comparable options for similar parallel NOR flash memory applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
S29GL256S10TFI010	Successor device in same family; 65 nm MirrorBit process, 90 ns access, 56-pin TSOP, but adds dual-plane architecture and faster erase times (typ. 0.5 s/sector vs. 0.8 s).	Designed for new designs requiring longer product lifecycle support and improved endurance (1M erase cycles).	Select for new designs needing extended availability, higher endurance, and lower power (0.5 µA standby).
MX29GL256FHI-90G	Macronix pin-compatible 256 Mbit NOR flash; 90 ns access, 56-pin TSOP, but lacks Secured Silicon Sector and Password Protection.	Cost-sensitive industrial applications where security features are not mandated and CFI support is sufficient.	Choose when budget constraints outweigh need for ESN, password lock, or erase suspend functionality.

Compared with S29GL256N10FAI012, the S29GL256S10TFI010 offers superior longevity and lower power but requires minor timing adjustments; the MX29GL256FHI-90G provides drop-in cost savings at the expense of security and advanced suspend capabilities.

FAQ

Is S29GL256N10FAI012 still in production?

No - Cypress officially retired the S29GL-N family and does not recommend it for new designs. However, Aetrix Electronics maintains limited legacy inventory with full traceability and supports existing production programs through lifecycle coordination and last-time-buy planning.

What package type does S29GL256N10FAI012 use?

S29GL256N10FAI012 uses a 56-pin Standard Thin Small Outline Package (TSOP), with dimensions compliant to TS056 mechanical specifications. It is RoHS-compliant, lead-free, and rated for industrial temperature range (–40°C to +85°C).

Does this device support 1.8 V I/O interfacing?

Yes - the Enhanced VersatileI/O™ (VIO) feature allows full 1.8 V I/O operation when VIO = 1.65–1.95 V, while maintaining 3.0 V core functionality. All address, control, and data pins conform to 1.8 V logic thresholds under this condition.

Can the Secured Silicon Sector be erased or rewritten after locking?

No - once the Secured Silicon Sector is locked (via command sequence), it becomes permanently read-only. The 8-word electronic serial number remains accessible, but no further programming or erasure is possible, even with power cycle or RESET# assertion.
