Product details

Overview

S29GL032N90TAI030 from Infineon Technologies (formerly Cypress) is a 32 Mbit (4,194,304-byte), 16-bit-wide single-supply MirrorBit Flash memory with 90 ns access time, uniform sector architecture (64 × 64 KB sectors), and Secured Silicon Sector for factory-programmed electronic serial number. It operates from 2.7–3.6 V V_CC and 1.65–3.6 V V_IO, supporting boot code storage in industrial controllers and firmware retention in network edge devices.

For engineers reviewing the S29GL032N90TAI030 datasheet, S29GL032N90TAI030 pinout, S29GL032N90TAI030 application, or S29GL032N90TAI030 equivalent, key selection criteria include JEDEC-compliant command set, 100,000 erase cycles per sector, CFI interface support, hardware reset (RESET#) and ready/busy (RY/BY#) signaling, and 48-pin TSOP packaging with BYTE# configurable 8/16-bit data bus operation.

Technical Context

This device implements a 110 nm MirrorBit floating-gate NOR architecture with hot-hole assisted erase and hot-electron injection programming. It features separate CE#, WE#, and OE# controls, supports both word and byte read/write via BYTE# input, and uses DQ7 polling and DQ6 toggle bits for operation status feedback.

The Secured Silicon Sector provides 256-byte factory- or customer-lockable space with 8-word ESN; Advanced Sector Protection includes Persistent and Password modes. Erase Suspend/Resume and Program Suspend/Resume enable concurrent sector access during background operations.

Key Specifications

Memory Size	32 Mbit (4,194,304 bytes), organized as 2,097,152 × 16-bit words
Access Time	90 ns max at V_CC = 2.7–3.6 V - enables direct execution from flash in real-time microcontroller systems
Erase Endurance	100,000 cycles typical per sector - supports field firmware updates over product lifetime
Data Retention	20 years typical - ensures long-term reliability in unpowered storage applications
Supply Voltage	V_CC: 2.7–3.6 V; V_IO: 1.65–3.6 V - allows interoperability with mixed-voltage SoC interfaces
Page Read Time	25 ns - reduces latency during burst instruction fetch sequences
Write Buffer Size	16-word (32-byte) buffer - cuts multi-word programming time by minimizing command overhead

Pinout & Package

Package: 48-pin TSOP (Standard Thin Small Outline Package), lead pitch 0.5 mm, body size 12 × 20 mm.

Pin/Terminal	Circuit Role	Design Meaning
A0–A21	Address Inputs	22-bit address bus supporting full 4 MB addressing; A-1 used for DQ15/A-1 multiplexing
DQ0–DQ15	Data I/O	16-bit bidirectional data bus; DQ15 functions as A-1 during address phase
CE#	Chip Enable	Active-low chip select enabling device operation; required for all read/write/erase commands
WE#	Write Enable	Active-low control for write and command latch operations; defines write cycle timing
OE#	Output Enable	Active-low control for output buffer activation; enables read data to drive bus
BYTE#	Bus Width Select	Configures 16-bit (high) or 8-bit (low) data bus mode; critical for legacy 8-bit host compatibility
WP#/ACC	Write Protect / Accelerated Program	Low = hardware sector protection; high voltage = accelerated programming for production throughput
RESET#	Hardware Reset	Active-low asynchronous reset terminating all operations and returning device to read mode
RY/BY#	Ready/Busy Output	Open-drain active-low signal indicating internal operation progress; used for polling-free timing control
V_IO	I/O Supply	Independent voltage reference for all input thresholds and output levels; decouples I/O logic from core V_CC

Key Features

Feature	Design Value
Secured Silicon Sector	256-byte factory- or customer-lockable region with 16-byte ESN - enables secure device identity binding
CFI Compliance	JEDEC-standard Common Flash Interface - allows automatic detection and configuration by host BIOS/bootloader
Unlock Bypass Mode	Reduces multi-word programming to two write cycles instead of four - improves system-level firmware update speed
Program/Erase Suspend	Pause ongoing program/erase to read/program other sectors - enables real-time interrupt handling during flash updates
Hardware Data Protection	Low-V_CC detector inhibits writes during power ramp-up/down - prevents corruption during brown-out conditions

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
S29GL032N90TFI020	Same die, 48-ball fine-pitch BGA (VBK048) package; no BYTE# pin; V_IO range 1.65–3.6 V identical	Used where board space constraints require BGA mounting and 8-bit bus not needed	Select when footprint density > signal flexibility; requires rework-capable assembly process
MX29GL32EHXFI-90G	32 Mbit Macronix device; 90 ns access; 48-pin TSOP; supports CFI but lacks Secured Silicon Sector and Password Protection	Suitable for cost-sensitive consumer applications where secure identity and sector-level password lock are unnecessary	Choose for price-driven designs without security or long-life field update requirements

Compared with S29GL032N90TFI020, this TSOP variant offers easier prototyping and debug visibility; versus MX29GL32EHXFI-90G, it delivers certified secure identity and robust sector protection essential for industrial and medical firmware integrity.

FAQ

What is the function of the BYTE# pin on S29GL032N90TAI030?

The BYTE# pin selects between 16-bit and 8-bit data bus operation: when high, DQ0–DQ15 function as a full 16-bit bus; when low, only DQ0–DQ7 are active for 8-bit transfers while DQ8–DQ15 are tri-stated. This enables backward compatibility with legacy 8-bit microcontrollers without external bus transceivers.

Does S29GL032N90TAI030 support in-system programming?

Yes - it supports full in-system programming via standard microprocessor write timing and JEDEC command sequences. No external high-voltage programmer is required; all program and erase operations are initiated through software commands written to specific address locations, with status monitored via DQ7 polling or RY/BY#.

How is the Secured Silicon Sector protected from accidental overwrite?

The Secured Silicon Sector is protected by permanent fuse-based locking: once the 128-word region is programmed and locked (via command sequence), no further writes or erases are possible - even with VPP applied or during bulk erase. The lock state is irreversible and survives power cycles, ensuring ESN integrity across device lifetime.

Can S29GL032N90TAI030 be used with a 1.8 V I/O interface?

No - V_IO must be within 1.65–3.6 V, but operation at 1.8 V is not characterized or guaranteed. At 1.8 V, input thresholds and output drive strength fall outside specification; reliable interfacing requires V_IO ≥ 2.3 V per AC characteristics table in datasheet Rev. *B, page 61.
