Product details

Overview

S29GL032N90DFI023 from Infineon Technologies (formerly Cypress) is a 32-Mbit, 16-bit-wide single-power-supply MirrorBit Flash memory IC organized as 2,097,152 words (4,194,304 bytes), featuring 90 ns access time, 25 ns page read time, and uniform sector architecture with sixty-four 32 Kword (64 KB) sectors. It operates from a single 3.0 V supply (2.7–3.6 V), supports JEDEC-compliant command set, and is used for firmware storage in industrial control systems requiring reliable nonvolatile code retention.

For engineers reviewing the S29GL032N90DFI023 datasheet, S29GL032N90DFI023 pinout, S29GL032N90DFI023 application, or S29GL032N90DFI023 equivalent, key selection criteria include uniform sector erase capability, Secured Silicon Sector with factory-programmed 128-word ESN, CFI compliance for host auto-configuration, and hardware write protection via WP#/ACC input.

Technical Context

This device implements a command-register-based interface with asynchronous parallel bus operation, supporting both word and byte configuration via BYTE# input. Its internal state machine handles erase, program, and suspend/resume operations without external timing control.

The MirrorBit architecture uses hot-hole assisted erase and hot-electron injection programming across 110 nm process technology. Sector-level erasure enables selective reprogramming while preserving data in unaffected sectors, and the Secured Silicon Sector provides permanent 256-byte protected storage accessible only through defined command sequences.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory Density	32 Mbit (2,097,152 × 16-bit words); sufficient for boot code and firmware images in resource-constrained embedded controllers.
Access Time	90 ns at VCC = 2.7–3.6 V; enables direct execution from flash (XIP) in real-time microcontroller applications.
Page Read Time	25 ns; reduces latency during burst reads of instruction blocks or configuration tables.
Erase Endurance	100,000 cycles per sector; supports field firmware updates over product lifetime in industrial gateways.
Data Retention	20 years at 125°C; validated for automotive under-hood and industrial high-temperature environments.
Supply Voltage	VCC = 2.7–3.6 V, VIO = 1.65–3.6 V; allows flexible I/O voltage scaling independent of core supply.
Standby Current	1 µA typical; minimizes power draw in always-on monitoring devices during sleep mode.

Pinout & Package

Package: 48-pin TSOP (Standard Thin Small Outline Package), 12 × 20 mm body, surface-mount, lead-free RoHS-compliant.

Pin/Terminal	Circuit Role	Design Meaning
A0–A20	Address Inputs	21-bit address bus supporting full 32 Mbit addressing; A-1 (DQ15) multiplexed as MSB in word mode.
DQ0–DQ15	Data/Address Bus	16-bit bidirectional data bus; DQ15 functions as A-1 (MSB) in word mode, enabling 2,097,152-word addressing.
CE#, OE#, WE#	Chip/Output/Write Enable	Independent active-low controls allow interleaved read/write operations and partial memory mapping in multi-chip systems.
WP#/ACC	Write Protect / Accelerated Program	Hardware lock for first/last sector; applies high-voltage acceleration during factory programming to reduce cycle time.
RY/BY#	Ready/Busy Output	Open-drain status signal indicating active erase/program; eliminates need for polling in interrupt-driven firmware.
RESET#	Hardware Reset Input	Asynchronous reset terminates ongoing operations and restores device to known state-critical for safe boot recovery.
BYTE#	Bus Width Select	Configures 16-bit or 8-bit data interface; enables compatibility with legacy 8-bit microcontrollers without external glue logic.

Key Features

Feature	Design Value
Secured Silicon Sector	128-word (256-byte) factory-lockable region with unique 8-word electronic serial number-enables secure device identity binding in IoT edge nodes.
Program/Erase Suspend	Allows host to pause programming or erasing to service interrupts or read other sectors-essential for deterministic real-time response in motor control firmware.
CFI Compliance	Enables automatic detection and configuration by host BIOS or bootloader without hard-coded timing or geometry parameters.
Advanced Sector Protection	Combines persistent lock bits and password-based sector locking-prevents unauthorized firmware modification in medical diagnostic equipment.
VIO Voltage Independence	VIO range 1.65–3.6 V decouples I/O voltage from VCC, simplifying integration with mixed-voltage SoCs and FPGAs.

Equivalent & Alternatives

The following parts are listed as comparable options for similar Flash memory applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
S29GL032N90TFI020	Same die, 48-ball fine-pitch BGA package (VBK048); no TSOP pins; 110 ns access at VIO = 1.65–3.6 V.	Used where board space is constrained and PCB routing favors BGA over gull-wing leads.	Select when footprint density outweighs hand-solderability and test accessibility requirements.
MX29GL320EHT2I-90G	32 Mbit, 90 ns, but uses 1.8 V core + 3.3 V I/O; lacks Secured Silicon Sector and CFI support.	Targeted at cost-sensitive consumer electronics where security and host auto-configuration are not required.	Choose only if VIO independence, ESN, and bootloader interoperability are not design requirements.

Compared with S29GL032N90DFI023, the TSOP-packaged alternative offers identical functionality and timing in a through-hole-compatible form factor, while the Macronix part sacrifices security and configurability for lower unit cost in non-critical applications.

FAQ

Is S29GL032N90DFI023 compatible with legacy 3.3 V-only systems?

Yes. The device operates with VCC = 2.7–3.6 V and VIO = 1.65–3.6 V, allowing direct interface to 3.3 V microcontrollers without level shifters. Its JEDEC software compatibility ensures drop-in replacement for earlier single-supply Flash parts in existing designs.

How does the Secured Silicon Sector differ from standard sector protection?

The Secured Silicon Sector is a dedicated 256-byte region programmed and locked at the factory or by the user, containing an immutable 16-byte electronic serial number. Unlike standard sector protection, it cannot be erased or rewritten once locked-even with full command access-and serves as a hardware root of trust.

Can this Flash be used for Execute-in-Place (XIP) operation?

Yes. With 90 ns access time and asynchronous parallel interface, the device supports XIP directly from the MCU's memory-mapped address space. Verified timing margins at VCC = 3.0 V ±0.3 V ensure reliable instruction fetch under worst-case voltage and temperature conditions.

What happens during power loss while programming or erasing?

An internal low-VCC detector disables all write operations when supply drops below ~2.5 V, preventing partial writes or sector corruption. The device retains its last valid state, and incomplete operations must be reinitiated after power restoration and reset.
