Product details

Overview

S29GL032N90FFI040 from Infineon Technologies (formerly Cypress) is a 32-Mbit, 16-bit-wide single-supply MirrorBit Flash memory 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 boot code storage and firmware updates in industrial control systems.

For engineers reviewing the S29GL032N90FFI040 datasheet, S29GL032N90FFI040 pinout, S29GL032N90FFI040 application, or S29GL032N90FFI040 equivalent, key selection criteria include sector erase flexibility, Secured Silicon Sector with factory-programmed 128-word ESN, CFI compliance for host auto-configuration, and hardware reset (RESET#) and ready/busy (RY/BY#) signaling for embedded system integration.

Technical Context

This device implements a NOR Flash architecture with hot-electron injection programming and hot-hole assisted sector erase. Its command-set compatibility with JEDEC JESD21-C ensures interoperability with legacy and new host controllers without firmware modification.

The 110 nm MirrorBit process enables high-density storage with 100,000 erase cycles per sector and 20-year data retention. The VIO input (1.65–3.6 V) independently controls I/O voltage levels, decoupling interface logic from core VCC (2.7–3.6 V), enabling mixed-voltage system interfacing.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory Density	32 Mbit (2,097,152 × 16-bit words); sufficient for full bootloader + application firmware in resource-constrained microcontrollers.
Access Time	90 ns at VCC = 2.7–3.6 V; enables direct execution (XIP) from flash in real-time control loops without wait states.
Page Read Time	25 ns; supports burst reads of up to 8 words (16 bytes) for efficient instruction fetch in pipelined architectures.
Erase Endurance	100,000 cycles per sector; validated for field firmware update cycles over 10+ years in industrial gateways.
Data Retention	20 years at 125°C; meets extended lifetime requirements for automotive under-hood and industrial motor drive applications.
Supply Voltage	VCC = 2.7–3.6 V, VIO = 1.65–3.6 V; allows direct connection to 3.3 V MCU I/O while supporting 1.8 V logic interfaces via VIO pin.
Standby Current	1 µA typical; reduces power budget in battery-backed or energy-harvesting edge sensor nodes.

Pinout & Package

Package: 48-pin TSOP (Type I, standard thin small outline package), 12 × 20 mm body, 0.5 mm pitch, lead-free and RoHS compliant.

Pin/Terminal	Circuit Role	Design Meaning
A0–A21	Address Inputs	22-bit address bus supporting full 32 Mbit addressing; A-1 (DQ15/A-1) multiplexed for byte/word mode selection.
DQ0–DQ15	Data/Address Bus	16-bit bidirectional data bus; DQ15 functions as A-1 in byte mode when BYTE# = low.
CE#, OE#, WE#	Chip/Output/Write Enable	Independent three-control gating enables concurrent memory access arbitration and eliminates bus contention during multi-device operation.
RY/BY#	Ready/Busy Output	Open-drain active-low signal indicating internal program/erase completion; eliminates need for polling in interrupt-driven firmware.
RESET#	Hardware Reset Input	Asynchronous active-low reset that terminates ongoing operations and restores device to known state; synchronizes with system power-on reset.
WP#/ACC	Write Protect / Accelerated Program	Low-active write protect for first/last sector; high-voltage mode (when driven > VCC) reduces programming time by ~30% in production test.
BYTE#	Bus Width Select	Active-low input selecting 16-bit (BYTE# = high) or dual 8-bit (BYTE# = low) data interface for compatibility with 8-bit microcontrollers.

Key Features

Feature	Design Value
Secured Silicon Sector	128-word (256-byte) factory-locked region with 8-word electronic serial number; provides immutable device identity for secure boot and anti-cloning.
Program/Erase Suspend	Allows host to pause programming or erasing in one sector to read/write another sector; enables real-time firmware patching without halting system operation.
CFI Compliance	Standardized query structure enables automatic detection of device geometry, timing, and protection features by host BIOS or bootloader-no hardcoded parameters required.
Unlock Bypass Mode	Reduces multi-word programming overhead from four to two write cycles per word; cuts firmware update time by ~40% in high-volume manufacturing.
Persistent Sector Protection	Non-volatile lock bits prevent accidental or malicious reprogramming of critical boot sectors-even after power cycle-without dedicated 12 V supply.

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 TSOP pins; 1.65–3.6 V VIO range identical.	Targeted for space-constrained PCBs where 48-pin TSOP footprint is prohibitive; requires BGA reflow and X-ray inspection.	Select for high-density consumer electronics where board area is premium and thermal profile supports BGA mounting.
MX29GL320EHTI-90G	Micron 32 Mbit NOR Flash; 90 ns access, but uses 1.8/3.3 V dual supply (VCC/VIO separate pins); no Secured Silicon Sector.	Lacks factory-programmed ESN and persistent sector lock; relies on external security IC for secure boot.	Choose when cost sensitivity outweighs secure identity needs and existing design already supports dual-voltage I/O routing.

Compared with S29GL032N90FFI040, the BGA variant offers identical functionality in smaller form factor but higher assembly complexity, while the Micron alternative trades security and software compatibility for lower unit cost and dual-supply flexibility-making it suitable only where secure boot and JEDEC command consistency are not required.

FAQ

What is the function of the WP#/ACC pin on S29GL032N90FFI040?

The WP#/ACC pin serves dual roles: as WP# (Write Protect), it disables programming/erasing of the first or last sector when pulled low; as ACC (Accelerated Program), it accepts >VCC voltage (typically 4.5–5.5 V) to reduce programming time by ~30%. This dual functionality is selected automatically based on applied voltage level and does not require external switching circuitry.

Does S29GL032N90FFI040 support both 8-bit and 16-bit data bus widths?

Yes. When BYTE# is high, the device operates as a 16-bit wide memory (DQ0–DQ15 active). When BYTE# is low, it functions as two independent 8-bit buses: DQ0–DQ7 as lower byte and DQ8–DQ15 as upper byte. This mode is confirmed in the datasheet's "Word/Byte Configuration" section and supported across all operating voltages.

How is the Secured Silicon Sector protected and accessed?

The Secured Silicon Sector is a 128-word (256-byte) region pre-programmed at the factory with an 8-word electronic serial number. Access requires issuing the Enter Secured Silicon Sector command sequence (0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00). Once locked, no further writes or erases are possible-even with full VCC and command sequences-ensuring permanent device identity.

Can S29GL032N90FFI040 be used in systems with 1.8 V I/O interfaces?

Yes. By setting VIO = 1.65–3.6 V independently of VCC (2.7–3.6 V), the device supports 1.8 V logic-level signaling on DQ, CE#, OE#, WE#, and other control pins. This is verified in the "Enhanced VersatileI/O™ Control" section and confirmed in AC characteristics tables for VIO = 1.65–3.6 V operation.
