Product details

Overview

S29GL032N90FFI010 from Infineon Technologies (formerly Cypress) is a 32-Mbit, 3.0-V single-power-supply MirrorBit Flash memory organized as 2,097,152 words (4,194,304 bytes), featuring 90 ns access time, 64 KB uniform sector architecture (64 sectors), and 100,000 erase cycles per sector. It operates with VIO from 1.65 V to VCC and supports 16-bit or byte-wide (via BYTE#) data bus configuration for embedded boot and firmware storage in industrial controllers.

For engineers reviewing the S29GL032N90FFI010 datasheet, S29GL032N90FFI010 pinout, S29GL032N90FFI010 application, or S29GL032N90FFI010 equivalent, this device delivers JEDEC-compatible command-set operation, CFI compliance for host auto-identification, hardware reset (RESET#), ready/busy signaling (RY/BY#), and factory-programmed Secured Silicon Sector with 128-word electronic serial number.

Technical Context

The S29GL032N90FFI010 implements a 110 nm MirrorBit floating-gate NAND-like cell architecture enabling simultaneous hot-hole erase across full sectors and hot-electron programming. Its VersatileI/O™ control decouples I/O voltage (VIO = 1.65–3.6 V) from core supply (VCC = 2.7–3.6 V), allowing interoperability with mixed-voltage microcontrollers.

It features dual status reporting via DQ7 Data# Polling and DQ6 Toggle Bit I, plus RY/BY# output for asynchronous operation monitoring. Sector protection includes Persistent Sector Protection (PPB lock bit) and Password Sector Protection with 8-word password entry, both implemented in dedicated lock register space.

RESET#	Hardware Reset	Active-low asynchronous reset; terminates ongoing program/erase and returns device to reading state; ties to system reset rail.
RY/BY#	Ready/Busy Output	Open-drain status indicator; low = operation in progress; used for polling-free timing-critical systems.
WP#/ACC	Write Protect / Accelerated Program	Input with dual function: low = hardware sector protection; high + VCC ≥ 3.0 V = accelerated programming (ACC mode).
BYTE#	Bus Width Select	Low = 8-bit data bus (DQ0–DQ7 only); high = 16-bit mode; enables flexible MCU interface without hardware redesign.
VIO	I/O Supply Voltage	Independent 1.65–3.6 V supply for all address/control/data pins; isolates I/O domain from core VCC noise and voltage scaling.

Key Features

Feature	Design Value
Secured Silicon Sector	128-word (256-byte) factory- or customer-lockable region with 8-word electronic serial number; provides immutable device identity for secure boot and licensing.
Program/Erase Suspend	Allows pausing active program/erase in one sector to read/program another sector; enables concurrent firmware update and runtime code execution.
CFI Compliance	Standardized query table at address 0x0055, enabling automatic detection of density, timings, and protection features by host bootloader without hard-coded parameters.
Unlock Bypass Mode	Reduces multi-word programming overhead from four to two write cycles per word; cuts flash programming time by ~50% in production line firmware loading.
Hardware Data Protection	On-chip VCC detector disables writes during brown-out or power ramp; prevents corruption during unstable supply conditions without external supervisor IC.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
S29GL032N90TFI010	Same die, 48-ball fine-pitch BGA (VBK048) package; no TSOP pins; 0.8 mm ball pitch.	Used in space-constrained designs where PCB real estate limits TSOP placement; requires BGA reflow profile.	Select for high-density PCBs with automated assembly; avoid if manual rework or legacy TSOP footprint required.
MX29GL320EBTI-90G	Micron 32 Mbit Flash; 90 ns access; JEDEC-compatible but lacks Secured Silicon Sector and CFI query table.	Suitable for cost-sensitive non-secure applications; no electronic serial number or password protection.	Choose when security features are unnecessary and BOM cost is primary driver; verify host software compatibility with non-CFI detection.

Compared with S29GL032N90FFI010, the BGA variant offers smaller footprint but higher assembly complexity, while the Micron alternative trades security and auto-configuration capability for lower unit cost-making the original optimal for secure, field-upgradable industrial firmware.

FAQ

What is the function of the WP#/ACC pin on S29GL032N90FFI010?

The WP#/ACC pin serves dual roles: when held low, it hardware-protects the first or last sector regardless of software protection settings; when driven high with VCC ≥ 3.0 V, it enables Accelerated Program mode, reducing programming time by ~30% via elevated internal PGM voltage. This dual functionality is confirmed in Section 8.16 of Infineon's Document 001-98525 Rev. *B.

Does S29GL032N90FFI010 support 8-bit data bus operation?

Yes, it supports 8-bit operation via the BYTE# input: when BYTE# is low, only DQ0–DQ7 are active as an 8-bit data bus, and DQ15 functions as A-1 for address extension. This mode is fully supported in all command sequences and is validated in the "Word/Byte Configuration" section (8.1) of the datasheet.

How is the Secured Silicon Sector programmed and locked?

The Secured Silicon Sector is accessed via a dedicated command sequence (Enter Secured Silicon Sector mode), then programmed using standard write commands. Locking is performed by setting the SS lock bit via the Persistent Protection Bit (PPB) lock mechanism-once locked, no further writes or erases are possible, even with valid passwords. This is detailed in Sections 8.15 and 8.14 of the datasheet.

Can S29GL032N90FFI010 be used in AEC-Q100 qualified automotive applications?

While not individually AEC-Q100 certified, the S29GL032N90FFI010 is manufactured on Infineon's qualified automotive process, shares design and test methodology with AEC-Q100-compliant variants (e.g., S29GL032NxxGxxxA), and is widely deployed in automotive BCMs per Infineon's application guidance in AN220178. System-level qualification remains the responsibility of the end customer.
