Product details

Overview

S29GL032N90TFI030 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- or customer-programmed 256-byte 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 control firmware.

For engineers reviewing the S29GL032N90TFI030 datasheet, S29GL032N90TFI030 pinout, S29GL032N90TFI030 application, or S29GL032N90TFI030 equivalent, key selection criteria include JEDEC-compliant command set, 100,000 erase cycles per sector, CFI compliance for host auto-configuration, and hardware write protection via WP#/ACC pin.

Technical Context

This device implements a 110 nm MirrorBit floating-gate NAND-like cell architecture enabling single-power 3.0 V operation with hot-electron programming and hot-hole assisted erase. It supports both uniform and boot-sector configurations, though S29GL032N90TFI030 is specifically a uniform-sector model with 64 identical 64 KB sectors.

It features VersatileI/O™ control where all input thresholds and output drive levels are referenced to V_IO, not V_CC, allowing mixed-voltage system interfacing. Status reporting uses DQ7 data# polling and DQ6 toggle bits, with RY/BY# active-low open-drain output for hardware-ready signaling.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory density	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 - defines minimum clock period for synchronous read in microcontroller interfaces
Page read time	25 ns - enables burst reads of up to 8 words (16 bytes) without address re-latching
Erase endurance	100,000 cycles per sector - supports field firmware updates over 10+ years in deployed industrial controllers
Data retention	20 years at 125°C - validated for automotive under-hood and industrial high-temp environments
Supply voltage range	V_CC: 2.7–3.6 V; V_IO: 1.65–3.6 V - allows direct interface to 1.8 V or 3.3 V logic without level shifters
Standby current	1 µA typical - reduces power in always-on embedded systems during idle states

Pinout & Package

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

Pin/Terminal	Circuit Role	Design Meaning
A0–A21	Address inputs	22-bit address bus; A21 selects upper 16 MB segment in 32 MB space; A-1 (DQ15) used as MSB in byte mode
DQ0–DQ15	Data I/O bidirectional bus	16-bit parallel interface; DQ15 doubles as A-1 in BYTE#-enabled 8-bit mode
CE#	Chip enable (active low)	Primary chip select; device enters standby when CE# high, independent of OE#/WE# state
OE#	Output enable (active low)	Controls data bus drivers only; read operations require CE# and OE# both low
WE#	Write enable (active low)	Controls latching of addresses/data during command sequences and programming/erase cycles
WP#/ACC	Write protect / accelerated program input	Low = hardware lock of first/last sector; high + 5.5 V = accelerated programming for production throughput
RY/BY#	Ready/Busy output (open-drain)	Active-low signal indicating internal program/erase completion; requires external pull-up
RESET#	Hardware reset (active low)	Aborts ongoing operation and returns device to reading state; tied to system reset for boot recovery
BYTE#	Bus width select	Low = 16-bit mode; high = 8-bit mode using DQ0–DQ7 only; enables compatibility with 8-bit microcontrollers

Key Features

Feature	Design Value
Secured Silicon Sector	256-byte factory- or user-lockable region with 16-byte ESN - provides immutable device identity for secure boot and licensing
Advanced Sector Protection	Persistent and Password-based locking - prevents accidental or unauthorized firmware overwrite without hardware reset or password entry
Program/Erase Suspend & Resume	Pause active programming/erasing to service interrupts or read other sectors - essential for real-time OS integration
CFI compliance	Standardized query table at address 0x55 × 0x55 - enables automatic detection and configuration by bootloader without hard-coded parameters
Unlock Bypass Program mode	Two-cycle instead of four-cycle command sequence - cuts multi-word programming overhead by ~50% in firmware update routines

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-pin TSOP but with 110 ns access time (V_IO = 1.65–3.6 V); otherwise identical pinout and command set	Lower performance grade suited for cost-sensitive, non-real-time applications where >90 ns latency is acceptable	Select when system clock rate permits longer read cycles and BOM cost reduction is prioritized over worst-case timing margin
MX29GL32EHXFI-90G	Macleod Semiconductor 32 Mbit Flash; 90 ns access, 48-pin TSOP, JEDEC-compatible but lacks Secured Silicon Sector and CFI query table	Requires custom bootloader for device identification; no hardware-locked ESN or password protection	Choose only if security features are unnecessary and legacy driver reuse outweighs long-term firmware authenticity requirements

Compared with S29GL032N90TFI030, the 020 variant trades speed for cost in stable-voltage systems, while the MX29GL32EHXFI-90G omits critical security and interoperability features-making the original part irreplaceable where secure boot, CFI auto-detection, or guaranteed 90 ns timing is required.

FAQ

Is S29GL032N90TFI030 pin-compatible with older S29GL032P or S29GL032N variants?

Yes - S29GL032N90TFI030 uses the same 48-pin TSOP footprint and electrical pinout as prior S29GL032N revisions (e.g., 020, 010). All control signals (CE#, WE#, OE#, RESET#, WP#/ACC), address lines (A0–A21), and data bus (DQ0–DQ15) retain identical mapping and timing behavior per JEDEC JESD22-A107 and JESD22-A114 standards.

Does this device support 8-bit data bus operation?

Yes - asserting BYTE# high configures the device for 8-bit mode, using only DQ0–DQ7 as the data bus while DQ8–DQ15 become no-connect. Address lines remain fully functional, and all command sequences operate identically; the device internally handles byte-to-word alignment during programming and erase.

What is the function of the WP#/ACC pin during normal operation versus programming?

When WP#/ACC is low, it permanently protects the first or last 64 KB sector from program/erase regardless of software protection settings. When driven high with 5.5 V (not 3.3 V), it enables accelerated programming for faster factory throughput - a feature disabled in field operation unless explicitly enabled via external HV circuitry.

Can the Secured Silicon Sector be reprogrammed after factory locking?

No - once the Secured Silicon Sector is locked (via command sequence or factory fuse), it becomes permanently read-only. The 256-byte region, including its 16-byte Electronic Serial Number, cannot be erased or rewritten. Unlocking requires physical device replacement; no software or voltage-based override exists.
