Product details
Overview
S29GL032N90FFIS30 from Infineon Technologies (formerly Cypress) is a 32-Mbit, 16-bit-wide single-supply MirrorBit Flash memory with 90 ns access time, 25 ns page read time, and uniform 64 KB sector architecture. It operates from 2.7–3.6 V VCC and 1.65–3.6 V VIO, supports CFI compliance, and is used for embedded boot code storage in industrial controllers and network edge devices.
For engineers reviewing the S29GL032N90FFIS30 datasheet, S29GL032N90FFIS30 pinout, S29GL032N90FFIS30 application, or S29GL032N90FFIS30 equivalent, key selection criteria include JEDEC software compatibility, Secured Silicon Sector with factory-programmed 128-word ESN, Advanced Sector Protection (Persistent & Password), Erase/Program suspend/resume capability, and 48-pin TSOP package with VIO-referenced I/O flexibility.
Technical Context
This device implements a command-set-compatible, single-power-supply NOR Flash architecture with hot-electron programming and hot-hole assisted erase. Its 110 nm MirrorBit process enables 100,000 erase cycles per sector and 20-year data retention while maintaining full JEDEC pin and software compatibility.
The flexible I/O interface uses VIO to define all input thresholds and output levels, supporting mixed-voltage system integration. Sector erase granularity (64 KB uniform sectors), 16-word write buffer, and CFI-compliant identification allow host firmware to dynamically configure memory mapping and protection without hard-coded assumptions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 32 Mbit (2,097,152 words × 16-bit), organized as 64 uniform 64 KB sectors |
| Access Time | 90 ns max at VCC = 2.7–3.6 V - determines minimum CPU wait-state timing for random reads |
| Page Read Time | 25 ns max - enables burst fetch of 8-word (16-byte) buffer for instruction streaming |
| Erase Endurance | 100,000 cycles per sector - supports field firmware updates over product lifetime |
| Data Retention | 20 years typical at 125°C - validated for automotive-grade thermal stress environments |
| VIO Range | 1.65–3.6 V - allows direct interfacing with 1.8 V, 2.5 V, or 3.3 V logic without level shifters |
| Supply Voltage | Single 2.7–3.6 V VCC - eliminates need for dual-rail power design in embedded systems |
Pinout & Package
Package: 48-pin TSOP (Standard Thin Small Outline Package), 12 × 20 mm body, lead pitch 0.5 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A21 | Address inputs | 22-bit address bus; A-1 (DQ15) multiplexed as MSB for byte/word mode selection |
| DQ0–DQ15 | Data I/O bidirectional bus | 16-bit parallel interface; DQ15 functions as A-1 in word mode or DQ15 in byte mode via BYTE# |
| CE#, OE#, WE# | Chip, Output, Write Enable controls | Independent gating enables interleaved access and low-power partial activation |
| WP#/ACC | Write Protect / Accelerated Program input | Logic-low protects first/last sector; high-voltage on ACC reduces program time during production |
| RY/BY# | Ready/Busy open-drain output | Active-low signal indicates active erase/program cycle; enables polling-free interrupt-driven operation |
| RESET# | Hardware reset input | Aborts ongoing operation and returns device to read mode - critical for safe boot recovery |
| VIO | I/O voltage reference | Sets all input thresholds and output drive levels - decouples I/O voltage from core VCC |
Key Features
| Feature | Design Value |
|---|---|
| Secured Silicon Sector | 128-word (256-byte) factory-locked region with 8-word ESN - provides immutable device identity for secure boot and licensing |
| Advanced Sector Protection | Persistent Sector Protection (PPB lock bit) and Password Sector Protection (128-bit password) - prevents unauthorized firmware modification in deployed units |
| Erase/Program Suspend & Resume | Pause erase/program in one sector to read/program another - enables real-time OS task switching during flash maintenance |
| CFI Compliance | Standardized query table at address 0x0055, 0x0055, 0x00AA - allows generic flash drivers to auto-detect geometry and command set |
| Unlock Bypass Mode | Two-cycle command sequence replaces four-cycle standard - cuts multi-word programming overhead by 50% in production test |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NOR Flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S29GL032N90TFIR20 | Same die, 48-ball fine-pitch BGA (8.15 × 6.15 mm); no WP#/ACC pin - lacks hardware-accelerated programming | Used where board space is constrained and production throughput is less critical than footprint | Select when PCB layout requires BGA and factory programming acceleration is unnecessary |
| MX29GL320EBTI-90G | Micron 32 Mb NOR Flash; 90 ns access, but only 64 Kword sectors and no Secured Silicon Sector or Password Protection | Deployed in cost-sensitive consumer gateways where security features are omitted | Choose only if CFI compatibility and basic sector erase suffice, and ESN/secure boot are not required |
Compared with S29GL032N90FFIS30, the BGA variant trades WP#/ACC functionality for compactness, while the Micron part omits Secured Silicon and password protection - making the original TSOP version uniquely suited for secure, production-optimized industrial boot memory.

FAQ
What is the function of the VIO pin on S29GL032N90FFIS30?
The VIO pin sets the voltage reference for all input thresholds and output drive levels. With VIO ranging from 1.65 V to 3.6 V, it enables direct interfacing with 1.8 V, 2.5 V, or 3.3 V logic families without external level shifters. This decouples I/O signaling from the core VCC supply, simplifying mixed-voltage system design and reducing BOM count.
Does S29GL032N90FFIS30 support true 8-bit data bus operation?
Yes - when BYTE# is asserted low, the device operates in 8-bit mode using DQ0–DQ7 only, with DQ8–DQ15 disabled. In this mode, A0 selects even/odd bytes, and the internal address counter increments by one per access. This mode is fully supported in both read and program operations and maintains full command-set compatibility.
How is the Secured Silicon Sector protected after factory programming?
The Secured Silicon Sector is permanently locked via fuse-based or OTP (one-time-programmable) circuitry. Once programmed and locked - either at factory or by the customer using the Lock Register command - no further writes or erases are possible within that 128-word region. The 8-word Electronic Serial Number remains readable but immutable, providing cryptographically verifiable device identity.
Can Erase Suspend be used during a Chip Erase operation?
No - Erase Suspend is supported only for Sector Erase commands, not Chip Erase. The datasheet explicitly restricts suspend/resume functionality to individual sector erase cycles. Chip Erase is an atomic operation that cannot be interrupted or paused; attempting to issue a suspend command during chip erase has no effect and does not alter device state.
