Product details
Overview
S29GL064N90BFI033 from Infineon Technologies (formerly Cypress) is a 64 Mbit, 3.0 V single-power-supply MirrorBit Flash memory IC organized as 4,194,304 words (16-bit bus), featuring 90 ns access time, 100,000 erase cycles per sector, and 20-year data retention. It implements uniform sector architecture with 128 × 64 KB sectors and supports boot code storage in embedded microcontroller systems requiring nonvolatile program storage.
For engineers reviewing the S29GL064N90BFI033 datasheet, S29GL064N90BFI033 pinout, S29GL064N90BFI033 application, or S29GL064N90BFI033 equivalent, key selection criteria include JEDEC-compliant command set, Secured Silicon Sector with factory-programmed 128-word ESN, flexible sector protection (Persistent/Password), and dual-voltage I/O control via VIO (1.65–3.6 V).
Technical Context
This device uses 110 nm MirrorBit process technology to enable simultaneous hot-hole erase and hot-electron programming across full sectors. Its architecture integrates dedicated erase voltage and program voltage generators, state control logic, and CFI-compliant interface for automatic host system identification.
The device supports both uniform and boot-sector configurations, though S29GL064N90BFI033 is a uniform-sector model. It features hardware reset (RESET#), ready/busy status (RY/BY#), and programmable write protection (WP#/ACC) with accelerated programming capability at elevated voltage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 64 Mbit (4,194,304 × 16-bit words); enables storage of ~8 MB firmware images in compact footprint. |
| Access Time | 90 ns (VCC = 2.7–3.6 V, VIO = 2.7–3.6 V); meets timing requirements for 11 MHz synchronous read in legacy MCU interfaces. |
| Erase Endurance | 100,000 cycles per sector; supports field firmware updates over product lifetime without wear leveling. |
| Data Retention | 20 years at +85°C; ensures long-term reliability in industrial temperature-grade applications. |
| Supply Voltage | VCC = 2.7–3.6 V, VIO = 1.65–3.6 V; allows interfacing with mixed-voltage SoCs using independent I/O rail control. |
| Page Read Buffer | 8-word (16-byte) buffer with 25 ns page access; reduces latency for sequential instruction fetches. |
| Write Buffer | 16-word (32-byte) buffer; cuts multi-word programming time by batching writes before internal commit. |
Pinout & Package
Package: 48-pin TSOP (Type I, standard thin small outline package, 12 × 20 mm body, 0.5 mm pitch). Pinout validated per Infineon Document 001-98525 Rev. *B, Figure 1 (S29GL064N Models 03/04).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A21 | Address inputs | 22-bit address bus supporting full 4M-word addressing; A-1 (DQ15) used as MSB in x16 mode. |
| DQ0–DQ15 | Data I/O bidirectional bus | 16-bit parallel data path; DQ7/DQ6 used for polling/toggle status during program/erase operations. |
| CE# | Chip enable | Active-low chip select; device enters standby when CE# high, enabling power gating in multi-device systems. |
| OE# | Output enable | Active-low output control; decouples data bus drivers during read cycles to prevent contention. |
| WE# | Write enable | Active-low strobe for command latching and write cycles; synchronized with address/data setup/hold timing. |
| RESET# | Hardware reset | Active-low asynchronous reset; terminates ongoing operation and returns device to read mode for safe boot recovery. |
| RY/BY# | Ready/Busy output | Open-drain status signal indicating active program/erase; used for interrupt-driven host synchronization. |
| WP#/ACC | Write protect / Accelerated program | Low = sector protection; high + elevated voltage = faster programming (factory throughput mode). |
| BYTE# | Bus width select | Low = x16 mode; high = x8 mode (DQ0–DQ7 only active); enables compatibility with 8-bit microcontrollers. |
| VIO | I/O supply voltage | Defines logic thresholds for all address/control/data pins; enables 1.8 V or 3.3 V interface without level shifters. |
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 and Password-based protection modes; prevents unauthorized firmware overwrite without hardware reset or password entry. |
| Program/Erase Suspend | Allows host to pause programming/erasing to service interrupts or read other sectors; essential for real-time OS firmware updates. |
| CFI Compliance | JEDEC JESD68-defined parameter tables accessible via command; enables automatic flash detection and configuration in bootloader code. |
| Unlock Bypass Mode | Reduces multi-word programming overhead from 4 to 2 write cycles per word; improves production programming throughput by ~50%. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S29GL064S90TFI020 | Same density and speed, but 56-pin TSOP package; no BYTE# pin - fixed x16 bus width. | Lacks byte-mode flexibility; unsuitable for designs requiring 8-bit microcontroller compatibility. | Select when board layout accommodates larger 56-pin footprint and x16-only interface suffices. |
| MX29GL640EHTI-90G | 64 Mbit, 90 ns, but uses 1.8 V core (VCC = 1.7–2.0 V); VIO range 1.7–3.6 V; different command set. | Not JEDEC software-compatible; requires custom driver adaptation; lower power but higher integration risk. | Choose only when ultra-low active current (<15 mA read) is critical and firmware stack can be modified. |
Compared with S29GL064S90TFI020 and MX29GL640EHTI-90G, the S29GL064N90BFI033 uniquely combines TSOP-48 compactness, BYTE#-enabled x8/x16 configurability, and full JEDEC software compatibility - making it optimal for cost-sensitive, field-upgradable embedded systems where design reuse and toolchain continuity matter.

FAQ
Is S29GL064N90BFI033 compatible with legacy S29GL064N designs?
Yes - it is a direct replacement within the same TSOP-48 package and shares identical pinout, command set, timing parameters, and electrical specifications per Infineon Document 001-98525 Rev. *B. No PCB or firmware changes are required for migration from earlier S29GL064N variants with same speed grade and package.
What is the function of the VIO pin, and how should it be biased?
VIO sets input threshold voltages for all address, control, and data pins. It must be connected to the host system's I/O rail voltage (1.65–3.6 V), independent of VCC. For 3.3 V systems, tie VIO to 3.3 V; for 1.8 V interfaces, tie VIO to 1.8 V - enabling seamless mixed-voltage operation without external level shifters.
How does the Secured Silicon Sector differ from standard protected sectors?
The Secured Silicon Sector is a dedicated 128-word region programmed and locked at the factory with a unique 8-word Electronic Serial Number. Unlike software-protected sectors, it cannot be erased or rewritten after locking - even with RESET# or power cycling - providing tamper-proof device identity for secure boot and license enforcement.
Can S29GL064N90BFI033 operate in x8 mode, and what is required?
Yes - assert BYTE# = HIGH to enable x8 mode, which restricts data transfer to DQ0–DQ7 only. In this mode, DQ8–DQ15 become no-connect, and address lines shift accordingly (A0–A20 used instead of A0–A21). The device remains fully functional for 8-bit microcontrollers without external glue logic.
