Product details
Overview
S29GL064S90TFI033 from Infineon is a 64 Mb (8 MB) parallel NOR flash memory IC with 3.0 V single-supply operation, 70 ns access time, 128-word write buffer, internal hardware ECC for single-bit correction, and secure silicon region supporting factory- or customer-programmed 128-word electronic serial number. It serves as boot code storage in industrial microcontroller systems requiring AEC-Q100 Grade 2 compliance (–40°C to +105°C).
For engineers reviewing the S29GL064S90TFI033 datasheet, S29GL064S90TFI033 pinout, S29GL064S90TFI033 application, or S29GL064S90TFI033 equivalent, this device delivers verified sector erase architecture, JEDEC-compliant command set, programmable boot sectors, and hardware reset (RESET#) integration for embedded firmware recovery.
Technical Context
The S29GL064S90TFI033 implements a uniform sector architecture with 128 × 32-Kword (64-KB) sectors and supports both 8-bit and 16-bit data bus configurations via BYTE# control. Its MIRRORBIT™ 65-nm process enables hot-hole assisted erase and hot-electron injection programming.
It integrates dual status monitoring-DQ7 data# polling and DQ6 toggle bits-and hardware RY/BY# output for real-time program/erase cycle detection. The device uses VIO-referenced I/O (1.65 V to VCC) for flexible voltage domain interfacing and includes persistent sector protection with lock register and password-based sector locking.
Key Specifications

Pinout & Package
Package: 48-lead TSOP (Type I, standard pitch), RoHS-compliant, industrial temperature grade.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A22 | Address Inputs | 23-bit address bus supporting full 64 Mb addressing; A0 selects byte/word mode when BYTE# is active |
| DQ0–DQ15 | Data I/O | 16-bit bidirectional data bus; operates as 8-bit with BYTE# = low, enabling legacy 8-bit controller compatibility |
| CE# | Chip Enable | Active-low chip select; must be asserted before WE# or OE# to enable device operation |
| OE# | Output Enable | Active-low read strobe; controls output drivers independently of CE# for multiplexed bus timing |
| WE# | Write Enable | Active-low write strobe; latches addresses and data during command sequences and programming |
| RESET# | Hardware Reset | Active-low asynchronous reset; terminates ongoing erase/program and returns device to read mode for boot recovery |
| RY/BY# | Ready/Busy Output | Open-drain status flag indicating active programming/erase; used for hardware flow control without polling |
| WP#/ACC | Write Protect / Accelerated Program | Low = first/last sector protection; high-voltage = accelerated programming mode for production line throughput |
Key Features
| Feature | Design Value |
|---|---|
| Secure Silicon Region | 128-word (256-byte) factory- or customer-lockable area with permanent electronic serial number for device identity binding |
| Program/Erase Suspend | Allows host to interrupt ongoing program/erase to read or program other sectors-enabling concurrent firmware update and runtime code execution |
| Unlock Bypass Mode | Reduces multi-word programming command overhead from 4 to 2 write cycles, cutting total write latency by ~35% |
| Common Flash Interface (CFI) | JEDEC-standard CFI query table enables automatic flash detection and configuration in bootloader without hard-coded parameters |
| VIO-Referenced I/O | I/O voltage range 1.65 V to VCC allows direct interface with 1.8 V, 2.5 V, or 3.3 V controllers while maintaining 3.0 V core operation |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S29GL064S90TFI020 | Same die, 48-pin TSOP but rated for Industrial (–40°C to +85°C) only; no AEC-Q100 qualification | Lacks automotive temperature and stress testing; unsuitable for under-hood use | Select only for cost-sensitive industrial designs where extended temperature is not required |
| MX29GL640EHTI-90G | 64 Mb parallel NOR flash from Macronix; 90 ns access, no integrated ECC, CFI-compatible but no Secure Silicon Region | Requires external ECC logic and lacks factory-programmable serial number for device binding | Choose when lower unit cost outweighs need for hardware ECC and secure identity features |

FAQ
Is S29GL064S90TFI033 pin-compatible with earlier S29GL064N or S29GL064P variants?
No. S29GL064S90TFI033 uses a revised pinout: WP#/ACC replaces the dedicated ACC pin found on S29GL064N/P, and RY/BY# functionality is enhanced with faster transition timing. Board-level redesign is required for migration due to signal routing and timing differences in erase suspend and reset behavior.
Does the Secure Silicon Region support customer programming after shipment?
Yes. The 128-word Secure Silicon Region can be programmed and permanently locked either at Infineon's factory or in-system by the customer using the Enter/Exit Secure Silicon Region command sequence. Once locked via PPB bit, no further writes or erases are possible-even with elevated VPP-ensuring irreversible identity binding.
What is the minimum VIO voltage supported for reliable 16-bit data transfers?
The minimum VIO voltage for guaranteed 16-bit operation is 1.65 V, as specified in the datasheet's "DC Characteristics" table. At VIO = 1.65 V, setup/hold times increase by 2.5 ns versus VIO = 3.0 V, and DQ outputs meet VOH/VOL specs only when driven into ≥10 kΩ loads. For robust 16-bit timing margins, VIO ≥ 2.3 V is recommended.
Can Erase Suspend be used during Chip Erase operations?
No. Erase Suspend is supported only for Sector Erase commands-not Chip Erase. Attempting to issue an Erase Suspend command during Chip Erase results in undefined behavior and may corrupt the entire array. The datasheet explicitly restricts suspend/resume functionality to individual sector erase cycles to maintain data integrity guarantees.
