Product details
Overview
S29GL064S90BHI040 from Infineon is a 64 Mb (8 MB) parallel NOR flash memory with 3.0 V single-supply operation, 70 ns access time, 128-word write buffer, and integrated hardware ECC for single-bit error correction. It features uniform 64-KB sectors, secure silicon region with factory-programmed 16-byte serial number, and operates across –40°C to +85°C industrial temperature range in 48-lead TSOP package.
For engineers reviewing the S29GL064S90BHI040 datasheet, S29GL064S90BHI040 pinout, S29GL064S90BHI040 application, or S29GL064S90BHI040 equivalent, this device supports boot code storage, firmware updates, and secure configuration data retention in embedded control systems requiring JEDEC-compliant command set and robust in-system sector protection.
Technical Context
The S29GL064S90BHI040 implements MIRRORBIT™ flash architecture on 65-nm process, enabling simultaneous hot-hole erase and hot-electron programming. It supports 16-bit word-wide data bus with BYTE#-controlled 8-bit mode and uses VIO-referenced I/O (1.65 V to VCC) for flexible voltage domain interfacing.
Its command-set compatibility with JEDEC JESD21-C ensures interoperability with legacy host controllers. Hardware features include RESET#, RY/BY#, WP#/ACC, and dedicated CE#/OE#/WE# controls - enabling deterministic timing for boot ROM access and concurrent program/erase suspend-resume operations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 64 Mb (4,194,304 words × 16 bits), organized as 128 uniform 64-KB sectors |
| Access Time | 70 ns typical - enables direct execution of boot code from flash without cache penalty in microcontroller-based systems |
| Write Buffer Size | 128-word (256-byte) page buffer - reduces multi-word programming time by >60% vs. single-word writes |
| ECC Capability | On-die hardware single-bit error correction - eliminates need for external ECC logic in safety-critical firmware storage |
| Endurance | 100,000 erase/program cycles per sector - supports field firmware update frequency up to once per day for >27 years |
| Data Retention | 20 years typical at 85°C - meets long-lifecycle requirements for industrial automation and automotive ECUs |
| Operating Voltage | VCC = 2.7–3.6 V; VIO = 1.65–VCC - allows independent I/O voltage scaling for mixed-signal SoC interface compatibility |
Pinout & Package
Package: 48-lead TSOP (Type I, 12 mm × 20 mm × 1.2 mm), RoHS-compliant, industrial temperature grade (–40°C to +85°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A21 | Address Inputs | 22-bit address bus supporting full 4-Mword addressing; A0 selects LSB in 16-bit mode |
| DQ0–DQ15 | Data I/O | 16-bit bidirectional data bus; BYTE# controls 8-bit mode (DQ0–DQ7 only active) |
| CE# | Chip Enable | Active-low chip select; must be asserted before OE#/WE# for valid read/write cycles |
| OE# | Output Enable | Controls output buffer; used during read to gate data onto DQ bus |
| WE# | Write Enable | Controls write latching; low pulse initiates command or data load into internal registers |
| RESET# | Hardware Reset | Asynchronous active-low reset; terminates ongoing erase/program and returns to read mode |
| RY/BY# | Ready/Busy Output | Open-drain status flag; low = operation in progress, high = ready for next command |
| WP#/ACC | Write Protect / Accelerated Program | Low = protects first/last sector; high + VHH = enables accelerated programming for production line speed-up |
| VIO | I/O Supply Reference | Sets input threshold and output drive level; decoupled from VCC for mixed-voltage system interfacing |
Key Features
| Feature | Design Value |
|---|---|
| Secure Silicon Region | 128-word (256-byte) factory-locked area with 16-byte electronic serial number - provides immutable device identity for secure boot and licensing |
| Program/Erase Suspend-Resume | Allows host to interrupt ongoing program/erase to service real-time read requests - essential for multitasking firmware loaders |
| Unlock Bypass Mode | Reduces multi-word programming overhead from 4 to 2 write cycles per word - cuts firmware update time by ~50% in host-controlled flashing |
| Advanced Sector Protection | Combines persistent lock bits and password-protected sectors - prevents unauthorized firmware modification without physical access or known credentials |
| Automatic Hardware ECC | Single-bit correction with no software intervention - maintains data integrity across temperature cycling and long-term storage without host CPU overhead |

Equivalent & Alternatives
The following parts are listed as comparable options for similar parallel NOR flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S29GL064S90TFI020 | Same die, 56-lead TSOP package, 90 ns access time, industrial temp | Larger footprint; slightly slower timing margin for high-speed microcontroller interfaces | Select when board layout accommodates wider TSOP and timing budget permits 20 ns longer access |
| MX29GL640EHTI-90G | 64 Mb parallel NOR, 90 ns, Macronix; no integrated ECC, no secure silicon region | Lacks hardware ECC and factory-locked serial number - requires external error handling and identity management | Select for cost-sensitive applications where firmware integrity is managed in software and device ID is not required |
Compared with S29GL064S90BHI040, the S29GL064S90TFI020 trades speed and package size for mechanical compatibility, while MX29GL640EHTI-90G omits ECC and secure silicon - increasing host firmware complexity but reducing BOM cost by ~12%.

FAQ
Is S29GL064S90BHI040 pin-compatible with earlier S29GL064N or S29GL064P devices?
No. S29GL064S90BHI040 uses a 48-lead TSOP package with updated pin mapping for VIO and enhanced WP#/ACC functionality. It is not mechanically or electrically compatible with S29GL064N (44-pin TSOP) or S29GL064P (48-pin TSOP with different RESET# and RY/BY# placement). Migration requires PCB redesign and firmware timing validation.
Does the Secure Silicon Region support customer programming after shipment?
Yes - the 128-word Secure Silicon Region can be programmed and permanently locked by the customer using the Enter Secure Silicon Region command sequence. Once PPB lock bit is set, no further writes or erases are possible. Factory programming provides a default 16-byte serial number, but full 256-byte space is available for user-defined keys or certificates.
What is the minimum VIO voltage required for reliable operation with 3.3 V VCC?
The minimum VIO voltage is 1.65 V per datasheet specification. At VCC = 3.3 V, VIO must be ≥1.65 V and ≤3.3 V to maintain correct input thresholds and output drive strength. Operating VIO below 1.65 V risks setup/hold violation on address and control inputs, leading to command decode errors or spurious writes.
Can Erase Suspend be used during Chip Erase mode?
No. Erase Suspend is supported only during Sector Erase operations. Chip Erase is an atomic operation that cannot be interrupted or suspended. Attempting Erase Suspend during Chip Erase has no effect - RY/BY# remains low until completion, and DQ6 toggle/DQ7 polling reflects full chip erase status only.
