Product details
Overview
S29GL064S70TFI020 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, internal hardware ECC for single-bit correction, and secure silicon region with factory-programmed 8-word electronic serial number. It serves as boot code storage in industrial control systems requiring AEC-Q100 Grade 2 qualification (–40°C to +105°C).
For engineers reviewing the S29GL064S70TFI020 datasheet, S29GL064S70TFI020 pinout, S29GL064S70TFI020 application, or S29GL064S70TFI020 equivalent, this device supports JEDEC-compliant command sets, sector-level erase suspend/resume, unlock bypass programming, and flexible 16-bit/8-bit data bus configuration via BYTE# input.
Technical Context
The S29GL064S70TFI020 implements MIRRORBIT™ charge-trapping flash technology on a 65-nm process, enabling simultaneous hot-hole erase and hot-electron programming. Its architecture features uniform 32-Kword (64-KB) sectors with optional boot-sector variants and supports both CE#/OE#/WE# discrete control and hardware reset via RESET#.
It integrates automatic ECC detection and correction during read cycles, uses VIO-referenced I/O (1.65 V to VCC) for mixed-voltage system interfacing, and provides persistent sector protection plus password-protected secure silicon region - all compliant with Common Flash Interface (CFI) for host auto-configuration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 64 Mb (4,194,304 words × 16-bit), organized as 128 × 64-KB uniform sectors |
| Access Time | 70 ns at VCC = 2.7–3.6 V; enables real-time boot code fetch in microcontroller-based systems |
| Write Buffer Size | 128-word (256-byte); reduces multi-word programming overhead by >60% vs. single-word writes |
| ECC Capability | Internal hardware single-bit error correction per 512-byte sector; eliminates need for external ECC logic |
| Operating Temperature | –40°C to +105°C (AEC-Q100 Grade 2); qualified for under-hood automotive ECUs and industrial HMIs |

Pinout & Package
Package: 48-lead TSOP (Type I, 12 mm × 20 mm × 1.2 mm), RoHS-compliant, industrial temperature grade.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A22 | Address Inputs | 23-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) |
| CE# | Chip Enable | Active-low chip select; deassertion places device in low-power standby (40 µA) |
| OE# | Output Enable | Controls output buffer; allows read sharing across multiple devices on same data bus |
| WE# | Write Enable | Initiates command latching or data programming; must be pulsed for each write cycle |

| RY/BY# | Ready/Busy Output | Open-drain status signal; low during internal operations, high when ready for next command |
| WP#/ACC | Write Protect / Accelerated Program | Low = protects first/last sector; high + 5.5 V = enables accelerated programming in production |
Key Features
| Feature | Design Value |
|---|---|
| Secure Silicon Region | 128-word (256-byte) factory-locked area with 8-word electronic serial number; prevents post-deployment tampering of boot keys or calibration data |
| Erase Suspend/Resume | Pauses background sector erase to allow immediate read/program of other sectors; critical for real-time firmware update without system stall |
| Unlock Bypass Mode | Reduces multi-word programming command overhead from 4 to 2 write cycles; cuts total page programming time by ~35% |
| Persistent Sector Protection | Non-volatile lock bits disable program/erase permanently until reset via dedicated command; replaces legacy 12-V protection schemes |
| VIO-Referenced I/O | I/O voltage range 1.65 V to VCC; enables direct interface with 1.8 V, 2.5 V, or 3.3 V controllers without level shifters |

FAQ
Does S29GL064S70TFI020 support 8-bit data bus operation?
Yes. When the BYTE# pin is asserted low, the device operates in 8-bit mode using DQ0–DQ7 only, while DQ8–DQ15 are disabled. This mode maintains full command set compatibility and preserves all security and ECC features. The configuration is hardware-selectable and does not require firmware reinitialization.
What is the function of the WP#/ACC pin in normal operation?
In standard operation, WP#/ACC acts as a write protect input: pulling it low disables programming and erasure of the first or last sector, regardless of software protection settings. During manufacturing, applying 5.5 V to this pin enables accelerated programming mode, reducing write times by up to 40% without altering device functionality or reliability.
How does the Secure Silicon Region differ from standard sectors?
The Secure Silicon Region is a dedicated 128-word (256-byte) sector that can be permanently locked at factory or by customer command. Once locked, no further writes or erases are possible-even with elevated voltage or unlock sequences. It contains an 8-word electronic serial number and is used for immutable keys, calibration data, or anti-counterfeiting identifiers.
Is S29GL064S70TFI020 compatible with legacy S29GL064N devices?
No. Although both are 64 Mb parallel NOR flashes, S29GL064S70TFI020 uses 65-nm MIRRORBIT™ technology and requires updated command sequences for advanced features like erase suspend and secure silicon access. Pinout is identical, but firmware must be revised to use CFI query and new status register mapping per Infineon's migration guide.
