Product details
Overview
S29GL064S80TFIV20 from Infineon is a 64 Mb (8 MB) parallel NOR flash memory IC using 65-nm MIRRORBIT™ technology, operating from a single 3.0 V supply with 70 ns access time and integrated hardware ECC for single-bit error correction. It features 128 uniform 64-KB sectors, 100,000 erase cycles per sector, and industrial temperature range (–40°C to +85°C), deployed in boot firmware storage for embedded microcontrollers.
For engineers reviewing the S29GL064S80TFIV20 datasheet, S29GL064S80TFIV20 pinout, S29GL064S80TFIV20 application, or S29GL064S80TFIV20 equivalent, key selection criteria include JEDEC-compliant command set, VIO-referenced I/O (1.65 V to VCC), Secure Silicon Region with factory-programmed 16-byte serial number, and support for Program/Erase Suspend/Resume in real-time firmware update systems.
Technical Context
This device implements a parallel asynchronous interface with separate CE#, WE#, and OE# controls, supporting both 16-bit word and 8-bit byte configurations via BYTE# input. Its architecture includes a 128-word write buffer and 8-word read buffer to accelerate multi-word programming and page reads.
The internal ECC engine operates transparently during read operations, correcting single-bit errors without host intervention, while the Secure Silicon Region provides a permanently lockable 256-byte area accessible only via dedicated command sequences - not mapped into main array address space.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 64 Mb (4,194,304 words × 16 bits), organized as 128 × 64-KB uniform sectors |
| Access Time | 70 ns typical - enables direct execution (XIP) from flash in MCU boot loaders without wait states at moderate clock speeds |
| Voltage Supply | Single 3.0 V core; I/O voltage (VIO) independently configurable from 1.65 V to VCC - supports mixed-voltage system interfacing |
| ECC Support | On-the-fly single-bit error correction with no software overhead - ensures data integrity in long-term industrial deployments |
| Erase Endurance | ≥100,000 cycles per sector - validated for frequent firmware field updates in remote monitoring devices |
| Data Retention | 20 years typical at 85°C - meets extended lifecycle requirements for automotive ECUs and industrial controllers |
| Temperature Range | Industrial: –40°C to +85°C - qualified per AEC-Q100 Grade 3 for under-hood automotive applications |
Pinout & Package
Package: 48-lead TSOP (Type I, standard pitch, 12 mm × 20 mm). Pinout validated per Infineon datasheet Rev. *K, pages 11–12 and connection diagram Fig. 3-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A21 | Address Inputs | 22-bit address bus supporting full 4-Mword addressing; A0 selects LSB in word mode or byte within word in byte mode |
| DQ0–DQ15 | Data I/O | 16-bit bidirectional data bus; direction controlled by WE# and OE#; BYTE# determines 8-/16-bit operation |
| CE# | Chip Enable | Active-low chip select - must be asserted for all read/write/erase operations; enables low-power standby when deasserted |
| OE# | Output Enable | Active-low control for data bus drivers - allows shared bus operation with other peripherals without contention |
| WE# | Write Enable | Active-low strobe for latching addresses/data during command sequences and programming; initiates internal write cycles |
| RY/BY# | Ready/Busy Output | Open-drain status flag - low during active program/erase; used for hardware polling instead of software data polling |
| RESET# | Hardware Reset | Active-low asynchronous reset - terminates ongoing operations and returns device to read mode; ties directly to system reset rail |
| WP#/ACC | Write Protect / Accelerated Program | Logic-low enables hardware sector protection (first/last sector); high-voltage on this pin enables accelerated programming in production |
Key Features
| Feature | Design Value |
|---|---|
| Secure Silicon Region | 128-word (256-byte) factory-lockable area with 16-byte electronic serial number - used for device identity binding and secure boot key storage |
| Program/Erase Suspend | Pause active programming or erasing to service interrupts or read other sectors - essential for deterministic real-time firmware update handlers |
| Unlock Bypass Mode | Reduces multi-word programming overhead from 4 to 2 write cycles per word - cuts total firmware patch time by ~50% in host-controlled updates |
| Advanced Sector Protection | Persistent and password-based sector locking - prevents accidental or malicious overwrite of bootloader or calibration data in field-deployed units |
| Common Flash Interface (CFI) | JEDEC-standard query table at fixed address - enables automatic flash detection and configuration in generic bootloader frameworks (e.g., U-Boot) |

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 |
|---|---|---|---|
| S29GL064S90TFIV20 | 90 ns access time; otherwise identical architecture, package, and feature set | Lower performance margin for XIP in high-clock-rate MCUs; same endurance, ECC, and security features | Select when system timing budget permits relaxed access latency and cost optimization is prioritized |
| MX29GL640EHTI-90G | Macronix device with 90 ns access, JEDEC-compatible command set, but no Secure Silicon Region or factory-programmed serial number | Lacks hardware-enforced device identity and persistent sector locking - requires external security co-processor for secure boot | Choose only if Secure Silicon Region is not required and legacy Macronix ecosystem integration exists |
Compared with S29GL064S90TFIV20, the -80 variant delivers 20 ns faster access for tighter timing margins; versus MX29GL640EHTI-90G, it provides integrated silicon-level security features absent in the alternative, reducing BOM count and certification effort in safety-critical designs.

FAQ
Is S29GL064S80TFIV20 pin-compatible with earlier S29GL064N or S29GL064P variants?
No. While functionally similar, the S29GL064S uses a revised pinout - notably relocating RESET# and RY/BY# - and requires PCB layout revision. The datasheet explicitly states "not backward compatible" in Section 1, Product Selector Guide, due to changed signal assignments and enhanced VIO referencing.
Does the Secure Silicon Region support customer programming after shipment?
Yes, the Secure Silicon Region can be programmed and locked by the customer in-system using the Enter/Exit Secure Silicon Region command sequence (Section 8.5 of datasheet). Factory programming provides an initial 16-byte serial number; subsequent writes require unlocking via command, then locking permanently with PPB bit.
What is the role of the VIO pin, and how must it be connected?
VIO sets the reference voltage for all address, control, and data I/O levels. It must be connected to the host system's I/O voltage rail (1.65 V to VCC), not tied to VCC. Mismatched VIO causes setup/hold violations and command failures - confirmed in Section 6.2 and Figure 3-1 of the datasheet.
Can S29GL064S80TFIV20 operate in byte mode on a 16-bit bus?
Yes. When BYTE# is driven low, the device operates in 8-bit mode: DQ0–DQ7 become data lines, and DQ8–DQ15 are tri-stated. Address lines remain fully functional, enabling byte-level access to firmware binaries without bus-width conversion logic.
