Product details
Overview
S29GL064S90TFI020 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, industrial temperature range (–40°C to +85°C), and TSOP-48 packaging - deployed in boot firmware storage for industrial PLCs and network edge routers.
For engineers reviewing the S29GL064S90TFI020 datasheet, S29GL064S90TFI020 pinout, S29GL064S90TFI020 application, or S29GL064S90TFI020 equivalent, key selection criteria include JEDEC-compliant command set, Secure Silicon Region support, byte/word configuration via BYTE# input, and hardware reset (RESET#) integration for system boot recovery.
Technical Context
This device implements MIRRORBIT™ charge-trapping flash technology on a 65-nm process, enabling hot-hole erase and hot-electron programming with 100,000 erase cycles per sector and 20-year data retention. It supports both 16-bit and configurable 8-bit data bus modes using the BYTE# control input.
Hardware-level protection includes WP#/ACC-driven sector lock, low-VCC write inhibition, and RESET#-initiated operation abort. Erase/program suspend-resume functionality allows concurrent read access during background operations - critical for real-time firmware updates in embedded controllers.
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 - enables direct execution of code from flash in microcontroller boot loaders without caching |
| Write Buffer Size | 128-word (256-byte) - reduces multi-word programming overhead by batching writes |
| ECC Support | On-die hardware single-bit error correction - eliminates need for external ECC logic in safety-critical firmware storage |
| Supply Voltage | VCC = 2.7–3.6 V; VIO = 1.65–VCC - decouples I/O voltage from core supply for mixed-voltage system interfacing |
| Endurance | ≥100,000 erase/program cycles per sector - supports field firmware patching over product lifetime |
| Data Retention | 20 years typical at +85°C - validated for industrial deployments without refresh |
Pinout & Package
Package: 48-pin Thin Small Outline Package (TSOP-I, Type I), 12 mm × 20 mm × 1.2 mm body, standard JEDEC MO-142AC footprint.
| 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 in byte mode when BYTE# = L |
| DQ0–DQ15 | Data I/O | 16-bit bidirectional data bus; operates as 8-bit when BYTE# = L and A0 is ignored for byte selection |
| CE# | Chip Enable | Active-low chip select; device enters standby when CE# high, enabling power gating in multi-device systems |
| OE# | Output Enable | Controls output drivers only; allows read data latching without disabling chip or affecting internal state |
| WE# | Write Enable | Controls write timing; latches addresses/data during command sequences and program/erase cycles |
| RESET# | Hardware Reset | Asynchronous active-low reset that terminates ongoing operations and returns device to read array mode |
| RY/BY# | Ready/Busy Output | Open-drain status indicator - low during program/erase, high when ready for next command |
| WP#/ACC | Write Protect / Accelerated Program | Low = protects first/last sector; high + elevated voltage = enables accelerated programming for production line throughput |
| BYTE# | Bus Width Select | Low = 8-bit data mode (DQ0–DQ7 active); high = 16-bit mode (DQ0–DQ15 active) |
| VCC, VSS | Power / Ground | Single 3.0 V core supply; no separate I/O rail required - simplifies PCB power delivery |
Key Features
| Feature | Design Value |
|---|---|
| Secure Silicon Region | 128-word (256-byte) factory-lockable area with permanent electronic serial number - used for device identity binding in secure boot chains |
| Program/Erase Suspend-Resume | Allows host CPU to interrupt background erase/program to service interrupts or read other sectors - essential for deterministic real-time response |
| Unlock Bypass Mode | Reduces multi-word programming from 4 to 2 write cycles per word - cuts firmware update time by ~50% in host-controlled flashing |
| Common Flash Interface (CFI) | JEDEC-standard parameter table accessible via command sequence - enables automatic flash detection and driver configuration in OS/bootloader |
| Persistent Sector Protection | Non-volatile lock bits prevent accidental erase/write even after power cycle - replaces legacy 12 V protection schemes |

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 |
|---|---|---|---|
| S29GL064S90TFI010 | Same die, identical specs, but rated for Industrial Plus (–40°C to +105°C) temperature range | Required for extended-temperature industrial or under-hood automotive use where +85°C is insufficient | Select when ambient operating temperature exceeds +85°C; otherwise functionally interchangeable |
| S29GL064S90DHIV10 | 48-ball fine-pitch BGA (VBK048) package instead of TSOP-48; same electrical specs and timing | Used in space-constrained designs where board area or height budget prohibits TSOP | Choose for high-density PCB layouts; requires rework of footprint and signal routing |
Compared with S29GL064S90TFI020, the 010 variant extends thermal margin for harsh environments, while the DHIV10 variant trades package form factor for identical functionality - neither offers improved speed or density, but each addresses distinct mechanical or environmental constraints.

FAQ
Is S29GL064S90TFI020 compatible with legacy 3.3 V parallel NOR flash sockets?
No - it operates strictly at 3.0 V nominal (2.7–3.6 V), not 3.3 V. While VIO supports 1.65–VCC, the core VCC range does not overlap with standard 3.3 V flash tolerances. Direct socket replacement requires confirming system VCC regulation and adjusting voltage rails to meet Infineon's specified 3.0 V range.
Does this device support XIP (eXecute-In-Place) directly from flash?
Yes - its 70 ns access time and asynchronous parallel interface enable reliable XIP operation in microcontrollers with appropriate wait-state configuration. The device outputs valid data within 70 ns of address and OE# assertion, meeting timing requirements for most ARM Cortex-M and RISC-V cores running at ≤20 MHz bus frequency.
How is the Secure Silicon Region programmed and locked?
It is accessed via dedicated command sequences (Enter/Exit Secure Silicon Region) and programmed using standard Word Program commands. Locking is performed through Persistent Protection Bit (PPB) programming - once set, the region becomes permanently read-only and cannot be erased or rewritten, even with factory reset or voltage cycling.
Can BYTE# be used dynamically to switch between 8-bit and 16-bit modes during operation?
No - BYTE# is sampled only at power-up or after RESET# assertion. Its state determines bus width for the entire operational session. Changing BYTE# mid-operation has no effect and may cause undefined behavior; mode switching requires a hardware reset to reinitialize the interface configuration.
