Product details
Overview
S29GL064S90FHIV20 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, hardware ECC for single-bit correction, and secure silicon region with factory-programmed 128-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 S29GL064S90FHIV20 datasheet, S29GL064S90FHIV20 pinout, S29GL064S90FHIV20 application, or S29GL064S90FHIV20 equivalent, key selection criteria include JEDEC-compliant command set, uniform 64-KB sector architecture, VIO-referenced I/O (1.65 V to VCC), and hardware reset (RESET#) with RY/BY# status signaling.
Technical Context
This device implements a parallel interface with separate CE#, WE#, and OE# controls, supporting both 16-bit word and 8-bit byte modes via BYTE# input. Its MIRRORBIT™ 65-nm process enables hot-hole erase and hot-electron programming with 100,000 erase cycles per sector and 20-year data retention.
It integrates on-die ECC logic that automatically corrects single-bit errors during read operations and reports multi-bit errors via status register. Sector protection includes persistent lock bits, password-protected sectors, and hardware WP#/ACC input that safeguards first/last sector independent of software settings.

Equivalent & Alternatives
The following parts are listed as comparable options for similar parallel NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S29GL064S90TFIV20 | Same die, 56-pin TSOP package instead of VBK048 BGA; identical timing and feature set | Preferred for through-hole prototyping or legacy PCB layouts with TSOP footprints | Select when mechanical compatibility with existing socketed designs is required |
| S29GL064S80TFIV20 | Slower 80 ns access time; otherwise identical architecture, ECC, and protection features | Suitable for cost-sensitive industrial HMIs where boot latency < 80 ns is acceptable | Choose for BOM cost reduction where 10 ns timing margin is not critical |
Compared with S29GL064S90FHIV20, the TSOP variant offers identical functionality in legacy-compatible packaging, while the 80 ns version trades minimal performance for lower unit cost-both retain full AEC-Q100 Grade 2 qualification and secure silicon capabilities.

FAQ
What is the function of the WP#/ACC pin on S29GL064S90FHIV20?
The WP#/ACC pin serves dual roles: when held low, it hardware-locks the first or last memory sector against program/erase operations regardless of software protection settings; when driven to elevated voltage (VHH), it enables accelerated programming mode for faster production-line firmware loading. This dual functionality is defined in the Infineon datasheet section 6.18 and supports both field reliability and manufacturing efficiency.
Does S29GL064S90FHIV20 support byte-wide data access?
Yes, S29GL064S90FHIV20 supports 8-bit data access when the BYTE# input is asserted low, configuring the DQ0–DQ7 pins as the active data bus while placing DQ8–DQ15 in high-impedance state. This mode is fully compliant with JEDEC standard JESD21-C and enables compatibility with 8-bit microcontroller buses without external data multiplexing.
How does the internal ECC operate during read cycles?
The S29GL064S90FHIV20 performs automatic single-bit error correction on every read access using dedicated on-die ECC circuitry. Corrected data is delivered to the bus transparently; uncorrectable multi-bit errors trigger status register flag DQ6 toggling and set the ECC Error bit (SR[2]) for host detection. No external ECC controller or software intervention is required per Infineon datasheet section 6.4.
Can the Secure Silicon Region be reprogrammed after factory locking?
No, the Secure Silicon Region (128-word / 256-byte area) can only be programmed once - either at factory or by the customer - and becomes permanently locked thereafter. Once the PPB (Persistent Protection Bit) is set, no further writes or erases are possible in that region, ensuring immutable storage of serial numbers, cryptographic keys, or calibration data as specified in datasheet section 6.17.
