Infineon Technologies S29GL064N11TFIV20

Overview

S29GL064N11TFIV20 from Infineon Technologies (formerly Cypress) is a 64 Mbit, 3.0 V single-power-supply MirrorBit Flash memory organized as 4,194,304 words (16-bit bus), featuring 90 ns access time, 100,000 erase cycles per sector, and 20-year data retention. It supports uniform sector architecture with 128 × 64 KB sectors and integrates Secured Silicon Sector with factory-programmable 128-word Electronic Serial Number for secure device identification in boot firmware storage.

For engineers reviewing the S29GL064N11TFIV20 datasheet, S29GL064N11TFIV20 pinout, S29GL064N11TFIV20 application, or S29GL064N11TFIV20 equivalent, key selection criteria include JEDEC-compliant command set, VIO-referenced VersatileI/O™ operation (1.65–3.6 V), hardware reset (RESET#), Ready/Busy# status signaling, and boot-sector-compatible erase flexibility for embedded system firmware storage.

Technical Context

This NOR Flash implements a synchronous command interface with internal address/data latching, enabling full compatibility with standard microprocessor bus timing. It uses hot-electron injection for programming and hot-hole assisted erase at the sector level, supporting both uniform and boot-sector configurations.

The device features dual voltage domains: VCC (2.7–3.6 V) powers core logic and memory array, while VIO (1.65–3.6 V) independently sets I/O buffer thresholds-enabling seamless interfacing with mixed-voltage host systems. Sector protection includes persistent lock bits and password-protected regions, with CFI compliance enabling automatic device detection and configuration by host firmware.

FAQ

What is the function of the WP#/ACC pin on S29GL064N11TFIV20?

The WP#/ACC pin serves dual functions: when held low, it hardware-protects the first or last sector regardless of software protection settings; when driven high with an elevated voltage (VHH ≈ 11–12 V), it enables accelerated programming for faster factory programming throughput. This dual-mode operation is confirmed in the datasheet's Section 8.16 and Figure 1 timing diagrams.

Does S29GL064N11TFIV20 support x8 data bus mode?

Yes, it supports x8 mode via the BYTE# input: when BYTE# is low, only DQ0–DQ7 are active as an 8-bit data bus, with DQ15–DQ8 disabled. This is explicitly defined in Section 8.1 "Word/Byte Configuration" and validated in the pin description table (Section 4), where BYTE# is listed as functional across all package variants.

How does the Secured Silicon Sector differ from standard sectors?

The Secured Silicon Sector is a dedicated 128-word (256-byte) region that can be permanently locked at factory or by customer command; once locked, no further writes or erases are possible-even under accelerated programming conditions. It contains a unique 8-word electronic serial number and is accessed only via specific unlock-and-read command sequences per Section 8.15.

Is S29GL064N11TFIV20 compatible with standard JEDEC Flash command sets?

Yes, it is fully compliant with the JEDEC Standard JESD21-C for single-power-supply Flash memory, including command definitions for read, program, sector erase, chip erase, autoselect, and CFI query. All command sequences match JEDEC-specified opcodes and timing windows, as verified in Section 10 of the datasheet and Table 10-1.
