Infineon Technologies S29GL064N11FFIS33

Overview

S29GL064N11FFIS33 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 bits, featuring 128 uniform 64 KB sectors, 90 ns access time, and Secured Silicon Sector with factory-programmable 128-word Electronic Serial Number. It serves as non-volatile program/data storage in boot code execution, firmware update, and embedded control systems.

For engineers reviewing the S29GL064N11FFIS33 datasheet, S29GL064N11FFIS33 pinout, S29GL064N11FFIS33 application, or S29GL064N11FFIS33 equivalent, key selection criteria include sector architecture (uniform vs. boot), VIO voltage range (1.65–3.6 V), CFI compliance, erase endurance (100,000 cycles/sector), and TSOP-48 package compatibility with JEDEC-standard command sets.

Technical Context

This device implements a 110 nm MirrorBit floating-gate NAND architecture with hot-hole erase and hot-electron programming, supporting both word (16-bit) and byte (8-bit via BYTE#) data bus operation. Its command-set architecture is fully JEDEC JESD21C compliant and includes CFI for host auto-configuration.

Hardware features include dedicated RY/BY# status output, RESET# for operation termination and boot initialization, WP#/ACC for accelerated programming and first/last sector protection, and VIO-referenced I/O enabling mixed-voltage system interfacing. Erase suspend/resume and program suspend/resume allow concurrent background operations across protected sectors.

FAQ

What is the function of the WP#/ACC pin on S29GL064N11FFIS33?

The WP#/ACC pin serves dual roles: when driven LOW, it permanently protects the first or last sector from accidental erase or program; when driven HIGH with 5.5 V, it activates accelerated programming mode, reducing write time by ~30% during manufacturing. This dual functionality eliminates need for external hardware write-protection switches while enabling high-throughput production programming.

Does S29GL064N11FFIS33 support 8-bit data bus operation?

Yes, it supports 8-bit mode via the BYTE# input. When BYTE# is LOW, only DQ0–DQ7 are active as an 8-bit data bus, and DQ15 functions as A−1 for extended addressing. This mode maintains full command compatibility and is commonly used in legacy 8-bit microcontroller interfaces where pin count reduction is critical.

How does the Secured Silicon Sector differ from standard flash sectors?

The Secured Silicon Sector is a dedicated 128-word (256-byte) region with factory-programmable 8-word Electronic Serial Number and permanent lock capability. Once locked, no further writes or erases are possible-even with unlock commands-making it ideal for storing immutable device identifiers, cryptographic keys, or calibration data that must survive field reprogramming.

Can S29GL064N11FFIS33 be used in systems with mixed 1.8 V and 3.3 V logic?

Yes, its VIO pin accepts 1.65–3.6 V, allowing independent I/O voltage referencing. With VIO = 1.8 V and VCC = 3.3 V, the device presents 1.8 V-compatible input thresholds and output levels while maintaining full internal 3.3 V core operation-enabling direct connection to 1.8 V FPGAs or ASICs without level translators.
