Infineon Technologies S29GL064N11TFIV13

Overview

S29GL064N11TFIV13 from Infineon Technologies (formerly Cypress) is a 64 Mbit, 3.0 V single-power-supply MirrorBit Flash memory IC organized as 4,194,304 words (8,388,608 bytes), featuring 90 ns access time, 16-bit data bus with BYTE#-enabled 8-bit mode, and uniform sector architecture with 128 × 64 KB sectors. It operates across VCC = 2.7–3.6 V and VIO = 1.65–3.6 V, and is used for boot code storage and firmware updates in industrial control systems.

For engineers reviewing the S29GL064N11TFIV13 datasheet, S29GL064N11TFIV13 pinout, S29GL064N11TFIV13 application, or S29GL064N11TFIV13 equivalent, key selection criteria include JEDEC software compatibility, Secured Silicon Sector with factory-programmed 128-word ESN, Advanced Sector Protection (Persistent + Password), Erase/Program Suspend & Resume, and CFI compliance for host system auto-configuration.

Technical Context

This device implements a command-set-compatible, single-supply NOR Flash architecture using 110 nm MirrorBit process technology. It supports both uniform and boot-sector configurations, with hardware reset (RESET#), ready/busy status (RY/BY#), and write-protect acceleration via WP#/ACC input at elevated voltage.

Internal logic includes a state controller managing command latching, address/data buffering (8-word read buffer, 16-word write buffer), and autonomous erase/program timing. Sector-level erasure enables non-volatile code updates without full-chip reprogramming, while DQ7 polling and DQ6 toggle bits provide real-time operation status without external timing dependencies.

FAQ

Is S29GL064N11TFIV13 pin-compatible with earlier S29GL064N variants?

Yes - S29GL064N11TFIV13 uses the 48-pin TSOP package with identical pinout to other S29GL064N models in the same package type (e.g., S29GL064N11TFIV10). All address, data, control, and power pins match exactly, including RESET#, RY/BY#, and WP#/ACC assignments per Figure 1 of datasheet 001-98525 Rev. *B.

Does this device support 8-bit data bus operation?

Yes - the BYTE# input enables 8-bit mode: when pulled low, DQ0–DQ7 become the active data bus while DQ8–DQ15 are tri-stated. This is fully supported in both read and write operations and requires no additional command sequences; the device automatically adapts bus width based on BYTE# state at access initiation.

What is the function of the WP#/ACC pin, and how is it used in practice?

WP#/ACC serves dual roles: as WP# (write protect), a logic-low signal locks the first or last sector against accidental erase/program; as ACC (accelerated program), applying 5.5 V ± 0.5 V enables faster internal programming voltages. In production, ACC is driven by a dedicated HV circuit; in field updates, it may be tied to VCC through a resistor if acceleration is not required.

Can the Secured Silicon Sector be reprogrammed after factory locking?

No - once the Secured Silicon Sector is locked (via command sequence or factory setting), it becomes permanently read-only. The 128-word region contains a factory-programmed 8-word Electronic Serial Number and supports customer-defined code/data before locking, but post-lock access is read-only and irreversible, ensuring tamper-proof device identity.
