Infineon Technologies S29GL064N90TFI063

Overview

S29GL064N90TFI063 from Infineon Technologies (formerly Cypress) is a 64 Mbit, 3.0 V single-power-supply MirrorBit Flash memory organized as 4,194,304 words (8,388,608 bytes), 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 operates across VIO = 1.65–3.6 V for flexible I/O voltage control - deployed in industrial control firmware storage and boot code retention.

For engineers reviewing the S29GL064N90TFI063 datasheet, S29GL064N90TFI063 pinout, S29GL064N90TFI063 application, or S29GL064N90TFI063 equivalent, key selection factors include JEDEC-compliant command set compatibility, Secured Silicon Sector with factory-programmed 128-word ESN, Advanced Sector Protection (Persistent + Password), and support for Erase/Program Suspend & Resume in embedded systems requiring concurrent firmware updates and runtime reads.

Technical Context

This device implements a 110 nm MirrorBit floating-gate architecture enabling simultaneous hot-hole erase and hot-electron programming. Its dual-bus operation supports 16-bit word mode or 8-bit byte mode via BYTE# input, with all address/control/data levels referenced to VIO rather than VCC - allowing mixed-voltage system integration without level shifters.

The command-set architecture includes CFI compliance for automatic device identification, Unlock Bypass mode (2-cycle programming vs. standard 4-cycle), and hardware-assisted protection via WP#/ACC and RESET# pins. Status reporting uses DQ7 Data# Polling, DQ6/DQ2 toggle bits, and RY/BY# output - eliminating need for external timing controllers during erase/program operations.

FAQ

What is the function of the WP#/ACC pin on S29GL064N90TFI063?

The WP#/ACC pin serves dual functions: as WP# it permanently protects the first or last sector from program/erase when pulled low; as ACC it accepts 5.0 V (±0.3 V) to accelerate internal programming voltage generation, reducing write time by up to 65% during factory production. This pin is not used for standard 3.0 V operation and must be tied to VSS or left floating unless high-speed programming is required.

Does S29GL064N90TFI063 support 8-bit data bus operation?

Yes - when the BYTE# input is driven low, the device operates in 8-bit mode using DQ0–DQ7 as the data bus while DQ8–DQ15 become unused. Address lines remain unchanged, and all commands retain identical timing. This mode is fully supported in both read and write operations and requires no configuration register changes.

How is the Secured Silicon Sector protected after factory programming?

Once programmed and locked, the Secured Silicon Sector (128 words) becomes permanently read-only and immune to erase or program commands. Locking is performed via a dedicated command sequence (0x60 → 0xD0) that sets internal fuses; no voltage or timing variation can reverse this state. The 8-word Electronic Serial Number within this sector is pre-programmed and unique per unit.

Can S29GL064N90TFI063 be used in systems with 1.8 V I/O voltage?

Yes - the VIO supply pin accepts 1.65–3.6 V, so 1.8 V is within specification. All inputs (address, control, data) and outputs are referenced to VIO, not VCC. When VIO = 1.8 V, input thresholds become ~0.9 V (VIH) and ~0.6 V (VIL), matching standard 1.8 V logic families without level shifters - provided VCC remains 2.7–3.6 V for core operation.
