Infineon Technologies S29GL064N90TAI010

Overview

S29GL064N90TAI010 from Cypress Semiconductor is a 64 Mbit (8 MB), 3.0 V single-power-supply MirrorBit Flash memory IC organized as 4,194,304 words × 16 bits, featuring 90 ns access time, 25 ns page read time, and uniform 64 KB sector architecture with 128 sectors. It supports 16-bit data bus operation, CFI compliance, and is used for firmware storage in industrial control systems, network routers, and embedded boot code applications.

For engineers reviewing the S29GL064N90TAI010 datasheet, S29GL064N90TAI010 pinout, S29GL064N90TAI010 application, or S29GL064N90TAI010 equivalent, key selection criteria include sector protection mode (Persistent/Password), VIO voltage range (1.65–3.6 V), RY/BY# status signaling, WP#/ACC hardware write acceleration, and TSOP-48 package compatibility.

Technical Context

This device implements a command-set-compatible JEDEC-standard Flash interface with internal state machine control, supporting program/erase suspend/resume, CFI query, and autoselect modes. It uses hot-electron injection for programming and hot-hole assisted erase per sector, with DQ7 polling and DQ6 toggle bits for operation status feedback.

The Secured Silicon Sector provides factory- or customer-lockable 256-byte region with 8-word electronic serial number; Advanced Sector Protection includes persistent lock bits and password-based sector lockdown. VIO input independently sets I/O voltage level (1.65–3.6 V), decoupling logic thresholds from VCC (2.7–3.6 V).

FAQ

What is the function of the BYTE# pin on S29GL064N90TAI010?

The BYTE# pin configures the device data bus width: when pulled high, it enables 16-bit (x16) operation using DQ0–DQ15; when pulled low, it selects 8-bit (x8) mode using DQ0–DQ7 only. This allows hardware compatibility with both 8-bit and 16-bit microcontrollers without redesigning the PCB layout or changing firmware drivers.

Does S29GL064N90TAI010 support hardware reset during active programming?

Yes - the active-low RESET# pin asynchronously terminates any ongoing program or erase operation and returns the device to read mode. This is critical for system recovery after power glitches or watchdog timeouts, and ensures predictable boot behavior even if firmware update is interrupted mid-cycle.

How does the WP#/ACC pin operate in accelerated programming mode?

When WP#/ACC is driven high with ≥VCC + 0.5 V (typically 3.6–4.2 V), it activates internal high-voltage circuitry that speeds up programming by ~30%, reducing multi-word write time. In normal operation (≤VCC), it functions as write-protect for the first or last sector - retaining protection even during accelerated writes.

Can S29GL064N90TAI010 be used in systems with 1.8 V I/O interfaces?

Yes - the VIO pin accepts 1.65–3.6 V, so applying 1.8 V to VIO configures all inputs and outputs to 1.8 V logic thresholds, enabling direct connection to 1.8 V SoCs or FPGAs without external level shifters. VCC remains at 3.0 V ±0.3 V for core memory operation.
