Infineon Technologies S29GL256P90TFIR13

Overview

S29GL256P90TFIR13 from Cypress Semiconductor is a 256 Mbit (32 MB), 3.0 V-only Page Flash memory IC fabricated on 90 nm MirrorBit process technology, featuring 25 ns page access time, 90 ns random access time, and uniform 64 Kword (128 KB) sector architecture with 256 sectors. It supports VersatileI/O™ (VIO = 1.65–VCC), 32-word write buffer programming, and Secured Silicon Sector with 128-word electronic serial number for secure device identification in embedded boot code storage.

For engineers reviewing the S29GL256P90TFIR13 datasheet, S29GL256P90TFIR13 pinout, S29GL256P90TFIR13 application, or S29GL256P90TFIR13 equivalent, key selection considerations include industrial temperature range (–40°C to +85°C), TSOP-56 package compatibility, CFI compliance, hardware reset (RESET#), and WP#/ACC dual-function pin for sector protection and VHH-accelerated programming.

Technical Context

This device implements a synchronous/non-volatile memory architecture with dedicated X/Y decoders, erase/program voltage generators, and state control logic enabling concurrent suspend/resume of program and erase operations. Its VersatileI/O™ interface decouples I/O voltage (VIO) from core supply (VCC), supporting mixed-voltage system interfacing across 1.65–3.6 V ranges while maintaining full read/write functionality.

The 32-word write buffer enables burst programming of up to 64 bytes per command, reducing effective per-word programming time to 13.5 µs under VHH acceleration. Sector erase time is fixed at 0.5 s per 64 Kword sector, with 100,000 erase cycles endurance and 20-year data retention-validated under industrial operating conditions.

FAQ

What is the function of the WP#/ACC pin on S29GL256P90TFIR13?

The WP#/ACC pin serves two distinct roles: at VIL, it protects the first or last sector from program/erase operations regardless of software protection settings; when driven to VHH (12 V), it enables unlock bypass mode, accelerating programming throughput by eliminating command overhead between write buffer loads. This dual functionality supports both security and high-volume manufacturing requirements.

Does S29GL256P90TFIR13 support byte-wide data access?

Yes, byte-wide access is supported via the BYTE# input: when pulled low, DQ0–DQ7 become active data lines and DQ15/A-1 functions as the LSB address input. The device retains full 16-bit word mode capability when BYTE# is high, allowing seamless integration into both 8-bit and 16-bit microcontroller buses without external glue logic.

How does the Secured Silicon Sector enhance system security?

The Secured Silicon Sector provides a dedicated 128-word (256-byte) region that can be factory- or customer-programmed with a unique electronic serial number (ESN). Once locked, this region becomes permanently read-only and immune to erase commands, enabling hardware-rooted device authentication, license enforcement, and anti-counterfeiting in regulated applications such as medical and industrial control systems.

Can S29GL256P90TFIR13 operate with VIO = 1.8 V while VCC = 3.3 V?

Yes, the VersatileI/O™ architecture explicitly supports VIO = 1.65–VCC. With VCC = 3.3 V, VIO may be set to 1.8 V, configuring all address, control, and data pins to recognize 1.8 V logic thresholds and drive 1.8 V-compatible outputs. This eliminates external level shifters when interfacing with low-voltage SoCs or FPGAs, simplifying PCB layout and reducing system power.
