Infineon Technologies S29GL256P90TFCR13

Overview

S29GL256P90TFCR13 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, uniform 64 Kword sectors (256 total), and 32-word write buffer for accelerated multi-word programming. It operates across industrial temperature range (–40°C to +85°C) in 56-pin TSOP package and is used in embedded boot code storage for networking routers and industrial HMIs.

For engineers reviewing the S29GL256P90TFCR13 datasheet, S29GL256P90TFCR13 pinout, S29GL256P90TFCR13 application, or S29GL256P90TFCR13 equivalent, key selection criteria include sector erase endurance (100,000 cycles), data retention (20 years), VersatileI/O™ voltage flexibility (VIO = 1.65–VCC), CFI compliance, and hardware reset (RESET#) with ready/busy status signaling (RY/BY#).

Technical Context

This NOR Flash device implements a synchronous command-set architecture with autoselect, page read, and write buffer programming modes. Its block diagram integrates X/Y decoders, sector switches, erase/program voltage generators, and state control logic managed via command register sequences.

It supports dual configuration (word/byte mode via BYTE#), persistent and password-based advanced sector protection, secured silicon sector with factory- or customer-programmable 128-word serial number, and suspend/resume for program/erase operations - enabling robust firmware update and secure boot in resource-constrained systems.

FAQ

What is the maximum operating temperature range for S29GL256P90TFCR13?

The S29GL256P90TFCR13 is rated for industrial temperature operation from –40°C to +85°C, verified per Cypress datasheet Document Number 002-00886 Rev. *B, Section 11.2. This range applies to all electrical specifications including access times, current consumption, and erase endurance ratings.

Does S29GL256P90TFCR13 support byte-mode operation?

Yes, S29GL256P90TFCR13 supports byte-mode operation via the BYTE# input pin. When BYTE# is driven low, DQ0–DQ7 become active data lines and DQ15/A-1 functions as the LSB address input, enabling 8-bit microcontroller interfacing without external data bus multiplexing.

How many sectors does S29GL256P90TFCR13 have, and what is their size?

S29GL256P90TFCR13 contains exactly 256 uniform sectors, each sized at 64 Kwords (128 Kbytes). This architecture is confirmed in the General Description section of the datasheet and enables predictable erase timing (0.5 s per sector) and flexible firmware partitioning.

Is the Secured Silicon Sector programmable after device shipment?

Yes, the Secured Silicon Sector (128 words / 256 bytes) can be programmed and permanently locked either at the factory or by the end customer using defined command sequences. Once locked, the contents - including an 8-word electronic serial number - cannot be altered, providing permanent device identity.
