Product details
Overview
S29GL256P90TFCR20 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 100,000 erase cycles per sector - deployed in industrial embedded systems for firmware storage and boot code execution.
For engineers reviewing the S29GL256P90TFCR20 datasheet, S29GL256P90TFCR20 pinout, S29GL256P90TFCR20 application, or S29GL256P90TFCR20 equivalent, key selection criteria include VersatileI/O™ voltage flexibility (VIO = 1.65–VCC), 32-word write buffer acceleration, CFI compliance, hardware reset (RESET#), and WP#/ACC dual-function pin behavior under VHH bias.
Technical Context
This device implements a synchronous/asynchronous hybrid interface with dedicated CE#, OE#, and WE# control lines, supporting byte/word configuration via BYTE# input and dynamic I/O voltage scaling through VIO. Its internal state machine executes embedded erase and program algorithms without external timing control.
The Secured Silicon Sector provides factory- or customer-programmable 128-word electronic serial number with lock capability, while Advanced Sector Protection supports both persistent bit and password-based locking mechanisms - enabling secure firmware update and boot partition protection in mission-critical applications.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Page Flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S29GL256S90TFIR20 | Same density and speed, but uses 64-ball Fortified BGA (LAA064) instead of TSOP; no NC pins on A24/A25 | BGA variant suits space-constrained PCBs with higher I/O routing density; lacks TSOP's mechanical robustness in vibration-prone environments | Select for compact designs where board area is constrained and reflow compatibility is verified |
| MX29GL256FHTI-90G | Micron equivalent with identical 256 Mbit density, 90 ns speed, and TSOP-56 package; supports CFI but lacks VersatileI/O™ and Secured Silicon Sector | No VIO flexibility or hardware-secured serial number - requires external security layer for authentication use cases | Choose when cost sensitivity outweighs need for embedded security or mixed-voltage interfacing |
Compared with S29GL256S90TFIR20 and MX29GL256FHTI-90G, the S29GL256P90TFCR20 uniquely delivers VIO-driven voltage adaptability and factory-lockable silicon ID in a TSOP package - making it optimal for industrial firmware storage where interface flexibility and traceability are mandatory.

FAQ
What is the function of the WP#/ACC pin on S29GL256P90TFCR20?
The WP#/ACC pin serves dual roles: at VIL, it protects the highest or lowest address sector from accidental writes; when driven to VHH (12 V), it accelerates programming throughput by enabling unlock bypass mode and eliminating command latency between write operations - critical for high-volume manufacturing programming.
Does S29GL256P90TFCR20 support byte-level writes?
No - this device operates exclusively in word (16-bit) or byte (8-bit) data width modes selected by BYTE#, but all programming occurs in minimum 16-bit word units. The 32-word write buffer accepts up to 64 bytes per operation, but individual byte modification requires full-word erase and rewrite due to NOR Flash architecture constraints.
How does the Secured Silicon Sector differ from standard flash sectors?
The Secured Silicon Sector is a dedicated 128-word (256-byte) region with permanent lock capability: once locked, its contents - including an 8-word electronic serial number - cannot be altered or erased, even with chip erase commands. It resides outside the main array and is accessed via unique command sequences defined in the datasheet.
Can S29GL256P90TFCR20 operate with VIO = 1.8 V while VCC = 3.3 V?
Yes - VersatileI/O™ allows VIO to be set independently from 1.65 V to VCC. With VCC = 3.3 V, VIO may be configured to 1.8 V to interface directly with low-voltage microcontrollers or FPGAs, eliminating external level shifters while maintaining full read/write functionality and timing compliance.
