Product details
Overview
S29GL256P11TAIV20 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, 110 ns random access time, uniform 64 Kword sectors (256 total), and VersatileI/O™ support with VIO range 1.65–VCC. It serves as non-volatile program/data storage in embedded microcontroller boot loaders and industrial firmware updates.
For engineers reviewing the S29GL256P11TAIV20 datasheet, S29GL256P11TAIV20 pinout, S29GL256P11TAIV20 application, or S29GL256P11TAIV20 equivalent, key selection factors include sector erase endurance (100,000 cycles), secured silicon sector for electronic serial number, write buffer programming efficiency (13.5 µs/word with VHH), and dual-package availability (TSOP-56 / BGA-64).
Technical Context
This device implements a synchronous command-set architecture compliant with Common Flash Interface (CFI), supporting both word and byte configurations via BYTE# control. Its internal state machine handles autonomous program and erase operations with suspend/resume capability and real-time status reporting via RY/BY#.
The VersatileI/O™ interface decouples I/O voltage (VIO) from core supply (VCC), enabling interoperability with 1.8 V, 2.5 V, or 3.3 V logic systems while maintaining full 2.7–3.6 V VCC operation. Sector protection employs both persistent lock bits and password-based methods, with WP#/ACC providing hardware-accelerated programming and outer-sector write protection.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Page Flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S29GL256S11TFIV20 | Same density and timing, but 64-ball Fortified BGA package (LAA064) instead of TSOP-56 | Required for space-constrained PCB layouts; no change in thermal or signal integrity assumptions | Select when board area is constrained and BGA assembly capability exists |
| MX29GL256FHI-11G | Macronix equivalent; identical 256 Mbit density, 110 ns access, but lacks VersatileI/O™ and secured silicon sector | Acceptable for cost-sensitive designs without VIO flexibility or secure ID requirements | Choose only if VIO decoupling and electronic serial number are not required |
Compared with S29GL256S11TFIV20, this TSOP variant offers easier prototyping and rework; versus MX29GL256FHI-11G, it delivers superior I/O voltage flexibility and built-in security features-critical for certified industrial and automotive deployments.

FAQ
What is the maximum operating temperature range for S29GL256P11TAIV20?
The S29GL256P11TAIV20 is rated for industrial temperature operation from –40°C to +85°C. This range is validated across all electrical specifications including access times, programming voltages, and data retention. The device maintains full functionality-including RY/BY# status reporting and suspend/resume operations-within this envelope, with no derating required.
Does S29GL256P11TAIV20 support byte-wide data access?
Yes, byte-wide access is supported via the BYTE# input: when pulled low, DQ0–DQ7 become active I/O lines and DQ15/A-1 functions as the LSB address bit. This enables direct connection to 8-bit microcontrollers without external data bus multiplexing. All command sequences-including autoselect and sector protection-are fully functional in byte mode.
How does the Write Protect/Acceleration (WP#/ACC) pin function in practice?
WP#/ACC operates in two distinct modes: at VIL, it protects the highest or lowest sector (configurable by model number) from accidental writes; at VHH (~9 V), it enables unlock bypass programming, reducing command overhead and accelerating production-line programming by up to 4×. Internal pull-up ensures safe default (VIH) behavior when unconnected.
Can the Secured Silicon Sector be reprogrammed after initial locking?
No-the Secured Silicon Sector can be programmed once (by factory or customer) and then permanently locked using either persistent lock bits or password protection. Once locked, no further writes or erases are possible-even with valid passwords or unlock sequences. This one-time programmability ensures cryptographic binding of device identity for anti-counterfeiting and license enforcement.
