Infineon Technologies S29GL256P90FFIR13

Overview

S29GL256P90FFIR13 from Cypress Semiconductor is a 256 Mbit (32 MB), 3.0 V-only Page Mode Flash memory IC fabricated on 90 nm MirrorBit process technology. It delivers 90 ns random access time and 25 ns page access time, features a 32-word/64-byte write buffer, uniform 64 Kword sectors (256 total), and supports CFI for standardized interface. It is used in industrial embedded systems requiring nonvolatile code/data storage with sector-level protection.

For engineers reviewing the S29GL256P90FFIR13 datasheet, S29GL256P90FFIR13 pinout, S29GL256P90FFIR13 application, or S29GL256P90FFIR13 equivalent, key selection criteria include VIO-compatible I/O voltage scaling (1.65–VCC), WP#/ACC acceleration support, Secured Silicon Sector with factory-programmable ESN, suspend/resume capability, and industrial temperature range (–40°C to +85°C).

Technical Context

This device operates as a parallel-interface NOR Flash with byte/word configuration controlled by BYTE# input, and VersatileI/O™ logic enabling independent VIO supply (1.65–VCC) for I/O signaling while VCC powers core logic (2.7–3.6 V). Its architecture includes dedicated erase voltage and program voltage generators, state control logic for embedded algorithms, and sector switches enabling uniform 64 Kword erasure.

It implements two sector protection methods - Persistent Protection Bits (lockable per-sector bits) and Password Protection - alongside hardware WP#/ACC input that both accelerates programming (at VHH) and protects outermost sectors (at VIL). Ready/Busy# output provides real-time status of active program/erase operations.

FAQ

What is the function of the WP#/ACC pin on S29GL256P90FFIR13?

The WP#/ACC pin serves dual roles: at VIL (≤0.65 V), it hardware-protects the top or bottom sector from program/erase; at VHH (11.5–12.5 V), it enables Unlock Bypass mode, reducing single-word programming time to 13.5 µs and accelerating production programming throughput. Internal pull-up ensures safe default VIH state when unconnected.

Does S29GL256P90FFIR13 support both byte and word data configurations?

Yes - the BYTE# input selects bus width: at VIL, the device operates in 8-bit mode with DQ0–DQ7 active and DQ15/A-1 repurposed as LSB address; at VIH, it operates in 16-bit mode with full DQ0–DQ15 data path. This flexibility supports legacy 8-bit microcontrollers and modern 16-bit bus architectures without external glue logic.

How does the Secured Silicon Sector differ from standard flash sectors?

The Secured Silicon Sector is a dedicated 128-word (256-byte) region with factory- or customer-programmable 8-word electronic serial number (ESN). Once locked, its contents cannot be erased or rewritten - providing immutable device identity for anti-counterfeiting, license enforcement, and secure boot key storage, unlike standard user-accessible sectors.

Can S29GL256P90FFIR13 be used in systems with 1.8 V I/O interfaces?

No - the minimum VIO voltage is 1.65 V, but the device requires VIO ≤ VCC and VCC ≥ 2.7 V. A 1.8 V I/O interface would require VIO = 1.8 V and VCC ≥ 2.7 V, which violates the VIO ≤ VCC constraint unless VCC is also lowered - but VCC cannot drop below 2.7 V. Thus, 1.8 V-only systems need level-shifting or alternative Flash with true 1.8 V VIO support.
