Infineon Technologies S29GL256P11FFI013

Overview

S29GL256P11FFI013 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 256 uniform 128 KB sectors, 25 ns page access time, and 110 ns random access time at regulated VCC. It supports VersatileI/O™ with VIO range 1.65–VCC, 32-word write buffer, and Secured Silicon Sector for electronic serial number programming - deployed in industrial embedded controllers requiring nonvolatile firmware storage with sector-level protection.

For engineers reviewing the S29GL256P11FFI013 datasheet, S29GL256P11FFI013 pinout, S29GL256P11FFI013 application, or S29GL256P11FFI013 equivalent, key selection criteria include 110 ns random access timing under industrial temperature (–40°C to +85°C), Pb-free 64-ball Fortified BGA (LAA064) package, CFI-compliant interface, and hardware-accelerated programming via WP#/ACC input at VHH.

Technical Context

This device implements a synchronous/asynchronous hybrid command-set architecture with dedicated state control logic, erase voltage generator, and PGM voltage generator enabling embedded erase and program algorithms. Its block diagram integrates X/Y decoders, sector switches, and data gating aligned to a 23-bit address bus (A22–A0) and 16-bit DQ bus (DQ15–DQ0), supporting both word and byte configurations via BYTE# input.

Operation relies on three critical voltage domains: VCC (2.7–3.6 V), VIO (1.65–VCC), and VHH (11.5 V for acceleration). The RY/BY# output provides real-time status of embedded operations, while RESET# enables hardware-initiated recovery to read mode - essential for fail-safe boot code execution in automotive and industrial systems.

FAQ

What is the function of the WP#/ACC pin on S29GL256P11FFI013?

The WP#/ACC pin serves dual functions: at VIL, it protects the highest or lowest sector from accidental writes; at VHH (11.5 V), it activates unlock bypass mode and reduces single-word programming time to 13.5 µs. This acceleration is critical during high-volume manufacturing programming and field firmware updates, directly improving throughput without requiring additional external circuitry.

Does S29GL256P11FFI013 support byte-wide data access?

Yes, byte-wide access is supported via the BYTE# input: when pulled low, DQ0–DQ7 become active and DQ15/A-1 functions as the LSB address line. This mode enables compatibility with 8-bit microcontrollers and reduces bus routing complexity on dense PCBs, while maintaining full 16-bit word access capability when BYTE# is high.

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

The Secured Silicon Sector is a dedicated 128-word (256-byte) region that can be permanently locked at the factory or by the customer using an 8-word electronic serial number. Unlike standard sectors, it cannot be erased or rewritten once locked - providing hardware-enforced immutability for device identification, cryptographic keys, or regulatory compliance data required in medical and defense applications.

Can S29GL256P11FFI013 operate with VIO = 1.8 V while VCC = 3.3 V?

Yes, the VersatileI/O™ architecture explicitly supports VIO = 1.65–VCC, so VIO = 1.8 V and VCC = 3.3 V is a valid configuration. This allows direct interfacing with 1.8 V logic families (e.g., ARM Cortex-M peripherals) without level shifters, reducing BOM cost and signal integrity risk - confirmed in the datasheet's VersatileIO VIO operating range specification.
