Infineon Technologies S29GL128P10FFI023

Overview

S29GL128P10FFI023 from Cypress Semiconductor is a 128 Mbit (16 MB) 3.0 V-only Page Flash memory fabricated on 90 nm MirrorBit process technology, featuring uniform 64 Kword (128 Kbyte) sector architecture with 128 sectors, 25 ns page access time, and 100 ns random access time under regulated VCC. It supports VersatileI/O™ control (VIO = 1.65–VCC), 32-word write buffer programming, and Secured Silicon Sector with factory- or customer-programmable 8-word electronic serial number - deployed in industrial embedded controllers requiring nonvolatile code storage and field firmware updates.

For engineers reviewing the S29GL128P10FFI023 datasheet, S29GL128P10FFI023 pinout, S29GL128P10FFI023 application, or S29GL128P10FFI023 equivalent, key selection criteria include sector erase endurance (100,000 cycles), 20-year data retention, CFI compliance, hardware reset (RESET#), and WP#/ACC dual-function input for sector protection and VHH-accelerated programming during production.

Technical Context

This device implements a synchronous/asynchronous hybrid interface with byte/word configuration selected via BYTE# input, and uses internal state control logic to manage command sequences for read, program, and erase operations. Its block diagram integrates X/Y decoders, erase/PGM voltage generators, and a command register that interprets CFI-compliant opcodes including unlock bypass, suspend/resume, and advanced sector protection.

The VersatileI/O™ architecture decouples I/O voltage (VIO) from core supply (VCC), enabling interoperability with 1.8 V, 2.5 V, or 3.3 V host systems while maintaining full 3.0 V core operation. Sector erase timing is fixed at 0.5 s per 64 Kword sector, and write buffer programming achieves 13.5 µs/word with VHH acceleration.

FAQ

What is the function of the VIO pin on S29GL128P10FFI023?

The VIO pin sets the voltage level for all address, control, and data I/O signals independently of VCC. It accepts 1.65 V to VCC (2.7–3.6 V), allowing direct interfacing with 1.8 V or 2.5 V microcontrollers without external level shifters. This eliminates board-level translation circuitry and reduces signal integrity risk in mixed-voltage designs.

Does S29GL128P10FFI023 support true 8-bit bus operation?

Yes. When BYTE# is driven low, the device enters byte mode: DQ0–DQ7 become active data lines, and DQ15/A-1 functions as the LSB address input (A-1). This enables compatibility with 8-bit microcontrollers and simplifies PCB routing by halving the data bus width required for firmware storage tasks.

How is sector protection implemented on this device?

Sector protection uses two independent methods: persistent protection bits (locked via command sequence) and password protection (16-byte user-defined key). Both can be applied selectively to any sector. The WP#/ACC pin also provides hardware-level protection of the highest or lowest sector regardless of software settings, adding a physical layer of defense against accidental erasure.

Can S29GL128P10FFI023 be used in place of older S29GL128N devices?

No. The S29GL128P uses a different command set, lacks the "Toggle Bit" status reporting of the N-series, and introduces VIO and enhanced sector protection. Migration requires firmware driver updates and validation of timing margins, especially for RY/BY# polling and write buffer usage - it is not a drop-in replacement.
