Infineon Technologies S29GL128P11TFIV10

Overview

S29GL128P11TFIV10 from Cypress Semiconductor is a 128 Mbit (16 MB) 3.0 V-only Page Mode Flash memory fabricated on 90 nm MirrorBit process technology, featuring 128 uniform 64 Kword (128 Kbyte) sectors, 25 ns page access time, and 90 ns random access time under regulated VCC. It supports VersatileI/O™ with VIO range 1.65–VCC, includes a 32-word write buffer for accelerated multi-word programming, and integrates Secured Silicon Sector with factory- or customer-programmable 8-word Electronic Serial Number - deployed in industrial embedded controllers requiring nonvolatile firmware storage with sector-level protection.

For engineers reviewing the S29GL128P11TFIV10 datasheet, S29GL128P11TFIV10 pinout, S29GL128P11TFIV10 application, or S29GL128P11TFIV10 equivalent, key selection criteria include uniform sector architecture (128 × 128 KB), WP#/ACC acceleration input, CFI compliance, suspend/resume capability for program/erase operations, and dual-package availability (TSOP-56 / Fortified BGA-64) with industrial temperature rating (–40°C to +85°C).

Technical Context

This device implements a synchronous/asynchronous hybrid command interface with dedicated state control logic, internal voltage generators for erase (VPP) and program (VHH), and automatic timing control via integrated timer and VCC detector. Its block diagram reveals independent X/Y decoders, sector switching matrix, and data gating aligned to DQ0–DQ15 I/O bus with BYTE#-controlled word/byte configuration.

It supports three operating voltage modes: Regulated VCC (3.0–3.6 V), Full VCC (2.7–3.6 V), and VersatileIO VIO (1.65–VCC with VCC = 2.7–3.6 V), each yielding distinct access timing profiles. The RY/BY# output provides real-time status of embedded algorithms, while RESET# enables hardware-initiated recovery to read mode without power cycle.

FAQ

What is the function of the VIO pin on S29GL128P11TFIV10?

The VIO pin supplies an independent voltage reference (1.65 V to VCC) that defines all input thresholds and output drive levels for address, control, and DQ signals. This VersatileI/O capability allows the device to interface seamlessly with 1.8 V, 2.5 V, or 3.3 V logic families without level shifters, while maintaining full VCC operation for core memory functions.

Does S29GL128P11TFIV10 support hardware reset, and how does it behave?

Yes, the RESET# pin provides asynchronous hardware reset: when asserted low, it immediately terminates any active program or erase operation, clears internal state machines, and returns the device to read array mode. After release, the device requires tRH = 100 ns minimum before accepting new commands, ensuring clean recovery without residual command state.

How does the WP#/ACC pin operate in protection versus acceleration modes?

When WP#/ACC is pulled low (VIL), it protects the highest or lowest sector (configurable at order time) from program/erase. When driven to VHH (~9 V), it enables Unlock Bypass Program mode, eliminating command overhead and reducing per-word programming time from 60 µs to 13.5 µs - used exclusively during high-volume manufacturing programming.

Can S29GL128P11TFIV10 be used in byte-mode configuration, and what changes occur?

Yes, asserting BYTE# = VIL configures the device for 8-bit data bus operation: DQ0–DQ7 become active I/O lines, DQ15/A-1 becomes the LSB address input (A-1), and internal addressing shifts to accommodate byte granularity. All command sequences remain identical, but data transfers occur one byte per cycle instead of one word.
