Infineon Technologies S29GL128P10TAI020

Overview

S29GL128P10TAI020 from Cypress Semiconductor is a 128 Mbit (16 MB), 3.0 V-only Page Flash memory IC 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 (3.0–3.6 V). It supports VersatileI/O™ with VIO range 1.65–VCC, 32-word write buffer, and Secured Silicon Sector with factory- or customer-programmable 8-word electronic serial number - deployed in industrial embedded boot code storage.

For engineers reviewing the S29GL128P10TAI020 datasheet, S29GL128P10TAI020 pinout, S29GL128P10TAI020 application, or S29GL128P10TAI020 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 pin for sector protection and VHH-accelerated programming.

Technical Context

This device implements a synchronous/asynchronous hybrid interface with dedicated CE#, OE#, and WE# control lines, enabling standard NOR Flash command-set operation including autoselect, program suspend/resume, and advanced sector protection via persistent bits or password methods. Its architecture integrates an on-chip state controller, erase/program voltage generators, and timing logic to execute embedded algorithms without external intervention.

The VersatileI/O™ design decouples I/O voltage (VIO) from core supply (VCC), allowing interoperability with 1.8 V, 2.5 V, or 3.3 V host interfaces while maintaining full 3.0 V core operation. The 8-word page read buffer and 32-word write buffer operate independently of CPU bus timing, reducing effective latency during burst reads and multi-word writes.

FAQ

What is the function of the WP#/ACC pin on S29GL128P10TAI020?

The WP#/ACC pin serves dual roles: at VIL, it protects the highest or lowest address sector from accidental erase/program; at VHH (12 V), it enables Unlock Bypass Program mode, reducing effective programming time to 13.5 µs per word. Internal pull-up ensures safe default VIH state when unconnected.

Does S29GL128P10TAI020 support both byte and word data configurations?

Yes - BYTE# input selects bus width: at VIL, DQ0–DQ7 are active with DQ15/A-1 functioning as LSB address for 8-bit mode; at VIH, DQ0–DQ15 operate as full 16-bit data bus. This enables compatibility with 8-bit microcontrollers and 16-bit DSPs 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 physically isolated from main array, factory-programmable with unique 8-word electronic serial number, and permanently lockable via hardware fuse or software command - preventing overwrite even during bulk erase operations.

Can S29GL128P10TAI020 operate with VIO = 1.8 V while VCC = 3.3 V?

Yes - VersatileI/O™ allows VIO = 1.65–VCC, so 1.8 V I/O signaling is fully supported with VCC = 3.3 V. All address, control, and data pins conform to 1.8 V logic thresholds, eliminating need for level translators when interfacing with low-voltage FPGAs or ASICs.
