Cypress Semiconductor Corp S29GL01GT10GHI010

Overview

S29GL01GT10GHI010 from Infineon is a 1 Gb (128 MB) parallel NOR flash memory using 45-nm MIRRORBIT™ technology, operating from 2.7 V to 3.6 V with 100 ns random access time and 15 ns page access time. It features a 512-byte write buffer, internal single-bit ECC, uniform 128-KB sectors, and supports industrial temperature range (–40°C to +85°C). It is used in boot code storage for industrial controllers requiring fast XIP execution and reliable non-volatile data retention.

For engineers reviewing the S29GL01GT10GHI010 datasheet, S29GL01GT10GHI010 pinout, S29GL01GT10GHI010 application, or S29GL01GT10GHI010 equivalent, key selection criteria include parallel ×16 bus interface, 100,000 program/erase cycles, OTP array with four lockable SSR regions, CFI compliance, and support for suspend/resume during erase and program operations.

Technical Context

This device implements an asynchronous parallel interface with byte/word boundary addressing and supports both 8-bit and 16-bit data bus configurations. Its embedded algorithm controller (EAC) manages all program and erase operations, including automatic ECC generation and correction during read, and status monitoring via Status Register, Data Polling, or RY/BY# pin.

The architecture includes dedicated address space overlays (ASOs) for Device ID/CFI, Status Register, Data Polling, Sector Protection Registers (SSR), and ECC status. Sector protection uses volatile and non-volatile methods per sector, and the 2048-byte OTP array contains four lockable regions-SSR0 factory-locked, SSR3 password-read-protected.

FAQ

What is the purpose of the SSR0–SSR3 regions in the OTP array?

SSR0–SSR3 are four independent 512-byte lockable regions within the 2048-byte OTP array. SSR0 is factory-locked and permanently read-only; SSR3 supports password-based read protection. These regions store immutable calibration data, cryptographic keys, or boot configuration parameters that must resist tampering or accidental overwrite during field operation.

Does S29GL01GT10GHI010 support both ×8 and ×16 bus widths simultaneously?

No - the device operates in either ×8 or ×16 mode, selected at power-on via the BYTE# pin state. When BYTE# is low, it configures for ×16 data bus (DQ0–DQ15 active); when high, it enables ×8 mode (DQ0–DQ7 only). The mode is fixed per power cycle and cannot be dynamically switched during operation.

How does the suspend/resume feature function during sector erase?

During a sector erase (typically 245 ms), issuing the Erase Suspend command halts the erase operation and places the device in read mode. Host can then execute up to 100 μs of reads before resuming erase with Resume command. This avoids system stalls in real-time applications where interrupt latency must remain bounded.

Is the 100 ns random access time guaranteed across all temperature grades?

Yes - 100 ns maximum tACC is specified for the Industrial (–40°C to +85°C) and Automotive Grade 3 (–40°C to +85°C) variants. At +105°C (Industrial Plus/Automotive Grade 2), tACC increases to 110 ns; at +125°C (Extended), it is 120 ns - all values are fully characterized and guaranteed in the datasheet's AC specifications table.
