Infineon Technologies S70GL02GT12FHIV10

Overview

S70GL02GT12FHIV10 from Infineon is a 2 Gb (256 MB) parallel NOR flash memory IC built on 45 nm MIRRORBIT™ process, featuring 110 ns random access time, 20 ns page access time, and 512-byte programming buffer. It integrates two 1024 Mb S29GL01GT dies in a single 64-ball fortified-BGA package and supports industrial (–40°C to +85°C) and automotive AEC-Q100 grade 3 operation for embedded boot code storage.

For engineers reviewing the S70GL02GT12FHIV10 datasheet, S70GL02GT12FHIV10 pinout, S70GL02GT12FHIV10 application, or S70GL02GT12FHIV10 equivalent, key selection criteria include uniform 128-KB sector erase architecture, dual-die stack configuration, VIO range of 1.65 V to VCC, OTP array with two lockable regions, and hardware write protection via WP#.

Technical Context

This device implements a dual-die stacked architecture where two S29GL01GT dies share common control signals (CE#, OE#, WE#, RY/BY#, RESET#) and operate as a unified 2 Gb memory space. Address lines A0–A26 support full 256 MB addressing with byte/word mode selection via BYTE#.

It uses Common Flash Interface (CFI) for standardized identification and supports three status monitoring methods: Status Register polling, data polling, and open-drain RY/BY# output. Sector protection includes volatile/non-volatile ASP and dedicated WP#-controlled lock on the highest 128-KB sector.

FAQ

What is the function of the RY/BY# pin, and how must it be interfaced?

RY/BY# is an open-drain ready/busy indicator that pulls low during active program/erase operations and floats high-impedance when idle. It requires an external pull-up resistor (typically 4.7 kΩ to VIO) to detect the ready state. Multiple devices can share a single RY/BY# line for synchronized status monitoring in multi-chip configurations.

How does the BYTE# pin affect data bus configuration and address mapping?

When BYTE# is driven low, the device operates in ×8 mode: DQ7–DQ0 become active data lines, and DQ15/A-1 functions as the LSB address input (A0). In ×16 mode (BYTE# = high), DQ15–DQ0 serve as the full data bus, and all 16 bits transfer simultaneously. This dual-mode flexibility supports legacy 8-bit microcontrollers and modern 16-bit bus architectures.

Can the WP# pin protect sectors other than the highest 128 KB?

No - WP# exclusively protects the highest-address 128 KB sector (SA2047). Other sectors require software-controlled Advanced Sector Protection (ASP) using command sequences written to the command register. ASP supports both volatile (power-loss reset) and non-volatile (persistent) locking per sector, independent of WP# state.

What is the purpose of the OTP array, and how is it secured?

The 1024-byte OTP array contains two independently lockable regions used for storing immutable data such as cryptographic keys, calibration coefficients, or device serial numbers. Each region is locked permanently via dedicated CFI commands; once locked, its contents cannot be erased or rewritten, ensuring tamper-resistant storage for security-critical parameters.
