Infineon Technologies S70GL02GS12FHIV20

Overview

S70GL02GS12FHIV20 from Infineon is a 2 Gbit (256 MB) parallel NOR flash memory device fabricated on 65-nm MIRRORBIT™ technology, featuring 128-KB uniform sectors, 110 ns random access time, and 25 ns page access time. It operates from a single 2.7–3.6 V supply with Versatile I/O supporting 1.65–VCC VIO, and integrates dual S29GL01GS die in one package for embedded boot code storage in automotive instrument clusters.

For engineers reviewing the S70GL02GS12FHIV20 datasheet, S70GL02GS12FHIV20 pinout, S70GL02GS12FHIV20 application, or S70GL02GS12FHIV20 equivalent, key selection criteria include sector erase endurance (100,000 cycles), industrial/automotive temperature support (–40°C to +105°C), OTP array availability, CFI compliance, and Fortified-BGA mechanical robustness for high-reliability PCB layouts.

Technical Context

This device implements a dual-die stack architecture-two independent 1-Gb S29GL01GS dies sharing address/data bus and control signals-with external A26 used to select between top and bottom die. Sector erase and buffer programming are executed per-die, requiring explicit die selection before operation.

The memory supports three protection modes: hardware WP#-based outer-sector lock, volatile/non-volatile Advanced Sector Protection (ASP), and a dedicated 1024-byte OTP array split into two lockable regions. Status monitoring uses Ready/Busy pin, data polling, and Status Register reads.

FAQ

What is the function of the A26 pin on S70GL02GS12FHIV20?

A26 serves as the die-select signal: when low, it accesses the lower 1-Gb die; when high, it selects the upper 1-Gb die. This enables full 2-Gb addressing across the dual-die stack while maintaining JEDEC-compatible command sets per die. The pin must be driven externally and is not internally decoded.

Does S70GL02GS12FHIV20 support execute-in-place (XIP) operation?

Yes, it supports XIP via its ×16 parallel interface and fast 25 ns page access time, allowing microcontrollers to execute code directly from flash without copying to RAM. The 16-word read buffer and low-latency random access (110 ns) make it suitable for real-time deterministic boot and UI rendering.

How is the 1024-byte OTP array structured and accessed?

The OTP array consists of two 512-byte lockable regions, each programmable once and permanently secured via dedicated lock bits. Access occurs through standard CFI commands and specific address ranges (0x0000_0000–0x0000_03FF); once locked, regions cannot be reprogrammed or erased, ensuring cryptographic key immutability.

Can S70GL02GS12FHIV20 operate with VIO = 1.8 V while VCC = 3.3 V?

Yes, the Versatile I/O feature explicitly supports VIO from 1.65 V to VCC, so 1.8 V I/O with 3.3 V core is fully compliant. This allows direct connection to 1.8 V FPGA or ASIC interfaces without level shifters, reducing BOM count and signal integrity risk in mixed-voltage systems.
