I. SPI NOR Flash: The Preferred Choice for High-Performance Code Storage

GigaDevice SPI NOR flash is the core solution for code storage in embedded systems. Mainstream series such as the GD25 and GD55 offer capacities ranging from 512Kb to 2Gb, catering to diverse storage capacity requirements.

Key Advantages: Supports standard, dual, quad and octal SPI interfaces, with a maximum clock frequency of 200MHz and a data throughput of 400MB/s. It supports XIP (eXecute-in-Place), allowing direct execution without the need to load code, thereby significantly improving system response times.

Voltage and Power Consumption: Available in 3V, 1.8V, 1.2V and wide-voltage (1.65V–3.6V) versions. The 1.2V products in the GD25UF series consume 33%–70% less power than traditional 1.8V products, making them suitable for battery-powered devices.

Reliability: With a write endurance of 100,000 cycles and data retention of 20 years, along with an industrial-grade temperature range of -40°C to +85°C, these devices meet the requirements for long-term stable operation.

Typical models: GD25Q128ESIGR (128Mbit, SOP-8), GD25B127DSIGR (128Mbit, industrial grade).

II. SPI NAND Flash: High-Capacity, Low-Cost Storage Solutions

The GigaDevice GD5F series of SPI NAND flash memory is based on mature 38nm/24nm processes, with capacities ranging from 1Gb to 4Gb, balancing capacity, cost and performance.

Key Advantages: The SPI interface features a minimal pin count and compact packaging (e.g. WSON8), saving PCB space; an integrated 4-bit ECC error correction module supports hardware data protection, effectively mitigating the risks of power-off interference and data corruption.

Performance and Power Consumption: Supports high-speed SPI transmission with excellent read/write speeds, suitable for applications such as smart home logs, industrial equipment parameters, and IoT terminal data storage.

Reliability: Industrial-grade temperature range of -40°C to +85°C; automotive-grade versions extend to -40°C to +105°C; stable erase/write cycles; long-term supply guaranteed.

Typical models: GD5F2GQ5UEYIGR (2Gb, SPI NAND), GD5F4GM7UEYIGR (4Gb, high capacity).

III. Parallel NAND Flash: Traditional High-Bandwidth, High-Capacity Solutions

GigaDevice’s parallel NAND flash adheres to the ONFI protocol and utilises a parallel interface, offering high bandwidth, large capacity and exceptional stability, making it suitable for embedded systems with extremely high read/write speed requirements.

Key Advantages: Parallel data transfer with bandwidth far exceeding that of SPI interfaces, making it suitable for scenarios such as high-definition video storage, industrial automation data logging, and network device caching.

Process Technology and Capacity: Mature 38nm/24nm process technology, with capacities ranging from 1Gb to 8Gb, supporting multi-die stacking for capacity expansion to meet large-scale data storage requirements.

Reliability: Built-in ECC error correction, support for bad block management, and strong resistance to interference, making it suitable for complex industrial environments.

IV. Automotive-Grade Flash Memory: AEC-Q100 Certified, Safe and Reliable

GigaDevice’s automotive-grade flash memory, comprising automotive-grade SPI NOR (GD25/55 series) and automotive-grade SPI NAND (GD5F series), is fully AEC-Q100 certified. The GD25/55 series complies with the ISO 26262:2018 ASIL D functional safety standard.

Automotive-grade SPI NOR flash memory: capacities ranging from 2Mb to 2Gb, temperature grade 1 (-40°C to +125°C), supporting 3V/1.8V/1.2V voltages, data throughput of 400MB/s, with built-in ECC/CRC error correction, suitable for applications such as smart cockpits, ADAS domain controllers and vehicle gateways.

Automotive-grade SPI NAND flash: Capacity 1Gb–4Gb, temperature grade Grade 2 (–40°C to +105°C), built-in 4-bit ECC, supports PPAP/PSW files, meets the stringent quality requirements of the automotive OEM market.

Key Features: Targets a defect rate of 0 PPM, supports RPMC security functions, offers a write endurance of 100,000 cycles, and ensures data retention for 20 years; suitable for core systems in new energy vehicles and intelligent driving.
