Product Overview
The AT45DB321E-SHF-T, developed by Dialog Semiconductor (formerly Adesto), is a high-performance SPI serial Flash memory chip designed for low-power, high-reliability embedded systems. With 32Mbit (4MB) capacity, flexible memory architecture, and a wide voltage range, it is an ideal choice for IoT devices, industrial controls, consumer electronics, and more.
Key Features
High-Speed SPI Interface
- Supports SPI modes 0/3 with clock speeds up to 85MHz for rapid read/write operations.
- Compatible with standard SPI, Dual SPI, and Quad SPI modes for versatile host controller integration.
Low Power Consumption
- Active current as low as 4mA (read operation) and standby current of 25μA, extending battery life in portable devices.
Flexible Memory Architecture
- Page (528 bytes) and block (256 pages) erase capabilities for simplified data management.
- Dual independent buffers enable simultaneous read/write operations, boosting system efficiency.
Industrial-Grade Reliability
- Endurance: 100,000 erase/write cycles; data retention: 20 years.
- Operating temperature range: -40°C to +85°C, suitable for harsh environments.
Wide Voltage Support
- 2.3V to 3.6V power supply, compatible with mainstream embedded systems.
Typical Applications
- IoT Devices: Sensor data logging, firmware updates.
- Industrial Automation: Parameter storage for PLCs, event logging.
- Consumer Electronics: Smart wearables, printer consumables.
- Medical Devices: Data buffering in portable monitors.

+ —1.What is the flame retardant rating of the external (encapsulation) resin? >
- The flame retardant rating is UL94 V-0.
-
+ —2.The recommended voltage of the output capacitor is 25V. Is there a problem if 16V is used? >
- The output voltage should be set with at least a margin. In addition, the output capacitor also affects the output ripple voltage. In general, the ESR (equivalent series resistance value) increases as the capacitor withstand voltage decreases, and the final output ripple voltage increases. Please confirm that the output ripple voltage generated is within the allowable range. In addition, the allowable ripple current will be smaller, so choose a product that is equivalent to the allowable ripple current of the recommended capacitor.
-
+ —3.Some coil installation directions may cause ringing？ >
- In the self-excited oscillation mode, the switching frequency may change depending on the mounting direction of the coil, and if the switching frequency is in the audible frequency band, the vibration of the coil may be heard. In addition, different installation positions may cause resonance with the installed circuit board, so the installation direction and position (including ringing) need to be discussed.
