ADESTO
DataFlash non-volatile memory and serial NOR Flash
About the manufacturer
Adesto Technologies was a US semiconductor company focused on low-power non-volatile memory and solutions for the Internet of Things and industrial automation. The brand became particularly well known for DataFlash memory designed for reliable data storage in embedded systems.
Adesto memories used serial interfaces, low pin counts and architectures intended to simplify data storage in microcontroller-based products. Typical uses include firmware, configuration data, event logs, measurement data and user-interface assets.
In 2020, Dialog Semiconductor announced the acquisition of Adesto, but now Dialog Semiconductor is a part of Renesas Electronics. The Adesto name nevertheless remains associated with many AT45/DataFlash devices still present in supply chains and existing electronic designs.
Applications
Adesto memories are used in devices that require reliable storage of firmware, configuration data and operating information. Serial interfaces and solutions designed for low power consumption make them particularly suitable for embedded systems, IoT devices and industrial electronics.
- Embedded systems – storage of firmware and configuration data.
- IoT and smart home – settings, event logs and device data.
- Industrial automation – process parameters and diagnostic records.
- Security systems – configuration and event-history storage.
- Measurement equipment – local storage of results and calibration data.
- Consumer electronics – UI assets, settings and update data.
- Low-power designs – non-volatile SPI memory paired with microcontrollers.
ADESTO products available from Maritex
The Adesto range available from Maritex includes serial NOR Flash devices from the DataFlash family for embedded, automation, IoT and consumer applications. The devices are available in common SMD packages and communicate through SPI.
Available product groups include:
- Serial NOR Flash memories.
- DataFlash devices with SPI interface.
- Memory capacities ranging from a few to several dozen megabits.
- SMD memories suitable for industrial temperature ranges.
The portfolio includes devices such as AT45DB041E, AT45DB081E, AT45DB161E and AT45DB321E. Variants differ in capacity, memory organisation, supply voltage and maximum interface speed, reaching up to 85 MHz in selected models.
When selecting a memory device, consider capacity, supply voltage, SPI clock rate, memory organisation, operating temperature, package type and software compatibility with the target controller or microcontroller.
