BOYAMICRO
SPI NOR Flash memories for embedded systems, IoT and industrial electronics
About the manufacturer
BOYAMICRO is a brand of Zhuhai BOYA Technology Co., Ltd., a Chinese memory IC manufacturer focused primarily on non-volatile storage. Founded in Zhuhai in 2014, the company concentrates on the design, development and sale of memory devices used where firmware and data must remain available after power is removed.
A core part of the BOYA portfolio is serial NOR Flash with SPI interfaces. These devices are widely used to store firmware, boot code, configuration parameters, lookup tables, graphics and other resources required by embedded systems. The company moved NOR Flash products into volume production in 2016 and later expanded its portfolio to include EEPROM devices as well.
BOYAMICRO develops memory for consumer electronics as well as industrial control, communications, medical equipment, IoT and automotive-related applications. Important selection parameters include density, supply voltage, interface speed, operating temperature, package type, endurance and data-retention requirements.
Applications
BOYAMICRO memories are used wherever a device must retain program code or data when power is removed. Typical applications include:
- Embedded systems – storage of firmware, bootloaders and configuration data.
- IoT devices – memory for communication modules, gateways and edge devices.
- Industrial automation – controllers, I/O modules, HMIs and measurement equipment.
- Networking and telecommunications – firmware and system-configuration storage.
- Consumer electronics – smart devices, controllers, computer accessories and home electronics.
- Medical electronics – storage of configuration and operating data in diagnostic and monitoring equipment.
- Automotive systems – auxiliary non-volatile storage in electronic control modules, subject to the qualification of the specific series.
BOYAMICRO products available from Maritex
The BOYAMICRO range available from Maritex focuses on serial Flash memories for embedded systems and electronic devices that require non-volatile data storage.
Available product groups include:
- SPI NOR Flash memories.
- Flash devices in SMD SOP8 packages.
- Memories supporting extended operating-temperature ranges.
- Devices for firmware and configuration-data storage.
One example is the BY25Q128ASSIG / BY25Q128ASSIG-TR, a 128 Mbit SPI Flash memory operating from 1.8-3 V, rated for -40 to +85 deg. C and supplied in an SOP8 package. This type of device is well suited to program or data storage in compact embedded products.
When selecting a memory device, key parameters include density, supply voltage, supported SPI mode and frequency, operating-temperature range and package compatibility with the PCB design.
