KAGA FEI Unveils Upcoming BLE Modules Set for Early 2026 Release

Key Takeaways

KAGA FEI is launching two new Bluetooth Low Energy modules, EC4L10BA1 and EC4L05BA1, enhancing its lineup.
The new modules support Bluetooth 6 and carry PSA Level 3 security certification, making them suitable for secure IoT applications.
Mass production is set to begin in January 2026, with initial samples available in October 2025.

KAGA FEI Expands Bluetooth Module Lineup

KAGA FEI, formerly known as Fujitsu Electronics America, is broadening its Bluetooth Low Energy (BLE) module offerings with the introduction of two new products: the EC4L10BA1 and the EC4L05BA1. These new modules complement the existing EC4L15BA1 model and come with a variety of memory capacities designed to cater to diverse application needs, from healthcare to industrial IoT.

Both the EC4L10BA1 and the EC4L05BA1 modules boast built-in antennas for reliable performance and support Bluetooth 6—a standard that enhances data transfer capabilities and connectivity. The on-board chipset in these modules has achieved PSA Level 1 certification, which signifies compliance with a robust security framework tailored for the IoT sector, ensuring that connected devices operate safely and reliably.

Memory specifications for the modules include:
– EC4L15BA1: 1.5MB NVM and 256KB RAM
– EC4L10BA1: 1.0MB NVM and 192KB RAM
– EC4L05BA1: 0.5MB NVM and 96KB RAM

The modules are certified at PSA Level 3, which is the highest security level in the IoT landscape, and are officially qualified by Bluetooth SIG for Bluetooth 6. This security is particularly critical as vulnerabilities in Bluetooth modules have increasingly become targets for cyberattacks, especially within the growing network of IIoT devices connected to TCP/IP networks. Recent advisories have highlighted security flaws in technologies such as OpenSynergy’s BlueSDK and the Realtek RTL8762E, necessitating robust security measures in new devices.

In addition to Bluetooth Low Energy, the new modules are compatible with the Matter Standard and Thread, enabling communication speeds of up to 4Mbps. The support for Channel Sounding technology allows for accurate distance measurement between devices, further enhancing performance in IoT applications.

The built-in antennas of the EC4L10BA1 and EC4L05BA1 have received pre-certifications from regulatory bodies including the FCC in the USA, Japan’s Radio Law MIC, and Canada’s ISED. This streamlines integration into existing devices.

KAGA FEI plans to release the first samples of these modules in October 2025, with mass production expected to commence in January 2026. This expansion reflects the company’s commitment to advancing IoT technology and ensuring the security and reliability of connected devices in various sectors.
