What are the key features of BLUENRG-MSCSA?
- Upgradable BLE network processor with firmware update capability allowing stack version upgrades over-the-air without hardware redesign
- Ultra-compact WLCSP34 package measuring only 2.66 x 2.56 mm enabling BLE integration in miniaturized wearable and medical sensor designs
- Extended industrial temperature range from -40°C to 85°C supports deployment in outdoor IoT nodes and light industrial wireless sensor applications
- SPI/UART host interface simplifies integration with any low-power MCU host, decoupling BLE protocol stack from the application processor
What is BLUENRG-MSCSA used for?
BLUENRG-MSCSA is designed for IoT edge nodes, wearable health monitors, and wireless sensor patches where BLE connectivity is required in a sub-3 mm x 3 mm footprint. As a network processor it offloads the BLE stack from the host MCU, reducing firmware complexity and power consumption in battery-operated devices. The industrial temperature rating makes it suitable for smart building sensor nodes, asset tracking tags, and connected industrial instruments operating in variable ambient conditions.

Frequently Asked Questions
What package does BLUENRG-MSCSA use and what board area does it require?
BLUENRG-MSCSA is housed in a WLCSP34 package measuring 2.66 mm x 2.56 mm, occupying under 7 mm² of PCB area. This wafer-level chip-scale footprint is among the smallest available for BLE network processors, enabling BLE integration in wearables and medical patches where space budgets are under 100 mm² total.
How does BLUENRG-MSCSA's network processor architecture reduce host MCU workload in BLE IoT designs?
BLUENRG-MSCSA runs the full BLE protocol stack internally and communicates with the host MCU via a 4-wire SPI or UART interface, exchanging HCI packets. This offloads all BLE timing, link management, and radio control from the host, allowing a simple 8-bit or 32-bit MCU to remain in deep sleep for 99% of the duty cycle while the BLUENRG-MSCSA handles BLE advertising periods as short as 20 ms.
Can BLUENRG-MSCSA be updated in the field without hardware replacement, and why does this matter for IoT deployments?
Yes. The upgradable firmware architecture of BLUENRG-MSCSA supports over-the-air (OTA) stack updates, allowing BLE specification compliance improvements and bug fixes to be deployed to thousands of field nodes without physical access. This is critical for IoT deployments where devices operate for 5 or more years across firmware revisions, reducing maintenance costs by millions of service visits in large-scale smart building or industrial monitoring networks.
