2025
Good activities on the Bluetooth front this month as Silicon Labs launched the EFR32BG26 series with BT5.4, PSA Level 3 security, and ML acceleration for low-power IoT. Renesas introduced the RA0E2, a Cortex-M23 MCU targeting cost-sensitive embedded control, adding to the already extensive RA group.

NXP
NXP had only minor changes this month. Remember the announcement of the MCX N23x last month:
It is based on a 150MHz Cortex-M33, with 1MB of Flash, 352 KB ECC RAM and SmartDMA.

The EdgeLock Secure Enclave on the MCX N23x is a self-contained, on-die hardware security subsystem that has its own dedicated security core, internal ROM, secure RAM and it supports state-of-the-art side-channel attack-resilient symmetric and asymmetric crypto accelerators and hashing functions for security services.
8 parts were released, prices start at $3.59/10k with 512/192 kB Flash/RAM and 100-pin HLQFP package.
Renesas
Renesas released the RA0E2 group, a basic, simple microcontroller (MCU) in the entry line of the RA0 series. It is a ROM/PIN extension product of the RA0E1 group, with which it is highly compatible. It is based on a 32MHz Cortex-M23 core with up to 128KB of embedded flash memory, 16KB SRAM, and a temperature range from -40 to 125°C. The RA0 series is ideal for cost-sensitive applications such as low power and lower cost for consumer electronics, system control for small appliances, industrial system control, and building automation.

SiliconLabs
The EFR32BG26 was launched with 18 products, for secure, high-performance IoT devices. Featuring a 78 MHz ARM Cortex-M33 core with up to 3.2 MB flash and 512 kB RAM, they support Bluetooth 5.4, including mesh networking, with output power up to +20 dBm for long-range connectivity.
All variants include Secure Vault™, providing advanced cryptographic protections (AES-128/256, ECC, SHA) and PSA/SESIP Level 3-ready security. Select models integrate a Matrix Vector Processor (MVP), enabling efficient on-device machine learning for tasks like sensor classification or keyword spotting—ideal for always-on, low-power applications.
The BG26 series is offered in compact QFN and high-pin-count BGA packages with up to 64 GPIOs, and supports ultra-low deep sleep currents, making it well-suited for wearables, medical monitors, smart locks, and industrial sensors.
Pricing ranges from $3.07 to $4.65 in 1k-unit volumes, depending on memory and package.
