30
Sep
2023
SiLabs continues to provide innovative solutions for the IoT market with, this month, a radio co-processor optimized for gateways, hubs and access points for the BLE and Zigbee protocols in the 2.4 GHz band.
Renesas added a new group to the RL78 with an embedded “Flexible Application Accelerator”. The new RL78/G24 group targets motor control, power supply, and lighting applications.

Nuvoton
Nuvoton released high temperature versions for the M467 Ethernet/Crypto series. It is a 32-bit microcontroller based on Arm Cortex-M4F core, with DSP instruction set and single-precision floating-point unit (FPU), targeted for IoT gateway, industrial control, telecom, and data center applications. The M467 Ethernet/Crypto series runs up to 200 MHz, and features 1.7 V to 3.6 V wide operating voltage.

Renesas
Renesas released 88 new products in the RL78 family in particular into the existing RL78/G23 and the new group RL78/G24.
The RL78/G24 group has the highest processing performance of the RL78 family of MCUs, with a CPU operating frequency up to 48 MHz and a flexible application accelerator (FAA). In addition, the enhanced analog functions and timers make it a good fit for motor control, power supply, and lighting applications. The FAA is a co-processor dedicated to arithmetic operations, and can be operated independently of the CPU, delivering higher processing power.
Main features include:

SiliconLabs
The EM35x got EOLed, and a couple of interesting products were introduced:
The EFR32BG24B310F1536IJ42 with a CSP package is focused on BLE connectivity for clinical and portable medical, smart home, and lighting devices. It has received the highest PSA Certification Level 3 security. It features a Cortex-M33 core with 1536 kB Flash, 256 kB of RAM and 20 GPIO.
The EFR32MR21A020F512IM32 on the other side, is a wireless RCP (Radio Co-Processor) device that has been optimized for gateways, hubs, and access points. Based on the MG21 family, the MR21 runs the PHY/MAC for 802.15.4 and up to the HCI interface for Bluetooth Low Energy. For products that already have a separate host MCU or MPU, the RCP device enables lower hardware cost by reducing the requirements of the wireless IC and allowing the wireless protocol and application to run on the existing host MCU/MPU. The MR21 device includes 512 Flash, 64 RAM and is available in a QFN32 package. With +20 dBm maximum power output and excellent receive sensitivity the EFR32MR21A020F512IM32 provides a robust RF link for reliable communications.

On the EFM32 front, SiLabs released 4 new products to create the EFM32PG28 family. It is based on an 80 MHz Cortex M33 with LCD controller. It is a sister MCU to the EFR32xG28 wireless SoC platform (ZG28, FG28 and SG28). The PG28 is also the first EFM32 device with a hardware AI/ML accelerator allowing for faster inferencing at the edge with lower power consumption.
And on the wireless side, it released another 23 products across 2 families, the EFR32SG2x and the EFR32FG28.
The EFR32SG23 is a secure wireless SoC for Amazon Sidewalk devices that supports sub-GHz FSK, providing range beyond the front door to cover detached buildings, pools, and spas. The multi-core device has an ARM Cortex-M33 running up to 78 MHz and with 512 kB of Flash and 64 kB of RAM. It targets battery operated end devices like sensors including door, window, and temperature sensors devices.
The big brother EFR32SG28 bumps up the Flash/RAM sizes to 1MB/256kB.
The EFR32FG28 takes the same digital architecture but supports both sub-GHz and 2.4GHz to add Bluetooth.
Overall, 23 products were released.
