Renesas releases the DA14592, a new dual-core Cortex-M33/M0+ BLE chip with integrated flash

The DA14592 System-on-Chip (Soc) is Renesas’ “lowest power consumption and smallest, multi-core Bluetooth LE device.” According to the company, this chip’s design was achieved by making careful tradeoffs between on-chip memory and die size. The chip offers an ultra-low power mode that uses only 2.3mA when transmitting radio signals at 0dBm and consumes 1.2mA to receive radio signals. It also supports a hibernation mode that uses about 90nA and can extend the operating life of battery-powered products. The active mode is best for processing-intensive products and uses 34µA for every MHz of CPU clock. Projected key applications for the DA14592 chip include crowd-sourced location (CSL) tracking as used in Apple’s Airtags, remote control units, human interface devices, asset tracking, IoT end nodes, data logging, connected health, and activity tracking. Renesas DA14592 specifications: CPU cores: Cortex-M33F running at up to 64MHz as application core Cortex-M0+ at 64MHz as configurable MAC Memory: […]

LILYGO T-Panel – A 4-inch HMI display and WiFi, BLE, and 802.15.4 gateway based on ESP32-S3 and ESP32-H2

T-Panel 4-inch ESP32-S3 and ESP32-H2 gateway

LILYGO T-Panel is both a 4-inch HMI display and IoT gateway based on ESP32-S3 WiFi 4 and Bluetooth LE 5 microcontroller and an ESP32-H2 module with Bluetooth LE 5 and an 802.15.4 radio for Zigbee, Thread, and Matter connectivity. Last year, Espressif introduced the ESP-Thread Board Router/Zigbee gateway board with ESP32-S3 and ESP32-H2 to show how both chips could be combined to create IoT gateways. But I don’t think I had seen a company design a product based on both ESP32-S3 and ESP32-H2 until I saw the T-Panel which also includes an RS485 interface and Qwiic expansion connectors for good measure. T-Panel specifications: Wireless chips/modules Wireless SoC – ESP32-S3R8 dual-core Tensilica LX7 microcontroller @ 240 MHz 2.4 GHz 802.11n WiFi 4 and Bluetooth 5.0 LE connectivity Memory – 8MB PSRAM Wireless module – ESP32-H2-MINI-1 module MCU – Espressif Systems ESP32-H2 32-bit RISC-V microcontroller at up to 96 MHz with 320 […]
