Renesas RZ/T2H Cortex-A55/R52 industrial MPU and Dev Board support EtherCAT, PROFINET, and TSN

Renesas RZ/T2H industrial MPU is the most powerful member of its RZ/T2 series of real-time microprocessors. The MPU features four Arm Cortex-A55 CPUs for application tasks and two Cortex-R52 CPUs for real-time control. It supports 9-axis motor control with 3-phase PWM timers, delta-sigma interfaces, and encoder interfaces. It also supports Industrial Ethernet protocols like EtherCAT, PROFINET, and TSN. These features make it ideal for industrial applications such as industrial robots, PLCs, motion controllers, and CNC machines. Renesas launched the RZ/T2L single-core Arm Cortex-R52 MPU just last year, and before that, in 2022, they launched the RZ/T2M dual Arm Cortex-R52 MPU. The RZ/T2L was just a cost-down version of RZ/T2M with an EtherCAT controller, compared to those old controllers the latest RZ/T2H supports 9-axis motor control and compatibility with various industrial Ethernet protocols. Renesas RZ/T2H specifications: CPU 4x Arm Cortex-A55 (64-bit) clocked at up to 1.2GHz with 32KB L1 I/D cache, 1MB L3 cache 2x […]

Conexio Stratus Pro nRF9151 low-power IoT development kit supports LTE-M/NB-IoT, DECT NR+, GPS, and more

Conexio Stratus Pro nRF9151 is an IoT development kit based on Nordic Semi nRF9151 system-in-package (SiP) with LTE-M/NB-IoT, DECT NR+, and GNSS connectivity designed for battery-powered cellular-connected products such as asset trackers, environmental monitors, smart meters, and industrial automation devices. It’s offered with the “Stratus Pro Expansion Dock” allowing users to add WiFi 6 through an nRF7002 expansion board and various other modules via Grove, Qwiic, MikroBus, and Seeed Studio’s XIAO connectors or sockets. It’s an update to the original Conexio Stratus Pro based on nRF9161 introduced last June with a very similar feature set. Let’s have a deeper look to find out any potential differences between the two versions of the devkit. Conexio Stratus Pro nRF9151 specifications (with changes highlighted in bold or strikethrough): System-in-package – Nordic Semi nRF9151 SiP MCU – Arm Cortex-M33 clocked at 64 MHz with 1 MB Flash pre-programmed MCUBoot bootloader, 256 KB RAM Modem […]

NXP RW612 Arm Cortex-M33 Wireless MCU offers Wi-Fi 6, Bluetooth 5.4, and 802.15.4 radios

The NXP RW612 is an Arm Cortex-M33 SoC with three radios, namely WiFi 6, Bluetooth 5.4, and 802.15.4 for Thread and Matter connectivity. It also has a small sibling called the RW610 without the 802.15.4 radio. I first came across RW61x chips, when Debashis wrote about the Trimension SR250 UWB chip mentioning it can work with “host processors like NXP’s i.MX, RW61x, and MCX families”. I initially thought it was a typo for the iW612 tri-radio solution introduced in 2022, and the RW612 is indeed similar, but it’s a complete wireless microcontroller/SoC with an Arm Cortex-M33 application core so it can be used independently as a host instead of a companion chip. NXP RW612 and RW610 specifications: MCU sub-system Core – 260 MHz Arm Cortex-M33 with TrustZone-M Memory On-chip 1.2 MB SRAM PSRAM interface for memory expansion Storage – Quad FlexSPI Flash XIP with on-the-fly decryption Peripheral interfaces Up to […]
