Nuvoton adds Ethernet and CAN FD to its Cortex-M product porfolio




As we are leaving the scorching summer, Nuvonton continues to hack at their Cortex-M product portfolio with this time a focus on secure MCUs based on the M4 with either Ethernet MAC or CAN FD and USB. We were checking on the MCX products from NXP announced in June, unfortunately no products yet.

Only minor changes in the CY8C41xx families this month.
There were less than 30 new parts with the PIC18Fx6 taking the lion’s share.
No change.
Nuvoton launched the new M463 and M467.
The M467 Ethernet/Crypto series is based on a 200 MHz Cortex-M4 core and features 1.7/3.6 V operating voltage, with -40°C/+85°C temperature range and ESD immunity with HBM 2 KV and EFT 4.4 KV. It provides up to 1024 kB dual bank of Flash memory and 512 KB SRAM for run time operation. The dual bank Flash memory design supports Firmware Over-The-Air (FOTA) process. Additionally, the M467 series supports Execute-Only-Memory (XOM) function to protect confidential code.
The M467 Ethernet/Crypto series interface support includes Ethernet 10/100 MAC, hardware crypto engine, Key Store, true random number generator (TRNG), programmable audio PLL, HyperBus interface (HBI), 4 sets of CAN FD, USB HS OTG, USB FS OTG, up to 24 channels of 16-bit PWM, 10 sets of UART, 4 sets of SPI/I2S, 2 set of Quad-SPI, 5 sets of I²C, and a real-time clock (RTC). On the analog front, the series also provides 4 sets of analog comparators, up to 28 channels of 12-bit SAR ADC, and 2 channel of 12-bit DAC.
The M463 CAN FD/USB HS borrows the same features as the M467 and extends the temperature to -40°C/105°C, but only supports 256kB flash and 128 kB RAM. Peripheral support is also different: hardware crypto engine, key store, true random number generator (TRNG), 2 sets of CAN FD, USB HS OTG, up to 24 channels of 16-bit PWM, 8 sets of UART, 4 sets of SPI/I2S, 2 set of Quad-SPI, 5 sets of I²C, and a real-time clock (RTC). On the analog front, the M463 includes 2 sets of analog comparators, up to 16 channels of 12-bit SAR ADC.
4 part numbers were released for each series.

No change this month. Here is a recap of a major change announced during the summer:
Apart from a few variants for the i.MXRT106x (package) and i.MX6x (without ethernet), NXP announced a new product portfolio, the MCX.
The message is centered on the intelligent edge: secure products that can carry complex functions close to the sensors.
NXP also touts the first instantiation of NXP’s new, specialized neural processing unit (NPU) for accelerating inference at the edge.
The Cortex-M33-based portfolio seem to cover a vast array of markets and use cases. Frequencies range from 32 to 250MHz with up to 4MB/1MB of Flash/RAM. 4 series of devices use the same tools (including the company’s MCUXpresso) and software foundations:

  • MCX N Advanced series: designed for secure, intelligent applications, with families that include an integrated EdgeLock® secure subsystem and dedicated NPU for real-time inference. This will likely be the top of the line series, with abundant peripherals and memory.
  • MCX A Essential series: optimized to provide critical functionality for a broad range of applications where cost constraints and time to market are key considerations. This series will likely offer a large portfolio of general-purpose devices.
  • MCX W Wireless series: offers low-power narrowband connectivity, including BLE. Designed to simplify adding wireless connectivity to IoT devices, its energy-efficient radio helps extend the battery life of small connected systems.There doesn’t seem to be a differentiating feature, beyond the Cortex-M33 which the other NXP wireless products don’t have.
  • MCX L Ultra-Low Power series: designed for power-critical applications. With one of the industry’s lowest dynamic power consumption offerings, these devices can help extend battery life significantly compared to traditional MCUs. We will have to see when we get the power numbers…

No timeline nor products have been announced yet, we will have to wait an additional few months (quarters?) to get the details.

There were new revisions of existing part numbers in the RL78 family, revisions are marked with the #00/#10/#15 suffixes.
No significant change.
ST Microelectronics
ST was quiet this month.
