More ARM v8-M with Nuvoton’s new M26x




Nuvoton released more Cortex-M23 based MCUs, the M26x series with 9 part numbers. NXP uncovered the NxH3670, a Cortex-M0 BT4.2 MCU with a proprietary audio streaming extension. Interestingly, it targets the gaming headset. Did not know that what seems a pretty narrow application could drive the creation of a dedicated MCU. Ah, and Renesas is beefing up the RX72T with more RXv3-core based MCU.

No change.
No change.
There was a large contingent of new parts this month, over 200. A third was for the ATSAMD21 getting higher temperature (+125C) versions of existing parts and the majority of the rest focused on new SOIC packages for the PIC16.
No change.
Nuvoton just launched the NuMicro® M26x series with 9 parts, all based on the Cortex-M23 core, 64MHz/512KB Flash supporting Over-The-Air ( OTA ) firmware update and 96 Kbytes embedded SRAM. Power supply is 1.8 ~ 3.6V with a temp range of -40 to +105 ℃.

Nuvonton claims 97 μA / MHz ( LDO mode ) and 45 μA / MHz ( DC-DC mode ) in normal run mode, 2.8 μA in Standby Power-down mode, and less than 2μA in Deep Power-down mode without VBAT. It comes with secure boot and a 4-region programable eXecute-Only-Memory ( XOM ) to secure critical program codes. AES 256/192/128 accelerator and True Random Number Generator are built-in for data encryption. On the peripheral side, the M26x comes with SDHC V2.0, Quad-SPI.
The M262 adds a crystall-less USB 2.0 FS OTG transceiver to the M261

The M263 adds one set of CAN 2.0B controllers, compared to the M262.

The NuMicro® M261 series are suitable for classic IoT node devices, NuMicro® M262 series are suitable for connecting to USB host / device for data transfer, NuMicro® M263 series are suitable for industrial and automotive application that required CAN Bus for data communication.

Packages include QFN33 ( 5 mm x 5 mm ), LQFP64 ( 7 mm x 7 mm) and LQFP128 ( 14 mm x 14 mm ).

NXP launched the NxH3670, a single-chip 2.4 GHz wireless transceiver with a single core Cortex-M0, targeted at wireless audio streaming for gaming headsets at very low latency. It is certified for BTLE 4.2 with a proprietary audio streaming extension. TX output is −10 dBm to +4 dBm with a sensitivity of −90 dBm in BTLE 2 Mbps and −94 dBm@1Mbps. Current is < 4 mA for RX at 1.2V and < 7 mA for TX @0 dBm output power, all at 1.2V. The operating temperature is a weird -20°C +85°C. Well, who would be ga,ing at -20C anyways?
Renesas doubled its portfolio of RX72T, a 32-bit RXv3 based MCU optimized for motor control applications. The RX72T runs at 200 MHz (5.8 CoreMark/MHz) with 2.7 to 5.5 V and -40 to 105 °C operation, Flash/SRAM are up to 1MB/128KB. There is amd Arithmetic unit for trigonometric functions as well as 12-bit A/D Converter x 30 channels for 3 units , 12-bit D/A Converter x 2 channels, 6-channels of Comparators and 6-channels of Pseudo-Differential PGA, 4 channels for 3-phase complementary switching, 2 channels for 5-phase complementary switching, 10 channels for single-phase complementary switching, 4-channel high-resolution PWM enables minimum 195 ps timing adjustment and finally a Trusted Secure IP Lite (AES/TRNG) module.
No change this month after the launch last month of the Gecko 2.
Cypress continues to move its part names to its standard CYxxxx nomenclature.
ST Microelectronics
The STM32H74x is getting a no-graphics acceleration version, the STM32H742. Frequencies were increased for the STM32H7 from 400MHz to 480MHz too.
Texas Instruments
No significant change this month.
