Jul
2019
Climate change is upon us, with an avalanche of new MCU coming from the Grenoble region in France in the middle of the summer… ST has released no less than 100 new STM32G4xxx products, and also a multicore Cortex-M7+Cortex-M4, impressive. IFX is acquiring Cypress semiconductor to secure its stronghold in the automotive market. Enjoy the wild ride.
No change.
Infineon follows their strategy of small protfolio of targeted products. The XMCXXXXSC devices are members of the XMC1000 Family of microcontrollers based on the ARM Cortex-M0 processor core. The XMCXXXXSC series addresses the real-time control needs of wireless power systems. The XMC6521SC-Q040X is a Qi single coil 15W inductive MP-A11 desktop transmitter.
Ah, also, Infineon is set to acquire Cypress, below…
There were a few updates, and an interesting option for the ATSAM11, the Securely Key Provisioned (KPH extension) with the key being provisioned using Root of Trust flow. The
Security Software Framework uses Kinibi-M™ Software Development Kit (SDK).
No change.

No significant change.
Renesas added more to its portfolio of RX72T, a 32-bit RXv3 based MCU optimized for motor control applications. It also launched the RX72M Group, focused on industrial network solutions, with 16 products. The RX72M Group uses the RXv3 core at 240MHz with double-precision FP, an EtherCAT slave and Flash/SRAM up to 4MB/1MB. The group also supports up to WVGA TFT LCD display.
No change this month after the launch of the Gecko 2 earlier this year.
Cypress continues to move its part names to its standard CYxxxx nomenclature. Well, expect more part name changes as the acquisition of Cypress by Infineon nears completion.
What a month, with no less than 174 new products on the ST website. Let’s decompose…
ST launched the STM32G4, focused on mixed signal with DSP and FPU instructions.
The series runs a Cortex-M4 at 170 MHz and hardware accelerators: ART, CCM-SRAM routine booster and math accelerators. It adds analog peripherals (comparator, op-amps, DAC) a 16-bit ADC, a High-resolution timer, USB-C with Power Delivery + PHY and AES hardware encryption.
The series splits into 3 product lines:
- STM32G4x1 Access line: GP MCU with an entry level set of analog peripherals
- STM32G4x3 Performance line: GP MCU with enhanced analog peripherals
- STM32G4x4 Hi-resolution line: high-resolution timer (184ps) and complex waveform builder plus event handler (HRTIM) for digital power conversion, such as digital switched-mode power supplies, lighting, welding, solar and wireless charging
Package options are LQPF32/48/64/80/100/128, UFBGA100, WLCSP64/81, UQFN32/48 for devices with 32 up to 512 Kbytes of Flash memory. Prices start right below $2 @ 10k (STM32G431K8T6)
and temperature range spans from -40 to +85C or +125C.
It reminds us of the Renesas RX72T that was announced last month with a very similar set of peripherals, including the high resolution timer to tackle precision digital control.
ST allow muscled up its STM32H7 series with the addition of 55 new products. A few sprinkles for the H742/3, mostly tray and packages variations appeared. But we got to see the new H745/H755 (+crypto) twins that incorporate a 240MHz Cortex-M4 core on top of the 480MHz Cortex-M7! Now, throw in a MIPI-DSI interface into the mix and you have the H747/H757. Engineers will have fun programming these beasts, powering new graphic applications.
No significant change this month.
More ARM v8-M with Nuvoton’s new M26x
01
Jun
2019
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.
The STM32H74x is getting a no-graphics acceleration version, the STM32H742. Frequencies were increased for the STM32H7 from 400MHz to 480MHz too.
No significant change this month.
