Nuvoton on fire!

Nuvoton has been the ruler this time with no less than a new Cortex-M7 family, a slew of Cortex-M23 and more Cortex-M0 based parts. NXP is pushing the “low” side of the i.MNXRT with a 200MHz Cortex-M33 but with an additional DSP and GPU, it will be enough to power nice user interfaces. Microchp has revamped its parametric search and in the process made 400+ parts orphans. Please contact us to get the list ;)
Dialog got acquired by Renesas in February, no change to the portfolio.
No change yet, before the merge storm with Cypress. We are seeing more links between the 2 websites, and we assume this will last a little while.
Microchip has made some changes to their web site and in the process has lost a few hundred parts that are now orphans, i.e. pages are found through the search bar, but do not appear in the parametrics search. An example? ATSAME51G19, found here but not in the parametric search.
Unless we have missed it? Don’t hesitate to contact us if we did.
For some reason the nRF51822 page is now orphan, will it dissapear from the Nordic site?
Contact us if we have missed it.
Nuvoton is doubling down on the Cortex-M23 and more… The Cortex-M23 M254/M256/M258 series comes with COM/SEG LCD display driver and capacitive touch key functions, an USB 2.0 FS device, runs up to 48 MHz and features up to 256/32 kB Flash/RAM with an operating voltage of 1.75V ~ 5.5V and -40 to +105C operating temperature.
Supported packages include LQFP44, LQFP64, LQFP80 and LQFP128, pin-compatible with the M251/M252, M031 and M480 series.
The Cortex-M7 based KM1M7 runs at 160MHz to support motor control / digital power supply control.
Finally, the Cortex-M0-based M030G/M031G series includes h 32-bit hardware multiplier/divider and runs up to 48/72 MHz with 64 Kbytes Flash, 4 Kbytes and 8 Kbytes SRAM, 2.7V ~ 3.6V operating voltage, 5V I/O tolerant, and -40°C to +105°C operating temperature.
Designed for Optical Transceiver Module applications, both of the M030G and the M031G series have a built-in temperature sensor with ±2°C deviation from -40°C to 105°C and 2 sets of strong I2C with 1MHz slave mode and non-stretch mode. Furthermore, the M031G series, which supports Pilot Tone Modulation, is equipped with a Hardware Manchester Codec with CRC to encode and decode low-frequency dither signal and 1 set of DAC with “Auto Data Generation” function to generate the smooth sine waveform up to 500KHz for the output of Pilot Tone Modulation.
In order to fit the small form factor requirement of the optical module, the M030G and M031G series provide the QFN 24-pin (3×3 mm) and QFN 33-pin (4×4 mm) small form factor package with pin-compatible across these 2 series to make the system design and change parts easily.
NXP added more options at the lower end of the spectrum to i.MXRT with the single core RT500 (Cortex-M33 200 MHz + Tensilica Fusion DSP 200MHz + 2D GPU). Features include:
- Flashless, with Quad and Octo SPI interfaces and on the fly decryption
- Up to 5MB of SRAM
- Advanced security, including secure boot and crypto engines
- USB HS, eMMC
- 2D GPU
- MIPI® DSI
Renesas dropped the HWQFN package for the RX110, and RX111 while adding new variants in the RX23E, RX66 and RX72 groups.
The SiM3x has been retired as it is NRND on the SiLabs site.
Cypress/Infineon released 19 new parts, mostly variants of existing parts.
ST had 33 new parts, again mostly variants, with higher temperatures for the STM32G051
TI only had a few minor variants this month.
a good cocktail for the summer time

Summer is here with a good cocktail of new products. NXP, Nuvoton, Renesas, Cypress and ST led the changes this month. There was a variety of new parts, from the high performance (600 MHz Cortex-M7 + Cortex-M4) i.MXRT to ST shooting for the low end with the STM32G05x, Renesas and Cypress/Infineon with motor control and Nuvoton pushing hard on the Cortex-M23.
Dialog got acquired by Renesas in February, no change to the portfolio.
No change yet, before the merge storm with Cypress. We are seeing more links between the 2 websites, and we assume this will last a little while.
Microchip has about 100 new parts, variants of existing ones.
No change.
Nuvoton launched their M253 family with 3 parts.
It is based on a 48 MHz Cortex-M23 with up to 128 Kbytes Flash, 16 Kbytets SRAM, 1.75V ~ 5.5V wide operating voltage, and -40°C to +105°C operating temperature. It includes a crystal-less USB 2.0 full speed device and one set of CAN FD interface for industrial automation and automotive related applications.
The M253 series provides up to 5 sets of UART, 2 sets of I²C, 1 set of SPI/I2S and Universal Serial Control Interface (USCI). It also includes a 12-channel/12-bit 880 kSPS ADC, 6 channels of 16-bit PWM.
Two types of packages are available, QFN33 5×5 and LQFP48 7×7, both are pin-compatible to M251/M252, M031 and M480 series.
NXP added more options to to the i.MXRT with the dual core RT1160 (Cortex-M7 600 MHz + Cortex-M4 240 MHz). Features include:
- 1 MB SRAM with 512 KB of TCM for Cortex-M7 and 256 KB of TCM for Cortex-M4
- Advanced security, including secure boot and crypto engines
- 1 Gbps ENET w/ AVB + 10/100 ENET w/ IEEE 1588
- 2D GPU
- MIPI® CSI/DSI
Renesas beefed up the RL78/G1M and RL78/G1N/G1P, respectively
a small pin-count 20-pin package, with real-time output terminals for motor drive. It has 120-degree energization control and can drive a BLDC motor,
an 8-bit general-purpose microcontroller equipped with large current output terminals for driving LEDs. It allows direct drive of 8-segment 6-digit high brightness LEDs,
a 32MHz microcontrollers with a 10-bit D/A and a 12-bit A/D converters.
No change.
Cypress/Infineon released 80 new parts, mostly variants of existing parts. The CY8C4147 is new with double the frequency of the CY8C4128 with similar peripherals. We also saw the first PSoC 4500S parts based on a 48-MHz Cortex-M0+, targetting motor and power control. These adds compute capability in the form of divide and square-root accelerators, but also dual 12-bits ADCs for motor control and power conversion.
ST had 40 new parts, with an interesting STM32G05x/06x. The new STM32G050 Value Line and mainstream STM32G051 and STM32G061 MCUs add analog features and up to 18KBytes of RAM, with package options up to 48-pins. In addition, the STM32G0B0 Value Line, STM32G0B1 and STM32G0C1 MCUs introduce new features to the STM32G0 series by integrating a USB 2.0 device/host controller and dual-bank Flash memory. The STM32G0B1 and STM32G0C1 feature ST’s FDCAN peripheral.
The new STM32G0 devices are in production now, priced from $0.47 for the STM32G050F6P6 Value Line in TSSOP20 with 32KBytes Flash. The STM32G0B product line begins at $1.21 for the STM32G0B0KET6 in LQFP32 with 512KBytes Flash for orders of 10000 pieces.
TI only had a few minor variants this month.
