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.
