Fall mix

2024
There was a good mix of new products in September with NXP, ST and TI all releasing new Cortex-M parts. NXP boosted its M33 portfolio adding to the higher end while ST chose to protect the low cost STM32C0 with higher memory variants. TI is pushing the Cortex-M0+ to the automotive market, a move we haven’t seen – yet from ST.
No significant changes this month.
Microchip added about 50 products this month, mostly for the ATSAMC/D and E with new suffixes. These suffixes enlighten the user about the package type, grade (temperature and plating), and carrier. It also carries undocumented codes, potentially related to factory calibration. Some of the custom codes make the device quite more expensive, see ATSAMC21E17A-MUT ($2.16/5k) vs. ATSAMC21E17A-MUT510 ($2.74/5k). Can calibration justify such a value differential?

NXP is beefing up its MCX A series by adding a new higher end A15x variant.
MCX A are general-purpose Cortex-M33 MCUs designed to address a wide range of applications with scalable device options, low power and intelligent peripherals. The innovative power architecture is designed to support high utilization of I/Os and power efficiency with a simple supply circuit in a smaller footprint. Designed to support more GPIO pins for additional external connections, the MCX A allows designers to utilize a smaller package, simpler board design and lower system BOM costs. See below for details.
New package variants were introduced for the MCX C (Cortex-M0+) and for the MIMXRT101/6.
On another note, NXP announced the i.MX RT700 crossover MCU family with up to five computing cores. This includes a primary Cortex-M33 running at 325 MHz, with integrated HiFi 4 DSP for more demanding DSP and audio processing tasks. It also features NXP’s eIQ Neutron NPU, enabled with the eIQ machine learning software development environment. The family scales up to a best-in-class 7.5MB of ultra-low power SRAM with zero wait-state access. The i.MX RT700 also includes an ultra-low power sense compute subsystem with a second Cortex-M33 and integrated Cadence Tensilica HiFi 1 DSP. This removes the need for an external sensor hub, reducing system design complexity, footprint and BOM costs.
Renesas introduced a couple of dozen variants of existing products.

ST is bringing some performance boost to its cost-efficient STM32C0 series.
WIth up to 128Kbyte of Flash and 24Kbyte of RAM, the STM32C071 MCUs add USB Host and crystal-less Device as well as TouchGFX support. With USB on-chip, designers can easily save at least one external clock and four decoupling capacitors to cut the bill of materials and ease PCB layout. Also, having only one power-supply pair helps to simplify the PCB design, new product designs can become slimmer, trimmer, and more competitive.
The STM32C0 MCUs feature a Cortex-M0+ core and can replace legacy 8-bit or 16-bit MCUs in equipment like home appliances, simple industrial controls, power tools, and IoT devices.
32 new devices were uncovered.
TI released 46 parts, mostly for low cost M0G3x but also for the MSP430F2/4/5/6 and the F28P65 (automotive).
A mixed back to school

Even if the summer months are traditionally quieter, there were a few releases last month with TI adding more low cost Cortex-M0+ MCUs, both for the automotive and non-automotive markets. Nuvoton disclosed Cortex-M7 parts even though the KM1M7 family had been there in a while. Finally, NXP added parts to its multi-Cortex-M33 family, in support of applications using machine learning.
No significant changes this month.
Microchip added less than 20 products this month, mostly variants of existing products in the PIC16F131x family.
No change this month.
Nuvoton added the first links to its not-so-new-anymore Cortex-M7 parts. Recall the KM1M7C series sports a 160MHz Cortex-M7 with a high-resolution PWM, a high-speed, high-precision AD converter, and a feedback control assist function. The family is focused on power control.
NXP is adding a few parts in the new MXC N94x/54x multi-core family.
If you recall, the MCX N94x and N54x are based on dual Cortex-M33 cores running up to 150 MHz, with 2MB of Flash with optional full ECC RAM, a DSP co-processor and an integrated eIQ Neutron NPU. The NPU delivers up to 42x faster machine learning throughput compared to a CPU core alone.
The MCX N94x offers a wider set of analog and motor control peripherals, while the MCX N54x family provides peripherals ranging from high-speed USB with a PHY to secure digital (SD) and smart card interfaces.

No significant changes.
ST added a few parts this month, all variants of existing parts.
TI released 37 parts, mostly for the Automotive market with the TMS320F28Pxx, the TMS280015x, and the M0G31/35.
TI added a handful non-automotive low cost Cortex-M0+ parts, the MSPM0G.
