The lowest frequency Cortex-M
06
Dec
2017
It was great seeing some cleanup at NXP to make room for innovative products like a very low frequency (for a 32-bit architecture) Cortex-M NFC LPC8N04FHI24. SiLabs beefed up their propietary protocol EFR32FG family with a mid-range product, the FG14. Renesas continues to invest into the RXv2 core with 2 new families focused on applications requiring secure elements, the RX65N and RX651.
Looks like we have a new load of 100 parts for SAM4E16, 4S16, 4S2/4/8, 4SA16, 4SD16/32 (Cortex-M based) products. Most of these are MRL B (revision B of the silicon) with new combinations of packages including MN, UU, CN, CF and AN. There was also the creation of the ATSAME51J20 doubling the Flash size to 1MB of its smaller cousin, the ATSAM351J19 as well as the V70N, adding 100-pin packages to the V70.
No change.
No significant change.
66 parts made their debut in the PIC16 and PIC18 families, here is the split:
- 8 were PIC16
- The remaining parts were from the PIC18(L)F25/6 family
No change.
No change.
Only a few parts were added this month at NXP including an interesting Cortex-M part with NFC, the LPC8N04FHI24. With 8MHz it is one of the lowest frequency part of the Cortex-M market. The second lower frequency we have seen is the MKE, also from NXP, running at 20 MHz.
There was also a nice cleanup of older generations of Kinetis MK products, most of them NRND or defintely gone. We captured 84 of them, from MK10 to MK20/30/40/51/53/60 100MHz to MK21 and MK22 120MHz. The MK11/21 50MHz got a new silicon revision.
Renesas uncovered 130 new products in the RX family, the R5F5651C/E, R5F565NC/E.
The RX65N and RX651 Groups are new mainstream RX microcontrollers with a 120MHz-RXv2 core, large-capacity RAM, and enhanced security, connectivity, and HMI.
The RX65N/RX651 can be divided into 1MB or less and 1.5MB or more flash. The former has 256kB RAM with Ethernet, USB, CAN, SD host/slave interface, and quad SPI while the latter has even more enhanced encryption functionality with 640kB RAM, LCD controller and 2D graphics engine.
SiLabs
No significant change.
The STM8 got 10 new parts in the STM8AF63, AL31, S105 and S207 families.
No significant change.
PSoC6 expands to the low end

More products are coming under the PSoC6 banner this month. Cypress is expanding toward the low end with 50MHz devices as well as non Bluetooth versions. This contrasts with the calm of TI, SiLabs, NXP (soon-to-be Qualcomm) or worse, Microchip who is retiring close to 50 parts this month from its original portfolio. ST and Microchip/Atmel are pushing higher temperatures with respectively 125C and 105C.
We noticed a few additions (6 products with CN and CNR suffix) in the Cortex-M4-based SAM4E family with higher temperatures for the BGA packages (105C) while the 8-bit ATtiny41 expanded toward the low end with 6 ATtiny414/6 featuring 20 MHz, 4kB of Flash and 256 bytes of RAM.
No change.
No change.
This month, Microchip performed some cleanup by removing close to 50 parts, none were added and here is the split:
- About half were DSPIC33EP64/128/256/512
- A quarter were PIC16(L)F1xxx
- The remaining parts were from the PIC24EP128/256/512 family
No change.

No change.
No significant changes this month at Renesas RX and RL78.
No change.
Cypress is building its PSoC6 family and we are updating our last post with new devices released this month, 25 devices overall.
The PSoC 6 MCU architecture is built on a low power 40nm process, embeds a Cortex-M4 and an optional Cortex-M0+ core. Active power consumption can be as low as 22-µA/MHz (M4) and 15-µA/MHz (M0+).
The PSoC6 is comprised of 4 lines:
- PSoC60 – value line: only a 50MHz Cortex-M4 and basic CapSense with a max of 128/512kB of RAM/Flash.2 parts this month, the CYC8C6016/36BZI-F04
- PSoC61 – programmable(?) line: boosts frequency to 150MHz and memory to 288/1024 kB of RAM/Flash with additional CapSense features, crypto acceleration and USB.
7 parts were added. - PSoC62 – performance line: adds a 100MHz Cortex-M0+ and a full trusted execution environment.
5 parts were added. - PSoC63 – connectivity line: add BLE including its PHY and doubles the memory footprint. 12 parts are available. If we dig deeper, it is interesting to see that the PSoC63 distinctive feature is BLE. If it can run a full BLE stack on a Cortex-M4 at 50MHz, how will the integration with the application code happen is an open question. The PSoC63 borrows lower features from the other lines, in particular:
- PSoC631: only a Cortex-M4 running at 50MHz, optional crypto, no Capsense
- PSoC633: Cortex-M4 running at 150MHz, no crypto, optional Cortex-M0+ and Capsense
- PSoC634: full house
11 parts were added.
Nothing stood out this month at ST. In all, 16 part numbers came up, most with T&R packing. A few were still worth it:
- The STM32F401/412 and STM32L433 got +125C temperature grade.
- The STM32H74/53AII6 are in proposal mode. These are UFBGA variants with -40C +85C temperature grade.
The XCC2640R2FTWRGZTQ1 was removed.
