It’s been a relatively quiet month with main events centering on new parts at Renesas RX64M and improved RF performance and crypto for Nordic’s nRF52840 multi protocol MCU.
ATTINY8 and 16 got a few parts while the ATSAME/S70 added revision B of the silicon and one more V70 part got the VAO treatment (automotive grade).
The DSPIC33EP128GS702 was removed and a few more VAO parts came out for the other DSPIC33EP128 as well as for the PIC12 and PIC16, 9 parts overall. 14 new PIC18F24Q/25Q appeared adding to the 350 existing ones of the same family.
Nordic released a new revision of its nRF52840 using ARM CryptoCell 310 (and its middleware) and an improved performance in TX and RX consumption.
It looks like the MKS22 is now being removed from the US site, it does appear in the general search but not in the product selector.
Renesas added close to 50 part numbers to its high performance RX64M group running at 120 MHz with Flash memory ranging from 2 to 4MB.
There was a change in nomenclature on the EFM8UB family. The parts now have the package type and pin count as a suffix. The SIM3L157/167 have been retired from the product list as they have been EOL for a while.
Cypress launched the PSoC4 4100PS with 12 products. The 4100PS is based on a Cortex-M0+ with 32/4kB Flash/SRAM and includes capacitive sensing, segment LCD support and operates from a 1.71-5.5V supply.
On the PSoC6, we have lost the PSoC 61, CY8C61xxBZI-Fx4, 7 parts in all.
STM32 had only minor changes.
TI launched the MSP430FR21/23 family with 23 PNs in the value line to target the industrial market with extended temperature range (-40 to 105C). The family has a MSP430 core running at up to 24MHz with up to 32kB of FRAM.
We are initiating coverage of the NXP QN90xx Bluetooth family as well as the NXP i.MX RT, a high performance Cortex-M7, and the Cortex-M-based Renesas Synergy MCUs with a few others in the pipeline. Microchip seems to be investing in automotive, with no less than 900+ new automotive qualified parts released. Enjoy!
AT32UC3 lost another 40 parts, and fewer than 90 remain while ATMEGA gained 25. On the Cortex-M front, the ATSAMS70 got a revision B of the silicon and is being swapped with the A revision.
There was a significant push in the automotive space with 921 new parts that are declared automotive grade with a VAO suffix, with heavy representation of DSPIC33 and PIC16. If you are interested, here is a detailed presentation on the topic.
NXP released the LPC51U, a LPC541xx pin-compatible family now in pre-production. 2 parts are offered, with a 100MHz Cortex-M0+, 256kB/96kB of Flash/SRAM, a Full-Speed USB, in LQFP48 and 64 pins packages.
We are starting to track this month the QN90xx families, supporting the Bluetooth low power segment. They are split between the QN908x serving BT5.0 with a Cortex-M4 while the QN902x focuses on BT4.2 with a Cortex-M0. It is unclear from the documentation whether this is a single core solution with the Cortex-M dealing with both the application code and the modem code, or whether there is a hidden additional processor running the modem function. Interestingly, on the QN908x, there is a fusion sensor processor, essentialy a hardware block that can perform low level DSP function like 9×9 matrix multiplication, 64 to 256-point FFT-type operations.
We are also initiating coverage on the i.MX RT family, a high performance Cortex-M7 based family bridging the gap between MCUs and application processors. The family comes in 3 flavors from 256kB to 1MB of RAM, but no embedded Flash. The family rely on a quad-SPI and a parallel interface to external NAND or NOR Flash memories. Additional features include a 2D graphics acceleration engine, a parallel camera sensor interface, a LCD display controller (up to WXGA 1366×768) and 3x I2S interfaces for audio streams. Devices run at 528 or 600MHz with a starting price below $3/10k.
We are initiating coverage of the Synergy platform, a full solution offer of Renesas America. The platform includes silicon but also Synergy software packages well beyond a basic BSP, tools kits and a list of partners. We focus on the silicon part that Renesas has split in 4 series, interestingly, all of them include at a minumum a USB controller and AES128/256:
– S1 ultra-low power, Cortex-M0+, 32MHz, 64-256 kB FLash
– S3 high efficiency, Cortex-M4, 48MHz, 130nm process, 256-1024 kB Flash, segment LCD and touch
– S5 high integration, Cortex-M4, 120MHz, 512-2048 kB Flash, graphic LCD, Ethernet
– S7 high performance, COrtex-M4, 240MHz, 3072-4096 kB Flash
SiLabs expanded the Giant Gecko GG11, Series 1 family with now 60 EFM32GG11 parts. The GG11 Series 1 uses a Cortex-M4 core running at 72 MHz (80µA/MHz in active mode) with combinations of 1 or 2 MB of Flash with 512 or 384 kB of RAM a solid crypto engine with AES128/256, SHA1/2 and ECC, Ethernet and USB support on selected parts. It was announced in July last year with pricing starting at $5.66/10k.
On the wireless side, the EZR32HG220F lost 5 parts while the EFR32BG13P gained 4 and the EFR32MG13P gained 3.
Cypress is migrating its MB9BF (FM4 parts) to a new nomenclature, replacing MB with CY to have CY9BF parts.
STM32 had only minor changes. The STM32WB55 now shows 5 devices with -40/+85 and -40/+105 temperature grades.
TI had minor changes.
