Keremi tracking more MCUs, MCHP invests in automotive




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.
ST Microelectronics
STM32 had only minor changes. The STM32WB55 now shows 5 devices with -40/+85 and -40/+105 temperature grades.
Texas Instruments
TI had minor changes.
