Renesas closes dialog acquisition

There was a good series of annoucement this month where security had a prominent place at the table, in particular the Cortex-M33 and all of its security bells and whistles. SLAB came back from the dead after announcing a new (although based on an existing family) EFM32PG22. Renesas continues to bet big on the Cortex-M core in expanding the RA family further. Finally Nuvoton had its own release of a secure Cortex-based family too, the M23 one.
Oh, and you remember that offer Renesas made to purchase Dialog Semiconductor on the 7th this month? Well it went through, and Renesas has agreed to acquire Apple Inc. supplier, for $5.9B.
Dialog got acquired by Renesas last month, no change to the portfolio.
No change yet, before the merge storm with Cypress.
There were close to 40 new products this month, with over half being automotive-grade variant in the ATSAM, DSPIC33, AVR64 and PIC18F2xQ families. DSPIC33EPxxxxGM, PIC16LF1713 were among the 65 that dropped out.
No change.
Nuvoton launched the NuMicro® M2354 Series, building on the security features of NuMicro® M2351 Series that have been Arm® PSA Certified™ Level 1, Level 2 and PSA Functional API Certified The M2354 Series microcontrollers are based on Arm® Cortex®-M23 with TrustZone® and also adds protection functions against side-channel attacks to cryptographic hardware accelerators as well as fault injection attacks of voltage and clock pin surges.
The M2354 runs at a frequency of up to 96 MHz, with 1MB/256kB of Flash/RAM memory.
In Normal Run mode, it consumes 89.3 μA/ MHz with LDO power supply and 39.6 μA/ MHz with DC-DC power supply. The Standby Power-Down mode consumes less than 2 μA. In Deep Power-Down mode with VBAT power supply, it consumes 0.5 μA for 80-bytes content retention of RTC registers. It can further down to 0.1 μA if there is no need to keep the 80-bytes content of RTC registers.
Three products are available today with packages from 48 to 128 pin and temperature range of -40 to +105C.
NXP announced the i.MX 8M Plus family with a focus on machine learning and vision, advanced multimedia, and industrial automation with high reliability. It is built to meet the needs of Smart Home, Building, City and Industry 4.0 applications. Not quite a microcontroller, it embeds 2 or 4 Cortex-A53 processors with a Neural Processing Unit.
Renesas continues to expand the RA Family with the RA6M5 (40nm 200MHz Cortex-M33 with TrustZone®).
The integrated Ethernet MAC with individual DMA ensures high data throughput. The RA6M5 is supported by an open and flexible ecosystem concept—the Flexible Software Package (FSP), built on FreeRTOS—and is expandable to use other RTOSes and middleware. The RA6M5 targets Ethernet IoT applications,with low active power consumption down to 107uA/MHz. Features include:
- 1MB – 2MB Flash memory and 448kB SRAM with Parity and 64kB SRAM with ECC
- Scalable from 100-pin to 176-pin packages
- Ethernet controller with DMA
- Capacitive touch sensing unit
- USB 2.0 High-Speed and Full Speed
- CAN FD (CAN 2.0B option)
- QuadSPI and OctaSPI
- SCI (UART, Simple SPI, Simple I2C)
- SPI/ I2C multimaster interface
- SDHI and MMC
Renesas also added to the RL78 family with the low power RL78/G23 group. With 44μA/MHz CPU operation, it has a very low power consumption with 210nA at stop (4KB SRAM retention). Operating voltage ranges from 1.6V to 5.5V at up to 32MHz, a range of package pin counts from 30 to 128, and up to 768KB of flash memory. In addition to enhanced analog and security features, it incorporates logic and event link controllers (ELCL) and the first capacitive touch sensing unit (CTSU2L) in the RL78 family. LQFP, QFN, LGA, BGA, WLCSP packages are available for the first 32 part numbers.
In the RX family, 26 variants of existing parts were released.
YES! After almost a year of drought, SiLabs has released the EFM32PG22, a pin and software compatible MCU-only version of the EFR32xG22 wireless SoC platform (BG22, MG22 and FG22). It offers a 76.8MHz Cortex-M33 with analog and communication peripherals. Features include:
- ARM Cortex-M33 @76.8 MHz
- Up to 512 kB of flash
- 32 kB RAM
- 27 μA/MHz Active, 1.1 μA EM2 with 8 kB RAM, 0.5 uA w/ RTC in EM4
- 2x USART, 2x I²C, 1x EUART and PDM
- 16-bit ADC (16 channels)
- Built-in 32 kHz, 500 ppm sleep XTAL
- ±2 °C temperature sensor
- -40 °C to +125 °C
- 1.71 V to 3.8 V single power supply
- Packages:32-pin QFN (4 mm x 4 mm) (18 GPIO) or 40-pin QFN (5 mm x 5 mm) (26 GPIO)
Cypress/Infineon released 7 variants of existing parts, in the PSoC4200 and PSoC 4S series.
ST deployed 26 STM32 variants of existing parts, nothing overly noticeable…
TI only had a few minor variants this month in the MSP430 family mostly.
