This month, SiLabs came up with more solutions for the Amazon Sidewalk (EFR32SG) and Bluetooth (EFR32FG) markets and leveraged its Cortex-M33 architecture to serve the more general purpose arenea with a non-wireless variant (EFM32PG). Microchip added to its portfolio of automotive line while TI continues tirelessly to crawl back into the MCU market with its Cortex-M0+ based MSPM0 line up.
No significant change beyond 3 new parts in the CY9BF family (Coxtex-M3).
Microchip created close to 60 new products in the AVR32EA/64EA and PIC16/18. The EA families with 20 MHz core 64kB/6kB Flash/RAM is recommended for safety-critical applications targeting industrial and automotive products (IEC 61508 and ISO 26262).
On the EFM32 front, SiLabs released 4 new products to create the EFM32PG28 family. It is based on an 80 MHz Cortex M33 with LCD controller. It is a sister MCU to the EFR32xG28 wireless SoC platform (ZG28, FG28 and SG28). The PG28 is also the first EFM32 device with a hardware AI/ML accelerator allowing for faster inferencing at the edge with lower power consumption.
And on the wireless side, it released another 23 products across 2 families, the EFR32SG2x and the EFR32FG28.
The EFR32SG23 is a secure wireless SoC for Amazon Sidewalk devices that supports sub-GHz FSK, providing range beyond the front door to cover detached buildings, pools, and spas. The multi-core device has an ARM Cortex-M33 running up to 78 MHz and with 512 kB of Flash and 64 kB of RAM. It targets battery operated end devices like sensors including door, window, and temperature sensors devices.
The big brother EFR32SG28 bumps up the Flash/RAM sizes to 1MB/256kB.
The EFR32FG28 takes the same digital architecture but supports both sub-GHz and 2.4GHz to add Bluetooth.
Overall, 23 products were released.
ST had only minor changes to its portfolio.
TI continues to expand its portfolio of ultra low cost MSPM0L/G with 8 new devices, all in the 1306 family, with a 32 MHz Cortex-M0+ running at 32 MHz with ADC and 2 operational amplifiers.
Microchip is cleaning up its portfolio of MCU products, the largest in the industry with more than 13,000 part numbers. At the same time, Silicon Labs and TI expand their wireless and low-cost portfolios.
No significant change.
Microchip had a pretty severe cleanup this month, with over a thousand products only accessible through a search or being removed completely. About 80% of parts were in the dsPIC30F dsPIC33FJ families, and the rest with ATTiny 13 and PIC24FJ/HJ.
Renesas beefed up the RL78 F12/F14/F15 and D1A families, for the automotive market and G15 for the GP market. 400+ part numbers were released.
240 products were added.
9 new products were released this month in the EFR32BG27 and EFR32MG27 families.
The EFR32BG27 offers a WLCSP package (2.3 mm x 2.6 mm) capable of running on button cell batteries. It is a Bluetooth 5.x device with an integrated DCDC boost that allows operation down to 0.8 volts, enabling support for single-cell alkaline and 1.5-volt button cell batteries that are typically used in medical applications for battery-operated patches and continuous glucose monitoring (CGM) devices. The wakeup pin allows products in a warehouse or transit to remain off for months, consuming less than 20 nA, ensuring the battery remains fully charged for use. The integrated coulomb counter enables accurate battery level monitoring to avoid unexpected battery depletion for critical applications. Target applications include connected medical devices, wearables, sensors, switches, smart locks, and both commercial and LED lighting.
The EFR32MG27 expands the BG27 into Zigbee and proprietary protocols.
The power figures for both are top of the line with 3.6 mA RX current (1 Mbps GFSK) and 4.1 mA TX current @ 0 dBm output power.
ST had no significant changes.
TI expanded its portfolio of ultra low cost MSPM0L/G with 14 new devices, 2 in the MSPM0L11xx, 10 in the MSPM0L13xx and 2 in the XMSM0G35xx families. As a reminder, these are ultra low cost Cortex-M0+ running at 32 MHz. The porfolio starts at $0.38/1ku with 16kB/2kB of Flash/RAM, 2 UART, 2 I2C, 1 SPI and a temperature range of -40 to 125C. This is a serious competitor to STM32C0 family whose lowest cost MCU is the STM32C011J4M6 at $0.4313/10k. The battle for the lowest-cost Cortex-M is on.
