Renesas RL78/G15 8-bit MCU is offered in a 3x3mm package
Renesas Electronics RL78/G15 is an entry-level 8-bit microcontroller with 1 KB of SRAM, 4 or 8KB of code flash memory, and offered in package sizes ranging from 8 to 20 pins, down to an 8-pin device measuring just 3×3 mm. STMicro has just unveiled the STM32C0 32-bit microcontroller claiming “your next 8-bit MCU is a 32-bit” with packages from 8- to 48-pins and packages as small as 1.70 x 1.42 mm and 3x3mm, and a price similar to other 8-bit industrial microcontrollers. To that, I say “not so fast STMicro!”, as Renesas has just launched the 16 MHz RL78/G15 8-bit microcontroller family with many of the same features and target use cases as the STMC32C011 sub-family. Renesas RL78/G15 key features and specifications: CPU core – Renesas RL78 8-bit core @ up to 16 MHz Memory – 1NS SRAM, Storage – 4 to 8KB program flash, 1KB data flash Peripheral I/F […]
MistySoM Renesas RZ/G2L or RZ/V2L SoM and devkit goes for $112 and up
We’ve previously written about several system-on-modules and SBCs based on Renesas RZ/G2L or RZ/V2L Cortex-A55/M33 processors such as Geniatech “AHAURA” RS-G2L100 and “AKITIO” RS-V2L100 single board computers, Forlinx FET-G2LD-C system-on-module, and SolidRun RZ/G2LC SOM and devkit. But most of those are hard to buy, and you need to contact the company, discuss your project, etc… before purchase, except for the SolidRun Renesas RZ/G2LC Evaluation Kit going for $249. Another option is the MistyWest MistySOM module offered for $112 and up on GroupGets with either Renesas RZ/G2L or RZ/V2L processor, as well as an optional carrier board.

Sub-$5 Cavli C16QS CAT1.bis cellular IoT module features Qualcomm QCX216 modem
Qualcomm QCX216 LTE IoT modem was announced at the end of last year as one of the first solutions supporting the new CAT1.bis standard enabling smaller, simpler, and cheaper modules with a single antenna design. This chip also integrates a WiFi scanner exclusively used for indoor positioning. Cavli Wireless C16QS CAT1.bis is one of the first cellular IoT modules based on the Qualcomm QCX216, and we now have a clearer idea of what “cheaper” means since the company says it will sell those for less than $5 to OEMs, although that price is likely in very high quantities, possibly 100k+ or one million pieces. Cavli C16QS specifications: Wireless IC – Qualcomm QCX216 with dual-core Cortex-M3 @ 204 MHz, cellular modem-RF Storage – 4 MB Cellular connectivity LTE CAT 1.bis based on 3GPP Release 14 Peak speeds – 10Mbps (DL), 5Mbps (UL) Bands EMEA: B1/B3/B5/B8/B20 North America : B2/B4/B12/B13/B66/B71 Integrated eSIM […]
