RIP STM8

2023

ST continues its fireworks in 2023 with the retirement of virtually all the STM8 portfolio. It is holding its promise:
“your next 8-bit MCU is a 32-bit MCU, the STM32C0”. The cleanup did not stop there with the NRND of the STM32L1xx families. SiLabs did not sit still either on the wireless side with the announcement of the heavy duty EFR32FG25, a sub-GHz swiss army knife for smart metering, lighting, city and building automation.


Infineon
There were new CY8C4149 parts in the Cortex-M0+ based PSoC 4100S Max family.
Microchip
This month, Microchip added 35 parts of which 20 where of the PIC32CX family. Microchip is growing its small existing set of Cortex-M based parts. It is a 120 MHz Cortex-M4 mid range family with ethernet and CAN-FD.
Nordic
No change.
Nuvoton
Nuvoton launched the M0A2x series. Both M0A21/23 use a 48 MHz Cortex-M0 core with -40/+125C temperature range, 2.4V ~ 5.5V operating voltage and LIN interface for robust communication. They target robust and high operating temperature applications, such as 24 GHz mmWave radar, car lighting, electric window lifter, and power seat and intelligent power supply.
The MA023 adds a CAN 2.0B interface and supports a larger Flash size.
NXP
No change.
Renesas
The RA family had a handfull of new suffix. In the RL78 family, we saw for the first time the RL78/G22, focused on low power (37.5µA/MHz) and touch. It uses a 32 MHz RL78 core, with a variety of 16-48-pin packages and 32-64 KB of flash memory. The RX had 200 variants of existing parts.

SiliconLabs
SiLabs launched the EFR32FG25 wireless SoCs, with long range, Sub-GHz wireless connectivity for smart metering, lighting, city and building automation. The inclusion of multi-rate OFDM, FSK, and OPSK modulation schemes allows for data rates up to 3.6 Mbps while keeping immunity to 2.4 GHz interference. The large memory footprint and increased IO count allows for design consolidation and when combined with Secure Vault can provide higher level system security. 10 products were unveiled with a 97.5 MHz Cortex-M33 and up to 1920kB of Flash and 512 kB of RAM.
ST Microelectronics
ST continues its massive portfolio overhaul with the retirement (NRND) of virtually all of its STM8 portfolio. This is the result of the STM32C0 announcement last month, their lowest cost 32 MCU that cannibalized the STM8. This is a bold move that allows customers to upgrade easily to a slew of options in the STM32 portfolio.
ST did not stop there and is now cleaning up its STM32 portfolio with the retirement of another family, the Cortex-M3 STM32L1xx. There was too much overlap with the STM32L0 (Cortex-M0+) with little benefit of the Cortex-M3.
Texas Instruments
No significant change to the TI portfolio this month.
