STMicroelectronics offers STM32 in eight-pin package

STM32 microcontrollers are now available in an eight-pin package. According to STMicroelectronics, this enables simple embedded projects to leverage 32-bit performance in a compact and cost-effective outline.

The company has released four STM32G0 devices which combine eight-pin economy with a 64MHz Arm Cortex-M0+ CPU giving 59 DMIPS, up to 8kbyte RAM and 32kbyte flash on-chip. Peripherals include a 2.5Msample per second analogue to digital converter (ADC), high-resolution timer, and a high-speed serial peripheral interface (SPI). Designers can map I/O pins and internal MCU functions to upgrade end-product functionality without sacrificing board real-estate or increasing bill of materials costs. The internal oscillator is accurate to ± one per cent over wide temperature and voltage ranges, which also saves external clock components, says ST.

The low power design eight-pin STM32G0 devices can be used in energy-conscious applications governed by battery-capacity limits, eco-design legislation, or market expectations such as appliance energy ratings.

The microcontrollers are designed for scalability with up to 100 package pins, up to 512kbytes flash, additional high-performance analogue peripherals, and cyber-protection features.

The eight-pin STM32G0 microcontrollers are available now in 6.0 x 4.9mm SO8N. The eight-pin Discovery kit, STM32G0316-DISCO, is also available.

The STM32G031J6, STM32G031J4, and STM32G041J6 access line microcontrollers are also available in SO8N, offering additional functionality including a hardware AES acceleration, securable memory area enabling secure boot or firmware update, extra timers, and 96-bit unique device ID.
