Cypress Semiconductor unveiled PSoC 6, its newest microcontroller (MCU) architecture that is purpose-built for the Internet of Things (IoT). The architecture is built on ultra-low-power 40 nm process technology and delivers one of the industry’s lowest-power and most flexible solutions, with integrated security features required for next-generation IoT devices.
The architecture fills a gap in the IoT solution space between power-hungry and higher-cost application processors and performance-challenged, single-core MCUs. The dual-core ARM Cortex-M4 and Cortex-M0+ architecture lets designers optimise for power and performance simultaneously.
Cypress’ proprietary 40 nm SONOS process technology enables the PSoC 6 MCU architecture to feature power consumption of 22 μA/MHz and 15 μA/MHz of active power on the ARM Cortex-M4 and Cortex-M0+ cores, respectively. With dynamic voltage and frequency scaling (DVFS), PSoC 6 offers both performance- and power-critical processing capability. The dual-core architecture enables power-optimised system design where the auxiliary core can be used as an offload engine for power efficiency, allowing the main core to sleep.
