General description
PSoC™ 6 MCU is a high-performance, ultra-low-power and secured MCU platform, purpose-built for IoT
applications. The CY8C61x6/7 product line, based on the PSoC™ 6 MCU platform, is a combination of a
high-performance microcontroller with low-power flash technology, digital programmable logic,
high-performance analog-to-digital conversion and standard communication and timing peripherals.

Features
• 32-bit dual CPU subsystem
Note: In PSoC™ 61 the Cortex® M0+ is reserved for system functions, and is not available for applications.
