Cypress Semiconductor CY8C4248LQI-BL553, 32bit ARM Cortex M0 CPU Microcontroller, CY8C4248LQI, 48MHz, 256 kB Flash,

PSoC 4 is a scalable and reconfigurable platform architecture for a family of programmable embedded system controllers with an Arm® Cortex®-M0 CPU. It combines programmable and reconfigurable analogue and digital blocks with flexible automatic routing. The PSoC 4200_BL product family, based on this platform, is a combination of a microcontroller with an integrated Bluetooth Low Energy (BLE), also known as Bluetooth Smart, radio and subsystem (BLESS). The other features include digital programmable logic, high-performance analogue-to-digital conversion (ADC), opamps with Comparator mode, and standard communication and timing peripherals. The programmable analogue and digital subsystems allow flexibility and in-field tuning of the design.
