Cypress Semiconductor CY8C4146AZI-S455, 32bit ARM Cortex M0 Microcontroller, CY8C4100, 48MHz, 64 kB Flash, 64-Pin TQFP

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 analog 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).

Four opamps with reconfigurable high-drive external and high-bandwidth internal drive, Comparator modes, and ADC input buffering capability Can operate in Deep Sleep mode.
Four programmable logic blocks called universal digital blocks, (UDBs), each with eight macrocells and data path
Cypress-provided peripheral component library, user-defined state machines, and Verilog input
Power Management:
Active mode: 1.7 mA at 3-MHz flash program execution
Deep Sleep mode: 1.5 μA with watch crystal oscillator
