What is PSoC? PSoC = Programmable System-on-Chip A family of mixed-signal arrays made by Cypress Semiconductor Corporation A microcontroller and configurable integrated analog, digital, and communications peripherals. PSoC provides programmable mixed-signal controller functionality for embedded control applications UCSD COSMOS PROGRAMDR. CHOON KIM3 C or Assembly language Analog and Digital M8C Microcontroller unit amplifiers, ADCs, DACs, filters, comparators timers, counters, PWMs I2C, SPI, UART, USB, etc
