Cypress Semiconductor CY8C3866AXI-040, CMOS System On Chip SOC 100-Pin TQFP

The PSoC 3 (Programmable Embedded System-on-Chip) family consists of 8051-core microcontroller devices featuring configurable blocks of analogue and digital logic, and programmable interconnects. Additionally, Flash program memory, SRAM data memory and configurable I/O are included.

PSoC® 3 is a true programmable embedded system-on-chip, integrating configurable analog and digital peripherals, memory, and a microcontroller on a single chip. The PSoC 3 architecture boosts performance. PSoC devices employ a highly configurable system-on-chip architecture for embedded control design. They integrate configurable analog and digital circuits, controlled by an on-chip microcontroller. A single PSoC device can integrate as many as 100 digital and analog peripheral functions, reducing design time, board space, power consumption, and system cost while improving system quality.
