Reconfigurable architecture challenges stand-alone microcontrollers
A new Programmable System-on-Chip (PSoC) architecture from Cypress Semiconductor combines analog and digital fabric with CapSense capacitive touch technology and the 32-bit ARM Cortex-M0 core. The PSoC 4 is a custom mixed-signal SoC with programmable analog and digital blocks combined with flexible routing and interconnects. Cypress suggests that designers can replace an entire portfolio of proprietary MCU-based solutions and migrate legacy 8- and 16-bit designs to a single 32-bit platform with PSoC 4.
For analog input, the chip features a high-performance successive-approximation analog-to-digital converter with 12-bit resolution sampling at 1 Msps. Low-power modes include a full stop feature that consumes only 20 nA while still retaining its ability to wake up and a retention sleep mode that draws only 150 nA without disturbing SRAM data. PSoC 4 leverages a graphical system design-based integrated development environment, PSoC Creator, enabling designers to drag and drop precharacterized, production-ready analog and digital IP blocks into a single PSoC device to create customized products.
