PSoC® 4000

PSoC® 4000

PSoC 4000 is a low-cost, entry-level 32-bit ARM-based SoC for quick, simple upgrades of legacy 8-bit and 16-bit MCUs. The PSoC 4000 family delivers PSoC’s hallmark design flexibility along with CapSense, Cypress’s industry-leading capacitive sensing technology, to cost-sensitive and high-volume applications. The PSoC 4000 family also integrates programmable digital and analog peripherals, such as timers/counters/PWMs, I²C and comparators, to suit a variety of consumer and industrial applications. These devices are available in footprint packages as small as 3 x 3 x 0.6 mm.

Upgrade Legacy 8-bit and 16-bit MCUs
  • Embedded system designs now require higher-performing MCUs at the same cost
  • SoC 4000 offers a 32-bit ARM Cortex-M0 MCU to meet processing and power requirements
  • PSoC’s programmable I/O subsystem enables you to easily connect the internal analog and digital signals to the external I/Os to design your custom footprint
Industry’s Best CapSense
  • Enables a touch user interface with up to 16 I/Os
  • Uses SmartSense™ Auto-tuning during all product design phases
  • Prevents false touches caused by liquids
  • Implements advanced proximity sensing: wake-on-approach, liquid level detection, and IR sensor replacement
  • Performs reliably in noisy environments
Scalable Architecture
  • Enables seamless migration up and across all the PSoC 4 device families
  • Accelerates time-to-market with hardware and firmware co-design using the free PSoC Creator Integrated Design Environment (IDE)
  • ARM-friendly ecosystem with support for third-party tools, including code editors, debuggers and programmers, simplifies design with PSoC 4
