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
