PSoC® 6 MCU is a high-performance, ultra-low-power and secure MCU platform, purpose-built for IoT applications. Based on the PSoC 6 MCU platform, this product line is a combination of a dual CPU microcontroller with low-power flash technology, digital programmable logic, high-performance analog-to-digital conversion and standard communication and timing peripherals.

Features :

32-bit Dual CPU Subsystem

  • 150-MHz Arm® Cortex®-M4F (CM4) CPU with single-cycle multiply, floating point, and memory protection unit (MPU)
  • 100-MHz Cortex-M0+ (CM0+) CPU with single-cycle multiply and MPU
  • User-selectable core logic operation at either 1.1 V or 0.9 V
  • Active CPU current slope with 1.1-V core operation
    • Cortex-M4: 40 µA/MHz
    • Cortex-M0+: 20 µA/MHz
  • Active CPU current slope with 0.9-V core operation
    • Cortex-M4: 22 µA/MHz
    • Cortex-M0+: 15 µA/MHz
  • Three DMA controllers

Memory Subsystem

  • 512-KB application flash, 32-KB auxiliary flash (AUXflash), and 32-KB supervisory flash (SFlash); read-while-write (RWW) support. Two 8-KB flash caches, one for each CPU.
  • 256-KB SRAM with programmable power control and retention granularity
  • One-time-programmable (OTP) 1-Kb eFuse array

Low-Power 1.7-V to 3.6-V Operation

  • Six power modes for fine-grained power management
  • Deep Sleep mode current of 7 µA with 64-KB SRAM retention
  • On-chip DC-DC buck converter, <1 µA quiescent current
  • Backup domain with 64 bytes of memory and real-time clock

Segment LCD Drive

  • Supports up to 63 segments and up to 8 commons.
  • Operates in system Deep Sleep mode

Serial Communication

  • Seven run-time configurable serial communication blocks (SCBs)
    • Six SCBs: configurable as SPI, I2C, or UART
    • One Deep Sleep SCB: configurable as SPI or I2C
  • USB Full-Speed device interface
  • One SD Host Controller/eMMC/SD controller
  • One CAN FD block

Timing and Pulse-Width Modulation

  • Twelve timer/counter/pulse-width modulators (TCPWMs)
  • Center-aligned, edge, and pseudo-random modes
  • Comparator-based triggering of Kill signals

Programmable Analog

  • 12-bit 2-Msps SAR ADC with differential and single-ended modes and 16-channel sequencer with result averaging
  • Two low-power comparators available in system Deep Sleep and Hibernate modes
  • Built-in temperature sensor connected to ADC

Up to 64 Programmable GPIOs

  • Two Smart I/O™ ports (8 I/Os) enable Boolean operations on GPIO pins; available during system Deep Sleep
  • Programmable drive modes, strengths, and slew rates
  • Two overvoltage-tolerant (OVT) pins
