32-bit Arm® Cortex®-M0 PSoC® 4200 Programmable Digital MCUs

The PSoC® 4200 family boosts the flexibility and performance of the PSoC 4 portfolio by adding programmable, Universal Digital Blocks (UDBs). UDBs can be configured to set-up custom digital interfaces, state machines, and custom logic functions. The PSoC 4200BL includes an integrated Bluetooth Low Energy radio and subsystem.

Universal Digital Blocks

Universal digital blocks are programmable digital blocks that can be configured for custom state machines, custom logic functions, or custom digital interfaces. UDBs can be cascaded together to create wider than 8-bit functions.

UDBs can be configured via a variety of design methods in the PSoC Creator IDE tool suite. These methods include using digital logic components in schematic capture, using the graphical state machine editor, or using Verilog code in the code editor.


Three Design Methods Used to Create Custom Digital Logic Using UDBs in PSoC Creator

1. Use digital logic Components…

2. Or the graphical state machine editor…


Application Example: USB Digital Microphone

PSoC Enables:

  • High-performance USB audio streaming using DMA and precision clocks, allowing up to 24-bit 96-kHz stereo
  • Up to eight I2S audio channels using Universal Digital Blocks (UDBs)
  • 电容式触摸界面
  • Battery management with programmable analog front end
  • LEDs with TCPWM
