PSoC 4200L, 4200M, 4200BL and 4200 parts boost the flexibility and performance of the PSoC 4 portfolio, by adding Cypress’s unique Programmable Digital Blocks. Programmable Digital Block are hardware blocks like Universal Digital Blocks, Serial Communication Blocks (SCBs) and TCPWMs that can be configured using PSoC Creator to implement custom digital peripherals and glue logic.
UDBs are general-purpose digital logic subsystems which can be configured as timing-critical coprocessors, custom serial communication interfaces for emerging standards or to replace external glue logic ICs. UDBs contain two programmable logic devices (PLDs), one programmable data path with an arithmetic logic unit (ALU), one status register, one control register, and can be configured in PSoC Creator, with the graphical state machine editor or using Verilog code.
