This slide has several PSoC terms, which should all be familiar from other PSoC presentations. PSoC 4 BLE is an ARM M0 based MCU with programmable analog and digital. PRoC BLE does not have the system hardware programmability of PSoC, but it does have the M0, CapSense, and serial communication blocks. EZ BLE modules are Cypress' Brand New family of modules, and the EZ BLE PRoC module is the first of its family which is based on PRoC BLE IC.
