In summary, Cypress's Bluetooth Low Energy (BLE) or Bluetooth Smart portfolio consists of WICED™ SMART, PRoC™ BLE, and PSoC® 4 BLE System-on-Chip (SoC) solutions and System-in-Package (SiP) modules. These are single-mode i.e. Bluetooth Low Energy-only solutions. For dual-mode Bluetooth solutions that support Bluetooth Classic (i.e. Basic Rate and Enhanced Data Rate) as well as Bluetooth Low Energy (BLE), check out the Bluetooth (BR + EDR + BLE) Connectivity Solutions webpage. PRoC BLE (Programmable-Radio-on-Chip with BLE) and PSoC 4 BLE (Programmable System-On-Chip with BLE) are ARM® Cortex®-M0-based SoC families that offer more integration compared to the WICED SMART SoCs. PRoC BLE includes on-chip Flash (up to 256 KB) and an optional CapSense® controller for touch sensing with up to 2-finger gestures. PSoC 4 BLE adds mixed-signal integration with opamps, low-power comparators, and Cypress's unique Universal Digital Blocks (UDBs). These families are supported on Cypress's PSoC Creator™ IDE. EZ-BLE Modules are fully integrated, fully certified, programmable modules designed for ease-of-use and reducing time-to-market. Each Bluetooth Smart module contains Cypress’s PRoC or PSoC 4 BLE chip, two crystals, chip or trace antenna, shield, and passive components.
