Getting Started with PSoC® 4 BLE
Device Security
PSoC 4 BLE provides a number of options to protect the flash memory from unauthorized access or copying. Each row of
flash has a single protection bit; these bits are stored in a supervisory flash row.
Programmable GPIOs
The I/O system provides an interface between the CPU and the peripherals and the outside world. PSoC 4 BLE has up to 36
programmable GPIO pins. You can configure the GPIOs for CapSense, LCD, analog, or digital signals. PSoC 4 BLE GPIOs
support multiple drive modes, drive strengths, and slew rates.
PSoC 4 BLE offers an intelligent routing system that gives multiple choices for connecting an internal signal to a GPIO. This
flexible routing simplifies circuit design and board layout.
