AN91267 Datasheet, PDF (2/62 Pages) Ramtron International Corporation – Getting Started with PSoC

Introduction
BLE is an ultra-low-power wireless standard defined by
the Bluetooth Special Interest Group (SIG) for short-range
communication. It features a physical layer, protocol stack,
and application use cases, all designed and optimized for
the lowest power consumption.
The Cypress PSoC 4 BLE device is a programmable
embedded system-on-chip that integrates a BLE radio,
programmable analog and digital peripherals, memory,
and an ARM Cortex-M0 microcontroller on a single chip.
PSoC 4 BLE provides a cost-effective alternative to the
combination of an MCU and an external BLE radio. In
addition to reducing the overall system cost and size, the
programmable analog and digital subsystems allow
flexibility and fine-tuning of the design using
PSoC Creator, the schematic-based design tool for
designing applications for PSoC 4 BLE.
PSoC 4 BLE simplifies the RF board design with its
integrated balun circuit, which reduces the number of
external components required for antenna matching. The
BLE protocol stack library is integrated with PSoC Creator
and is free of cost. It can be easily configured using a
simple graphical user interface (GUI), allowing you to
jump-start your BLE design in minutes.
PSoC 4 BLE offers a current consumption of 150 nA while
retaining the SRAM contents, programmable logic, and the
ability to wake up from an interrupt. It consumes only 1.3
µA in Deep-Sleep mode while maintaining the BLE link
active. A combination of these low-power modes and
flexible analog and digital peripherals provides a single
chip solution with best-in-class system power consumption
for battery-operated BLE designs such as wearable fitness
monitors and wireless sensor interfaces.
Cypress’s capacitive touch-sensing feature in PSoC 4
BLE, known as CapSense^®, offers unprecedented signal-
to-noise ratio, best-in-class waterproofing, and a wide
variety of sensor types such as buttons, sliders, track
pads, and proximity sensors that are gaining popularity in
wearable electronic devices such as activity monitors and
health and fitness equipment.
In addition to PSoC 4 BLE, Cypress offers PRoC™ BLE, a
fixed-function BLE device that focuses on human interface
device designs such as keyboards, mice, and remote
controls. See the Getting Started with PRoC BLE
application note for details. See Appendix A: BLE Device
Family Comparison for a comparison of the BLE device
families from Cypress.
The Cypress PSoC portfolio also contains PSoC 1,
PSoC 3, PSoC 4, and PSoC 5LP, which do not support
BLE. These devices offer different system architectures
and analog and digital peripherals. For more information,
refer to the Cypress Platform PSoC Solutions Roadmap.
