5.2.2 Smart Snippets
The PAN1740 is available together with Dialog’s SmartSnippets
TM
Bluetooth Software
platform which includes a qualified Bluetooth Smart single-mode stack on chip.
Numerous Bluetooth Smart profiles for consumer wellness, sport, fitness, security and
proximity applications are supplied as standard, while additional customer profiles can be
developed and added as needed.
The SmartSnippetsTM software development environment is based on Keil
TM
‘s uVision
mature tools and contains example application code for both embedded and hosted modes.
5.2.3 Memory
The following memories are part of the PAN1740’s internal blocks:
ROM. This is a 84 kB ROM containing the Bluetooth Smart protocol stack as well as the
boot code sequence.
OTP. This is a 32 kB One-Time Programmable memory array, used to store the application
code as well as Bluetooth Smart profiles. It also contains the system configuration and
calibration data.
System SRAM. This is a 42 kB system SRAM (Sys-RAM) which is primarily used for
mirroring the program code from the OTP when the system wakes/powers up. It also serves
as Data RAM for intermediate variables and various data that the protocol requires.
Optionally, it can be used as extra memory space for the BLE TX and RX data structures.
Retention RAMs. These are 4 special low leakage SRAM cells (2 kB + 2 kB + 3 kB + 1 kB)
used to store various data of the Bluetooth Smart protocol as well as the system’s global
variables and processor stack when the system goes into Deep Sleep mode. Storage of this
data ensures secure and quick configuration of the BLE Core after the system wakes up.
Every cell can be powered on or off according to the application needs for retention area
when in Deep Sleep mode.
