PAN1740 Bluetooth Module 2 Overview System Overview The PAN1740 contains the following internal blocks: ARM Cortex-M0 CPU The Cortex-M0 processor is a 32-bit Reduced Instruction Set Computing (RISC) processor with a “von-Neumann-architecture” (single bus interface). It uses an instruction set called Thumb, which was first supported in the ARM7TDMI processor. Several newer instructions from the ARMv6 architecture and a few instructions from the Thumb-2 technology are also included. Thumb-2 technology extended the previous Thumb instruction set to allow all operations to be carried out in one...

PAN1740 Bluetooth Module 2 Overview Memory The following memories are part of the PAN1740’s internal blocks: ROM This is an 84 kB ROM containing the Bluetooth Smart protocol stack as well as the boot code sequence. OTP (One Time Programmable) 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...

Parasonic PAN1740 Bluetooth Module Power Modes There are four different power modes in the PAN1740: • Active Mode System is active and operates at full speed. • Sleep Mode No power gating has been programmed, the ARM CPU is idle, waiting for an interrupt. PD_SYS is on. PD_PER and PED_RAD depending on the programmed enabled value. • Extended Sleep Mode All power domains are off except for the PD_AON, the programmed PD_RRx and the PD_SR. Since the SysRAM retains its data, no OTP mirroring is required upon waking up the system. • Deep Sleep Mode All power domains are off except for the PD_AON...

Parasonic PAN1740 Bluetooth Module 2.5 Interfaces 2.5.1 UART The UART is compliant to the industry standard “16550” and is used for serial communication with a peripheral, modem (data carrier equipment (DCE)) or data set. Data is written from a master (CPU) over the APB bus to the UART and it is converted to serial form and transmitted to the destination device. Serial data is also received by the UART and stored for the master (CPU) to read back. There is no DMA support on the UART block since it’s contains internal FIFOs. Both UARTs support hardware flow control signals (RTS, CTS, DTR,...
