(1) Depending on the package size, up to 16 pins can be connected to the Sensor Controller. Up to 8 of
these pins can be connected to analog modules.
6.6 Memory
The flash memory provides nonvolatile storage for code and data. The flash memory is in-system
programmable.
The SRAM (static RAM) can be used for both storage of data and execution of code and is split into two
4-KB blocks and two 6-KB blocks. Retention of the RAM contents in standby mode can be enabled or
disabled individually for each block to minimize power consumption. In addition, if flash cache is disabled,
the 8-KB cache can be used as a general-purpose RAM.
The ROM provides preprogrammed embedded TI RTOS kernel, Driverlib and lower layer protocol stack
software (Bluetooth low energy Controller). It also contains a bootloader that can be used to reprogram
the device using SPI or UART. For CC2640R2Fxxx devices, the ROM contains Bluetooth 4.2 low energy
host- and controller software libraries, leaving more of the flash memory available for the customer
application.
6.7 Debug
The on-chip debug support is done through a dedicated cJTAG (IEEE 1149.7) or JTAG (IEEE 1149.1)
interface.
