7.2 Memory

Nonvolatile (Flash) memory provides storage for RF configurations and is used to store factory calibration data.

The flash memory is in-system programmable and erasable.

The ultra-low leakage system static RAM (SRAM) is used by the transciever for both storage of data and

execution of code. Retention of SRAM contents in Standby power mode is enabled by default and included in

Standby mode power consumption numbers.

The onboard boot ROM contains a serial (SPI and UART) bootloader that can be used for inline production

and/or infield programming of the device.

7.3 Battery and Temperature Monitor

A combined temperature and battery voltage monitor is available in the CC1404P device. The battery and

temperature monitor allows an application to continuously monitor on-chip temperature and supply voltage

and respond to changes in environmental conditions as needed. The module contains window comparators to

interrupt the system CPU when temperature or supply voltage go outside defined windows. These events can

also be used to wake up the device from Standby mode through the Always-On (AON) event fabric.
