2.2 Overview
Figure 2-1 shows the building blocks of the CC13x2x7 and CC26x2x7 device platform.
The CC13x2x7 and CC26x2x7 device platform has the following features:
- Arm® Cortex®-M4F processor core
- 48 MHz RC oscillator and 48 MHz crystal oscillator
- 32 kHz crystal oscillator, 32 kHz RC oscillator, or low-power 48 MHz crystal derive clock for timing maintenance while in low-power modes
- Arm® Cortex® SysTick timer
- Nested vectored interrupt controller (NVIC)
- On-chip memory
- 704 kB of Flash with 8 kB of 4-way set-associative cache RAM for speed and low power
- 144 kB of System RAM with configurable retention in 16 kB blocks
- Power management
- Wide supply voltage range
- Efficient on-chip DC/DC converter for reduced power consumption
- High granularity clock gating and power gating of device parts
- Flexible frequency of operation
- Flexible low-power modes allowing low energy consumption in duty cycled applications
- Sensor interface
- Autonomous, intelligent sensor interface that can wake up independently of the System CPU system to perform sensor readings, collect data, and determine if the System CPU must be woken
- 12-bit analog-to-digital converter (ADC) with eight analog input channels
- Low-power analog comparator
- Serial communication interfaces

For applications requiring extreme conservation of power, the CC13x2x7 and CC26x2x7 device platform features a power-management system to efficiently power down the devices to a low-power state during extended periods of inactivity. A power-up and power-down sequencer, a 32-bit sleep timer (an RTC), with interrupt and 144 kB of ultra-low-leakage (ULL) RAM with retention in all power modes positions the MCU perfectly for battery applications.
In addition, the CC13x2x7 and CC26x2x7 device platform offers the advantages of the widely available development tools of Arm®, SoC infrastructure IP applications, and a large user community. Additionally, the microcontroller uses Arm Thumb®-compatible Thumb-2 instruction set to reduce memory requirements and, thereby, cost.
TI offers a complete solution to get to market quickly, with evaluation and development boards, white papers and application notes, an easy-to-use peripheral driver library, and a strong support, sales, and distributor network.
