Description
The CC2620 device is a wireless MCU targeting ZigBee® RF4CE remote control applications, both
controller and target node.
The device is a member of the CC26xx family of cost-effective, ultralow power, 2.4-GHz RF devices. Very
low active RF and MCU current and low-power mode current consumption provide excellent battery
lifetime and allow for operation on small coin cell batteries and in energy-harvesting applications.
The CC2620 device contains a 32-bit ARM Cortex-M3 processor that runs at 48 MHz as the main
processor and a rich peripheral feature set that includes a unique ultralow power sensor controller. This
sensor controller is ideal for interfacing external sensors and for collecting analog and digital data
autonomously while the rest of the system is in sleep mode. Thus, the CC2620 device is ideal for ZigBee
RF4CE remote controls with features like voice, motion, RF-IR hybrid remotes, and qwerty keyboards and
STB/target nodes with capacitive touch.
The IEEE 802.15.4 MAC is embedded into ROM and runs partly on an ARM Cortex-M0 processor. This
architecture improves overall system performance and power consumption and frees up flash memory for
the application.
Software stack support for this device includes: ZigBee RF4CE stack (RemoTI) which is available free of
charge from www.ti.com.

The frequency accuracy of the Real Time Clock (RTC) is not directly dependent on the frequency accuracy of the 32-kHz RC Oscillator.
The RTC can be calibrated to an accuracy within ±500 ppm of 32.768 kHz by measuring the frequency error of RCOSC_LF relative to
XOSC_HF and compensating the RTC tick speed. The procedure is explained in Running Bluetooth® Low Energy on CC2640 Without

For smaller coin cell batteries, with high worst-case end-of-life equivalent source resistance, a 22-µF VDDS input capacitor (see

Main CPU
The SimpleLink CC2620 Wireless MCU contains an ARM Cortex-M3 (CM3) 32-bit CPU, which runs the
application and the higher layers of the protocol stack.
The CM3 processor provides a high-performance, low-cost platform that meets the system requirements
of minimal memory implementation, and low-power consumption, while delivering outstanding
computational performance and exceptional system response to interrupts.
CM3 features include the following:
• 32-bit ARM Cortex-M3 architecture optimized for small-footprint embedded applications
• Outstanding processing performance combined with fast interrupt handling
• ARM Thumb®-2 mixed 16- and 32-bit instruction set delivers the high performance expected of a 32-bit
ARM core in a compact memory size usually associated with 8- and 16-bit devices, typically in the
range of a few kilobytes of memory for microcontroller-class applications:
– Single-cycle multiply instruction and hardware divide
– Atomic bit manipulation (bit-banding), delivering maximum memory use and streamlined peripheral
control
– Unaligned data access, enabling data to be efficiently packed into memory
• Fast code execution permits slower processor clock or increases sleep mode time
• Harvard architecture characterized by separate buses for instruction and data
• Efficient processor core, system, and memories
• Hardware division and fast digital-signal-processing oriented multiply accumulate
• Saturating arithmetic for signal processing
• Deterministic, high-performance interrupt handling for time-critical applications
• Enhanced system debug with extensive breakpoint and trace capabilities
• Serial wire trace reduces the number of pins required for debugging and tracing
• Migration from the ARM7™ processor family for better performance and power efficiency
• Optimized for single-cycle flash memory use
• Ultralow-power consumption with integrated sleep modes
• 1.25 DMIPS per MHz
6.4
RF Core
The RF Core contains an ARM Cortex-M0 processor that interfaces the analog RF and base-band
circuitries, handles data to and from the system side, and assembles the information bits in a given packet
structure. The RF core offers a high level, command-based API to the main CPU.
The RF core is capable of autonomously handling the time-critical aspects of the radio protocols (802.15.4
RF4CE) thus offloading the main CPU and leaving more resources for the user application.
The RF core has a dedicated 4-KB SRAM block and runs initially from separate ROM memory. The ARM
Cortex-M0 processor is not programmable by customers.

SWRS178C – FEBRUARY 2015 – REVISED JULY 2016
Sensor Controller
The Sensor Controller contains circuitry that can be selectively enabled in standby mode. The peripherals
in this domain may be controlled by the Sensor Controller Engine which is a proprietary power-optimized
CPU. This CPU can read and monitor sensors or perform other tasks autonomously, thereby significantly
reducing power consumption and offloading the main CM3 CPU.
The Sensor Controller is set up using a PC-based configuration tool, called Sensor Controller Studio, and
potential use cases may be (but are not limited to):
• Analog sensors using integrated ADC
• Digital sensors using GPIOs, bit-banged I2C, and SPI
• UART communication for sensor reading or debugging
• Capacitive sensing
• Waveform generation
• Pulse counting
• Keyboard scan
• Quadrature decoder for polling rotation sensors
• Oscillator calibration
NOTE
Texas Instruments provides application examples for some of these use cases, but not for all
of them.
The peripherals in the Sensor Controller include the following:
• The low-power clocked comparator can be used to wake the device from any state in which the
comparator is active. A configurable internal reference can be used in conjunction with the comparator.
The output of the comparator can also be used to trigger an interrupt or the ADC.
• Capacitive sensing functionality is implemented through the use of a constant current source, a timeto-digital converter, and a comparator. The continuous time comparator in this block can also be used
as a higher-accuracy alternative to the low-power clocked comparator. The Sensor Controller will take
care of baseline tracking, hysteresis, filtering and other related functions.
• The ADC is a 12-bit, 200-ksamples/s ADC with eight inputs and a built-in voltage reference. The ADC
can be triggered by many different sources, including timers, I/O pins, software, the analog
comparator, and the RTC.
• The Sensor Controller also includes a SPI–I2C digital interface.
• The analog modules can be connected to up to eight different GPIOs.
The peripherals in the Sensor Controller can also be controlled from the main application processor.

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.
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 (802.15.4 MAC). It also contains a bootloader that can be used to reprogram the device using
SPI or UART.
6.7
Debug
The on-chip debug support is done through a dedicated cJTAG (IEEE 1149.7) or JTAG (IEEE 1149.1)
interface.

The Brown Out Detector is disabled between recharge periods in STANDBY. Lowering the supply voltage below the BOD threshold
between two recharge periods while in STANDBY may cause the BOD to lock the device upon wake-up until a Reset/POR releases it.
To avoid this, it is recommended that STANDBY mode is avoided if there is a risk that the supply voltage (VDDS) may drop below the
specified operating voltage range. For the same reason, it is also good practice to ensure that a power cycling operation, such as a
battery replacement, triggers a Power-on-reset by ensuring that the VDDS decoupling network is fully depleted before applying supply
voltage again (for example, inserting new batteries).
In active mode, the application CM3 CPU is actively executing code. Active mode provides normal
operation of the processor and all of the peripherals that are currently enabled. The system clock can be
any available clock source (see Table 6-2).
In idle mode, all active peripherals can be clocked, but the Application CPU core and memory are not
clocked and no code is executed. Any interrupt event will bring the processor back into active mode.
In standby mode, only the always-on domain (AON) is active. An external wake event, RTC event, or
sensor-controller event is required to bring the device back to active mode. MCU peripherals with retention
do not need to be reconfigured when waking up again, and the CPU continues execution from where it
went into standby mode. All GPIOs are latched in standby mode.
In shutdown mode, the device is turned off entirely, including the AON domain and the Sensor Controller.
The I/Os are latched with the value they had before entering shutdown mode. A change of state on any
I/O pin defined as a wake from Shutdown pin wakes up the device and functions as a reset trigger. The
CPU can differentiate between a reset in this way, a reset-by-reset pin, or a power-on-reset by reading the
reset status register. The only state retained in this mode is the latched I/O state and the Flash memory
contents.

CC2620
SWRS178C – FEBRUARY 2015 – REVISED JULY 2016
www.ti.com
The Sensor Controller is an autonomous processor that can control the peripherals in the Sensor
Controller independently of the main CPU, which means that the main CPU does not have to wake up, for
example, to execute an ADC sample or poll a digital sensor over SPI. The main CPU saves both current
and wake-up time that would otherwise be wasted. The Sensor Controller Studio enables the user to
configure the sensor controller and choose which peripherals are controlled and which conditions wake up
the main CPU.
6.9
Clock Systems
The CC2620 supports two external and two internal clock sources.
A 24-MHz crystal is required as the frequency reference for the radio. This signal is doubled internally to
create a 48-MHz clock.
The 32-kHz crystal is optional. The low-speed crystal oscillator is designed for use with a 32-kHz watchtype crystal.
The internal high-speed oscillator (48-MHz) can be used as a clock source for the CPU subsystem.
The internal low-speed oscillator (32.768-kHz) can be used as a reference if the low-power crystal
oscillator is not used.
The 32-kHz clock source can be used as external clocking reference through GPIO.
6.10 General Peripherals and Modules
The I/O controller controls the digital I/O pins and contains multiplexer circuitry to allow a set of peripherals
to be assigned to I/O pins in a flexible manner. All digital I/Os are interrupt and wake-up capable, have a
programmable pullup and pulldown function and can generate an interrupt on a negative or positive edge
(configurable). When configured as an output, pins can function as either push-pull or open-drain. Five
GPIOs have high drive capabilities (marked in bold in Section 4).
The SSIs are synchronous serial interfaces that are compatible with SPI, MICROWIRE, and Texas
Instruments synchronous serial interfaces. The SSIs support both SPI master and slave up to 4 MHz.
The UART implements a universal asynchronous receiver/transmitter function. It supports flexible baudrate generation up to a maximum of 3 Mbps .
Timer 0 is a general-purpose timer module (GPTM), which provides two 16-bit timers. The GPTM can be
configured to operate as a single 32-bit timer, dual 16-bit timers or as a PWM module.
Timer 1, Timer 2, and Timer 3 are also GPTMs. Each of these timers is functionally equivalent to Timer 0.
In addition to these four timers, the RF core has its own timer to handle timing for RF protocols; the RF
timer can be synchronized to the RTC.
The I2C interface is used to communicate with devices compatible with the I2C standard. The I2C interface
is capable of 100-kHz and 400-kHz operation, and can serve as both I2C master and I2C slave.
The TRNG module provides a true, nondeterministic noise source for the purpose of generating keys,
initialization vectors (IVs), and other random number requirements. The TRNG is built on 24 ring
oscillators that create unpredictable output to feed a complex nonlinear combinatorial circuit.
The watchdog timer is used to regain control if the system fails due to a software error after an external
device fails to respond as expected. The watchdog timer can generate an interrupt or a reset when a
predefined time-out value is reached.

SWRS178C – FEBRUARY 2015 – REVISED JULY 2016
The device includes a direct memory access (µDMA) controller. The µDMA controller provides a way to
offload data transfer tasks from the CM3 CPU, allowing for more efficient use of the processor and the
available bus bandwidth. The µDMA controller can perform transfer between memory and peripherals. The
µDMA controller has dedicated channels for each supported on-chip module and can be programmed to
automatically perform transfers between peripherals and memory as the peripheral is ready to transfer
more data. Some features of the µDMA controller include the following (this is not an exhaustive list):
• Highly flexible and configurable channel operation of up to 32 channels
• Transfer modes:
– Memory-to-memory
– Memory-to-peripheral
– Peripheral-to-memory
– Peripheral-to-peripheral
• Data sizes of 8, 16, and 32 bits
The AON domain contains circuitry that is always enabled, except for in Shutdown (where the digital
supply is off). This circuitry includes the following:
• The RTC can be used to wake the device from any state where it is active. The RTC contains three
compare and one capture registers. With software support, the RTC can be used for clock and
calendar operation. The RTC is clocked from the 32-kHz RC oscillator or crystal. The RTC can also be
compensated to tick at the correct frequency even when the internal 32-kHz RC oscillator is used
instead of a crystal.
• The battery monitor and temperature sensor are accessible by software and give a battery status
indication as well as a coarse temperature measure.
6.11 Voltage Supply Domains
The CC2620 device can interface to two or three different voltage domains depending on the package
type. On-chip level converters ensure correct operation as long as the signal voltage on each input/output
pin is set with respect to the corresponding supply pin (VDDS, VDDS2 or VDDS3). lists the pin-to-VDDS
mapping.

Depending on the product configuration, CC26xx can function either as a Wireless Network Processor
(WNP—an IC running the wireless protocol stack, with the application running on a separate MCU), or as
a System-on-Chip (SoC), with the application and protocol stack running on the ARM CM3 core inside the
device.
In the first case, the external host MCU communicates with the device using SPI or UART. In the second
case, the application must be written according to the application framework supplied with the wireless
protocol stack.

7 Application, Implementation, and Layout
NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI's customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
7.1
Application Information
Very few external components are required for the operation of the CC2620 device. This section provides
some general information about the various configuration options when using the CC2620 in an
application, and then shows two examples of application circuits with schematics and layout. This is only a
small selection of the many application circuit examples available as complete reference designs from the
product folder on www.ti.com.
Figure 7-1 shows the various RF front-end configuration options. The RF front end can be used in
differential- or single-ended configurations with the options of having internal or external biasing. These
options allow for various trade-offs between cost, board space, and RF performance. Differential operation
with external bias gives the best performance while single-ended operation with internal bias gives the
least amount of external components and the lowest power consumption. Reference designs exist for
each of these options.

8 Device and Documentation Support
8.1
Device Nomenclature
To designate the stages in the product development cycle, TI assigns prefixes to all part numbers and
date-code. Each device has one of three prefixes/identifications: X, P, or null (no prefix) (for example,
CC2620 is in production; therefore, no prefix/identification is assigned).
Device development evolutionary flow:
X
Experimental device that is not necessarily representative of the final device's electrical
specifications and may not use production assembly flow.
P
Prototype device that is not necessarily the final silicon die and may not necessarily meet
final electrical specifications.
null
Production version of the silicon die that is fully qualified.
Production devices have been characterized fully, and the quality and reliability of the device have been
demonstrated fully. TI's standard warranty applies.
Predictions show that prototype devices (X or P) have a greater failure rate than the standard production
devices. Texas Instruments recommends that these devices not be used in any production system
because their expected end-use failure rate still is undefined. Only qualified production devices are to be
used.
TI device nomenclature also includes a suffix with the device family name. This suffix indicates the
package type (for example, RSM).
For orderable part numbers of the CC2620 device in the RSM or RGZ package types, see the Package
Option Addendum of this document, the TI website (www.ti.com), or contact your TI sales representative.

The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.
(2)
Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability
information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that
lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between
the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight
in homogeneous material)
(3)
MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
(4)
There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device.
(5)
Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation
of the previous line and the two combined represent the entire Device Marking for that device.
(6)
Lead/Ball Finish - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead/Ball Finish values may wrap to two lines if the finish
value exceeds the maximum column width.

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other
changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest
issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and
complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale
supplied at the time of order acknowledgment.
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily
performed.
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered
documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
TI is not responsible or liable for any such statements.
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use
of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of
non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
