According to the latest "Bluetooth Market Latest Information 2023" released by the Bluetooth SIG in 2023, forecast data from market research agency ABI Research shows that the Bluetooth market will achieve high growth in the next five years, and the annual shipments of Bluetooth devices will remain Strong growth momentum, expected to reach 7.6 billion units by 2027, with a compound annual growth rate of 9%, driven by continued strong growth in peripherals, single-mode low-power Bluetooth device shipments will grow over the next five years to the present more than twice.
Figure 1 Bluetooth market trends
TI's fourth-generation low-power Bluetooth SoC—CC2340, aims to combine high-quality radio frequency, low-power performance and low starting price. CC2340 integrates wireless functions of low-power Bluetooth, ZigBee and private 2.4GHz protocols, and is available in two versions. CC2340R5 provides 512kB Flash/36kB SRAM and 26 general-purpose IO ports, and CC2340R2 provides 256 kB Flash/28 kB ARAM and 12 general-purpose IO ports. IO port, supports OTA function, configures rich peripheral resources, and provides peripheral communication interfaces such as UART, SPI, I2C, timer, temperature sensor, battery voltage detection, analog comparator and ADC analog-to-digital converter, etc. We are committed to providing users with wireless communication application platforms in the fields of smart home, medical, industrial control and automobiles at lower prices.
Figure 2 CC2340 features
The CC2340 has the industry's best standby current of less than 710 nA, about 40% lower than the market average, while delivering output power up to +8 dBm, while also allowing engineers to extend RF performance and connectivity range. In addition, the CC2340 series features an integrated RF balun, enabling simpler designs with fewer external components, resulting in cost savings. The CC2340's reduced standby current helps extend battery life, extending the life of coin cell batteries to up to 10 years in wireless applications such as electronic shelf labeling systems and tire pressure monitoring systems.
The CC2340 series has an operating temperature range of -40ºC to 125ºC and can provide stable and highly reliable wireless interconnection quality in complex and harsh working environments. In addition, the CC2340 series products also provide automotive-grade AEC-Q100 versions.
CC2340 is small in size. The CC2340R5 version is available in a 5mm × 5mm QFN40 package, and the CC2340R2 version is available in a 4mm × 4mm QFN24 package. The small size and integrated balanced-unbalanced transformer help realize the design of space-constrained applications.

Typical application scenarios
1. Bluetooth-based TPMS (Tire Pressure Monitoring System)
The Chinese government mandates the installation of TPMS or TPWS in vehicles. Statistics from the China Association of Automobile Manufacturers show that China's domestic car sales will reach 26.864 million units in 2022, a year-on-year increase of 2.1%, of which new energy vehicle sales will reach 6.887 million units, with a market share of Reaching 25.6%, a year-on-year increase of 93.5%, new energy vehicles have gradually entered a period of comprehensive market expansion.
The Bluetooth-based TPMS (Tire Pressure Monitoring System) can realize high tire pressure/alarm, high tire temperature alarm, and air leakage alarm functions. It can prevent flat tires, reduce tire wear, save crude oil, and improve driving safety.

CC2340’s competitiveness in the TPMS market:
► Supports AEC-Q100 certification and PPAP reporting at 125℃;
► Excellent power consumption management, battery life of more than 10 years;
► Supports BLE long-distance communication with coded PHY;
► High security engine;
► Support various wake-up methods (timer, external GPIO wake-up);
► Automatic location detection based on signal strength indication (RSSI) (optional);
► Meet the needs of the development of Internet of Vehicles.
2.PEPS (keyless entry, keyless start) system (car side and key side)
Bluetooth has begun to be widely used in automotive PEPS systems and has grown very rapidly. PEPS front-mounted Bluetooth has driven the rapid growth of Bluetooth-enabled car keys. Security positioning needs have driven UWB+Bluetooth PEPS systems to enter the high-end car market. In the future, Bluetooth Alliance high-precision ranging ( HADM) technology is a better alternative to UWB.

CC2340’s competitiveness in PEPS car and key end:
► Provide 125°C AEC-Q100 certification and PPAP report;
► Extremely low power consumption, supporting up to 10 years of battery life;
► Excellent mobile phone Bluetooth compatibility, providing compatibility test reports and testing tools;
► Maximum transmit power +8 dbm, industry-leading sensitivity of -102 dbm;
► Security features such as secure boot with root of trust ensure car security.
3. Medical equipment, building automation and consumer electronics products
Because the CC2340 is small in size and easy to use, it can be easily integrated into products. The extremely low power consumption can extend the service life of the battery, allowing users to use the product with peace of mind. The wider temperature range and powerful performance can ensure that it can operate in complex environments. It provides reliable connections at low cost, making the final product affordable and high-quality.
► Medical devices: The price, low power consumption and RF performance of CC2340 make it highly attractive for designs such as CGM (continuous glucose monitor), insulin pumps and medical sensor patches.
► Building automation: Smart home control centers can take full advantage of the CC2340 MCU’s wireless protocol support and output power range up to +8 dBm.
► Electronic consumer products: The small size allows the finished product to be more refined and fashionable, the extremely low power consumption allows long-term stable operation on a single charge, and the low cost allows daily products to integrate Bluetooth to provide intelligence.
