DL-CC2340-B Transparent Transmission BLE Transceiver Module Base on TI’s CC2340 SPECIFICATION
■DL-CC2340-B is a low-power BLE Module designed base on TI's SimpleLink™ wireless series CC2340R5 Bluetooth® Low Energy Chip. The module has a built-in PCB antenna, a compact size (20PIN, 18*12mm), and a total of 15 I/Os. It is equipped with a full-featured firmware (can be called via AT command), which supports Peripheral & Central integration. Under AT configuration, it can perform operations such as scanning, broadcasting, automatic connection, and service discovery. During connection, changes to PHY, MTU, and connection parameters can be made to better control throughput and low power consumption. Transparent transmission can be achieved through the BLE GATT transport layer for Server and Client, while automatic connection and pre-configuration of connection parameters can be also performed. Your external MCU only needs to achieve transparent transmission of Bluetooth configuration and transparent transmission mode through UART interface, making BLE development easier to get started.
■The TI CC2340R chip uses a 48-MHz Cortex-M0+ kernel, with a running power consumption of only 53μA/MHz, and integrates up to 512KB of flash memory, 36KB of SRAM. It can achieve a low power consumption and superior functional performance. Moreover, this Bluetooth Low Energy module has a built-in 48MHz external high-speed and 32.768Khz external low-speed clock with an accuracy of 10ppm, making BLE connections more stable.
■In terms of RF performance, this DL-CC2340-B Bluetooth module integrates RF balun internally, with simplified RF design, and reduced power consumption. With an optimized harmonic and RF matching, it only consumes 5.1mA, with an RX current of 5.3mA, and a TX power of 0dBm. The typical sensitivity can reach as high as -96.5 dBm @ 1 Mbps, and they can also achieve an output power up to +8 dBm. Its outstanding energy consumption indicators makes it suitable for low-power application scenarios such as battery buttons. In order to meet the limit standards for RF power in various countries, the power of this CC2340 Bluetooth module can be also adjusted (ranging from -21 dBm to+8 dBm).
