TI Bluetooth low Energy CC2640R2F-Q1 device is an AEC-Q100-compliant wireless microcontroller for low-power Bluetooth Low Energy 4.2 and Bluetooth 5.0 automotive applications.

CC2640R2F is an SoC chip launched by TI that complies with automotive regulations. CC2640R2F-Q1 can be widely used in Passive Entry Passive Start (PEPS), Passive Keyless Entry (PKE), car sharing, parking guidance, smartphone connectivity, and other applications. CC2640R2F-Q1 is one of the few outstanding chips on the market that meets automotive standards and supports Bluetooth 5.0. Titanium chips can be used without secondary development. The RF-BM-4077B2 module with CC2640R2F-Q1 as the core can greatly shorten the customer's development cycle. The RF-BM-4077B2 module has more advantages in smart car applications that require vehicle-level standards or higher requirements.

CC2640R2F-Q1 is a cost-effective 2.4GHz RF device in ultra-low power series. Very low active RF and MCU current and low power consumption mode current consumption ensures a super battery life, so nodes connected to automotive batteries can be powered by small button batteries with low power consumption. The admirable receiving sensitivity and programmable output power provide the industry's top RF performance for the demanding automotive RF environment.

CC2640R2F-Q1 wireless MCU includes a 32-bit Arm ® cortex ® - M3 processor running at 48MHz as the main application processor, and an RF core Arm ® cortex ® - M0.

The main MCU of CC2640R2F efficiently processes RTOS and ble applications. The RF core is mainly used for RF operation and ble protocol stack processing. The product development of ble is generally completed on the app, so there is no need to worry about the operation on the ble protocol stack.

CC2640R2F-Q1 has passed the ACE-Q100 certification, reaching the level 2 temperature range (– 40 ° C to + 105 ° C), in which Q1 represents the aec-q100, and the requirements for active device components in the vehicle specification level standard.

CC2640R2F-Q1 is packaged with 7mm × 7mm vqfn with wettable side. The wettability side helps reduce the cost of the production line and improves reliability by optically inspecting solder joints.

Strictly speaking, if a chip wants to meet the vehicle standard, it must meet many indicators.

1. EMC performance shall be up to standard.

On the one hand, the electromagnetic interference of the equipment to the environment during normal operation cannot exceed a certain limit. On the other hand, the equipment has a certain degree of immunity to electromagnetic interference in the environment.

2. There are also strict requirements for the chip's adaptive temperature.

The operating temperature range of industrial chips is - 40 ℃ to 85 ℃.

The working temperature range of the car gauge chip is - 40 ℃ to 125 ℃.

The vehicle specification level standard emphasizes performance and reliability in low or high temperature and wide range of temperature range.

3. Environmental requirements

La humedad, el moho, el polvo, el agua, la compatibilidad electromagnética y la erosión por gases nocivos suelen superar los requisitos de los productos electrónicos de consumo. Además, el requisito de la capacidad del automóvil para resistir vibraciones e impactos es mucho más alto que el de los productos ordinarios.

4. Confiabilidad

En general, la vida útil del diseño del automóvil es de aproximadamente 200 000 kilómetros en 15 años, que es mucho más larga que el requisito de vida útil de los productos electrónicos de consumo. Bajo los mismos requisitos de confiabilidad, cuantos más componentes y enlaces contenga el sistema, mayores serán los requisitos de confiabilidad de los componentes.

5. Requisitos de coherencia

Para productos automotrices complejos, es definitivamente inaceptable que los componentes con poca consistencia provoquen riesgos potenciales para la seguridad de todo el vehículo.

6. Ciclo de vida del producto

Como un gran producto duradero, el automóvil debe mantener la capacidad de suministro de piezas de posventa durante mucho tiempo. El trabajo de verificación del desarrollo de piezas de automóviles también es enorme, por lo que los fabricantes de vehículos y los proveedores de piezas también necesitan mantener un suministro estable a largo plazo.

El módulo RF-BM-4077B2 con chip CC2640R2F-Q1 tiene un rendimiento sobresaliente en vehículos, campo industrial y MÁS aplicaciones. Su alta calidad puede ayudar al producto a desempeñar un rendimiento superior en entornos hostiles y requisitos técnicos estrictos.

Aquí están las aplicaciones del módulo CC2640R2F-Q1 de la siguiente manera.
