PRODUCTION DATA
The CC27xx devices provide 2xUART, 2xSPI, 1xI2C, 1xCAN-FD , and 1xI2S serial peripherals.
The UART module implements universal asynchronous receiver and transmitter functions. They support flexible baud-rate generation up to a maximum of 3Mbps and IRDA SIR mode of operation.
The SPI module supports the SPI controller and peripherals up to 12MHz with configurable phase and polarity.
The I2C module communicates with devices compatible with the I2C standard. The I2C interface can handle 100kHz and 400kHz operation and can serve as both controller and target.
The CAN-FD module communicates with devices supporting Classic CAN (1Mbps) and CAN Flexible Data (FD) (up to 5Mbps) modes. CAN-FD supports faster data speed, higher data capacity (up to 64B payload size per CAN frame), and dynamic switching between different data rates and longer or shorter messages; thereby, enabling several system operational advantages compared to classic CAN.
The I2S interface handles digital audio and can also interface with pulse-density modulation microphones (PDM).
The I/O controller (IOC) 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 fixed manner over DIOs. 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, open-drain, or open-source.
Some GPIOs have high-drive capabilities, which are marked in bold in RHA (6mm × 6mm) Pinout, 0.5mm Pitch (Top View).
VDDIO split rail I/O supply enables using a different I/O supply rail compared to the main VDDS supply rail. This enables applications to interface with other system components at a different voltage level compared to the main VDDS power supply level. GPIOs supplied by VDDIO and VDDS supplies are listed in orange or blue respectively in RHA (6mm × 6mm) Pinout, 0.5mm Pitch (Top View). The voltage rails supplied on VDDS and VDDIO pins can ramp up and down in any order, independent of each other, and any combination of VDDS and VDDIO supplies being unpowered can be supported indefinitely. This simplifies the system-level power supply design, where it is not needed to control the availability or ramp up/down sequence of these supplies at the VDDIO and VDDS pins.
