Clock Management

The module has a 32 MHz main crystal oscillator and 32.768 kHz RTC crystal oscillator.

• Option : 32.768KHz RTC Crystal

Peripherals

The general GPIO is organized as one port with up to 30 I/Os enabling access and control of up to 30 pins through one port. Each GPIO can be accessed individually with the following user-configurable features.

◉ Input/output direction
◉ Output drive strength
◉ Internal pull-up and pull-down resistors
◉ Wake up from high or low-level triggers on all pins
◉ Trigger interrupt on all pins
◉ All pins can be used by the PPI task/event system.

The maximum number of pins that can be interfaced through the PPI at the same time is limited by the number of GPIOTE channels
◉ All pins can be individually configured to carry serial interface or quadrature demodulator signal.

The transceiver receives and transmits data directly to and from system memory for flexible and efficient packet data management. The module’s transceiver has the following features.

◉ General modulation features
◉ GFSK modulation
◉ Data whitening
◉ On-air data rates (250 kbps/1 Mbps/2 Mbps)
◉ Transmitter with programmable output power of +4 dBm to -20 dBm, in 4 dB step

◉ Baseband controller
◉ Easy DMA RX and TX packet transfer directly to and from RAM
◉ Dynamic payload length
◉ On-the-fly packet assembly/disassembly and AES CCM payload encryption
◉ 8 bit, 16 bit and 24 bit CRC check

The timer runs on the high-frequency clock source (HFCLK) and includes a four- bit (1/2X) pre-scaler that can divide the timer input clock from the HFCLK controller. Clock source selection between PCLK16M and PCLK1M is automatic according to TIMER base frequency set by the pre-scaler.
The TIMER base frequency is always given as 16 MHz divided by the pre-scaler value.
The PPI system allows a TIMER event to trigger a task of any other system peripheral of the device. The PPI system also enables the TIMER task/event features to generate periodic output and PWM signals to any GPIO. The number of input/outputs used at the same time is limited by the number of GPIOTE channels.

The temperature sensor measures die temperature over the temperature range of the device with 0.25-degree resolution.
The SPI is implemented with Easy DMA support for ultra-low power serial communication from an external SPI master. Easy DMA in conjunction with hardware-based semaphore mechanisms removes all real-time requirements associated with controlling the SPI slave from a low-priority CPU execution context.
The TWI slave with Easy DMA (TWIS) is compatible with I2C operating at 100 kHz and 400 kHz. The TWI transmitter and receiver implement Easy DMA.
The Universal asynchronous receiver/transmitter with Easy DMA (UART) offers fast, full-duplex, asynchronous serial communication with built-in flow control (CTS, RTS) support in hardware at a rate up to 1 Mbps, and Easy DMA data transfer from/to RAM.
The ADC supports up to eight external analog input channels, depending on package variant. It can be operated in a one-shot mode with sampling under software control, or a continuous conversion mode with a programmable sampling rate.
The analog inputs can be configured as eight single-ended inputs, four differential inputs or a combination of these. Each channel can be configured to select AIN0 to AIN7 pins, or the VDD pin. Channels can be sampled individually in one-shot or continuous sampling modes, or using scan mode, multiple channels can be sampled in sequence. Channels can also be oversampled to improve noise performance. The I2S (Inter-IC Sound) module, supports the original two-channel I2S format, and left or right- aligned formats. It implements Easy DMA for sample transfer directly to and from RAM without CPU intervention. The I2S peripheral has the following main features :
◉ Master and Slave mode
◉ Simultaneous bi-directional (TX and RX) audio streaming
◉ Original I2S and left- or right-aligned format
◉ 8, 16 and 24-bit sample width
◉ Low-jitter Master Clock generator

Recommended Soldering Profile

The data here is given only for guidance on solder and has to be adapted to your process and other reflow parameters for example the used solder paste.
The paste manufacturer provides a reflow profile recommendation for his products.

Opposite side re-flow is prohibited due to module weight. Devices will withstand the specified profile and will withstand up to 1 re-flows to a maximum temperature of 260 degree.
The re-flow soldering profile may only be applied if the COMO-N832C resides on the PCB side looking up. Heat above the solder eutectic point, while the COMO- N832C is mounted facing down, may damage the module permanently
