TRAVEO™ T2G 32-bit Automotive MCU

Based on Arm® Cortex®-M7 dual

Functional description

supports Audio-Video Bridging (AVB). The MAC supports standard 6-byte programmable addresses. Module uses

AXI interface for DMA access.

3.3.10

Serial memory interface (SMIF)

In addition to the internal flash memory, CYT4DN supports direct connection to two units of 512 MB of external

flash or RAM memory. This connection is made through either a xSPI or serial peripheral interface (SPI). xSPI

allows connection to HyperFlash and HyperRAM devices, while SPI (single, dual, quad, or octal SPI) can connect

with serial flash memory. Code stored in memory connected through this interface allows execute-in-place (XIP)

operation, which does not require the instructions to be first copied to internal memory, and on-the-fly

encryption and decryption for environments requiring secure external data and code.

3.3.11

Sound subsystem

CYT4DN supports the following:

• Four time-division multiplexing (TDM) interfaces

- Full-duplex transmitter and receiver operation

- Independent transmitter or receiver operation, each in master or slave mode

- Up to 32 channels, each channel can be individually enabled or disabled

• Two pulse code modulation-pulse width modulation (PCM-PWM) interface

- Conversion of PCM audio streaming to PWM signals

- Up to 32-bit output sample resolution

- Supports E- and H-bridge formats

- Dead time insertion

• Up to five sound generator (SG) interfaces

- PWM modulated (amplitude, tone) sound generation

- Separate volume and frequency control (two signals) and combined volume-frequency control (one signal)

formats

•Up to five mixers

- Combines multiple PCM source streams into a single PCM destination stream

- PCM source stream can be gain/volume controlled

- Fixed PCM sample formatting (16-bit pairs)

- LPF support by FIR filter

- Fade-in and Fade-out control for both source and destination PCM streams

• One audio digital-to-analog converter (DAC)

- Programmable sampling rate and frequency control

- Supports stereo (Left and Right)

- Supports CIC filter, FIR filter, Interpolation filter, and Delta-Sigma modulator

-Multi-level DAC

3.3.12

One-time-programmable (OTP) eFuse

CYT4DN contains a 1024-bit OTP eFuse memory that can be used to store and access a unique and unalterable

identifier or serial number for each device. eFuses are also used to control the device life-cycle (manufacturing,

programming, normal operation, end-of-life, and so on) and the security state. Of the 1024 bits, 192 are available

for user purposes.

3.3.13

Event generator

The event generator supports generation of interrupts and triggers in Active mode and interrupts in DeepSleep

mode. The event generators are used to trigger a specific device operation (execution of an interrupt handler, a

SAR ADC conversion, and so on) and to provide a cyclic wakeup mechanism from DeepSleep mode. They provide

CPU-free triggers for device functions, and reduce CPU involvement in triggering device functions, thus reducing

overall power consumption and processing overhead.

3.3.14

Trigger multiplexer

CYT4DN supports connecting various peripherals using trigger signals. Triggers are used to inform a peripheral

of the occurrence of an event or change of state. These triggers are used to affect or initiate some action in other
