Part Number: TMS320F28377S
To Whom it may concern
I am currently working with the TMS320F28377s (176 pins) and would like to confirm whether it is suitable for my application under the following conditions:
1. SPI Interfaces
- SPI-A: micro SD card
- SPI-B: multi-slave configuration
* ADC (AD7734: 24-bit, 4 channels) – 3 units, all channels set to 100 Hz sampling rate
* DAC (AD5064: 16-bit, 4 channels) – 1 unit
- SPI-C:
* ADC (AD7172: 24-bit, 2 channels) – 1 unit, all channels set to 400 Hz sampling rate
2. I2C Interface
- RTC (m41t82)
3. UART x 4
- Real-time message communication with other chips
- Each port uses a 2048-word buffer
4. Algorithms
- Temperature PID control: 4 channels
- Flow PID control: 8 channels
5. SD Card File Storage
- Multiple files:
* Calibration-related files
* Log files
* Measurement data files
6. Important Data Storage
- Using 2 Flash sectors
Could you please advise whether the TMS320F28377s is appropriate for these requirements, particularly in terms of memory usage and real-time processing capability? Any recommendations or insights would be greatly appreciated.
Best regards,
