TMS320C5545 BoosterPack Hardware
TMS320C5545A DSP is a new device from TI’s TMS320C55x fixed-point digital signal processor with:
• C55x fixed-point DSP architecture (C5545 reached 120 MHz and C55x reaches up to 200 MHz)
• DSP internal memories
– 64KB dual-access RAM
– 256KB single-access RAM
– 128KB read-only memory
• FFT hardware accelerator
• Four DMA with four channels each (16 channels total)
• Three 32-bit general-purpose timers
• Two embedded multimedia card (eMMC) or secure digital (SD) interfaces
• Four inter-IC sound (I2S) for data transport, universal asynchronous receiver/transmitter (UART), serial
peripheral interface (SPI) with three chip select, master and slave inter-integrated circuit (I2C)
• LCD bridge with asynchronous interface
• 10-bit 3-input successive approximation (SAR) analog-to-digital converter (ADC)
• Device USB port with integrated 2.0 high-speed PHY supports both high and full speed device
• Software compatible with C55x devices
• Three integrated LDOs
• On-chip ROM bootloader
• 118-terminal, 7x7 mm, 0.5mm pitch Pb-free plastic ball grid array (BGA) (ZQW suffix)
NOTE: The TMS320C5545A device used on this BoosterPack is the 100 MHz version.
The CC2650 is a 2.4 GHz multi-standard wireless MCU from TI’s SimpleLink™ ultra-low power portfolio
that includes:
