TMS320C5534AZHHA05

The TMS320C5534AZHHA05 is TI’s fixed‑point DSP device from the C553x family, aimed at real‑time signal processing in compact systems. It uses a 16‑bit C55x DSP core with a 40‑bit accumulator, fast hardware multiply‑accumulate, and a Harvard architecture for efficient DSP throughput. It runs from a clock source at tens of MHz, delivering tens of MIPS with a pipelined core and MACs. It includes on‑chip RAM/Flash, a DMA/EDMA controller for high‑bandwidth data transfers, and a rich peripheral set (ADC, DAC, PWM, timers, SPI, I2C, UART, etc.) plus an external memory interface. The AZHHA05 suffix identifies a particular package and temperature grade. Development is supported in TI’s Code Composer Studio (CCS) with DSP libraries and examples, and by other toolchains. Typical applications include motor control, audio preprocessing, sensor data conditioning, and data acquisition. For exact specs (memory sizes, I/O, operating conditions), consult the official datasheet and product folder.
