Texas Instruments High-Performance Analog Embedded - Embedded - DSP (Digital Signal Processors) - TMS320C51PZ80 TMS320C51PZ80

The TMS320C51PZ80 is a 16-bit digital signal processor (DSP) from the TMS320C5x series, designed for high-performance applications. It features a powerful 16-bit CPU capable of executing instructions in single cycles, with execution times of 20, 25, 35, and 50 nanoseconds for 5V operation, and 25, 40, and 50 nanoseconds for 3V operation. The processor supports a maximum addressable external memory space of 224K vó 16 bits, which includes 64K for program, 64K for data, 64K for I/O, and 32K for global memory. The TMS320C51PZ80 includes various on-chip memory options, such as 2K, 4K, 8K, 16K, and 32K vó 16-bit single-access program ROM, and 1K, 3K, 6K, and 9K vó 16-bit single-access program/data RAM. It also features a full-duplex synchronous serial port for coder/decoder interfaces, a time-division-multiplexed serial port, and an on-chip timer for control operations. The device is designed with low power dissipation in mind, operating at 47 mA at 5V with a 40 MHz clock, and offers multiple power-down modes. The TMS320C51PZ80 is suitable for applications requiring efficient processing of digital signals, with capabilities for modular design and upward compatibility with earlier TMS320 DSPs. It is available in multiple packaging options, including a 100-pin thin quad flat package.
