Working Principle

The TMS320F2802PZQ belongs to the TMS320C2xx (Delaware) architecture family, which is designed for 32-bit multi-core processors. The core architecture of the TMS320F2802PZQ is a Harvard architecture featuring an on-chip 32-bit C compiler and a 32-bit RISC CPU. This core set-up enables the processor to rapidly access and execute program instructions from the on-chip internal and external memories. In addition, the TMS320F2802PZQ provides hardware support for interrupts, a wide selection of on-chip peripherals, and specialized core functions.

The 32-bit RISC CPU implements a 3-stage pipeline. The number of byte and halfword instructions the processor can decode per cycle is eight. To reduce power consumption, certain peripherals are placed in “powerdown” mode when not in use, which dynamically reduces the power consumption by allowing the processor to “sleep”. An on-chip innovative watchdog timer keeps the processor from getting stuck in a sleep state.

In terms of memory, the TMS320F2802PZQ supports up to 16MB each of program memory, data memory, and boot memory. Additionally, the on-chip peripheral controllers allow the processor to interface with a wide range of peripherals and external memory configurations. The debug interface provides a way to monitor application activities and helps with debugging the programs.
