Description

The TMS320C57SPGE57, TMS320C5x generation of the Texas Instruments (TI) TMS320 digital signal processors (DSPs) is fabricated with static CMOS integrated circuit technology; the architectural design is based upon that of an earlier TI DSP, the TMS320C25. The combination of advanced Harvard architecture, on-chip peripherals, on-chip memory, and a highly specialized instruction set is the basis of the operational flexibility and speed of the ’C5x‡devices. They execute up to 50 million instructions per second (MIPS).

Features

1. Powerful 16-Bit TMS320C5x CPU

2. 20-, 25-, 35-, and 50-ns Single-Cycle Instruction Execution Time for 5-V Operation

3. 25-, 40-, and 50-ns Single-Cycle Instruction Execution Time for 3-V Operation

4. Single-Cycle 16 × 16-Bit Multiply/Add

5. 224K × 16-Bit Maximum Addressable External Memory Space (64K Program, 64K Data, 64K I/O, and 32K Global)

6. 1K Dual-Access On-Chip Program/Data RAM (DARAM)

7. Full-Duplex Synchronous Serial Port for Coder /Decoder Interface

8. Time-Division-Multiplexed (TDM) Serial Port

9. Hardware or Software Wait-State Generation Capability

10. On-Chip Timer for Control Operations

11. Repeat Instructions for Efficient Use of Program Space

12. Multiple Phase-Locked Loop (PLL)

13. High-Performance Static CMOS Technology

14. IEEE Standard 1149.1†Test-Access Port(JTAG)
