Texas Instruments TMS320C6205ZHK200

Overview

TMS320C6205ZHK200 from Texas Instruments is a fixed-point digital signal processor (DSP) built on the VelociTI™ VLIW architecture, delivering 1600 MIPS at 200 MHz with eight 32-bit instructions per cycle. It integrates 1 MB on-chip SRAM (512 KB program/cache + 512 KB dual-access data), a 32-bit/33-MHz PCI master/slave interface compliant with PCI Specification 2.2, and two multichannel buffered serial ports (McBSPs) for T1/E1 and AC97 audio interfacing - deployed in telecom baseband processing and industrial real-time control systems.

For engineers reviewing the TMS320C6205ZHK200 datasheet, TMS320C6205ZHK200 pinout, TMS320C6205ZHK200 application, or TMS320C6205ZHK200 equivalent, key selection criteria include its 288-pin MicroStar BGA package, 1.5-V core / 3.3-V I/O voltage scheme, 5-ns instruction cycle time, and PCI 2.2-compliant bus interface with 4-wire EEPROM support.

Technical Context

The TMS320C6205ZHK200 implements an eight-functional-unit VelociTI™ VLIW core: six 32-/40-bit ALUs and two 16-bit multipliers producing 32-bit results, enabling up to two multiply-accumulates (MACs) per cycle (400 MMACS). Its load-store architecture uses 32 general-purpose 32-bit registers split across two register files (A/B), with cross-file data access via dedicated buses.

It features a flexible PLL clock generator supporting CLKIN multipliers of ×1 (bypass), ×4, ×6–×11; a glueless 32-bit EMIF supporting SDRAM, SBSRAM, SRAM, and EPROM; and four-channel DMA with auxiliary channel. The PCI interface provides full 32-bit address/data multiplexing, prefetchable/non-prefetchable memory and I/O space mapping, and integrated FIFOs for efficient bus transfers.

FAQ

What is the maximum operating frequency of the TMS320C6205ZHK200?

The TMS320C6205ZHK200 operates at a guaranteed maximum clock rate of 200 MHz, corresponding to a 5-ns instruction cycle time. This rating is validated across the full commercial temperature range (0°C to 90°C case temperature) and 1.5-V ±0.075-V core supply, as specified in the SPRS106G datasheet Section 6 (Recommended Operating Conditions).

Does the TMS320C6205ZHK200 support PCI Express or only legacy PCI?

The TMS320C6205ZHK200 supports only PCI Specification 2.2 (32-bit/33-MHz parallel bus), not PCI Express. Its PCI interface includes AD[31:0], PCBE[3:0], PFRAME, and PTRDY signals - all defined for parallel PCI signaling - and lacks PCIe-specific lanes, differential pairs, or link training logic.

How is boot configuration handled on the TMS320C6205ZHK200?

The TMS320C6205ZHK200 uses five BOOTMODE pins (XD[4:0]) sampled at reset to select boot source: EMIF CE0, internal program RAM, or 4-wire serial EEPROM. Configuration is latched statically; no runtime reconfiguration is supported, and pull-up/pull-down resistors on these pins define the mode per Table 2 in SPRS106G.

What are the voltage requirements for the TMS320C6205ZHK200 core and I/O supplies?

The TMS320C6205ZHK200 requires a 1.5-V ±0.075-V core supply (DVDD) and a 3.3-V ±0.3-V I/O supply (CVDD). PCI I/O pins tolerate up to 5 V, allowing safe interfacing with legacy 5-V PCI slots; however, CVDD must remain at 3.3 V regardless of PCI bus voltage.

Can the TMS320C6205ZHK200 execute code directly from external SDRAM?

No - the TMS320C6205ZHK200 cannot execute code directly from external SDRAM. Its program memory map reserves external addresses for data access only; instruction fetch is limited to internal program RAM (64K × 16-bit) or cache-backed internal memory. External code execution requires copying to internal RAM first.
