320VC5421

The 320VC5421 fixed-point digital signal processor (DSP) is a dual-core solution running at 200-MIPS performance. The 5421 consists of two DSP subsystems capable of core-to-core communications and a 128K-word zero-wait-state on-chip program memory shared by the two DSP subsystems. Each subsystem consists of one 54x DSP core, 32K-word program/data DARAM, 32K-word data SARAM, 2K-word ROM, three multichannel serial interfaces, xDMA logic, one timer, one APLL, and other miscellaneous circuitry.

Features of the 320VC5421 are:(1)Controlled Baseline-  One Assembly/Test Site, One Fabrication Site; (2)Extended Temperature Performance of-40°C to 85°C; (3)Enhanced Diminishing Manufacturing Sources (DMS) Support; (4)Enhanced Product-Change Notification; (5)Qualification Pedigree; (6)200-MIPS Dual-Core DSP Consisting of Two Independent Subsystems; (7)Each Core Has an Advanced Multibus Architecture With Three Separate 16-Bit Data Memory Buses and One Program Bus; (8)40-Bit Arithmetic Logic Unit (ALU) Including a 40-Bit Barrel-Shifter and Two 40-Bit Accumulators Per Core; (9)Each Core Has a 17-Bit × 17-Bit Parallel Multiplier Coupled to a 40-Bit Adder for Non-Pipelined Single-Cycle Multiply/ Accumulate (MAC) Operations.

The absolute maximum ratings of the 320VC5421 can be summarized as:(1)Supply voltage I/O range, DVDD - 0.5 V to 4.0 V ; (2)Supply voltage core range, CVDD - 0.5 V to 2.4 V; (3)Supply voltage analog PLL range, AVDD- 0.5 V to 2.4 V; (4)Input voltage range, VI -0.5 V to DVDD + 0.5 V; (5)Output voltage range, Vo - 0.5 V to DVDD + 0.5 V ; (6)Operating case temperature range, TC-40°C to 85°C; (7)Storage temperature range Tstg - 65C to 150°C.
