The CS8421 does not require any soft ware control via a control port. Audio data is input and output through configurable 3-wire input/output ports. Input and output data can be completely asynchronous, synchronous to an external data clock, or the part can operate without any external clock by using an integrated oscillator. Digital audio inputs and outputs can be 32, 24, 20, or 16 bits. The CS8421 is a 32-bit, high-performance, monolithic CMOS stereo asynchronous sample-rate converter. ■ User Object-Code Compatible with all Earlier 68000 Microprocessors ■ 32-Bit, Nonmultiplexed External Address and Data Buses with Synchronous Interface ■ Concurrent IU, FPU, MMU, and Bus Controller Operation Maximizes Throughput ■ Multimaster/Multiprocessor Support via Bus Snooping ■ Low-Latency Bus Acceses for Reduced Cache Miss Penalty ■ Simultaneously Accessible, 4-Kbyte Physical Instruction Cache and 4-Kbyte Physical Data Cache 184 lead Ceramic Quad Flatpack, CQFP (Q4).■ Military Temperature Range: -55☌ to +125☌ The WC32P040 has a 68881/68882-compatible fl oating-point unit (FPU).Ħ8040 FEATURES■ Selection of Processor Speeds: 25, 33MHz The WC32P040 contains dual, independent, demand-paged memory management units (MMUs) for instruction and data stream accesses and independent, 4-Kbyte instruction and data caches. It has a 68030-compatible integer unit (IU) and two independent caches. The WC32P040 is a virtual memory microprocessor employing multiple concurrent execution units and a highly intergrated architecture that provides very high performance in a monolithic HCMOS device.
DESCRIPTIONThe WC32P040 is a 68000-compatible, high-performance, 32-bit microprocessor.
