6 / 52 page Rev. C | Page 6 of 52 | September 2009 ADSP-21371/ADSP-21375 external code, executing exclusively from internal ROM. Addi- tionally, the processor is not freely accessible via the JTAG port. Instead, a unique 64-bit key, which must be scanned in through the JTAG or Test Access Port will be assigned to each customer. The device will ignore a wrong key. Emulation features and external boot modes are only available after the correct key is scanned. FAMILY PERIPHERAL ARCHITECTURE The ADSP-21371/ADSP-21375 family contains a rich set of peripherals that support a wide variety of applications, includ- ing high quality audio, medical imaging, communications, military, test equipment, 3D graphics, speech recognition, mon- itor control, imaging, and other applications. External Port The external port on the ADSP-21371/ADSP-21375 SHARC processors provide a high performance, glueless interface to a wide variety of industry-standard memory devices. The 32-bit wide bus (ADSP-21371) may be used to interface to synchro- nous and/or asynchronous memory devices through the use of its separate internal memory controllers: the first is an SDRAM controller for connection of industry-standard synchronous DRAM devices and DIMMs (dual inline memory module), while the second is an asynchronous memory controller intended to interface to a variety of memory devices. Four memory select pins enable up to four separate devices to coexist, supporting any desired combination of synchronous and asyn- chronous device types. Table 3.
