SHARC Processor
ADSP-21371/ADSP-21375
SUMMARY DEDICATED AUDIO COMPONENTS High performance 32-bit/40-bit floating point processor
optimized for high performance audio processing
Single-instruction, multiple-data (SIMD) computational
architecture
On-chip memory, ADSP-21371—1M bits of on-chip SRAM
and 4M bits of on-chip mask-programmable ROM
On-chip memory, ADSP-21375—0.5M bits of on-chip
SRAM and 2M bits of on-chip mask-programmable ROM ADSP-21371—S/PDIF-compatible digital audio
receiver/transmitter
ADSP-21371—8 dual data line serial ports that operate at up
to 33 Mbps on each data line — each has a clock, frame
sync, and two data lines that can be configured as either a
receiver or transmitter pair
16 PWM outputs configured as four groups of four outputs
ROM-based security features include
JTAG access to memory permitted with a 64-bit key
Protected memory regions that can be assigned to limit
access under program control to sensitive code
PLL has a wide variety of software and hardware multiplier/divider ratios
Available in a 208-lead LQFP_EP package Code compatible with all other members of the SHARC family
The ADSP-21371/ADSP-21375 processors are available with a …
