GENERAL DESCRIPTION The ADSP-218xN series consists of six single chip microcomputers optimized for digital signal processing applica tions. The high-level block diagram for the ADSP-218xN series members appears on the previous page. All series members are pin-compatible and are differentiated solely by the amount of on-chip SRAM. This feature, combined with ADSP-21xx code compatibility, provides a great deal of flexibility in the design decision. PERFORMANCE FEATURES 12.5 ns Instruction Cycle Time @1.8 V (Internal), 80 MIPS Sustained Performance Single-Cycle Instruction Execution Single-Cycle Context Switch 3-Bus Architecture Allows Dual Operand Fetches in Every Instruction Cycle Multifunction Instructions Power-Down Mode Featuring Low CMOS Standby Power Dissipation with 200 CLKIN Cycle Recovery from Power-Down Condition Low Power Dissipation in Idle Mode INTEGRATION FEATURES ADSP-2100 Family Code Compatible (Easy to Use Algebraic Syntax), with Instruction Set Extensions Up to 256K Bytes of On-Chip RAM, Configured as Up to 48K Words Program Memory RAM Up to 56K Words Data Memory RAM Dual-Purpose Program Memory for Both Instruction and Data Storage Independent ALU, Multiplier/Accumulator, and Barrel Shifter Computational Units Two Independent Data Address Generators Powerful Program Sequencer Provides Zero Overhead Looping Conditional Instruction Execution Programmable 16-Bit Interval Timer with Prescaler 100-Lead LQFP and 144-Ball Mini-BGA
