The ADSP-218xN series consists of six single chip micro- computers 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.
ADSP-218xN series members combine the ADSP-2100 family base architecture (three computational units, data address generators, and a program sequencer) with two serial ports, a 16-bit internal DMA port, a byte DMA port, a programmable timer, Flag I/O, extensive interrupt capa-bilities, and on-chip program and data memory.
ADSP-218xN series members integrate up to 256Kbytes of on-chip memory configured as up to 48Kwords (24-bit) of program RAM, and up to 56Kwords (16-bit) of data RAM. Power-down circuitry is also provided to meet the low power needs of battery-operated portable equipment. The ADSP-218xN is available in a 100-lead LQFP package and 144-Ball Mini-BGA.
Fabricated in a high-speed, low-power, 0.18|ìm CMOS process, ADSP-218xN series members operate with a 12.5ns instruction cycle time. Every instruction can execute in a single processor cycle.
