ADSP-2187NBSTZ-320 (ANALOG DEVICES)
DSP, Плавающая Точка, 16бит, 80 МГц, 64 КБ, LQFP, 100 вывод(-ов)
The ADSP-2187NBSTZ-320 is a single-chip Digital Signal Processing Microcomputer is pin-compatible and is 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-2187N 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 capabilities and on-chip program and data memory. ADSP-2187N series members integrate up to 256K bytes of on-chip memory configured as up to 48K words (24-bit) of program RAM and up to 56K words (16-bit) of data RAM. Power down circuitry is also provided to meet the low power needs of battery-operated portable equipment.
