The ADSP-218xN series consists of six single chip microcomputers optimized for digital signal processing applications. 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 provide a great deal of flexibility in the design decision. The ADSP-218xN series offers products from 2 MBits of SRAM to $3.50. Specifically, the series members are -
- ADSP-2184N (4K PM/4K DM)
- ADSP-2186N (8K PM/8K DM)
- ADSP-2185N (16K PM/16K DM)
- ADSP-2187N (32K PM/32K DM)
- ADSP-2189N (32K PM/48K DM)
- ADSP-2188N (48K PM/56K DM)
The ADSP-218xN series offers the highest performance (80Mhz/MIPS) and lowest power consumption (0.55mW/MIP @ 1.8V) within the ADSP-218x portfolio. All series members are offered in a 100-lead LQFP and 144-Ball MBGA packages.
Product Lifecycle Production
At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
Evaluation Kits (1)
The EZ-ICE® serial emulator system provides state-of-the-art emulation for the ADSP-218x family of processors by providing a controlled environment for observing, debugging, and testing activities in a target system. The EZ-ICE connects directly to the target processor through the emulation interface port. Its ease of use, full speed emulation and shielded board will ensure your design process runs smooth.
The debugger available for ADSP-218x EZ-ICE is Analog Devices' VisualDSP++ development environment. All software is sold separately.
