Complete system memory solution for ADSP-218X DSP family

DSP, Micros & Memory
STMicroelectronics' DSP System Memory (DSM) device, developed in conjunction with Analog Devices, integrates a large flash memory, a PLD block, I/O ports and essential interface and logic functions. The DSM2180F3 provides a complete system memory solution for the ADSP-218x family of DSPs. It allows larger flash memory with JTAG ISP (in-system programming) to be easily added without additional glue or interface logic, effectively reducing both time-to-market and overall system costs.
The DSM2180F3 provides 128 KB of ISP flash memory - sufficient storage for multiple iterations of program code and/or expanded data storage - configured as eight sectors of 16 KB each. On-chip memory-decode and paging logic allows the DSP to access the flash memory either via Byte DMA, which provides a highly efficient way of reading large blocks of flash memory, or as external data overlay memory, which is more efficient for writing to the flash memory as no DMA channel set-up is required.
In addition, the 16 KB sector size of the DSM2180F3 flash matches the size of the DSP's external data overlay address 'window', making for efficient data management, while the on-chip paging logic gives the DSP access to the entire 128 KB of flash memory. The device's PLD block contains 16 macrocells that can be used to implement functions such as chip-selects for external devices, state-machines, counters, keypad and control panel interfaces, clock dividers, handshake delays and multiplexers, eliminating the need for other small external PLDs and logic devices. The 16 additional I/O pins available on the DSM devices, which can be driven by either the DSP software or by PLD logic, effectively double or triple the current I/O available on the ADSP-218x devices.
The DSM2180F3 provides an ideal system-level solution for products that have constraints on size, EMI levels and power consumption. Configuration is accomplished with a development and programming tool downloadable from the ST website.
