STMicroelectronics, Inc. Memory DSM2180F3V-15T6

The DSM2180F3V-15T6 from Quarktwin Technology Ltd. is a digital signal processor system memory designed for the Analog Devices ADSP-218X family, operating at a 5V supply. It features 128K bytes of flash memory, which can be utilized for bootloading and data overlay memory. The device supports programmable decoding and paging logic, allowing for efficient access to the flash memory as both byte DMA and external data overlay memory. This memory IC provides up to 16 multifunction I/O pins, enhancing the I/O capabilities of the DSP system. It includes over 3,000 gates of programmable logic device (PLD) with 16 macro cells, enabling the integration of peripheral glue logic and the creation of state machines and other logic functions. The in-system programming (ISP) capability via JTAG allows for quick programming of the entire chip without DSP involvement, facilitating efficient manufacturing and testing processes. The DSM2180F3V-15T6 operates with a memory speed of 90 ns and features a low standby power consumption of 75 µA at 5V. It is available in compact 52-pin PQFP and PLCC packages, making it suitable for space-constrained applications. The device also includes content security features to protect against unauthorized access.
