D-EEPROM – Description


The DEEPROM performs communication and exchanges data between external serial EEPROM Memory and CPU’s RAM memory interface. Its contents are accessible to the CPU in the same manner as a common SRAM memory, but require READY input to expand the time access. Our proprietary core allows to map serial EEPROM in processor memory space and control it as the parallel memory. The controller automatically sends all control instructions and read /write memory locations. As for the CPU, the EEPROM is being connected to it through the DEEPROM. Moreover, it’s visible and controlled as parallel SRAM with long access time. Our unique Core has been designed to operate with popular 25XXX SPI Serial EEPROMs (Atmel, Microchip).
