Both families include a Quad Serial Peripheral Interface (QSPI) with an Execute in Place (XIP) feature, allowing use of high-performance serial flash memories--which are both small and inexpensive, compared with traditional pin-parallel flash--for external memory needs.
The large on-chip RAM combined with the ability to execute code in-place from cost-effective QSPI flash memory removes the need for external SDRAM, enabling low-power, cost- effective embedded display applications.
The part is compatible with SPI[TM], QSPI and MICROWIRE[TM] protocols, as well as DSPs.
