DesignWare Universal DDR Protocol Controller (uPCTL)

Search Tools

The DesignWare Universal DDR Protocol Controller (uPCTL) serves the memory control needs of applications with simple transactions that do not require an internal scheduler. The streamlined command based low-latency native interface (NIF) also enables the uPCTL to be integrated with a custom application specific scheduler.

The uPCTL is a bridge between a system-on-chip (SoC) application bus and a PHY for a DDR SDRAM, such as the Synopsys DesignWare DDR PHYs. The uPCTL and the DDR PHY together handle the details of the DDR protocol, allowing the application to access memory via simple on-chip bus read/write requests.

The uPCTL connects to DDR PHYs via a DFI 2.1 interface to create a complete memory interface and control solution. The controller includes software configuration registers, which are accessed through an AMBA 2.0 APB interface.

  • For new designs or for designs with higher speed requirements and greater RAS features, consider the Enhanced Universal DDR Protocol Controller (uPCTL2) or Enhanced Universal DDR Memory Controller (uMCTL2)
  • Join your own scheduler to a single-port enhanced Universal Protocol Controller
  • Support for JEDEC standard DDR2, DDR3, LPDDR/Mobile DDR, LPDDR2 and LPDDR3 SDRAMs
  • DFI 2.1 compliant interface to DDR PHY (DFI 3.1 is backward compatible with DFI 2.1)
  • Data rates up to 2133 Mbps in 1:2 frequency ratio, using a 533 MHz controller clock and 1066 MHz memory clock (dependent on process)
  • Data rates up to 1600 Mbps in 1:1 frequency ratio, using a 800 MHz controller clock and 800 MHz memory clock (dependent on process)
