DDR3/4 and LPDDR2/3/4/4x Combo PHY&MAC

Overview

Key Features

• Support DDR3/DDR4 and LPDDR3/LPDDR4/LPDDR4x
• Support DDR4 up to 3200Mbps speed, LPDDR4/4x up to 4266Mbps
• Support Multiport AMBA AXI2.0 interface, port number, asynchronous or synchronous AXI port, data width, FIFO depth, and command queue depth configurable
• Support DFI4.0 compliant interface between controller and PHY
• Support 2 ranks, max density up to 8GB
• Support automatic temperature monitor and refresh rate adjust
• Support CA, write, read VREF eye training and per-bit de-skew training, write leveling training
• Support Inline BIST and SIPI/LFSR/USER patterns
• Support DDPHY loopback test
• Support fully pin-mux easy for PKG/PCB routing
• Support mask write, write/read DBI
• Support 2T CA timing, CA parity, and gear down mode(DDR4)
• Support ECC (error correcting code), 32/64bit data+8bit ECC, correct 1bit-error and detect 2bit-error(DDR4)

Benefits

• High efficiency Command Queue scheduler to provide maximum bandwidth
• Low latency, DFI PIPE configurable on both controller and PHY sides, AXI async/sync configurable, DFI ratio adjustable with frequency;
• Complex QoS, high urgent, priority-based Round-robin port arbitration, timeout, bandwidth restriction supported
• Support AXI read out of order
• Support dual channel access with independent dual command queue, interleaving processed in controller; (LPDDR4)
• Support per-bank refresh and burst refresh to improve DRAM efficiency; (LPDDR4)
• Support automatic clock gate, and different levels of low power mode
• (1)Doze sleep, automatic power down or self-refresh, controller clock could be closed
• (2)Light sleep, hand shake with SOC, root clock could be closed
• (3)Deep sleep, root clock could be closed and power down, data retention supported in DDRIO
• Support hardware-based DDR frequency switch (DFS), and DFI 1:2/1:1 adjustable with frequency, to reduce latency in low frequency
• Support different power mode in different rank
• Support FSP (Frequency-Set-Point) to change working frequency quickly; (LPDDR4)
