LS1028A contains two ARM v8 CortexA72 processor cores
with 32 KB L1-D cache and 48 KB L1-I cache
Features summary
Two 32-bit / 64-bit ARM v8 Cortex-A72 CPUs
- Arranged as single clusters of two cores sharing a 1 MB L2 cache
- Speed Up to 1.3 GHz
- Support for cluster power-gating.
Cache coherent interconnect (CCI-400)
- Hardware-managed data coherency
- Up to 400 MHz
32-bit DDR4 SDRAM memory controller with ECC
Two PCIe 3.0 controllers
One serial ATA (SATA 3.0) controller
Two high-speed USB 3.0 controllers with integrated PHY
Following levels of DTSI/DTS files have been created for the LS1028A
SoC family:
- fsl-ls1028a.dtsi:
DTS-Include file for NXP LS1028A SoC.
- fsl-ls1028a-qds.dts:
DTS file for NXP LS1028A QDS board.
- fsl-ls1028a-rdb.dts:
DTS file for NXP LS1028A RDB board
