JMB320 Description
JMB320 is a highly integrated single chip. It integrates three high-speed Serial I/O’s, three SATA upper layers, a microprocessor, SRAM, PROM, a highly efficient data bus and other control logic into the chip. JMB320 can work as an 1 to 2-ports Port Multiplier or 2 to 1-port Port Selector using internal embedded firmware without extra external flash needed.
