JMB321\n3. Functional Description\nJMB321 integrates six high-speed Serial I/O’s, six SATA upper layers, a microprocessor, and other control logic into the chip. JMB321 can work as an 1 to 5-ports Port Multiplier or 5 to 1-port Port Selector with internal embedded firmware without extra external flash needed. But it also can use external flash interface and with proper firmware programming to extend its capability.\n\n3.1 Block Diagram\nFigure 3.1 Function View of JMB321\nData Bus\n\nSATA HDD\n\nSATA 3Gb/Sec PHY\n\nSATA Upper Layer\n\nClock Gen\n\nReset Circuit SATA HDD SATA 3Gb/Sec PHY SATA Upper Layer\n\nGPIO Circuit\n\nSATA HDD\n\nSATA 3Gb/Sec PHY\n\nSATA Upper Layer\n\nFIS Processor\n\nSATA Upper Layer\n\nSATA 3Gb/Sec PHY\n\nHOST BUS ADAPTER\n\nSATA HDD\n\nSATA 3Gb/Sec PHY\n\nSATA Upper Layer\n\nuP\n\nPROM\n\nSATA HDD\n\nSATA 3Gb/Sec PHY\n\nSATA Upper Layer\n\nSRAM\n\nSPI\n\nPort Multiplier\n\nRegister Bus\n\nCopyright © 2013 JMicron Inc.

JMB321\n3.2 Operating Mode 3.2.1 Normal Mode\nWhen the pin XTSTN is tied to “high”, JMB321 works in normal mode. After power on sequence and reset operation, uP executes the programs stored in PROM. PROM program initializes settings of this chip and then, thru SPI bus, starts to load the external program and stores it in SRAM if the external flash is available and valid. If the external program is loaded successfully, it will be executed by uP. Generally, the external firmware is customized program to fulfill various applications. If JMB321 fails to load the external program, JMB321 works as a standard 1 to 5-ports Port Multiplier.\n\n3.2.2 Test Mode\nWhen the pin XTSTN is tied to “low”, JMB321 works in test mode.\n\n3.3 Clock\nThe clock source of JMB321 is from AXIN pin. Clock rate is 25MHz. The internal PLL uses this 25MHz clock to generate various clock frequencies for different internal logic blocks of JMB321.\n\n3.4 Reset\nThere are 2-level reset mechanisms in JMB321, i.e. Chip Reset and Protocol Reset.\n\n3.4.1 Chip Reset\nJMB321 uses XRSTN pin and internal Power-On Reset (POR) for Chip Reset. Chip Reset will initialize entire chip and make all circuit at default state. The micro processor will also restart to execute program from default entry point.\n\n3.4.2 Protocol Reset\nProtocol Reset is from host SATA OOB signal. It is used to reset SATA relative operation. The behavior of Protocol Reset is controlled by firmware code.\n\n3.5 Data Bus\nThe bandwidth of JMB321 internal data bus is 600MB/sec. This high speed bus is enough to support all of the Port Multiplier or Port Selector operations.\n\n3.6 Register Bus\nThrough Register Bus, uP controls and monitors all of the logic components in JMB321.\n\nCopyright © 2013 JMicron Inc.

JMB321\n3.7 Micro Processor\nMicro processor and related data processing circuit mainly will be in charge of . data movement . data comparison . accumulate adding . random number generation Besides, several built-in timers will also help firmware control timing sequence and program flow.\n\n3.8 FIS Processor\nFIS (Frame Information Structure) processor helps micro processor communicate with SATA FIS protocol. The FIS Processor interprets the incoming SATA FIS and generates the outgoing SATA FIS for micro processor.\n\n3.9 SATA Port\nJMB321 is compliant with Serial ATA High Speed Serialized AT Attachment Spec. Revision 3.1. Each SATA port could be configured to be host mode (to connect to HDD) or to be device mode (to controller). Generally, users will just configure only one port to be device mode with other ports in host mode. When a SATA port works under multiplier condition, SATA FIS will be transferred straight between host port and device port, without thru microprocessor. Built-in-self-test (BIST) circuit is implemented in each SATA port. Thru microprocessor, each SATA port will be able to enter testing condition or to generate relevant testing patterns.\n\nCopyright © 2013 JMicron Inc. All rights reserved.

JMB321\n3.10 Port Multiplier Mode\nA Port Multiplier is a mechanism for one active host connection to communicate with multiple devices. A Port Multiplier can be thought of as a simple multiplexer where one active host connection is multiplexed to multiple device connections, as shown below.\n\nPort Multiplier can work under PM-aware or Legacy host controller. With PM-aware host controller, the Port Multiplier’s operation is the same regardless of the switching type used by the host, Command-based switching or FIS-based switching. When JMB321 is at this mode, the SATA ports are configured as: Port 0: device port, connect to HDD 0 Port 1: Port 2: Port 3: Port 4: Port 5: device port, connect to HDD 1 device port, connect to HDD 2 device port, connect to HDD 3 device port, connect to HDD 4 host port, connect to Controller\nNDA Required 2013/09/02\n\nCopyright © 2013 JMicron Inc.

JMB321\n3.11 Port Selector Mode\nPort Selector is a mechanism that allows five different host ports to connect to the same device in order to create a redundant path to that device. Only one host connection to the device is active at a time. A Port Selector can be thought of as a simple multiplexer as shown below.\n\nJMB321 supports only side-band port selection. The active host port is selected by the first successfully OOB linked SATA channel or by a hardware select line, GPIO pin. JMB321 is a protocol-layer port selector. It doesn’t degrade the SATA electrical signals between each pair of SATA link. When JMB321 is at this mode, the SATA ports are configured as: Port 0: device port, connect to HDD Port 1: Port 2: host port, connect to Controller 0 host port, connect to Controller 1\nNDA Required 2013/09/02\n\nCopyright © 2013 JMicron Inc.

JMB321\nPort 3: Port 4: Port 5: host port, connect to Controller 2 host port, connect to Controller 3 host port, connect to Controller 4\n\n3.12 Cascaded Port Multiplier Mode (Optional for the specific part number)\nJMB321 supports to cascade another JMB321 to extend device number. Due to the restrictions of specification, the maximum device number extendable is 15. The requirements of specification are also maintained under this mode, for example, error propagation. The configuration of cascaded port multiplier may look like below:\n\nCopyright © 2013 JMicron Inc. All rights reserved. Data Sheet Revision 1.1\n\nPage 13\n\nNDA Required 2013/09/02\n\n\r\n
