According to the level height of automatic gating signal in S2, corresponding PCIE or SATA signals are transmitted respectively to M.2 connector, to realize letter
Number gating.
The PCIE/SATA switchings line switching provides signalling channel, passes through before PCIE/SATA switching line switchings
PCIE and SATA two passes enter, by the control of automatic gating signal, enter the letter that PCIE/SATA switches line switching
Number by passage all the way export, i.e. PCIE and SATA signals only have all the way signal pass through, another road signal is ended by speed-sensitive switch.
The design method of the flexibly M.2 self-identifying of support PCIE and SATA protocol as described above, in S3, can be set and work as
When automatic gating signal is output as high level, PCIE/SATA switches line switching and exports PCIE signal to M.2 connector, on the contrary
SATA signals are exported to M.2 connector.Or when setting the automatic gating signal to be output as low level, PCIE/SATA switching circuits are opened
Close to M.2 connector and export PCIE signal, otherwise SATA signals are exported to M.2 connector.
The PCIE/SATA switchings line switching only provides signalling channel, and cost is relatively low, preferably using NXP's
CBTL04083ABS chips, the chip cost is low, and performance is high, and disclosure satisfy that PCIE and two kinds of agreements of SATA support.
Controlled present invention also offers a kind of device of flexible support PCIE and SATA protocol M.2 self-identifying, including PCIE
M.2, device processed, SATA controller and M.2 connector, the PCIE controllers, SATA controller and are provided between connector
PCIE/SATA switches line switching, and the PCIE controllers, the signal output part of SATA controller are cut with PCIE/SATA respectively
The first signal input part and secondary signal the input connection of thread-changing way switch, PCIE/SATA switch the PCIE/ of line switching
SATA signal output parts are connected with the signal input part of M.2 connector, and the M.2 connector also exports automatic gating signal and arrived
PCIE/SATA switches line switching, and automatic gating signal exports corresponding high level or low according to the device type of M.2 connector
Level.
The device of support PCIE and SATA protocol as described above M.2 self-identifying, it is automatic that the M.2 connector is exported
Gating signal is connected after MOS level shifting circuits with PCIE/SATA switching line switchings, PCIE/SATA switching line switchings
The level height exported according to automatic gating signal transmits corresponding PCIE or SATA signals to M.2 connector, and PCIE/SATA is cut
Thread-changing way switch uses NXP CBTL04083ABS chips.
The beneficial effects of the present invention are：
1st, the design method and device of a kind of M.2 self-identifying for supporting PCIE and SATA protocol of the invention, are solved existing
There is the limitation for M.2 only supporting the hardware design of single agreement to bring, in actual application environment, using this hardware design
Method, available for different types of M.2 storage medium is supported, realizes the application of the different storage controls of collocation.
2nd, hardware design methods of the invention and device, it is to avoid support different M.2 to deposit on the basis of secondary development
Storage media, realizes the M.2 automatic identification of PCIE and SATA protocol, reduces construction cycle and development cost, add production
