Communication interfaces (3 of 3)

Feature

Functional description

CAN-FD module (CANFD)

● 2 channels

● Comply with CAN-FD ISO 11898-1 (2015)

● Communication speed

– Classical CAN mode: 1 Mbps

– CAN FD mode:

Nominal bit rate: max. 1 Mbps

Data bit rate: max. 8 Mbps

● Total 192 message buffers (in case frame size is 76 bytes)

– Individual buffers: 64 for TX

– Shared buffers: 128 for TX and RX including FIFO

● Selectable ID type with 11-bit Standard and 18-bit Extended

● Selectable Frame type: Data Frame and Remote Frame

● Up to 256 receive rules

Serial peripheral interface (SPI)

● 4 channels

● SPI transfer facility

– Using the MOSI (master out slave in), MISO (master in slave out), SSL (slave select),

and RSPCK (SPI clock) signals enable serial transfer through SPI operation (four lines)

or clock-synchronous operation (three lines)

– Capable of handling serial transfer as a master or slave

● Data formats

– Switching between MSB first and LSB first

– The number of bits in each transfer can be changed to any number of bits from 8 to 16,

or 20, 24, or 32 bits.

– 128-bit buffers for transmission and reception

– Up to four frames can be transmitted or received in a single transfer operation (with

each frame having up to 32 bits)

● Buffered structure

– Double buffers for both transmission and reception

● RSPCK can be stopped automatically with the reception buffer full for master reception

Expanded serial peripheral interface

(xSPI)

● 2 channels

● Comply with JESD251

● Multiple slave up to 2 slaves (channel 0 only)

● Protocol mode: 1/4/8pin with SDR/DDR

1S-1S-1S, 4S-4D-4D, 8D-8D-8D

● Support OctaFlash, OctaRAM, HyperFlash and HyperRAM

● Protocol mode: 2/4pin with SDR compatible with QSPI

1S-2S-2S, 2S-2S-2S

1S-4S-4S, 4S-4S-4S

● Configurable address length

● Configurable initial access latency cycle

● Support XiP mode

● Support up to 64 MB address space each CS

● Prefetch function for burst-read with low latency

● Outstanding buffer for burst-write with high throughput

● Manual command configurable up to 4 commands

● Output clock/input strobe port timing shift

● Automatic command after released reset: up to 4 commands
