Freescale Semiconductor
6
— Based on and includes all existing features of the Freescale TouCAN module
— Full implementation of the CAN protocol specification version 2.0B
– Standard Data and Remote Frames (up to 109 bits long)
– Extended Data and Remote Frames (up to 127 bits long)
– 0–8 bytes data length
– Programmable bit rate up to 1 Mbit/sec
— Flexible Message Buffers (MBs), totalling up to 16 message buffers of 0–8 byte data length each, configurable as
Rx or Tx, all supporting standard and extended messages
— Unused Message Buffer space can be used as general purpose RAM space
— Listen only mode capability
— Content-related addressing
— No read/write semaphores required
— Three programmable mask registers: global for MBs 0-13, special for MB14, and special for MB15
— Programmable transmit-first scheme: lowest ID or lowest buffer number
— Time stamp based on 16-bit free-running timer
— Global network time, synchronized by a specific message
— Maskable interrupts
Three universal asynchronous/synchronous receiver transmitters (UARTs)
— 16-bit divider for clock generation
— Interrupt control logic with maskable interrupts
— DMA support
— Data formats can be 5, 6, 7 or 8 bits with even, odd or no parity
— Up to 2 stop bits in 1/16 increments
— Error-detection capabilities
— Modem support includes request-to-send (RTS) and clear-to-send (CTS) lines for two UARTs
— Transmit and receive FIFO buffers
I2C module
— Interchip bus interface for EEPROMs, LCD controllers, A/D converters, and keypads
— Fully compatible with industry-standard I2C bus
— Master and slave modes support multiple masters
— Automatic interrupt generation with programmable level
Queued serial peripheral interface (QSPI)
— Full-duplex, three-wire synchronous transfers
— Up to four chip selects available
— Master mode operation only
— Programmable bit rates up to half the CPU clock frequency
— Up to 16 pre-programmed transfers
Fast analog-to-digital converter (ADC)
— Eight analog input channels
— 12-bit resolution
— Minimum 1.125
s conversion time
— Simultaneous sampling of two channels for motor control applications
— Single-scan or continuous operation
— Optional interrupts on conversion complete, zero crossing (sign change), or under/over low/high limit
— Unused analog channels can be used as digital I/O
