1 Beyond absolute maximum ratings device might be damaged. 2 The device contains an internal voltage regulator to generate the logic and OSC supply out of the I/O supply. The absolute maximum ratings apply when the device is powered from an external source. 3 All digital I/O pins are internally clamped to VSSX and VDDX, VSSR and VDDR or VSSA and VDDA. 4 Those pins are internally clamped to VSSOSC and VDDOSC.
MFR4200 Features
The MFR4200 provides the following features. • The FlexRay protocol according to FlexRay Protocol Working document (PWD) V1.1, with differences described in the MFR4200 Protocol Implementation Document (PID) • Data rate of up to 10 Mbit/s on each of two channels • FlexRay frames with up to 254 payload bytes (padding is used for FlexRay payload data that exceeds 32-byte data size boundary) • One configurable receive FIFO • Configurable counters, status indicators, and interrupts dedicated to error signalling • Measured value indicators for clock synchronization • The status of up to four slots can be observed independently of CC receive message buffers • Configurable error signaling • Fractional macroticks (MT) supported for clock correction • 59 message buffers, each with up to 32 payload bytes • Message buffers configurable with state or event semantics • Each message buffer can be configured as a receive message buffer, as a transmit message buffer (single or double), or as a part of the receive FIFO • Receive background buffers for each channel • The host accesses all buffers by means of three active message buffers (active transmit message buffer, active receive message buffer and active receive FIFO buffer) • Filtering for frame ID, cycle counter, and channel for receive and transmit message buffers • Filtering for frame ID, channel, and message ID for the receive FIFO • Maskable interrupt sources provided over one interrupt line • Two types of host interface: HCS12 interface and asynchronous memory interfaces • Minislot action point offset is configurable • Static slot action point offset is configurable • Hardware selectable clock output to drive external host devices: disabled/4/10/40 MHz • Electrical physical layer interface compatible with dedicated FlexRay physical layer. Industry standard RS485 physical layer interface also available.
