DescriptionThe TS68C429AMFB/C is designed as one kind of CMOS ARINC 429 multichannel receiver / transmitter (MRT) that is an enhanced version of the EF 4442 and is designed to be connected to the new 16- or 32-bit microprocessors, especially these of the Atmel TS68K family. This device contains five parts: the microprocessor interface unit (MIU), the logical control unit (LCU), the interrupt control unit (ICU), the receiver channel unit (RCU) and the transmitter channel unit (TCU).
Features of the TS68C429AMFB/C are:(1)8 independent receivers (Rx); (2)3 independent transmitters (Tx); (3)full TS68K family microprocessor interface compatibility; (4)16-bit data-bus; (5)ARINC 429 interface: 1 and 0 lines, RZ code; (6)support all ARINC 429 data rate transfer and up to 2.5 Mbit/s; (7)multi label capability; (8)parity control: odd, even, no parity, interrupt capability; (9)independent programmable frequency for Rx and Tx channels; (10)8 messages FIFO per Tx channel; (11)independent interrupt request line for Rx and Tx functions; (12)vectored interrupts; (13)daisy chain capability; (14)direct addressing of all registers; (15)test modes capability; (16)20 MHz operating frequency; (17)self-test capability for receiver label memories and transmit FiFO; (18)low power: 400 mW.
The absolute maximum ratings of the TS68C429AMFB/C can be summarized as:(1)Supply Voltage: -0.3 to +7.0 V;(2)Input Voltage: -0.3 to +7.0 V;(3)Max Power Dissipation: 400 mW;(4)Operating Temperature M suffix: -55 to +125 °C;(5)Storage Temperature: -55 to +150 °C;(6)Junction Temperature: +160 °C;(7)Lead Temperature: +270 °C.
The electrical characteristics of this TS68C429AMFB/C can be summarized as:(1)Input High Voltage: 2.25 to Vcc+0.3 V;(2)Input Low Voltage: -0.5 to 0.8 V;(3)Output High Voltage (except IRQRX, IRQTX: open drain outputs): 2.7 V;(4)Output Low Voltage: 0.5 V;(5)Output Sink Current: 8 mA;(6)Input Leakage Current: ±20 A;(7)Dynamic Current: 65 mA.
