The Embedded I/O Company

TIP302 Multiprotocol Communication IP based on MC68302

Application Information

The TIP302 is an IndustryPack

® compatible module with a

serial communication I/O interface using the Motorola

MC68302 Multiprotocol Communication Processor running

at 25 MHz.

The MC68302 contains a 68K core processor, a micro

coded RISC communication processor, 6 serial DMA

channels, 3 timers, an interrupt controller, 3 independent

full-duplex serial communication controllers (SCCs) and

1152 bytes of on-chip RAM.

The TIP302 provides TTL level interface for all 3 SCC’s of

the MC68302 at the IP I/O connector. A variety of physical

layer standards, such as RS232, RS422, RS485 or ISDN

can be supported by the use of custom transition modules.

Internal microcode in the MC68302 supports a variety of

protocols,

such

as

BISYNC,

HDLC,

SDLC,

UART,

DDCMP, V.110, ISDN (2B+D) and transparent modes.

The TIP302 provides 1 Mbytes of static RAM (SRAM) as

dual-port memory for both, MC68302 code and user data.

The code is downloaded to the SRAM by the IP host CPU

prior to removing the MC68302 reset signal by writing to a

control register. Once the MC68302 reset signal is re-

moved, the MC68302 starts fetching code from the SRAM.

The SRAM, the MC68302 registers and the MC68302 on-

chip RAM are accessible by the MC68302 and the IP host

CPU by arbitration. The local bus arbitration is transparent

to the IP host CPU.

Both the IP host CPU and the MC68302 are capable of

generating interrupts to each other.

For First-Time-Buyers the Engineering Documentation

TIP302-ED is recommended. The Engineering Documen-

tation includes TIP302-DOC, schematics and data sheets.
