DUAL SMJ320C40 MULTICHIP MODULE
SGKS001D – JULY 1997 – REVISED OCTOBER 2001

POST OFFICE BOX 1443
HOUSTON, TEXAS 77251–1443
description
The 42 dual C40 multichip module (MCM) contains two SMJ320C40 digital signal processors (DSPs) with 128K
words
× 32 bits (42D) or 256K words × 32 bits (42C) of zero-wait-state SRAMs mapped to each local bus. Global
address and data buses with two sets of control signals are routed externally for each processor, allowing
external memory to be accessed. The external global bus provides a continuous address reach of
2G words.
The dual C40 configuration allows standard microprocessor initialization using the bootstrap loader. Both
reset-vector-control terminals are brought out to external terminals for each processor. A single CLKIN line and
a RESET line feed both processors in parallel, minimizing clock skew and allowing easy synchronization for
interlocked operations.
Communication port 0 of CPU #1 connects to communication port 3 of CPU #2 for direct processor-to-processor
communication.
The IEEE-1149.1 (JTAG) test ports of the C40s are connected serially to allow scan operations and emulation
of the module as a whole. Testability of the 42 adds value and reduces development and support costs. Texas
Instruments offers a wide variety of ANSI/IEEE-1149.1 products and support.
The 42 dual C40 MCM is packaged in a 408-pin ceramic quad flat pack. The 42 dual C40 MCM is available in
both a commercial temperature range (0
°C to 70°C) and a military temperature range (–55°C to 125°C) option.
For additional information when designing for cold temperature operation, please see Texas Instruments
application report 320C3x, 320C4x and 320MCM42x Power-up Sensitivity at Cold Temperature, literature
number SGUA001.
