TSPC106
Description
The TSPC106 provides an integrated, high-bandwidth, high-performance, TTL-com-
patible interface between a 60x processor, a secondary (L2) cache or up to a total of
four additional 60x processors, the PCI bus and main memory.
PCI support allows system designers to rapidly design systems using peripherals
already designed for PCI.
The TSPC106 uses an advanced 3.3V CMOS-process technology and maintains full
interface compatibility with TTL devices.
The TSPC106 integrates system testability and debugging features via JTAG bound-
ary-scan capability.

Description
The TSPC106 provides a PowerPC
®
microprocessor CHRP-compliant bridge between
the PowerPC microprocessor family and the PCI bus. CHRP is a set of specifications
that defines a unified personal computer architecture and brings the combined advan-
tages of the Power Macintosh
®
platform and the standard PC environment to both
system vendors and users. PCI support allows system designers to rapidly design sys-
tems using peripherals already designed for PCI and other standard interfaces available
in the personal computer hardware environment. These open specifications make it
easier for system vendors to design computers capable of running multiple operating
systems. The TSPC106 integrates secondary cache control and a high-performance
memory controller. The TSPC106 uses an advanced 3.3V CMOS process technology
and is fully compatible with TTL devices.
The TSPC106 supports a programmable interface to a variety of PowerPC microproces-
sors operating at select bus speeds. The 60x address bus is 32 bits wide; the data bus
is 64 bits wide. The 60x processor interface of the TSPC106 uses a subset of the 60x
bus protocol, supporting single-beat and burst data transfers. The address and data
buses are decoupled to support pipelined transactions.

TSPC106
The TSPC106 provides support for the following configurations of 60x processors and
L2 cache:
•
•
•
Up to four 60x processors with no L2 cache
A single 60x processor plus a direct-mapped, lookaside L2 cache using the internal
L2 cache controller of the TSPC106
Up to four 60x processors plus an externally controlled L2 cache (e.g., the Motorola
MPC2604GA integrated L2 lookaside cache)
The memory interface controls processor and PCI interactions to main memory and is
capable of supporting a variety of configurations using DRAM, EDO, or SDRAM and
ROM or Flash ROM.
The PCI interface of the TSPC106 complies with the PCI local bus specification Revi-
sion 2.1 and follows the guidelines in the PCI System Design Guide Revision 1.0 for
host bridge architecture. The PCI interface connects the processor and memory buses
to the PCI bus to which I/O components are connected. The PCI bus uses a 32-bit mul-
tiplexed address/data bus plus various control and error signals.
The PCI interface of the TSPC106 functions as both a master and target device. As a
master, the 106 supports read and write operations to the PCI memory space, the PCI
I/O space and the PCI configuration space. The TSPC106 also supports PCI special-
cycle and interrupt-acknowledge commands. As a target, the TSPC106 supports read
and write operations to system memory.
The TSPC106 provides hardware support for four levels of power reduction: doze, nap,
sleep and suspend. The design of the TSPC106 is fully static, allowing internal logic
states to be preserved during all power saving modes.
