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.
Note:
In this document, the term “60x” is used to denote a 32-bit microprocessor from the
PowerPC family that conforms to the bus interface of the PowerPC 601®, PowerPC
603™ or PowerPC 604™ microprocessors. This does not include the PowerPC 602™
microprocessor that has a multiplexed address/data bus. 60x processors implement
the PowerPC architecture as it is specified for 32-bit addressing, providing 32-bit effec-
tive (logical) addresses, integer data types of 8, 16 and 32 bits, and floating-point data
types of 32 and 64 bits (single-precision and double-precision).
