TSPC750A/740A
PowerPC750A/740A RISC MICROPROCESSOR Family
Pid8t–750A/740A Specification
.
DESCRIPTION
The TSPC750A and TSPC740A microprocessor (after named
750A/740A) are low–power implementations of the PowerPC
Reduced Instruction Set Computer (RISC) architecture.
The 750A/740A microprocessors designs are superscalar,
capable of issuing three instructions per clock cycle into six
independent execution units
The 740A/750A microprocessors uses a 2,6/3,3–volts CMOS
process technology and maintains full interface compatibility
with TTL devices.
The 750A/740A provides four software controlable power–
saving modes and a thermal assist unit management.
G suffix
The 750A/740A microprocessors have separate 32–Kbyte,
physically–addressed instruction and data caches and differ
only in that the 750A features a dedicated L2 cache interface
with on–chip L2 tags.
CBGA255 and CBGA360
Ceramic Ball Grid Array
Both are software and bus–compatible with the PowerPC603
and PowerPC604 families, and are fully JTAG compliant.
The TSPC740A microprocessor is pin compatible with the
TSPC603e family.
