Product Specifications
Product Lines
Toshiba’s TC222C cell-based ASIC series provides
silicon solutions to meet your design goals for high-
performance and low-power systems. Fabricated on
an advanced 0.3-micron double/triple metal CMOS
process, the TC222C Series offers a choice of many
different array sizes ranging from 59,000 to 2,077,000
usable gates. The TC222C Series is optimized for low
2.0V operation with dual 2.0/3.0V I/O options. The
special cell architecture led to an extremely low power
dissipation rating of 0.09 W/MHz/gate (with a fanout
of 1). For a wide variety of applications, three or more
variations of macrocells are available allowing the
optimum tuning of performance and power. The
placement-and-routing run can be power-driven to
ensure that the result is the lowest power
implementation that meets timing constraints. All these
features help to substantially reduce your chip’s power while
maximizing the critical path speed.

System Application Example
-
Digital Camcorder
-
The high-density and low-power features of the TC222C
Series were essential to successfully implement complex
designs for the DVC. In the application example depicted
below, the TC222C Series turned a five- or seven-piece
chip set for the digital signal processing portion of digital
camcorders into a two- or three-chip set. The TC222C
chips additionally incorporated DRAM chips.
The rewards for designing with the TC222C Series are
obvious. The new DVCs are light and easy to carry while
the previous models were nearly as large as the early
analog camcorders that were hoisted onto the shoulder.
In addition, the TC222C implementation helped to
dramatically extend battery life.
Because customers buying ultraportable devices rank
portability and long battery life at the top of their feature
preferences, the TC222C Series are ideal for these
products.
After the VHS-H and 8-mm Betacam models have long
been the mainstay of consumer-use camcorders, digital
video cameras (DVC) are now coming on the market. The
DVC, expected to become the core equipment in the
multimedia era, combines superior video quality with the
ability to transmit video to a personal computer and to the
Internet.

Integration allows high-performance
specialized blocks for video
compression, etc. to be consolidated
onto the same chip. Operating at 2V,
the TC222C Series reduces power
dissipation in large, densely
populated chips.
The TC222C operates with a 2V core
and offers both 3V and 2V I/Os. The
2V core reduces the power
consumption of your design, while
the 3V and 2V I/O compatibility offers
you flexibility with your system
interface design.
