Large Capacity Memory Combined with Reduced Power Consumption Make MCU Ideal
for Portable Digital Consumer and Industrial Applications
SAN JOSE, Calif., Embedded Systems Conference, April 3 /PRNewswire/ --
Toshiba America Electronic Components, Inc. (TAEC)* today announced the
availability of a new 32-bit, single-chip MIPS-based(TM) reduced instruction
set computer (RISC) microcontroller (MCU) with 2 megabytes (MB) of on-chip
NANO FLASH(TM) memory. Designated TMP19A64F20AXBG and operating at 54
megahertz, the MCU is targeted at battery-operated digital consumer
applications, including digital video cameras. TAEC will be displaying the
device in booth #1510 at the Embedded Systems Conference Silicon Valley 2006
here this week.
"TMP19A64F20AXBG, our second product based on Toshiba NANO FLASH
technology, integrates 2MB of NANO FLASH memory, the largest memory capacity
currently available in the industry. This high-density embedded memory is a
significant technical milestone that enables the control of large programs
with a single chip," said Roland Gehrmann, business development manager in the
ASSP Business Unit at TAEC.
The TMP19A64F20AXBG integrates the Toshiba TX19A core with its excellent
code efficiency and interrupt responsiveness, 2MB of NANO FLASH memory and 64
kilobytes of random-access memory (RAM). A new backup mode function achieves
reduced power consumption by suppressing current leakage even when in standby
mode. In backup mode, power consumption is only a very low 5 microamperes at
2.7 volts. The backup mode function also supports the real-time clock and a
small amount of RAM. Other built-in functions include a 24-channel by 10-bit
high-speed analog-to-digital converter with a conversion speed of 8.44
microseconds and an 8-channel high-speed serial interface. The device
features an extremely fast multiply/accumulate (MAC) capability of 32 bit by
32 bit plus 64 bit in a single clock cycle.
About Toshiba NANO FLASH Technology
Toshiba NANO FLASH is a new technology for embedded flash MCUs that
combines the best attributes of a NAND flash cell and a NOR peripheral circuit
to create high-density embedded memory with ultra-low power consumption.
Embedded NOR flash technologies generally require substantially more power
than the corresponding mask ROM technology. Since battery life is affected by
the current consumption of the device, this power drain prevents effective use
of NOR flash technology as a new-product launch vehicle or to replace mask ROM
with the NOR flash equivalent in production. To meet these application needs,
Toshiba Corporation developed NANO FLASH technology.
NANO FLASH technology uses a NOR architecture with memory cells connected
in parallel to bit-lanes to achieve the high-speed random access required for
embedded program memory. It employs NAND flash cell technology with Fowler-
Nordheim (FN) tunneling for both program and erase to provide very fast
program and erase times with ultra-low power consumption. In addition,
Toshiba improved the readout circuit and its timing control which diminished
DC current dissipation and allowed low-power consumption. Finally, the
process was changed from a memory process to a logic process in order to embed
the flash memory cells with high-performance CMOS technology.
Pricing and Availability
Samples of the TMP19A64F20AXBG NANO FLASH MCU are available now and the
device is in volume production. Pricing of TMP19A64F20AXBG is $27.00 in
10,000-piece quantities.
A mask ROM version, TMP19A64C1DXBG, is also available with sample
shipments planned to start this month. Pricing of TMP19A64C1DXBG is expected
to be $18.00 in 10,000-piece quantities. Mass production is expected to begin
in June 2006. The combined production volume of the NANO FLASH and mask ROM
versions is expected to total 500,000 pieces per month.
