NEC Electronics Corp.'s 78K0/Kx2 series of 8bit
microcontrollers (MCUs) with up to 128KB of flash
memory are targeted at a wide range of home
appliances, consumer electronic products, industrial
equipment, automotive systems, lighting systems and
sensors. The units employ SuperFlash technology
licensed from Silicon Storage Technology Inc. and are
manufactured in a 0.15µm process.
The series offers memory capacities ranging from 8KB
to 128KB in 30- to 80-pin packages. The MCUs also
boast operating speeds up to 20MHz and power supply
voltages ranging from 1.8V to 5.5V, while reducing
operating current to 2.5mA, less than one-third of
similar mask ROM MCUs. Additionally, all of these
features are available without a cost premium, as
products in the 78K0/Kx2 series have price points
comparable to previous mask ROM products from NEC
manufactured in 0.35µm process technology.
"Eight-bit MCUs are shipping in significant
volume as they become more and more prevalent in
today's appliances and industrial equipment,"
said Yoichi Yano, associate vice president for NEC's
4th Systems Operations Unit.
NEC will offer a service to assist developers with
flash programming, scheduled to start next month for
the 78K0S/Kx1+ series, and in April 2005 for the
78K0/Kx2 series. These services, together with tools
such as on-chip debuggers and flash programmers, will
help reduce the time and cost customers currently
spend on programming and enable approximately 50
percent faster turnaround times compared to similar
mask ROM products, according to the company.
Samples of the 78K0/Kx2 are scheduled to begin
shipping in January 2005. Pricing for individual
products in the 78K0/Kx2 line will vary based on the
configuration. For example, the high-end 78K0/KF2 with
60 KB of flash memory is priced at $5 per unit. Mass
production is scheduled to begin in April 2005. For a
