Hitachi Releases 16-Bit Single-Chip H8S/2214F Microcontroller for Bluetooth- enabled application
- Allowing shorter development period and smaller, lower-cost product for Bluetooth- enabled application -
Hitachi, Ltd. (TSE: 6501) today announced the 16-bit single-chip H8S/2214F  microcontroller
 for use in products that support the Bluetooth  network technology, providing wireless 
interconnection of mobile phones, notebook PCs, and similar devices.  Sample shipments will
 begin in August 2000 in Japan.

The H8S/2214F, employing Hitachi's highest performance 16-bit microcontroller H8S CPU core, 
is the baseband controller for Bluetooth, following the H8S/2238F currently in production.
With the recent growth in the market for mobile phones, notebook PCs, digital still cameras,
and similar portable information products, attention is now being focused on Bluetooth as 
a  wireless network technology for linking such products.  The Bluetooth standard, standardized
by the Bluetooth SIG*1, provides for a technology achieving a maximum data transmission speed 
of 1 Mbits/sec with approximately up to 10 m, using the radio band at 2.4 GHz.  Initial shipments 
of products incorporating the Bluetooth standard are anticipated during this year.

In September 1999, Hitachi, Ltd. announced to collaborate with Silicon Wave ,Inc of the USA 
to provide total solutions offering baseband controllers,  RF transceiver chip-sets and 
system development support.  Silicon Wave develops and supplies the RMC (Radio Modem Controller)
product family as RF transceivers and Hitachi develops and supplies the baseband controller.

Hitachi has previously released the 16-bit microcontroller H8S/2238F, with on-chip 256-kbyte
flash memory and 16-kbyte RAM, as a Bluetooth baseband controller, and is now supplying this
product to the market.

The  H8S/2214F offers more compact memory, with on-chip 128-kbyte flash memory and 12-kbyte
RAM.  The provision of on-chip flash memory means that  changes in the Bluetooth standard and
data modifications can be handled with ease, enabling development times to be reduced. 
At the same time, the pin arrangement is fully compatible with the H8S/2238F, and address and 
function compatibility has also been maintained for peripheral functions, making it possible
to use boards and software developed for the H8S/2238F.

The H8S/2214F is capable of a fast 16 MHz maximum operating speed at an operating voltage of
2.7 V to 3.6 V.  It includes a UART*2 capable of asynchronous serial transfer at a maximum 
data transmission speed of 720 kbits/sec, as required by the Bluetooth standard, and high-speed
serial data communication at 
1 Mbits/sec can easily be achieved by use of the DTC*3 and DMAC*4.  The comprehensive set of 
on-chip peripheral functions also includes a 3-channel 16-bit timer, single-channel watchdog
timer, and single-channel D/A converter, making it possible to create compact Bluetooth
-compatible products at low cost.
The package lineup comprises two 100-pin plastic TQFPs (0.5 mm pin pitch and  0.4 mm pin pitch) 
and a 112-pin CSP, enabling Bluetooth products to be kept small and slim.

The Bluetooth-oriented device lineup will be further extended in the future, with the
development of a mask ROM version (H8S/2214) and a model with a USB*5 and other peripheral
 functions on-chip.

Notes:	1.The Bluetooth SIG (Special Interest Group), formed in 1998, currently
	  includes over 1,500 companies, including Hitachi, with a core group of nine 
	  promoter companies.

	2.UART (Universal Asynchronous Receiver Transceiver): A transmission/reception
	  circuit for asynchronous serial communication.

	3.DTC (Data Transfer Controller): A DTC is started by an interrupt, and can perform 
	  data transfer instead of the CPU.  Transfer information is located in internal RAM,
	  enabling a greater number of channels to be used.

	4.DMAC (Direct Memory Access Controller): A function or device that performs control
	  for direct data transfer, instead of the CPU, from memory to memory or between memory 
	  and a peripheral device.

	5.USB (Universal Serial Bus): A serial bus interface for connecting PC peripheral 
	  devices, replacing the previous RS-232C interface, and offering higher speed and 
	  commonality with the keyboard interface, etc.

< Development Environment >

The H8S Series C compiler, assembler, linkage editor, librarian, simulators, debuggers, etc.,
can be used as the user software development environment on widely used personal computers and 
workstations.  In addition, a variety of emulators, including the E6000 realtime emulator, are
available as hardware support tools.

< Typical Applications >
