Tokyo, August 2, 2001-- Hitachi, Ltd. (TSE: 6501) today announced
the H8/3069F F-ZTATTM microcontroller*,
with large 512-Kbyte flash memory and 16-Kbyte RAM on-chip, as an
addition to the H8/300H Series lineup of 16-bit microcontrollers.
Sample shipments will begin in November 2001 in Japan.
With its large-capacity on-chip flash memory and RAM, the H8/3069F
is suitable for control of storage devices such as CD-R/RW, DVD-ROM/RAM,
and combined CD-RW and DVD-ROM/RAM devices. The provision of on-chip
flash memory also allows program modifications to be carried out on-board,
enabling system development time to be shortened.
Featuring a high-performance 16-bit H8/300H CPU core and a rich set
of peripheral functions that include 16-bit timers, an A/D converter,
DMA controller, and serial interface, and offering a comprehensive
lineup that includes F-ZTAT versions with on-chip flash memory that
enables shorter development times to be achieved, the H8/300H Series
is widely used in the communication, information, OA, and industrial
fields. Among such applications, the use of storage devices such as
CD-R/RW, DVD-ROM/RAM, and HDDs as devices for handling large-volume
multimedia data, including still and moving images, has experienced
rapid growth in recent years.
Hitachi has previously released the H8/3062F, H8/3064F, and H8/3068F,
with on-chip flash memory capacities of 128, 256, and 384 Kbytes,
respectively, as F-ZTAT products for storage device control. But the
increasingly sophisticated functionality of application products,
including the advent of combined CD-RW and DVD-ROM/RAM devices, means
ever larger program sizes, and at the same time there is a demand
for large-capacity on-chip flash memory to enable extended system
development times to be cut.
The H8/3069F has been developed to meet these market needs, offering
the following features around a H8/300H CPU core.
[Product Features]
| (1) |
Largest on-chip memory capacity in H8/300H Series
512 Kbytes of single-power-supply flash memory and 16 Kbytes of
RAM are provided on-chip, allowing storage of a large system program.
In addition, the flash memory programming speed is approximately
three times faster than current products, offering a shorter write
time despite the larger capacity. |

Enhanced flash memory programming method
Flash memory programming methods now inlcude the industry's first
user boot mode in addition to the conventional boot mode and user
programming mode. Previously, the boot program run when the device
is powered on has only operated in a boot mode that initiates
a fixed program that cannot be modified by the user, but in user
boot mode, a user-written program can be run. This makes it possible
to run a program written to meet specific user needs after powering
on, such as selection of the interface to be used, or erasure
of the flash memory.
In addition, the flash memory program/erase control program is
built in as firmware, enabling programming/erasing to be executed
simply by calling this program from the user program. This eliminates
the previous need for a user-written control program, enabling
the application device's system program to be simplified and development
time to be shortened. |

High-speed operation, with a 25 MHz operating frequency
at a power supply voltage of 5 V or 3.3 V
Logic circuits such as the CPU core run at a low voltage of approximately
1.9 V. An on-chip step-down circuit generates a voltage of approximately
1.9 V from a 5 V or 3.3 V external power supply voltage, making
it possible to select the power supply voltage according to the
voltage of the interface used, and to achieve high-speed operation
with a minimum instruction execution time of 80 nanoseconds at
the maximum operating frequency of 25 MHz on either power supply
voltage. |
On-chip peripheral functions include functions suited
to storage device control such as three 16-bit timer channels, four
8-bit timer channels, eight high-precision 10-bit A/D converter channels,
four DMA controller channels, and three serial interface channels.
The following software and hardware products are available to provide
a development environment for the H8/300H Series:
Software: C compiler, assembler, linkage editor, simulator/debugger
Hardware: E6000 realtime emulator
The H8/3069F is available in a 100-pin plastic 0.5 mm pin pitch QFP
or TQFP package. Use of the thin TQFP makes it possible to create slimmer
systems.
Future plans include further extension of the product lineup with the
development of higher-speed models and mask ROM models.
