Hitachi Embedded Microcontrollers

H8S/2646F - Member of the 2nd

generation new high performance, H8S/CAN range of Microcontrollers from Hitachi


4 th Generation Performance improvement with adoption of

0.18µm process

Hitachi introduced recently its latest 4th generation embedded Flash technology. Adoption of the 0.18µm process resulted in a quantum leap in Flash memory access speed and CPU operating speed.


� Compared with the 0.8µm process, memory access speed is 10 times faster and CPU operating frequency is 5 times speedier.� Besides, programming time has been significantly reduced: it only takes about 10 seconds to program 512Kbyte Flash of a 4th generation microcontroller !

New features coming with the 4th generation F-ZTAT such as integrated firmware and an extra user boot mat. (Boot mat is a sector reserved for storing once only a boot program of PLC and becomes protected flash like a ROM)


4th G Flash - Key Features and Benefits

•High integration, up to 1 MB Embedded Flash •High speed, 12.5 ns read access time at 80 MHz


•Fast programming (about 2.5s for 128 Kbytes) which significantly reduces end-of-line programming time Integrated firmware which considerably simplifies handling

•Extra boot mat which enables user-specific bootstrapping, via any com-port

•Wide temperature range, up to –40/+125 °C


RELIABILITY Products are planned that guarantee 10,000 times re-writing of the Flash memory. The majority of today's products guarantee 100 times re-writing, some already 1,000 times. The data retention period is guaranteed for 10 years as well.

Benefits of Internet Connectivity

�Remote monitoring, control or updating of PLC programs from anywhere using a web browser. (username and password access

requirements protect the system from unauthorized access)


PLCs, which are Internet-ready -can be remotely programmed, monitor or control PLC-controlled equipment via the Internet at any time. PLC can also dial up via modem to get connected to the Internet, send an email or to save data to a remote location.
