Improved data reliability
Data can be written in the chip without external communication,
eliminating concerns about data garble due to fluctuations in
communications lines caused by external noise.
Table 1 provides a list of available packages in this series,
Fig. 5 is a block diagram, and Fig. 6 shows pin assignments.
Development Environment
The new series is supported by SOFTUNE
TM
V3, a FUJITSU
integrated software development environment. The
S
OFTUNE V3 application software is designed to simplify
programming tasks to meet the diversified needs of
program designers. The hardware is compatible with
MB2140 Series, an emulator for the F
2
MC Family that
permits real-time debugging.
Table 2 lists available development tools.
Typical Applications
The new series is a lineup of 16-bit commodity-grade
microcontrollers tailor-engineered for applications that
require high-speed real-time processing, data rewriting,
or data storage to nonvolatile memory while executing
programs on flash memories. Each device is incorporated
in a compact 48-pin package suitable for system board
installation within a limited mounting space.
