New Products MB90890 Series

●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 SOFTUNETM V3, a FUJITSU integrated software development environment. The SOFTUNE 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 F2MC Family that

Figure 5 Block Diagram

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. ✱
