TOKYO ELECTRON DEVICE announces the release of
LSI TE7740RPF with extended I/O for car navigation systems
and an automotive AEC-Q100 compliant qualification

– Provides flexible and efficient product development using a single chip with integrated I/O functions –

Yokohama, Japan, April 22, 2014 - Tokyo Electron Device Limited (TED) announces the launch of the new LSI TE7740RPF with extended I/O and an automotive AEC-Q100* compliant qualification for in-car ICs. TED began the release of sample products on April 22 under its own brand name “inrevium.”

The high functionalization of car navigation systems in recent years, especially high-end models, means that the number of I/O functions is increasingly insufficient when only the CPU’s built-in I/O functions are used. With LSI TE7740RPF, I/O functions such as SPI (up to 6 MHz CPI clock frequency) and UART (up to 3 Mbps baud rate), which are required for car navigation systems, are integrated into a single chip. This allows for a direct connection with a CPU bus through the 8 bit asynchronous interface and resolves the I/O function insufficiency problem of car navigation systems.

With LSI TE7740RPF, required interface functions and universal I/O ports can be selected using a register setting. It flexibly accommodates customer systems and realizes more efficient product development.

LSI TE7740RPF is automotive AEC-Q100 qualification compliant and meets strict in-car quality requirements. It is suitable for in-car infotainment devices such as car navigation systems.

TED has been providing extended I/O LSIs with various I/O functions since the 1990s. The LSIs are installed in various devices, such as MFPs, projectors and terminal devices. TED offers a wide lineup of products to match various applications. It plans to expand its lineup of these long-term stable I/O products.
