MB88F332 Indigo

MB88F332 'Indigo' is Fujitsu's first sprite-based Graphics Controller. MB88F332 is a 180nm embedded flash CMOS device, which targets automotive application fields, especially state-of-the-art systems, CID (Central Information Display) and RSE (Rear Seat entertainment) systems. The need for expensive framebuffer VRAM memory is eleminated as graphics processing is done entirely on a line-based scheme. A suite of 5V MCU peripherals such as SMC (Stepper Motor Controllers), PWMs (Pulse Width Modulators) and ADCs (Analog-Digital Converters) is integrated to enable the realization of competitive systems. A new highlight in the MB88F332 'Indigo' device is an implementation of Inova Semiconductor's highspeed APIX® (Automotive/Advanced Pixel Link) interface.

Other features include automatically animated special sprites which provide a high degree of creativity for optical designs, runtime data decompression (for the expansion of run-length encoded data, such as a company logo used as a splash screen at system start-up time). A built-in data signature calculation feature ensures data integrity as required for strict ASIL (Automotive Safety Integrity Level) level conformance. A programmable, embedded TCON (Timing Controller) unit makes it possible to connect the device directly to almost any TFT (RSDS or TTL) panel.

MB88F332 'Indigo' is available in a low-cost LQFP package with an extended temperature range.
