Original Press Release:
Fujitsu Introduces New 32-Bit MB91F467B Microcontroller; Adds to High-Performance Family Designed for Automotive and Industrial Markets
Delivers Efficient Data Collection, Distribution Needed in Advanced Designs
SUNNYVALE, Calif., April 2 / -- Fujitsu Microelectronics America, Inc. (FMA) today expanded its family of 32-bit RISC-based MCUs with the new MB91F467B. Designed in close cooperation with major automotive customers worldwide, the MB91F467B inherits the high-performance core of Fujitsu's popular and proven MB91460 family, and incorporates powerful peripheral functions and features to support a wide range of automotive and industrial applications.
The MB91F467B incorporates six C-CAN controllers and seven LIN-UARTs, backed up by 40kB data RAM and 1088kB of flash memory with readout protection. The combination of features supports the robust computing power and high integration required in advanced automotive designs, such as automotive gateways, body-control applications and central controller systems. In addition, the controller's external bus interface can be connected to Fujitsu's graphics controllers for use in building full-featured dashboards, driver information, and advanced driver-assistance systems.
"The new MB91F467B microcontroller includes all the critical features required by our automotive customers," said Akio Nezu, senior manager of the Embedded Solutions Business Group, Fujitsu Microelectronics America. "It delivers the efficient data collection, data processing, and distribution that are essential to these designs, along with important power-saving and security features."
Reduced Power, Support for Safety and Security Applications
The MB91F467B includes a 100MHz PLL clock circuit that minimizes power consumption by dynamically switching off unused clock trees. An integrated 32kHz sub-clock oscillator used in conjunction with standby modes such as "stop" and "sleep" adds power-saving capabilities. Security and safety applications are supported by the internal clock supervisory circuit, which automatically switches to an internal RC-oscillator as backup in case of a main clock failure.
The MCU also provides flexible timer architectures and the ability to generate and capture high-precision signals, which are basic requirements for automotive systems. The MB91F467B has 8x16-bit, free-running timers; an 8x16-bit reload timer; and 16 PPG channels. For signal capturing, the chip has a 32-channel, 10-bit ADC, eight ICU, and eight OCU modules.
Availability and Pricing
The MB91F467B, which comes in a 144-pin QFP package, functions over the automotive temperature range and operates on a supply voltage of 3V to 5.5V via its internal voltage regulator.
Engineering samples will be available during the second calendar quarter, accompanied by a full set of development tools such as starter kits, hardware- and software-debuggers, and the third-party supported automotive operating systems AUTOSAR and OSEK. Both versions deliver execution times of 100ns/10 MHz. Sample pricing will start at $13 each.
