Fujitsu Microelectronics announces production start of 16LX Microcontroller with embedded Dual-Operation Flash Memory

(PRWEB) February 21, 2004

Fujitsu announces a new 16LX microcontroller to complement its portfolio of microcontrollers with Controller Area Network (CAN) interface. This latest product has been designed for automotive body control and comfort applications. In automatic air-conditioning, light control, seat control and sensor systems the product supports driver or passenger comfort and safety features.

 

Housed in a 48-pin QFP package of a mere 7mm square, this small footprint incorporates the 16LX CPU core and peripherals such as timers, 4ch PWM, 2 UARTs, AD-Converter as well as 64KB of Flash memory and 2KB RAM. Some I/Os feature programmable port levels. In addition to TTL and C-MOS levels, ¬Ďautomotive levels¬í (with VIL = 0.5*Vcc), can be selected. This is a critical feature as ground levels in vehicles often show offsets of several volts.

 

Fujitsu‚Äôs new device, the MB90F897 can be specified for 125¬įC operation and is pin compatible to the MB90385 and MB90455 series. The company now offers more 50 different 16LX CAN products.

 

Fujitsu is actively growing its core competence in embedded Flash technology since the introduction of the first 16-bit microcontroller with single voltage Flash technology and 10K write-erase cycles in 1997. Recent specifications for 100K write/erase cycles or high temperature specifications underline that the process technology has achieved a high level of stability.

 

The new dual-operation Flash technology inherits these feature and expands the functionality: It allows fast EEPROM emulation and reliable self-programming because the 64KB Flash macro is divided into two banks. In each Flash memory bank write, read and erase operation can be performed separately.

 

The smaller bank consists of four sectors of 4KB each. Any sector can be erased individually. Writing to Flash is possible in units of one word.
