Lexington, Mass. Targeting automotive applications, STMicroelectronics is launching its ST7FL family of 8-bit microcontrollers for cost-sensitive car body applications including wipers, climate control, door locking, sunroof and window lift.
Based on ST's ST7 architecture, the microcontroller
includes an EEPROM memory bank of from 1.5- to 8-Kbytes to store configuration parameters with a high level of reliability, thus eliminating the need for external devices, minimizing wiring complexity, and reducing the Printed Circuit Board (PCB)
area. The contents of the programmable memory can be secured against
unauthorized copying by activating a read-out protection mechanism. The MCU also has an internal RC oscillator.
Some devices within the family add embedded peripherals such as a Local
Interconnect Network Serial Communication Interface (LINSCITM) which enables
the smooth implementation of small and cost-effective Local Interconnect
Network (LIN) solutions in the automotive sector. The LIN interface, with
its auto-synchronization feature, is able to work using an internal RC
oscillator as a clock source, thus reducing the need for external
With an extensive range of development utilities, including automotive
evaluation kit for networking, starter kits, SW drivers for easy LIN
implementation, ST says the family enables a very short time to market.
Additionally, the in-circuit programming capability of single-voltage Flash
technology allows devices to be programmed rapidly at the end of the assembly
line, ensuring flexible stock management for end users.
Offered in the 16-pin SO16, 20-pin SO20, and QFN20 lead-free packages, the
ST7FL family fully meets the automotive standards for quality. In production
now, in 10000 unit quantities, the ST7FL39, ST7FL19, and ST7FL09 cost $1.00, $0.85, and $0.70 respectively.
The datasheet is available at datasheet.
