Microcontroller Family Overview
Melexis is offering custom and semi-custom microcontrollers for automotive applications. Custom microcon-
trollers provide the most cost affective solution by exactly matching the designers needs. Off-the-shelf micro-
controllers typically force the customer to pay for features they don't need, or don't satisfy all of the system
requirements and drive up the component count. Benefits such as increased reliability and design flexibility are
realized using a custom microcontroller. Typical applications are small system control and smart sensor inter-
faces.
Melexis' custom microcontrollers are based on either an eight or sixteen bit RISC core. These can contain the
exact analog and digital periphery the customer needs. Melexis is also embedding sensors on the same die.
Chopper stabilized Hall effect sensors and temperature sensors are currently available. To withstand the auto-
motive environment, these microcontrollers are designed to withstand an 80V load dump, -40癈 to +150癈 oper-
ating die temperature, 6V to 26V supply and output shorts to ground or the battery.
Current applications include controllers for dashboard indicators, air conditioning, solenoid valve system, heat-
ing system, electric window, sunroof and head cushion position, intelligent relay control, and sensor signal con-
ditioning.
Memory
Versatile memory types and configurations are available. The microcontroller's I/O is entirely up to the cus-
tomer. Melexis has a number of standard digital and analog interfaces available. Custom interfaces can be devel-
oped if needed. Typical implementations include:
MX11 (8 bit core)
MLX16 (16 bit core)

Digital Interfaces
Logic I/O, up to 256 eight-bit ports are possible. The outputs can have high voltage (up to 80V), high current
(up to 300 mA), or current limited capability. Also, digital outputs can have re-circulation diodes for driving
relays.
Other digital function that are available are PWM outputs (0% to 100% duty cycle), timers, UART, watchdog
timer and display interfaces.
Custom digital interfaces or functions can be implemented to meet the customer's needs. The logic can be
designed by the customer and implemented using VHDL or schematic format.
