Motor Controller Extends Memory In Automotive Applications

(TDK Corporation)

TDK Corporation expands its Micronas embedded motor controller portfolio with the HVC 4420F, featuring extended flash memory for the drive of small brush-type, stepper, or brushless motors. Designed to provide diagnostics in automotive applications, the controller offers an extension of the flash memory to 64 KB and SRAM to 4 KB. Due to its larger memory and the built-in diagnostic feature set, the HVC 4420F offers the storage capacity and processing capability to execute actions that are unique in the environment of smart actuators.

 

The HVC 4420F is part of the Micronas high-voltage controller family (HVC) for smart actuators. The HVC family combines an ARM® standard microcontroller core with a wide range of additional functions to enable particularly compact and cost-efficient system designs for use in automotive applications and beyond. Powered by a 32-bit CPU core (ARM® Cortex®-M3) with 64 kB flash memory, the HVC 4420F contains, amongst others, timers/counters, interrupt controllers, multichannel ADC, SPI, and enhanced PWMs with diagnosis functions, important for utilization in safety relevant applications. An advanced LIN UART with a LIN 2.x transceiver as well as voltage regulators to connect the device directly to the automotive board net (5.4 V – 18 V) do round up the all-in-one approach. Several power management modes help reducing the current consumption. Various integrated digital and analog circuit units, such as comparators with virtual star point reference, current scaling and an embedded programmable gain amplifier allow users to minimize the number of external components.
