Matching IC resources with application need
To closely match specific automotive application requirements, our custom designed automotive motor controller ICs offer a wide choice of microcontroller cores: 8051 (8bit), CR16 (16bit) and the ARM7 (32bit).
In terms of memory resources flexibility is an important factor too and our custom motor controller IC range provides the option of Flash, both with and without FEC, and Data RAM and Flash sizes to fit the task.
To ensure the most efficient management of power, a range of power supplies are generated internally and are backed by comprehensive sequencing and monitoring resources.
The on-chip motor controller includes a driver for external power FETs and a charge pump. Also integrated is a clock system offering a series of programmable PLLs.
In terms of I/O facilities, general purpose I/Os are high voltage (40V) rated and an integral sensor interface includes both ADC and preconditioning stages. Several automotive system bus interfaces are provided as standard of course and to speed diagnostics all our ICs have an integrated debug interface.
