Holtek announced the release of its new generation Enhanced Touch A/D LCD Flash MCU, the BS67F350C. This new device provides 24 touch keys and has excellent noise immunity. The device has integrated the latest enhanced Touch Key Engine and superior Touch Key algorithms for increased execution efficiency. Its high program capacity and rich system resources make the device suitable for production applications which require additional numbers of touch keys, temperature detection and LCD display, such as thermostats, microwave ovens, electric cookers, dehumidifier etc.
The device can resist a wide range of noise interference, such as power supply noise, RF interference, power supply fluctuations and has passed the CS (Conductive Susceptibility) 10V dynamic testing. The internal 1/3 Bias R-Type and C-Type LCD driver can directly drive LCD panel displays and supports 24 SEG×4 COM, 32 SEG×4 COM and 40 SEG×4 COM.
These features enable a large reduction in the required number of external components resulting in lower costs. As it is pin compatible with the BS67F350 device, it can be a replacement for this without the need to create a new PCB board. The device is supplied in both 48-pin and 64-pin LQFP package types.
The device is suitable to be a master MCU, which together with a suitable power board can implement application products. Holtek provides a development system which includes a full suite of software and hardware functions. Holtek also provides a comprehensive set of touch function firmware libraries, enabling users to get started with touch functions extremely quickly. The hardware development tool is known as the e-Link which works together with an OCDS (On Chip Debug Support) architecture MCU, and which provides users with a means of rapid product development and simulation.
