Several power saving modes provide flexibility for maximum optimization between wakeup latency and power consumption, an especially important consideration in low power applications
Holtek is delighted to announce the release of its new generation Arm® Cortex®-M0+ Microcontroller devices, the HT32F52344/52354 series. These devices are suitable for a wide range of applications such as TFT-LCDs, intelligent door locks, IoT terminal devices, wearable devices, intelligent home appliances and USB game peripherals and so on.
This new series include functions such as a high operating speed of 60 MHz and a single power supply with an operating voltage range of 1.65 V~3.6 V. With regard to memory the devices contain 64/128K bytes of Flash Program Memory and 8K bytes of SRAM Data Memory. The devices also contain a 6-channel PDMA and a 12-channel 1 Mbps SAR A/D Converter. They also provide a CRC16/32 data checking mechanism and a hardware divider. A high resolution PWM generator is also integrated with an input frequency of up to 96 MHz to provide excellent Duty resolution for enhanced and accurate control.
The HT32F52344/52354 devices are supplied in 33/46-pin QFN and 48/64-pin LQFP package types and contain from 26 to 54 GPIO pins. In their low power consumption mode (DeepSleep1/2), the devices support an any-I/O-pin wake-up function. The integrated reference voltage is used for A/D Converter measurement calibration and its power saving mode design makes the devices convenient for use in low-power battery applications.
The Holtek development platform includes an ICE e-Link32 Pro, a full set of peripheral driver firmware libraries, application example source codes, application development handbooks as well as the GNU GCC and make compilation environment. With Holtek’s integrated ISP (In-System Programming) and IAP (In-Application Programming) technology, users will find software upgrade implementation an easy and quick process, thus enhancing the efficiency and flexibility of their products.
