Holtek launches 32 bit MCUs based on ARM
cortex processor core
Holtek has announced its entry into the 32-bit MCU market
with the release of a new 32-bit MCU device series. Known
as the HT32F125x series, and using an ARM Cortex-M3 core,
these new 32-bit general type Flash devices, include features
such as a high operating speed of up to 72MHz (90 DMIPS),
a single power supply with an operating voltage range of
2.7V~3.6V and an industrial temperature range of -40 Deg
C to 85 Deg C.
The HT32F125x series devices contain 8K~32K bytes of Flash
Program Memory and 2K~8K bytes of SRAM Data Memory together
with an 8-channel 12-bit 1Msps high speed A/D converter
and multiple newly designed General Purpose Timer Modules.
These Timer Modules can implement functions such as Timer/Counter,
Capture, Compare, Single Pulse Output and various PWM modes.
HT32F125x supports multiple power management modes, a power
reset (POR), multi-level low voltage and brownout detection
etc. Operated both from external crystal and internal RC
oscillators providing both 8MHz and 32MHz fully internal
oscillator frequencies.
The devices are supplied in 48-pin LQFP package types and
contain up to 32 GPIO pins. Additional functions include
fully integrated real time clock, operational amplifiers
and comparators, USART interface, SPI interface, I2C interface
etc. Application areas for this new range of devices could
include medical products, computer peripherals, home appliances,
personal health care products and portable devices etc.
