HC32F052
Features
◾ 64MHz Cortex-M0+ 32-bit CPU platform
◾ HC32F052 series has a flexible power management system
‒ 20 μA @ 3 V Deep-sleep mode: all clocks off, power-on reset active, IO state retention, IO interrupt active, all registers,
RAM and CPU data save state power consumption
‒ 40 μA/ MHz @3 V @64 MHz operating mode: CPU running, running program from
FLASH
‒ 4 μs wake-up time makes mode switching more flexible and efficient, and the system reacts more quickly
◾ 128 K/ 64 K bytes Flash memory, with erase and write protection function
◾ 16K bytes RAM memory with parity check to enhance system stability
◾ General purpose I/O leg (40 IO/ 48 pin,
26 IO/ 32 pin, 23 IO/ 28 pin)
◾ Clock, crystal
‒ External high-speed crystal oscillator 8 ~
24 MHz
‒ External low-speed crystal 32.768 k Hz
‒ Internal high-speed clock 12 MHz
‒ Internal low-speed clock32.8/ 38.4 k Hz
‒ PLL clock up to 64 MHz
‒ Hardware supports internal and external clock calibration and monitoring
