HC32L 110C6PA-TSSOP20TR/TSSOP-20

ARM Cortex-M0 32-bit microcontroller -MCU

Product features

      Low power consumption performance

- 0.5 μA@3V deep sleep mode: Power consumption when all clocks are turned off, power-on reset is effective, IO status is maintained, IO interrupts are effective, and all registers, RAM, and CPU data are saved

- 1.0 μA @3V deep sleep mode + RTC operation

- 6 μA @32.768kHz low-speed operation mode: CPU and peripheral modules run, and programs run from flash

- 20 μA/MHz@3V@16MHz sleep mode: the CPU stops working, peripheral modules run, and the master clock runs

- 120 μA/MHz @3V@16MHz working mode: CPU and peripheral modules run, programs run from Flash

- The ultra-low power consumption wake-up time of -4 μs makes mode switching more flexible and efficient, and the system response more agile

      16K/32K byte Flash memory with erasure and write protection

      2K/4K byte RAM memory with parity check to enhance system stability

      Universal I/O pins (16IO/20pin, 12IO/16pin)
