8-bit MCU
CM6144
This product is a high-speed and low-power 1T cycle 8051-core 8-bit enhanced FLASH microcontroller chip, which is faster and more efficient than the traditional 8051.
Higher.
The maximum operating frequency is 12MHz, and 16K bytes of FLASH ROM, 1K bytes of EEPROM-LIKE and 768 bytes of RAM (internal RAM 256B plus) are integrated on the chip.
On the external RAM 512B), a high-resolution touch module (up to 26 channels) and a high-precision 12-bit ADC module (up to 26 channels) are integrated inside.
Equipped with a 1MHz RC oscillator and a low-frequency 32k RC oscillator, it contains 26 bidirectional GPIO ports, Two-wire debugging interface and programming interface at most.
It has three 16-bit timers (in which timer2 supports external 32768Hz crystal), 4-channel 16-bit common-period PWM0, and 16-bit high-low level independent control.
PWM1/2, 2 UART, 1 SPI and 1 IIC, and 4-level optional LVD, watchdog timer and other functions are integrated internally.
