NXP Semiconductors S08QL MCU Family
NXP Semiconductors S08QL MCU Family is extremely energy efficient at a voltage range of 1.8 to 3.6V. The S08QL is perfect for cost-effective, battery sensitive, portable, low-power applications. The S08QL family offers low-power features like two ultralow-power stop modes, low-power run and wait modes. Other features include 6μs wake-up time, ultralow-power external oscillator and clock gating registers to disable clocks to unused peripherals. In addition to low-power, the S08QL MCU family supports up to 8KB of flash memory. The MCUs consist of an 8-bit modulo timer, a 16-bit timer/PWM (TPM), UART, RTC, 12-bit ADC and an analog comparator. This family can be powered down to 1.8V and still able to operate at maximum 20MHz CPU speed.
