NXP S08QL MCUs offer extreme power efficiency and reduced cost

The S08QL MCU family provides extreme energy efficiency at a range of 1.8 to 3.6V, perfect for cost-effective, battery sensitive, portable, low-power applications.

The S08QL family offers low-power features such as two ultralow-power stop modes, low-power run and wait modes, 6 μs wake-up time, ultra-low-power external oscillator and clock gating registers to disable clocks to unused peripherals.

Supports up to 8 KB of flash. It consists of an 8bit modulo timer, a 16bit timer/PWM, UART, RTC, 12bit ADC and analog comparator. Powered down to 1.8V still is able to operate at maximum 20 MHz.

Key features

• Up to 20 MHz 8-Bit HCS08 central processor unit (CPU)
• Up to 8 KB flash, Up to 512 bytes RAM, Security to prevent unauthorized access to contents
