Freescale understands the challenge of performance within an energy budget and offers a wide portfolio of S08 devices that help you reach target performance levels while minimizing low-power in your design. The S08QB family demonstrates extreme energy-efficiency for ultra-long operating life in battery-powered applications.
Features
- S08 8-bit CPU w/10 MHz bus (20 MHz CPU)
- -40 to 85°C
- Up to 8 KB flash, 512 KB RAM
- Two ultra-low power stop modes
- Vreg with fast start-up time and low-regulation voltage
- Computer operating properly (COP) and LVI with selectable trip point
- 8-channel, 12-bit analog-to-digital converter (ADC)
- Serial communications interface (SCI)
- Precision trimming internal clock source provide 0.2 percent resolution with 2 percent deviation for full operating temperature and voltage
- 16-bit timer with selectable IC, OC or pulse width modulation (PWM)
- Up to 22 GPIO
- The S08QB8 is included in Freescale’s product longevity program, with assured supply for a minimum of 10 years after launch
Energy Efficient Solutions Quick Facts
- 6us wake up time allows an application to wake up, perform task and quickly go back to sleep, thus saving power.
- CPU and peripherals can run with the voltage regulator in low-power mode to allow full functionality at reduced frequency for lower power operation.
- User–selectable peripheral clock gating saves power in run and wait modes.
- Ultra-low-power, real–time counter can be used with low-power oscillator, internal or external clock sources in run, wait and stop modes.
