Specifications of MCIMX508CZK8B

• Core: ARM Cortex A8
• Processor Series: i.MX50

Electrical Characteristics
If the PMIC_RDY input is used and BYPASS_PMIC_VFUNCTIONAL_READY = 0, the i.MX50 will
wait for STBY_COUNT cycles after PMIC_STBY_REQ negation before checking PMIC_RDY status.
Once the STBY_COUNT has expired AND the PMIC_RDY signal has been asserted, the OSCNT counter
begins and the 24MHz oscillator is powered up. After OSCNT expires the processor will enter RUN mode.
If the PMIC_RDY input is not used, the processor will attempt to start the 24 MHz oscillator after
STBY_COUNT expires. So at a minimum, all the supplies necessary to start up the 24 MHz oscillator need
to be powered before STBY_COUNT expires: NVCC_SRTC,VDD1P2, VDD1P8, VDD2P5, VDD3P0.
After STBY_COUNT expires, the OSCNT counter begins and the 24 MHz oscillator is powered up. After
OSCNT expires the processor will enter RUN mode, so all other supplies need to be at the appropriate
operating levels before OSCNT expires.
