50 / 77 page ![]() MPC5602D Microcontroller Data Sheet, Rev. 3.1 Preliminary—Subject to Change Without Notice Electrical characteristics Freescale Semiconductor 50 4.16 Slow internal RC oscillator (128 kHz) electrical characteristics The device provides a 128 kHz slow internal RC oscillator. This can be used as the reference clock for the RTC module.
