BL35P02 DATASHEET
1．General Description
BL35P02 is a single-chip 8-bit micro-controller. This device integrates a HC05 8-bit CPU core, RAM,
ROM, timer, programmable input/output pins and carrier synthesizer. When in standby status, system will stop
oscillator and remain low power consumption. The BL35P02 is suitable for infrared remote control transmitter
application.

6.3 Crystal Oscillator
6.3.1 High frequency Oscillator
6.3.1
Simplified external crystal/ceramic oscillator circuits are shown in Figure 6.3.1.1. An external crystal or
ceramic oscillation source provides 355KHz~8MHz. The load capacitor Cx which values used in the oscillator
circuit design should include all stray capacitance is necessary, but frequency is more than 3.5MHz, Cx can be
removed. The crystal and components should be mounted as close as possible to the pins for start-up
stabilization and to minimize output distortion.

6.3.2 455KHz Oscillator
Using 455KHz crystal/ceramic oscillation is shown Figure 6.3.2.1，generally OSCI/OSCO must be
connected external 200pF capacitor. Otherwise OSCO can be connected 2KΩ to 5KΩ resistor that can be
used by carbon film resistor.
