RabbitCore RCM3200
Notes
1. When using pins 33–34 on header J1 to drive LEDs, you must use an external buffer to
drive these external LEDs. These pins are not connected on the RCM3220, which does
not have the LEDs installed.
2. The VRAM voltage is temperature-dependent. If the VRAM voltage drops below about
1.2 V to 1.5 V, the contents of the battery-backed SRAM may be lost. If VRAM drops
below 1.0 V, the 32 kHz oscillator could stop running. Pay careful attention to this volt-
age if you draw any current from this pin.
Locations R45, R46, R53, R57, and R74 allow the population of 0
resistors (jumpers)
that will be used to enable future options. These locations are currently unused.
