1.2 LP3500 Features
• Rabbit 3000
• 512K/128K static RAM and 512K/256K flash memory options.
• 26 digital I/O: 16 protected digital inputs and 10 high-current digital outputs provide
• 8 single-ended or 4 differential analog channels with Vcc monitoring option: 11-bit single-
• 3 PWM outputs.
• Six serial ports
• Battery-backed real-time clock.
• Watchdog supervisor.
Two LP3500 models are available. Their standard features are summarized in Table 1.
Appendix A provides detailed specifications.
The LP3500 can be mounted in two ways. It can be mounted to a panel or on a plastic-
enclosure base, which allows I/O connections to be made using traditional connectors with
0.1" spacing. The LP3500 can also be inverted and mounted directly to mating connectors
on a motherboard of the customer's design. The first approach is appropriate where I/O
connections go directly to devices and switches. The second approach is appropriate
where additional circuitry is incorporated on the motherboard.
