RCM3305
Low-EMI Rabbit 3000
Spectrum spreader for reduced EMI (radiated emissions)
10/100Base-T, RJ-45, 3 LEDs
512K program (fast SRAM) + 512K data
8 Mbytes
(serial flash)
SPEED (on for 100Base-T Ethernet connection)
USR (user-programmable)
Connection for user-supplied backup battery
(to support RTC and data SRAM)
49 parallel digital I/0 lines:
• 43 configurable I/O
• 3 fixed inputs
• 3 fixed outputs
Startup mode (2), reset in
Can be configured for 8 data lines and
5 address lines (shared with parallel I/O lines), plus I/O read/write
Five 3.3 V, CMOS-compatible ports (shared with I/O)
•
all 5 configurable as asynchronous (with IrDA)
•
3 configurable as clocked serial (SPI)
•
2 configurable as SDLC/HDLC
•
1 asynchronous serial port dedicated for programming
Maximum asynchronous baud rate = CLK/8
A slave port allows the RCM3305/RCM3315 to be used as an
intelligent peripheral device slaved to a master processor, which
may either be another Rabbit 3000 or any other type of processor
Ten 8-bit timers (6 cascadable, 3 reserved for internal peripherals),
one 10-bit timer with 2 match registers
