Supported devices:
Philips Semiconductors Inc. LPC2106 16/32 bit
ARM7TDMI-S™
Power supply:
Power supply is made with two LDO adjustable
voltage regulators LM1117. Input voltage should
be 5VDC. Watch out the polarity as schematic
have no input protection diode and reversing the
input power supply will be fatal for LPC2106
microcontroller
RESET:
Reset circuit is made by simple external RC
group. There is possibility to apply RESET
externally on
PIN3
Oscillator:
External crystal 14.7456 Mhz allows very
convenient communication values. This allows
using Philips ISP flash programming utility at
any speed.
PIN assignments:
PIN1 –
GND
PIN2
– DBGSEL – pull low during power up to
enable microcontroller’s JTAG interface
PIN3
– External reset
PIN4
– 3.3V out (power out generated by LPC-
H2106)
PIN5-PIN36
– sequential P0.0 – P0.31
PIN37
– GND
PIN38
– RTCK JTAG re-timed clock.
Implemented
on
certain
ASIC
ARM
implementations the host ASIC may need to
synchronize external inputs (such as JTAG
inputs) with its own internal clock.
PIN39
– Xin – input for external clock
PIN40
– Vin (+5VDC)
