LPC2460
Fast communication chip
On the LPC2460, I/O pads are powered by the 3.3 V (V
DD(3V3)
) pins, while the
V
DD(DCDC)(3V3)
pins power the on-chip DC-to-DC converter which in turn provides power to
the CPU and most of the peripherals.
Although both the I/O pad ring and the core require a 3.3 V supply, different powering
schemes can be used depending on the actual application requirements.
The first option assumes that power consumption is not a concern and the design ties the
V
DD(3V3)
and V
DD(DCDC)(3V3)
pins together. This approach requires only one 3.3 V power
supply for both pads, the CPU, and peripherals. While this solution is simple, it does not
support powering down the I/O pad ring “on the fly” while keeping the CPU and
peripherals alive.
The second option uses two power supplies; a 3.3 V supply for the I/O pads (V
DD(3V3)
) and
a dedicated 3.3 V supply for the CPU (V
DD(DCDC)(3V3)
). Having the on-chip DC-DC
converter powered independently from the I/O pad ring enables shutting down of the I/O
pad power supply “on the fly”, while the CPU and peripherals stay active.
The VBAT pin supplies power only to the RTC and the Battery RAM. These two functions
require a minimum of power to operate, which can be supplied by an external battery.
When the CPU and the rest of chip functions are stopped and power removed, the RTC
can supply an alarm output that may be used by external hardware to restore chip power
and resume operation.
7.25 System control
7.25.1
Reset
Reset has four sources on the LPC2460: the RESET pin, the Watchdog reset, power-on
reset, and the BrownOut Detection (BOD) circuit. The RESET pin is a Schmitt trigger input
pin. Assertion of chip Reset by any source, once the operating voltage attains a usable
level, starts the Wake-up timer (see description in
Section 7.24.3 “Wake-up timer”
),
causing reset to remain asserted until the external Reset is de-asserted, the oscillator is
running, and a fixed number of clocks have passed.
Once the internal reset is removed, all of the processor and peripheral registers have
been initialized to predetermined values and the LPC2460 continues with booting from an
external static memory.
7.25.2
Boot process
The processor always boots from the off-chip static memory bank 1 executing code from
address 0x8100 0000 (see
Table 5 “LPC2460 memory usage and details”
). During
booting LPC2460’s EMC is configured to access external static memory using 16 data
and 24 address lines. See
Section 11.2 “Suggested boot memory interface solutions”
for
address and data bus interface details.
When booting from an external memory the interrupt vectors are mapped to the bottom of
the external memory. Once booting is over the application must map interrupt vectors to
the proper domain.
