LPC2104/2105/2106

Single-chip 32-bit microcontrollers

[1]

Typical ratings are not guaranteed. The values listed are at room temperature (+25

°C), nominal supply voltages.

[2]

Internal rail.

[3]

External rail.

[4]

Including voltage on outputs in 3-state mode.

[5]

VDD(3V3) supply voltages must be present.

[6]

3-state outputs go into 3-state mode when VDD(3V3) is grounded.

[7]

Accounts for 100 mV voltage drop in all supply lines.

[8]

Allowed as long as the current limit does not exceed the maximum current allowed by the device.

[9]

Minimum condition for VI = 4.5 V, maximum condition for VI = 5.5 V.

[10] Applies to P0[31:22].

[11] SPI is enabled and SSP is disabled in the PCONP register (

see LPC2104/2105/2106 user manual).

[12] To VSS.

8.1 Power consumption measurements for LPC2104/2105/2106/01

The power consumption measurements represent typical values for the given conditions.

The peripherals were enabled through the PCONP register, but for these measurements

the peripherals were not conﬁgured to run. Power measurements with all peripherals

enabled were performed with the SPI enabled and the SSP disabled. Peripherals were

disabled through the PCONP register. Refer to the

LPC2104/2105/2106 User Manual for a

description of the PCONP register.
