LPC540xx
32-bit ARM Cortex-M4 microcontroller
Table 18 shows the typical peripheral power consumption measured on a typical sample
at Tamb = 25 °C and VDD = 3.3 V. The supply current per peripheral is measured as the
difference in supply current between the peripheral block enabled and the peripheral block
disabled using ASYNCAPBCLKCTRL, AHBCLKCTRL0/1/2, and PDRUNCFG0/1
Conditions: BOD disabled; all oscillators and analog blocks disabled; all SRAM disabled except
64 KB SRAMX.
Remark: At hot temperature and below 2.0 V, the supply current increases slightly because of
reduction of available RBB (reverse body bias) voltage.
