Product data sheet Rev. 5 — 14 June 2011 11 of 47 NXP Semiconductors LPC2212/2214 Single-chip 16/32-bit ARM microcontrollers [1] SSP interface is available on LPC2212/01 and LPC2214/01 only. VSS 3, 9, 26, 38, 54, 67, 79, 93, 103, 107, 111, 128 I ground: 0 V reference VSSA 139 I analog ground; 0 V reference. This should nominally be the same voltage as VSS, but should be isolated to minimize noise and error. VSSA(PLL) 138 I PLL analog ground; 0 V reference. This should nominally be the same voltage as VSS, but should be isolated to minimize noise and error. VDD(1V8) 37, 110 I 1.8 V core power supply; this is the power supply voltage for internal circuitry. VDDA(1V8) 143 I analog 1.8 V core power supply; this is the power supply voltage for internal circuitry. This should be nominally the same voltage as VDD(1V8) but should be isolated to minimize noise and error. VDD(3V3) 2, 31, 39, 51, 57, 77, 94, 104, 112, 119 I 3.3 V pad power supply; this is the power supply voltage for the I/O ports VDDA(3V3) 14 I analog 3.3 V pad power supply; this should be nominally the same voltage as VDD(3V3) but should be isolated to minimize noise and error Table 3.
