Electrical, Mechanical, and Thermal Specification

Intel® PXA270 Processor

Electrical Specifications

Table 5-2 shows each power domains supported voltages (except for VCC_MEM and

VCC_CORE). Table 5-3 shows all of the supported memory voltages and frequency operating

ranges (VCC_MEM). Table Note: shows all of the supported core voltage and frequency ranges

(VCC_CORE).

The operating temperature specification is a function of voltage and frequency.
