• Manufacturer Part Number: EM6603
• Description: Ultra Low Power Multi I/O Microcontroller
• Manufacturer: EM Microelectronic

Table 1. Pin Description
Figure 3.Typical Configuration
For Vdd less then 1.4V it is recommended that Vdd is connected directly to Vreg
For Vdd>1.8V then the configuration shown in Fig.3 should be used.
