POC circuit

Provided

Supply voltage

VDD = 2.2 to 3.6 V (fX = 2.4 to 4 MHz), VDD = 2.7 to 3.6 V (fX = 4 to 8 MHz)

Operating ambient

• TA = –40 to +85

°C

temperature

• TA = –20 to +70

°C (when using POC circuit)

Package

• 20-pin plastic SOP (7.62 mm (300))

• 20-pin plastic SSOP (7.62 mm (300))

Note It is necessary to design the application circuit so that the RESET pin goes low at a supply voltage of less

than 2.7 V.
