Ceramic oscillation
• fX = 2.4 to 8 MHz
• fX = 2.4 to 4 MHz
• fX = 4 to 8 MHz^Note
16 µs (fX = 4 MHz)
fX/8, fX/16, fX/64, fX/96, fX/128, fX/192, no carrier (high level)
9-bit programmable timer: 1 channel
Mask option
Internal
• VDD = 2.0 to 3.6 V
• 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)
TA = –40 to +85°C
• TA = –40 to +85°C
• TA = –20 to +70°C (with POC circuit)
• 20-pin plastic SSOP (7.62 mm (300))
• 20-pin plastic SOP (7.62 mm (300))
• 20-pin plastic SSOP (7.62 mm (300))
Note When the supply voltage is less than 2.7 V, it is necessary to design an application circuit to make the
RESET pin go low level.
