M440T513Y

Table 11. DC Characteristics

Note: 1. Valid for Ambient Operating Temperature: TA = –15 to 75°C; VCC = 4.5 to 5.5V (except where noted).

2. All voltages are referenced to Ground.

3. For BL and IRQ (Open drain); if pulled-up to supply other than VCC, this supply must be equal to, or less than 3.0V when VCC = 0V

(during battery back-up mode).
