PCA85063A Automotive tiny Real-Time Clock/calendar with alarm function 2 and I C-bus Rev. 4.1 16 September 2021 Product data sheet 1 General description 1 The PCA85063A is a CMOS Real-Time Clock (RTC) and calendar optimized for low power consumption. An offset register allows fine-tuning of the clock. All addresses and 2 data are transferred serially via the two-line bidirectional I C-bus. Maximum data rate is 400 kbit/s. The register address is incremented automatically after each written or read data byte. For a selection of NXP Real-Time Clocks, see Section 20.1. 2 Features and benefits AEC-Q100 grade 2 compliant for automotive applications High temperature operation range: -40 C to +105 C Provides year, month, day, weekday, hours, minutes, and seconds based on a 32.768 kHz quartz crystal Clock operating voltage: 0.9 V to 5.5 V Low current typical 0.25 A at V = 3.0 V and T = 25 C DD amb 2 400 kHz two-line I C-bus interface (at V = 1.8 V to 5.5 V) DD Programmable clock output for peripheral devices (32.768 kHz, 16.384 kHz, 8.192 kHz, 4.096 kHz, 2.048 kHz, 1.024 kHz, and 1 Hz) Selectable integrated oscillator load capacitors for C = 7 pF or C = 12.5 pF L L Alarm function Countdown timer Minute and half minute interrupt Oscillator stop detection function Internal Power-On Reset (POR) Programmable offset register for frequency adjustment 3 Applications Tracking time of the day Accurate timing Dashboard Infotainment unit Air condition Center stack Telematics Body control and battery management 1 The definition of the abbreviations and acronyms used in this data sheet can be found in Section 21.NXP Semiconductors PCA85063A 2 Automotive tiny Real-Time Clock/calendar with alarm function and I C-bus 4 Ordering information Table 1.Ordering information Topside Type number Package mark Name Description Version 063Q PCA85063ATT/A TSSOP8 plastic thin shrink small outline package 8 SOT505-1 leads body width 3 mm 4.1 Ordering options Table 2.Ordering options Minimum order Temperature Type number Orderable part Package Packing method quantity number 1 2500 PCA85063ATT/A PCA85063ATT/AJ SOT505-1 REEL 13 Q1 NDP -40 C to +105 C 1 Not Recommended for New Design (NRND).
