PCF85263A Tiny Real-Time Clock/calendar with alarm function, battery 2 switch-over, time stamp input, and I C-bus Rev. 5.2 22 September 2021 Product data sheet 1 General description 1 The PCF85263A is a CMOS Real-Time Clock (RTC) and calendar optimized for low power consumption and with automatic switching to battery on main power loss. The RTC can also be configured as a stop-watch (elapsed time counter). Three time log registers triggered from battery switch-over as well as input driven events. Featuring 2 clock output and two independent interrupt signals, two alarms, I C-bus interface and quartz crystal calibration. For a selection of NXP Real-Time Clocks, see Table 71. 2 Features and benefits UL Recognized Component (PCF85263ATL) Provides year, month, day, weekday, hours, minutes, seconds and 100th seconds based on a 32.768 kHz quartz crystal Stop-watch mode for elapsed time counting. From 100th seconds to 999999 hours Two independent alarms Battery back-up circuit WatchDog timer Three timestamp registers Two independent interrupt generators plus predefined interrupts at every second, minute, or hour Frequency adjustment via programmable offset register Clock operating voltage: 0.9 V to 5.5 V Low current typical 0.28 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) Configurable oscillator circuit for a wide variety of quartzes: C = 6 pF, C = 7 pF, and L L C = 12.5 pF L Packages offered: SI8, TSSOP8, TSSOP10, HXSON10 and WLCSP12 3 Applications Printers and copiers Electronic metering Digital cameras White goods Elapsed time counter 1 The definition of the abbreviations and acronyms used in this data sheet can be found in Section 23.NXP Semiconductors PCF85263A 2 Tiny Real-Time Clock/calendar with alarm function, battery switch-over, time stamp input, and I C-bus Network powered devices Battery backed up systems Data loggers Digital voice recorders Mobile equipment Accurate high duration timer 4 Ordering information Table 1.Ordering information Type number Topside Package marking Name Description Version PCF85263AT/A 85263A SO8 plastic small outline package 8 leads body width 3.9 mm SOT96-1 PCF85263ATL/A 263A DFN2626-10 plastic thermal enhanced extremely thin small outline SOT1197-1 package no leads 10 terminals body 2.6 2.6 0.5 mm PCF85263ATT/A 263A TSSOP8 plastic thin shrink small outline package 8 leads body width SOT505-1 3 mm PCF85263ATT1/A 263A TSSOP10 plastic thin shrink small outline package 10 leads body SOT552-1 width 3 mm PCF85263AUK F WLCSP12 wafer level package 12 cu pillars body 1.19 x 0.94 x 0.22 SOT2035-1 mm with 0.25 mm pitch 4.1 Ordering options Table 2.Ordering options 1 Type number Orderable part Package Packing method Minimum Temperature number order quantity PCF85263AT/A PCF85263AT/AJ SO8 Reel 13 Q1 NDP 2500 T = -40 C to +85 C amb PCF85263ATL/A PCF85263ATL/AX DFN2626-10 Reel 7 Q1 NDP 4000 T = -40 C to +85 C amb PCF85263ATT/A PCF85263ATT/AJ TSSOP8 Reel 13 Q1 NDP 2500 T = -40 C to +85 C amb 2 PCF85263ATT1/A PCF85263ATT1/AJ TSSOP10 Reel 13 Q1 NDP 2500 T = -40 C to +85 C amb PCF85263ATT1/AZ TSSOP10 Reel 13 Q1 NDP 2500 T = -40 C to +85 C amb 3 SSB PCF85263AUK PCF85263AUKZ WLCSP12 Reel 13 Q1 Dry 20000 T = -40 C to +85 C amb Pack 1 Standard packing quantities and other packaging data are available at www.nxp.com/packages/ 2 Discontinuation Notice 202104010DN drop in replacement is PCF85263ATT1/AZ.
