5 V tolerant inputs/outputs • 0 to 400 kHz clock frequency • ESD protection exceeds 2000 V HBM per JESD22-A114, 200 V MM per JESD22-A115, and 1000 V CDM per JESD22-C101 • Latch-up testing is done to JESDEC Standard JESD78 which exceeds 100 mA.
• Package offering: SO20, TSSOP20 DESCRIPTION The PCA9560 is a 20-pin CMOS device consisting of two 6-bit non-volatile EEPROM registers, 5 hardware pin inputs and a 5-bit multiplexed output with one latched EEPROM bit.
It is used for DIP switch-free or jumper-less system configuration and supports Mobile and Desktop VID Configuration, where 3 preset values (2 sets of internal non-volatile registers and 1 set of external hardware pins) set processor voltage for operation in either performance, deep sleep or deeper sleep modes.
The PCA9560 is also useful in server and telecom/networking applications when ...
