Support processor logic level down to 1.2V
Operational host VCCA 1.08V to 2V
Support 1.8V and 3.3V SIM card and eSIM (Class B and Class C)
Operational SIM VCCB 1.6V to 3.6V
Unidirectional level translation: CLK and RST
Bidirectional level translation: IO, accepts opendrain output from host
Shutdown sequencing per ISO/IEC 7816-3 deactivation requirement
Automatically initiated by pulling EN low (QFN package option) or SIM VCC power down (WLCSP package option).
Robust ESD protection
IEC 61000-4-2 level 4 on SIM side channels and SIM VCC: contact discharge ±8 kV, air discharge ±15 kV
Other pins: HBM ±2kV, CDM ±1kV
Support 10MHz clock speed
Low shutdown quiescent current, 1uA max at VCCA
Partial power down mode support
Output disabled and no current back flow when either supply is not present
Available in 2 package options: CPS2401B: WLCSP-9 1mm*1mm
CPS2401A: QFN-10 1.4mm*1.8mm*0.55mm
