E931.96有E931.96,E931.96A,E93196B53D E931.96B 多个版本，
按上面的型号顺序，是早期--最近出货的不同型号，都是同一颗料，

E93196B53D是规格书写的订货型号，其实是指E931.96B 
只要封装是SO8 一样用，可以互相直接替代，拍此链接目前发货E931.96B 

E931.96B-3uA低功耗的可编程PIR控制芯片
ULTRA-LOW POWER PIR CONTROLLER INTEGRATED CIRCUIT

General Description
The E931.96 is an ultra-low power motion detector controller integrated circuit. The device is ideally suited for battery operated wireless motion sensors that make use of an MCU for handling communication.
The MCU does not need to be active while the E931.96 does continuous motion sensing. It only activates the external controller, when motion is detected. Motion is signaled through the push-pull output (INT). The criteria for motion detection are programmable and can be changed by the external controller.
The E931.96 interfaces directly with up to two conventional PIR sensors via a high impedance differential input. The PIR signal is converted to a 14 bit digital value on chip.
All signal processing is performed digitally.
