-Extended: -40В°C to +125В°C
(except MCP1XX-195)
-Industrial: -40В°C to +85В°C (MCP1XX-195 only) Pb-free Devices The MCP102/103/121/131 devices are voltage
supervisor devices designed to keep a microcontroller
in reset until the system voltage has reached and
stabilized at the proper level for reliable system
operation. Table 1 shows the available features for
these devices. Package Types RST 1 VDD 2 3 VSS RST VDD VSS SOT-23/SC70 Applications: VSS 1
