Features & Applications
The PIC18LF2221-I/SS is a part of PIC18LF series 8-bit Microcontroller. It has 4 Kbytes of Flash Program Memory in a 28 Pin SSOP package. It has an industrial temperature range from -40°C to +85°C.

Ideal for connectivity applications that benefit from the availability of the double asynchronous serial port, the flexible synchronous serial port (I²C or SPI) as well as large amounts of RAM buffer memory and Flash program memory. These include instrumentation panels, TCP/IP enabled embedded applications as well as metering and industrial control and monitoring applications.

All of these below features make it ideal for battery powered and power consumption critical applications including instrumentation and monitoring, data acquisition, power conditioning, environmental monitoring, telecom and consumer audio/video applications.

Features:

  • Power-Managed Modes:
    • Run: CPU on, peripherals on
    • Idle: CPU off, peripherals on
    • Sleep: CPU off, peripherals off
    • Idle mode currents down to 2.5 μA typical
    • Sleep mode currents down to 100 nA typical
