Key Features

  • 8-bit PIC18 core with 40 MHz maximum clock frequency delivering high computational throughput for compact MCU designs
  • Onboard 4 KB Flash plus 256 bytes EEPROM and 256 bytes RAM in space-saving 20-pin SSOP package
  • Integrated ADC enabling direct analog sensor interfacing without external conversion circuitry

Applications

The PIC18F1220-I/SS fits space-constrained embedded control applications including smart sensor nodes, handheld measurement instruments, and appliance motor controllers. With 40 MHz clock speed and 4 KB Flash, it handles real-time 8-bit control loops while the 256 bytes EEPROM stores calibration data across power cycles. The 20-pin SSOP footprint allows dense PCB placement in portable and wearable designs operating from 2 V to 5.5 V supply rails.

Frequently Asked Questions

How much on-chip memory does the PIC18F1220-I/SS provide and at what maximum clock speed does it operate?

The PIC18F1220-I/SS provides 4 KB of Flash program memory, 256 bytes of data EEPROM, and 256 bytes of RAM. It runs at up to 40 MHz maximum clock frequency, giving sufficient processing throughput for 8-bit control tasks such as sensor sampling, PWM generation, and serial communication.

For a portable measurement device powered by two AA batteries, how does the PIC18F1220-I/SS handle low-voltage operation?

The PIC18F1220-I/SS supports a supply voltage down to approximately 2 V, compatible with two depleted AA cells. Its integrated ADC and 256 bytes EEPROM for calibration storage make it practical for battery-powered instruments where reading analog sensors and preserving calibration across power cycles at low supply voltages are both required.

When would a designer select the PIC18F1220-I/SS over a 28-pin DIP PIC18 variant for a new PCB design?

The 20-pin SSOP package of the PIC18F1220-I/SS occupies roughly 40 percent less board area than a 28-pin DIP MCU. For designs where 4 KB Flash and 8-bit PIC18 performance are sufficient and PCB real estate is constrained, such as in wearables or dense industrial sensor modules, the SSOP-20 form factor provides a significant size advantage without sacrificing the 40 MHz clock capability.
