Product details

20 MHz 8-bit core with industrial temperature range

The Microchip PIC16F648A-E/SO is an 8-bit PIC microcontroller from the PIC® 16F family, clocked at 20 MHz. It carries 7 KB of Flash program memory (4K x 14 words), 256 bytes of RAM, and 256 bytes of EEPROM — enough for moderate firmware payloads and non-volatile parameter storage.

Peripherals and I/O for control-oriented designs

Sixteen I/O lines are available in the 18-pin SOIC package, along with a UART/USART for serial communication. On-chip peripherals include a PWM module, brown-out detect/reset, power-on reset, and a watchdog timer — the standard set for cost-sensitive embedded control.

Frequently asked questions

Does PIC16F648A-E/SO have an internal oscillator?

Yes, the PIC16F648A-E/SO includes an internal oscillator, so no external crystal or clock source is required for basic operation. This reduces BOM count and board area.

What is the difference between PIC16F648A-E/SO and PIC16F648A-I/SO?

All other specifications — 20 MHz core, 7 KB Flash, 256 bytes RAM/EEPROM, 16 I/O, UART — are identical.
