1.1 PIC16F17146 and PIC16F18146 Microcontroller Families

The PIC16F17146 and PIC16F18146 microcontroller families contain an enhanced mid-range 8-bit CPU core that reaches speeds up to 32 MHz. These microcontroller families support up to 28 KB of Flash, up to 2 KB of SRAM, and up to 256 Bytes of EEPROM and are available in 8-, 14-, 20-, 28-, 40- or 44-pin packages. They have a suite of analog peripherals that enable precision sensor applications. This small form factor, feature-rich device is well suited for low-cost, energy-efficient analog sensor applications with higher resolution requirements. The PIC16F17146 family of microcontrollers has one general purpose OPA, while the PIC16F18146 microcontroller family does not have OPA.

Figure 1-1 shows an overview of the PIC16F17146 and PIC16F18146 microcontroller families available in 8-pin to 40-pin (VQFN) packages with a memory range of 7 KB to 28 KB. The parts with different Flash memory typically also have different RAM and EEPROM.

  • Vertical migration is possible without code modification, as these devices are pin and feature-compatible
  • Horizontal migration to the left reduces the pin count and limits the available features in certain use cases
