Product details

8-bit PIC with LCD drive and 125°C rating

It integrates a segment LCD driver, a 20-channel 12-bit ADC, a single 5-bit DAC, and serial connectivity including I²C, LINbus, SPI, and UART/USART.

Peripheral set for panel and sensor applications

The on-chip LCD driver (supported by the Peripheral Pin Select feature) can directly drive segmented glass displays, eliminating a separate display controller in metering and control-panel designs. The 12-bit ADC with 20 channels covers multi-sensor acquisition, while the 5-bit DAC provides a simple analog output for set-point or bias generation.

It is ROHS3 compliant.

Frequently asked questions

What is the maximum frequency of the PIC16F19155-E/MV?

The PIC16F19155-E/MV runs at a maximum core speed of 32 MHz, which sets the instruction cycle time at 125 ns (4 clock cycles per instruction). This is sufficient for real-time control loops, serial communication at standard baud rates, and driving the LCD segment update without an external clock source.

What is the closest functional second-source for the PIC16F19155-E/MV?

The PIC16LF1559-I/SS is a pin-compatible 8-bit PIC from the same XLP 16F family, also running at 32 MHz with I²C, SPI, and UART. However, it has a lower temperature rating (85°C), fewer I/O (17), smaller ADC resolution (10-bit), and no LCD driver. For applications that need the 125°C rating or the LCD peripheral, the PIC16F19155-E/MV is the correct choice.
