Product details

What this 8-bit PIC brings to the board

The Microchip PIC18LF26K42-E/SS is an 8-bit MCU from the PIC XLP 18K family, built for applications that need moderate processing with low power and a wide temperature range.

64 MHz core — what that means for throughput

The 64 MHz clock rate is the top end for the PIC18 architecture. At this speed, the core executes most single-cycle instructions in about 15.6 ns. That is fast enough to handle 100 kHz PWM updates, software UART bit-banging at 115200 baud, or real-time sensor polling without a dedicated coprocessor.

Analog and peripheral mix for real-world signals

The on-chip analog subsystem includes a 24-channel 12-bit ADC and a single 5-bit DAC. That many ADC channels — 24 — is generous for an 8-bit MCU in a 28-pin package; it suits designs reading multiple thermocouples, potentiometers, or current-sense resistors. The DAC, though only 5-bit, can generate a reference or a simple analog output for trimming or alert thresholds. Peripherals include DMA, which moves data between memory and peripherals without CPU intervention — useful for buffering ADC readings or UART streams. The PWM module drives half-bridge or full-bridge converters, and the HLVD (high/low-voltage detect) monitors the supply rail for brownout or undervoltage conditions.

Microchip lists the PIC18LF26K42-E/SS as Active.

Frequently asked questions

How does PIC18LF26K42-E/SS compare to PIC16LF1559-I/SS?

The PIC16LF1559-I/SS is a lower--bit PIC with 32 MHz max speed, 14 KB Flash, 1 KB RAM, and 17 I/O in a 20-pin SSOP. The PIC18LF26K42-E/SS doubles the clock to 64 MHz, offers 64 KB Flash, 4 KB RAM, 25 I/O, and includes DMA and a 12-bit ADC with 24 channels. Choose the PIC18 when you need more memory, faster throughput, or richer analog — the PIC16 fits simpler, cost-sensitive tasks.
