The Microchip PIC18F27Q43-I/SS is an 8-bit MCU from the PIC® XLP™ 18F series, rated for Functional Safety (FuSa) applications. It runs at 64 MHz, giving it enough throughput for real-time control loops — think brushless-DC motor commutation, sensor fusion at a few kHz, or managing a small HMI with a character LCD. The 24-channel 12-bit ADC and single 8-bit DAC cover most analog sensor interfaces, so you can often skip an external ADC. The 28-SSOP package (5.30 mm width) is a compact surface-mount footprint that suits space-constrained PCBs.
Connectivity and peripherals — what is on the bus
The LINbus support is useful for automotive body electronics — window lifts, seat controls, or lighting modules — where a LIN node connects to a CAN backbone.
This is a part you can design into a new BOM today without planning a future migration.
Sourcing posture — quoted to order
Because the lifecycle is Active, there is no LTB risk and no urgency to stockpile — but if you need a production quantity for a build, send the RFQ and we will confirm the lead time and price.
