Core specs and memory budget for the BOM line
The Microchip PIC16F18857T-I/ML is an 8-bit MCU from the PIC® XLP™ 16F series with a Functional Safety (FuSa) designation, running at 32 MHz. It packs 56 KB (32K x 14) of Flash program memory, 4 KB (4K x 8) of RAM, and 256 bytes of EEPROM — enough for moderate sensor-fusion or control loops without external storage.
On-chip data converters (24-channel 10-bit ADC, one 5-bit DAC) handle analog inputs without an external ADC.
ROHS3 compliant — no special handling for lead-free reflow.
